From AJA Video Systems: The new FS-HDR real-time High Dynamic Range/Wide Color Gamut processor, co-developed with Colorfront, produces SDR to HDR, HDR to SDR, and HDR to HDR conversions. Bob Hudelson, FS-HDR Product Manager at AJA Video Systems, highlighted the processor's significant new features, including:
From Grass Valley: Bruce Lane, Manager of System Integration Sales at Grass Valley, discussed the impacts of 4K on today's broadcast environments. Where and how is 4K used today in production, from islands to full 4K Broadcast? What has the industry learned from early adopters? Why is timing so critical in 4K, what types of connections (4x3G, QUAD or 2SI, 10G, 12G, and 25G) are in use today and in the future? What other changes should the industry expect to see over the next few years regarding equipment (cameras, switchers, servers and replay)? Finally, HDR: what is it and how does that improve HD, 3G, and 4K images?
June 29, 2017
Karl Kuhn, Senior Video Systems Application Engineer at Tektronix, discussed the new methodologies needed from production to delivery of content in an IP end-to-end architecture. What do all the new buzzwords mean and how do we make sure it all works? To maintain network reliability in SMPTE 2022 and PTP deployments we need a stronger collaboration between broadcast engineers and IT engineers to bridge the gap between the SDI and IP worlds. Network continuity and proper buffering will promote smooth delivery of packets as we migrate away from black burst and tri-level and implement SMPTE 2059 Precision Time Protocol. We need to detect IP packet errors and monitor Packet Arrival Interval Time (PIT) and Time Stamped Delay Factor (TS-DF). Not all deployments will justify the migration to IP, so 12G SDI will become the typical architecture for some facilities. Smaller facilities and trucks may stay with SDI but need 12G SDI for UHD future proofing. These higher bitrates will require adherence to best practices. High Dynamic Range is considered the best bang for the bit but presents new end-to-end challenges. Delivering more detail in the blacks and the whites is the goal for a high quality of experience but getting the white levels correct is critical with brighter displays.

A multi-station FM channel combiner with a single feed line and broadband antenna provide a solution for the increasing demand of FM spectrum and tower space. Tightly spaced co-located channels require narrow higher order filters that quickly impact combiner efficiency and size to provide necessary transmitter isolation for IM suppression. Cross coupling has been used to improve isolation between channels, reduce filter order, and improve efficiency. Derek Small, Senior RF Engineer, Dielectric, was the presenter. Special guest Dielectric engineer Nicole Starrett also briefly touched on considerations for FM translators.

Operators who have significant investments in large-scale SDI plant are going to face technical and budget challenges as they transition to newer IP-based topologies while still maintaining current SDI workflows. This SBE presentation, given by Scott Barella, CTO of Utah Scientific, was prepared to provide some practical guidance for operators and system designers with a focus on constructing 'islands' within current infrastructures. Given that SDI is the predominant topology, the center of these plants lies within SDI routing cores. Therefore, any transition will have to address key SDI architectures and augment an existing plant. The paper addressed a number of key parameters such as control systems, SDI-to-IP conversion, and 12G SDI. The conclusion of the paper pointed to an 'island' approach as a practical means of providing a low-risk transition to the world of uncompressed IP video, audio, data and timing.
September 27, 2016
September's meeting was held in conjunction with the 2016 Media Resource Expo, in Danvers, MA. We had two presentations, from Nevion and Sony.
Nevion: Today we can transport signals over not just dark fiber or highly resilient telco circuits but over MPLS and Metro Ethernet circuits, and to the horror of many, the public Internet. Signals can cross over disparate networks and need to be at a location or locations, in a deterministic manner to meet on-air requirements. How do broadcasters get the same confidence level and reliability out of newer transport media and attain the benefits of IP technology? Steve Sloane explored these questions.
Sony: Hugo Gaggioni discussed how to practically use HDR in a live application. HDR is often discussed as something that can be used in cinematography, but using it in a live environment requires different techniques and equipment. Hugo was present at the recent Summer Games and also discussed how Sony helped NBC create a live 4K HDR program there. This event used some equipment specifically for HDR that up to that time had not been seen outside of controlled demo environments, but will soon become commonplace.
June 30, 2016
Karl Kuhn, Senior Video Systems Application Engineer, Tektronix, gave a tutorial on the practical aspects of audio to maintaining a high level of Quality of Experience for your content from End-to-End. If the content must also be CALM compliant then 1770-3 testing must be applied.
It all starts in production and post with single, multichannel or surround mixes. Visualization tools are helpful to assist in creating the proper artistic mix results. If the content is file based then automated QC processes can be used to find clips, mutes, silence, CRC errors, and if needed, CALM compliance. Automatic correction for CALM compliance can be applied. Check to see how well CALM tracks with Dolby Dialnorm. Audio must survive the compression and transmission layer. Audio quality should be tested as close to the end user as possible with logging of alarms and trends.
Karl stepped through the process to understand the available tools to maintain and protect the quality of your brand.

What's hot these days in the over-the-air television business? Plenty, but some topics are especially timely. With the incentive auction underway, stations are very concerned about the possibility of changing channels, and that of course means transmitters. And what signals will those new boxes transmit? ATSC 3.0 is a good bet for the near future. Joe Turbolski, Director of Sales Operations at Hitachi-Comark, presented an overview of both of these topics: new solid state UHF amplifier technologies for more reliable and efficient transmitters and the forthcoming ATSC 3.0 DTV standard.
April 28, 2016
As new IP technologies and production workflows emerge, the live video industry is changing. Dr. Andrew Cross, President and CTO of NewTek, one of the leading proponents of and innovators behind IP-based productions, discussed the significance of the industry's shift to an ultra-connected production workflow. He shared his vision for the future of the video industry and showed how NewTek products with their open Network Device Interface makes the transition to IP easier and works with existing standards and other systems.
March 31, 2016
Live Video over IP has exciting possibilities for broadcast infrastructure, but how do we insure the reliability and interoperability among equipment systems, and how do we monitor these live streams? John Shike, from Snell Advanced Media, talked about an approach to routing with COTS IP switches that allows integration with SDI and provides clean switching, the role of open standards including VSF TR-03 that Alliance for IP Media Solutions (AIMS) is promoting, and how to monitor video, whether the stream is SDI, file-based, or video-over-IP.

For many broadcasters, the largest footprint for fault monitoring is their transmitter remote control; for some it's a primary application. Going forward, fault monitoring will grow in radio and TV facilities as applied in some form or another to the studio, master control room, power and facility management as well as network health monitoring. Many monitoring applications in use are provided by proprietary hardware manufacturers and some are facility or network based. SuiteLife System's national sales director Kenny Miller's presentation outlined the proper feature sets for monitoring systems and how well consolidated monitoring environments can work. Properly applied, the technology results in a more efficient response by engineers to fault occurrences. With the aid of visual data displays operators may be involved, allowing engineering a greater focus to support the business of news or program production. Kenny showed how the integration of disparate systems and equipment across multiple site networks can bring Management, Monitoring and Control to a single screen.
January 28, 2016
There is an on-going shift in the way broadcasting handles live transmission and distribution and what it uses as a transmission path. In lieu of expensive paths like fiber or satellite, more and more stations are leveraging IP for low latency primary and back up contribution and distribution. Emeka Okoli, Solution Specialist, Raymond Thompson, Marketing/Products, from Zixi, LLC looked at the challenges and benefits to making this switch and discussed a few IP enabled work flows.
December 10, 2015
Television Broadcast is undergoing historic changes. Transmission encoding efficiencies are much higher than when the ATSC standard was created 20 years ago. Because of this there is a push to reduce the bandwidth used by broadcast, first with the possible consolidation of stations using the existing ATSC standards, followed by a later transition to ATSC3 which will greatly multiply both the encoding efficiency and the modulation efficiency. In the interim broadcasters must rely on careful utilization of the available bandwidth. Michael Guthrie, Technology Specialist at Harmonic, looked at the statistical multiplexing process and ways to measure the utilization of bandwidth and picture quality.
Special Feature: Harmonic had a live demonstration of channel sharing and multiplexing at the meeting!
October 27, 2015
This month's meeting was held in conjunction with both the Media Resource Expo and the SBE Ennes Workshop. Too big for just one presentation, we had two!
Utah Scientific's presentation detailed the emerging trends for moving real time, uncompressed video over Ethernet links as opposed to the standard SDI links in use today. It covered networking standards, the several competing protocols for uncompressed video, methods for cleanly switching between sources, timing and other items relevant to the transition to IP.
● IP Ethernet versus SDI
● Basics of SDVN
● Current standards of SDI over IP and their comparison
September 24, 2015
Video walls and monitor clusters are standard fare on today's news sets. Set designers have gotten more creative on orientation, aspect ratios, and even shapes on these video walls, causing technical nightmares for the engineers responsible for feeding signals to them. The number of displays of each set also becomes a challenge to the operations team that needs to manage the content fed to them. Bob Valinski, director of sales at Orad, presented short case studies on new sets built at broadcasters such as The Weather Channel (108 monitors on set), Sportsnet Toronto (13,000 sq. ft. studio with a mixture of plasma displays and LED video walls & floors), MLB Network (entire studio lined with LED walls), and The Late Show (mix of LED walls and 3D projectors in theater). He focused on managing content and aspect ratios, as well as latency and other issues.
June 25, 2015
The FAA (and FCC) has been busy proposing and making changes to the rules governing the lighting of broadcast towers. Les Kutasi, of Dialight, talked about what tower owners need to know about the current rules for obstruction lighting, and the new rules to be adopted in the future. He discussed the options owners have for their towers regarding changing their lighting configuration. Highlights included:
● FAA / FCC new rules on light configurations
● How to update your lighting configuration with the new rules
● Explaining the different types of tower lighting options
● What options the market place offers for tower lighting
● What Dialight has to offer for tower lighting
May 28, 2015
More and more stations are turning to IP delivery of program audio and data to their transmitter sites. This has come about due to many factors, chief among them:
● New 950 MHz frequency slots are difficult to find in most markets now.
● The amount of audio and data that needs to be delivered to the transmitter has challenged the limits of conventional 950 MHz systems.
● Point-to-point service - T1 and equalized lines, for example - are being abandoned by traditional providers as they are costly to implement and maintain.
● The lower cost of IP connectivity and abundance of bandwidth available to broadcasters have made this transport medium a very attractive alternative to "conventional" STL links.
There are pitfalls using IP, however, and broadcasters must utilize appropriate error mitigation techniques to insure that their audio and data arrives at the transmitter site in useful form. Ted Nahil, Business Development Manager, Intraplex Products, discussed error mitigation techniques such as forward error correction and stream splicing that help guarantee proper delivery of audio and data over IP to a broadcast transmitter site. He also touched on the requirements to move MPX over AES-192 from a studio site to a transmitter site over an IP circuit.

You need to get your HD video signal
from here to there, without compression and without delay, and you
can't run a cable, copper or fiber. How about a millimeter-wave 60
GHz wireless system? HXI, a manu-facturer of broadband digital
radios, will demonstrate its GigaLink HD, the first FCC-approved
unlicensed full bandwidth transport system for HD and 3D-HD (dual
channel) video. Operating at 1.485 Gbps per channel, the radio
ensures the absolute lowest latency of any SMPTE 292M/372M radio.
Range is up to 500 meters (1640 feet).

Broadcast production has evolved greatly over the past few years with no slowdown in sight as viewing habits continue to move toward a more mobile society. Traditional broadcast is no longer driving the needs, and the days of “black box” master control are over. The drive for more content delivered in more places and at any time is overwhelming. This all leads to new considerations and requirements when architecting your SAN, including performance, accessibility, collaboration, distribution, archiving, and more.
Chris Duffy from Quantum discussed challenges driving the consideration and development of next generation SAN base broadcast workflows. Osvaldo Alvarez from IMT presented a real customer case study that details the challenges faced, troubleshooting initiatives, and corrective actions taken that completely turned around an underperforming broadcast production workflow.
February 26, 2015
The amount of data broadcasters deal
with has grown by so much over the past decade that long-term
storage has become a significant issue. The ability to send and
retrieve data to and from archives easily is no mean feat.
January 29, 2015
Ed Miley, Sales Engineer at Grass Valley (with the Telecast Fiber line) presented a case study of what he did at Gillette Stadium during the past few weeks, servicing news media with fiber, and discussed how and why fiber network capabilities there needed to be expanded.
Bruce Lane, Director of Sports Market Development for Grass Valley, followed with a presentation about 4k for live sports production, and also spoke about High Frame Rate (super slo-mo) video.
December 11, 2014
The move to Channel in a Box and
Integrated Channel Playout (ICP) has presented new workflow
challenges for broadcasters and playout facilities. As
traditional tools that used to dominate master control rooms, such
as dedicated graphics, branding systems and MCR switchers, melt away
into integrated systems, the tools to deal with live cut-ins,
sporting events, or scheduling mishaps have moved from familiar
tactile panels to awkward mouse and keyboard clicks. At the
same time, these changing technologies have presented new
opportunities for workflow optimization and intelligent function
integration. The power of ICP is bringing more production-like
workflows into the master control room, blurring the lines where
production control ends and MCR begins. The MCR of yesterday is
rapidly evolving to become an iMCR - an Integrated Master Control
room. Joe LoGrasso of Digital Glue and Bill Cordo and Brian
Pelletier of Harmonic discussed the evolution of the MCR and how ICP
solutions can help build a more powerful, efficient iMCR to unlock
new revenue streams and save on operational and capital
October 30, 2014
Tedd Tramaloni and Pete Ross from Ross video discussed enterprise-wide control and monitoring solutions, focusing on DashBoard, Ross Video's free, open-forum software that allows facilities to not only monitor and control Ross' and certain third-party devices, but also create custom, application-specific control panels that can be deployed throughout the plant.
Dashboard started out as a control and monitoring system for Ross' terminal gear, but has become much more widespread and full-functioned than that and now can be used to control virtually all its products, as well as those of some third-party manufacturers who have either adopted it, or allow for remote control using standard protocols such as VDCP. Thus, using Dashboard, a facility can do much more than simply monitor Ross gear cards, opening up the possibility of "hybrid" solutions that combine aspects of automated and manual control for not only production operations, but enterprise-wide systems as well.
Tedd discussed (amongst other things) three levels of production automation we're seeing in the industry:
● Full up production automation where everything is coded and the automation usually controls everything.
● Not quite full up production automation, where graphics are controlled via MOS, but with a highly integrated switcher with audio, graphics and robotic camera integration
● Dashboard assist, controlling, for example, graphics, or a portion of the production from Dashboard GUI panels, like Ross' Legislative control system.

A four-fer from the Telos Alliance!
First, John Bisset shared some of his famous tech-tips for radio and TV engineers. Second, Ken Tankel discussed some of the considerations for delivering quality audio in our regulatory environment. Digital television has the capability to deliver multi-channel audio to the home with wider dynamic range and frequency response and lower noise and distortion then has ever been possible before. Does the CALM Act and the related FCC regulations limit the quality of audio to the home? Third, special guest Telos Alliance CEO and Omnia Audio founder Frank Foti gave a brief talk recounting the history of the Telos Alliance, along with some advance information about what's coming in the near future. And fourth, Telos brought the "Broadcast Audio Fanatics Demo Van" to the meeting, stocked with equipment from Linear Acoustic, Omnia, Axia, and Telos. It has driven to 32 states in the past year, but this is the first time it was in New England.

Steve Lampen, Multimedia Technology Manager and Product Line Manager for Entertainment Products at Belden, told us "Here Comes Ethernet AVB!" Ethernet has been around since 1973, and you're probably aware of many companies that have struggled to make it work for audio and video applications. But those are proprietary systems where often Box A can't talk to Box B. So IEEE, which owns the Ethernet standard, has been working on a re-write of the Ethernet standard called 802.1BA AVB, and the AVB is for audio and video bridging. Audio is easy on AVB, even hundreds of channels. Video is harder to network than audio. And, with the progression from HD to 3G to 4K, it's going to be even harder, not easier. On the other hand, 40 gigabit data networking (and 100 gigabit) are also coming soon. There's even a "Generation 2" of AVB coming called TSN ("Time Sensitive Networks"). All these were covered in Steve's presentation. Finally, this new standard may herald a new way to design, install and operate audio and video facilities.

Recent history has shown it is not a question of if, but when an emergency will occur requiring broadcasters to be prepared, and sometimes creative with their efforts to stay on the air. Recent disasters from Hurricane Irene to Hurricane Sandy have made many New England communities realize how important radio really is during a disaster. It saves lives. The recent proliferation of IP Based STL's has opened new opportunities for IP Based STL's. Whether it is a land line based solution or an over the air microwave link with wideband IP connectivity, the new lines of IP Based codecs offer broadcasters new possibilities for maintaining bi-directional connectivity to their transmitter sites not only for audio, but control and monitoring as well. But we must have multiple layers of back-up and redundancy if we are going to rely on IP. We cannot afford to be off air during a disaster.
Tieline offers innovative and flexible solutions for IP connectivity and Mary-Ann Seidler, Vice President of Tieline, discussed the new products available today to help prepare for emergencies as well as discussed what worked and what didn't work for broadcasters during recent disasters. Case studies from the stations in New Jersey that were affected by Hurricane Sandy were examined.

As playout facilities make the transition from SDI to file-based infrastructures, one of their biggest challenges is dealing with a wide range of file formats. For playout applications this goes beyond audio and video, and must include ancillary data such as captions, AFD and V-Chip codes amongst others. Aimed at engineering and operations managers involved in broadcast playout, this presentation, by Joe LoGrasso, Director for Strategic Accounts at Miranda, explored the challenges involved in accommodating these different file formats. Joe covered:
● Wrappers and codecs most in use today
● Considerations for choosing a file format
● Strategies to lower operational costs and risks at playout
● Wrapper, video & audio codec families and their key features; ancillary data carriage
● Essence conversion, re-wrapping and transcoding; hardware, software and hardware-accelerated software
● Considerations for choosing a file format; conversion at playout versus file normalization
● Opinions and conclusion: the law of moving parts

This coming June is the new deadline for broadcasters to be CAP-compliant. CAP (Common Alerting Protocol) is the latest incarnation of the EAS system, which itself is the descendent of emergency broadcasting procedures going back to CONELRAD (Control of Electromagnetic Radiation) in the 1950's. Are you ready? Were you ready for the nationwide test last November? That one didn't go so well, for a number of reasons. Mark Manuelian, our local EAS expert and chair of PEPAC (Primary Entry Point Advisory Committee), discussed the test, its results and ramifications, the new CAP system, and more.
Late breaking addition: By now you've surely heard about the Great 2012 Easter Antenna Burnout that affected four of the major Boston-area broadcasters. We updated you on the causes and progress in repairing the shared antenna system.

CALM down. On December 13, 2011 the FCC released the rules governing commercial loudness. The requirements vary depending on the station size and the source of the programming.
The “Safe Harbor” provision of the rules allows the program provider to certify that the material they supply conforms to ATSC Recommended Practice A/85. Not all programmers will do this, and there is always locally produced material. As with all FCC rules, it is ultimately the station’s responsibility to demonstrate compliance. This presentation covered what these requirements are and how you can show you are meeting them.

Did I just hear someone say "tape was easier?" Well, sometimes file-based commercial delivery and ingest do get a little messy. Today, master control operators have to deal with various delivery services, methods, file formats, codecs, transcoders, electronic dub lists, and the magic word that can hopefully tie it all together: metadata. But the processes involved are far from uniform. Cris Nuernberg from Floripa Integration discussed this topic and introduced ideas and solutions that may enhance operations at individual stations. Perhaps it's time to provide the correct tools and standard procedures that can properly hand traffic back to the Traffic department. What if operators could open one system and all spots were there, waiting for them? That would be easier than tape! http://floripaintegration.com/r/N6c2q0I

Chris Regan, North American Sales Manager, APT Limited, took a look at private IP links, Metropolitan Ethernet links, and the first wide scale North American deployment of MPLS virtual network links for IP audio distribution.
By now most of us have heard about IP audio and many are beginning to deploy it in various ways. The majority of deployments so far have accepted compromises in order to achieve specific goals, such as better remote access (for remotes), or to achieve connections at the lowest possible cost (for low cost backup or repeater STLs). However, when you have read about Audio over IP you will have noted that a frequent caveat is that circuits with proper Quality of Service (QoS) are recommended for pro-grade applications.
The application of these network technologies for high quality compromise-free distribution of audio were explained in detail. In addition, these technologies were contrasted with the IP techniques designed to work over compromised networks and the advantages and disadvantages of each approach were discussed.
May 28, 2009

Ken Freed, New England District Sales Manager for JVC, gave a presentation about JVC's ProHD line of cameras. JVC has a range of HD products for ENG and studio applications at the most cost effective price points in the history of our industry. As a result, for the first time JVC HD products are “on the air” in major markets every night. The reasons for this success come from JVC's understanding of MPEG and from advanced mathematics in their cameras along with their implementation of native HD as 1280x720p60. JVC's effective low-bandwidth native HD implementation is a perfect fit for the Native File Workflow model evolving in 2008 as mid-market stations anticipate the costs of their HD build-outs.
John Wood, Director of Technology, Microwave Radio Corporation, presented MRC's take on the new technologies that will allow TV stations to send audio, video, and data from their ENG truck to the studio using IP file transfer techniques.
With the broadcast market looking to capitalize on multiple distribution schemes including off-air, cable interface, and multicast, the ability to monitor, manage and troubleshoot across these technologies is more than not getting caught with your pants down. It’s good business. As engineers, you need to get to the bottom of a revenue interrupting problem fast whether the issue is in your plant, or if it comes to you from outside.
Dave Musil of Sencore presented the MSA1850-P. The media service analyzer interfaces ASI/310M, 8VSB/QAM, and IP. You can remotely access the unit using a simple web browser from anywhere on the web.

PESA-from Com-Tech to QuStream, a journey from the Midwest, to Spain, and back again. Distributed Audio Routing - More sources and destinations, less real estate. CWDM Fiber transport-Bringing different routers together. Fiber to copper, copper to fiber, without the external frames. Fortel - Beyond the Y-688: more glue, smaller space. All this and more from Keith Andoos, Northeast Sales Manager of QuStream.
A few years ago, the message was to build a 1.5 Gb/s infrastructure even if you were only planning on a 270 Mb/s SDI system. This allowed easy migration to HD when required and affordable. HD is now common. It is time again to think about doubling the bandwidth of your video infrastructure. SMPTE 424 supports 1080P video formats and uses 3 Gb/s video transport. So, now is the time to start thinking about a 3 Gb/s plant. Randy Hall, Senior Systems Engineer at NVISION covered some of the aspects of implementing 3 Gb/s data rates in their video routing products and video systems, and what may exist beyond 3 Gb/s.
Can you use Category 5 or enhanced versions (5e, 6) to carry analog and digital audio? Or analog or digital video? How about S-video, RGB or VGA? Or broadband/CATV? Of course you can! For some applications, baluns are required. Exactly how to use it, and when not to use it was discussed by Steve Lampen of Belden.
Peter Burk, from Burk Technology, gave a presentation on the ARC Plus, a next-generation transmitter remote control system for full-time, multi-site or dial-up operation. Taking advantage of the scalability of IP, the ARC Plus connects an unlimited number of sites, each with up to 256 channels of metering status and command. Access the entire system from the front panel of any unit, take control using a Web-browser or PC software, or dial in to your system over the phone. With ARC-16 backwards compatibility, the ARC Plus allows broadcasters to advance their facility management operation incrementally, protecting the station’s hardware investment.
Robert Yankowitz, RF Systems Manager for the Boston CBS television stations and WBZ-AM, presented a quick tour of the WBZ transmitter site in Hull (with photographs of that historic site), and discussed theory and practice of AM directional antennas, including several methods of calculating their patterns.

Cedric Taylor from Mackay Communications presented an overview of Inmarsat’s BGAN (Broadband Global Area Network) service. BGAN allows broadcasters to send broadcast quality voice, data and video from remote locations at a lower cost. BGAN provides integrated voice, high-speed data, fax and IP (Internet Protocol) channels for large files and video in a single compact package. BGAN allows broadcasters to access information, and send high quality voice and broadband data from almost any location. With a single BGAN terminal, broadcasters can simultaneously make a call, download or send data, and access the internet. BGAN terminals can support single or multiple users, and they can also support external devices such as telephones and hands-free headsets. Broadcasters are using BGAN for remote broadcasts and emergency communications, and the technology can benefit both radio and television operations.

SONY has been a visible leader in the development of MXF, which is being widely accepted as the standard for interchanging media and metadata. The standard is also promoted by the Pro-MPEG forum, the EBU, and the AAF Association. MXF allows the user to store metadata and media-data in one file and/or stream. This is achieved by "wrapping up" all data (media and metadata) in a standardized, hierarchical way.
The 2 GHz BAS transition was clearly one of the hottest issues at NAB. This month, Wolf Coach, one of our own local companies, provided some very interesting facts relative to the current Nextel plan for inventory verifications and upgrades.
