Timing is Everything in Packet Video Whitepaper by Chuck Meyer, Chief Technology Officer - Core Products, (GVB-1-0476A-EN-WP) File size: 754.6 KB, posted Oct 31 2014 Video production relies on precise timing. Every pixel has to align, and packet video is no exception. Clearly defining the issue is crucial to determine the best approach to timing. Even with SDI video, line buffers are commonly used in video processing equipment. The delay is short, about 15 microseconds, and inexpensive with today's technology. As 4K UHDTV increases in resolution and frame rate, the line time will decrease. An 8K picture at 120 Hz will require just under 2 microseconds. And a pixel time is 250 picoseconds, which is vastly less than transit time for video signals, whether packet based or baseband. No matter how you measure it, the timing resolution required to produce video is much less than the transit time to move it around the facility. Buffers of some type will almost always be necessary.
Ethernet Technology Trends Whitepaper by Chuck Meyer, Chief Technology Officer - Core Products, (GVB-1-0475A-EN-WP) File size: 565.8 KB, posted Oct 31 2014 If we're going to base our broadcast industry assumptions (and hopes) on what the Ethernet can deliver in terms of connectivity, transport and the IP technology that runs on it, we need to examine where it's heading. Can it cope? Will it cope? Let's find out by understanding some fundamental truths of current and forecast trends for the Ethernet and the traffic lanes it provides for data signals.
Television Playout Goes Green Whitepaper by Marco Lopez, Senior Vice-President - Infrastructure & Monitoring, (GVB-1-0294A-EN-WP) File size: 932.8 KB, posted Dec 05 2014 As broadcasters strengthen their environmental credentials, and also look ahead to potentially higher electrical costs under 'cap and trade', they are now widening their perspective on energy saving to address the whole television process, from creation to transmission. This new emphasis on energy and space efficiency is now even impacting areas with lighter electrical consumption, such as playout equipment.
Streamlining HD Monitoring with Media Fingerprinting by Marco Lopez, Senior Vice-President - Infrastructure & Monitoring, (GVB-1-0291A-EN-WP) File size: 706.1 KB, posted Dec 05 2014 Lowering the operating costs of television playout has become something of a mantra across the television industry, and it has been especially evident in playout monitoring. Since monitoring has traditionally been labor-intensive and also prone to human error, it has been a natural focus for many streamlining and automation projects.
The widespread adoption of multiviewers over recent years, as well as IP-based facility monitoring with signal probing, has opened up new, more efficient workflows. A single operator can now manage and monitor complex systems efficiently, with a consequent large improvement in productivity.
Stereoscopic 3D Channel Branding: Controlling Z-depth Whitepaper by Michel Proulx, CTO, (GVB-1-0290A-EN-WP) File size: 1.0 MB, posted Dec 03 2014 The emergence of stereoscopic 3DTV as a practical option for broadcasters has opened up a whole new set of issues in relation to best practises for channel branding graphics. Key issues include where to place the 3D graphics in terms of the perspective, or Z-depth, for optimal viewing, and how to control the Z-depth of graphics during playout to compensate for changes to the program perspective.
Stereoscopic 3D Channel Branding for Live Events Whitepaper by Jason Barden, Product manager, (GVB-1-0289A-EN-WP) File size: 772.8 KB, posted Dec 03 2014 One of the biggest, if not the biggest, opportunity for stereoscopic 3D television is live events, such as sports and concerts. However, controlling 3D channel branding graphics in a live environment presents many challenges in order to avoid awkward perspective effects. For instance, operators need to decide where to place the 3D graphics in terms of the perspective, or Z-axis-positioning, for optimal viewing, and how to control the Z-axis-positioning of the graphics during the program to compensate for changes to the perspective.
Media Fingerprinting is an emerging technology that is gaining momentum and has far reaching benefits for content creators, providers and distributors alike. What is Media Fingerprinting and what are its current applications? How could standardization help promote this useful technology? This paper will address all of these issues and provide some answers.
Hybrid Routers: A New Era of Routing Whitepaper by Sara Kudrle, Sr. Software Engineer and Charles Meyer, Sr. Vice President - Router and Control, (GVB-1-0278A-EN-WP) File size: 515.1 KB, posted Dec 08 2014 When embedded audio first came about it was considered a universal solution for many audio woes, for which it has been very useful. However, as is the case with many new technologies unforeseen problems may arise, specifically, when the embedded content needs to be manipulated. Additionally, video and audio control rooms have to use both embedded and discrete audio coming from sources such as microphones.
Yes. By combining traditionally external processing equipment with discrete audio and video routers we have entered a new era in routing; the era of the hybrid router.
Crafted Transmission for Multimode Distribution Whitepaper by John Wadle, VP of Technology - IT-based systems, (GVB-1-0275A-EN-WP) File size: 679.7 KB, posted Dec 04 2014 During the past ten years we have seen increasingly rapid advances in digital methods of video recording, storage and distribution. During this same period, the technologies available for the transport of digital data over both wired and wireless media have evolved to provide dramatic increases in available bandwidth at substantially lower cost. One of the most visible results of the confluence of these two trends is the explosion of relatively low cost consumer electronics for the reception, storage and playback of video content.
The Road to UHDTV Whitepaper (GVB-1-0270A-EN-WP) File size: 1.0 MB, posted Dec 11 2014 Television's next evolution, while its end result might be deemed revolutionary by some, is Ultra High Definition TV (UHDTV), the next improvement in HD. While the major standards surrounding the technology have been identified and many have been worked out, the name, oddly enough, is still in flux. For production, we refer to it as 4K; CE manufacturers call it Ultra High Definition (UHD); the Society of Motion Picture and Television Engineers (SMPTE) calls it UHDTV1 or 2160p (UHDTV2 describes 8k). For purposes of this paper, it will be labeled UHDTV or UHDTV 4K.
Centralized Multistation Operation with iTX Whitepaper by John Wadle, VP of Technology - iT-Based Systems, (GVB-1-0252B-EN-WP) File size: 1.9 MB, posted Mar 04 2019 About ten years ago, following the widespread deployment of master control automation systems in the US station market, the concept of centralized operation of multiple stations under common ownership was evaluated and, in several cases, deployed. The results of these initial multistation centralizations were mixed, and a primary objective of significantly lower operating costs was not always achieved since the resultant savings in manpower proved inadequate to offset the cost of the required communications links at 1990s' rates. Nevertheless, several of these centralized projects continue in operation today, and a few have been expanded or upgraded with newer technology. Overall, however, the anticipated substantial benefits of station group centralization have not been fully realized, and broadcasters continue to look for new models to improve their bottom line through reduced costs.
An Easier Transition to Fiber Using SFP Modules Whitepaper by Chuck Meyer, Chief Technology Officer - Core Products, Grass Valley, a Belden Brand, (GVB-1-0250A-EN-WP) File size: 1.0 MB, posted Nov 25 2014 Many broadcasters are upgrading the video/audio backbone interconnections between their different facilities such as studios and control rooms to support 3G, and this is creating an increased demand for fiber-based infrastructures to support the higher data rates. Fiber offers many substantial advantages over traditional coax, including high performance over longer distances, virtually unlimited bandwidth and reduced sensitivity to electrical interference. It also offers greater space and weight efficiency. Fortunately, it has now become much more affordable and easier to use, especially with the availability of Small Form-factor Pluggable (SFP) fiber modules, and this has led to it becoming the de-facto standard for 3G signals.
