New Bay Media IP Migration White Paper

For the past three decades, the television industry has been dominated by two major technology transitions. The first, from analog to digital video signals, began in the 1980's and is now essentially complete — the methods used to deliver video to consumers have become almost exclusively digital, and professional production systems being sold today are based on digital technology. The second, from SD to HD, began about a decade later and has penetrated the television market to the extent that virtually all new professional equipment and services are designed to support HD resolution.

With both of these transitions nearly concluded, the television industry is now faced with two more technology upheavals: migrating from SDI to IP-based studio infrastructure, and upgrading video signals from HD to 4K/Ultra HD. Both of these technologies are poised to once again revolutionize the production and delivery of television content. But, just like the earlier technology migrations, the transitions to IP and 4K/UHD will take time, and each video facility will no doubt proceed at its own pace.

The Road to UHDTV White Paper

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.

How 4K UHDTV, 3G/1080p and 1080i Will Shape the Future of Sports Television Production White Paper

Presented in depth in this paper is the significant growth in preference toward the 3G/1080p and 4K UHDTV formats. This is telling, considering that 3G/1080p is a format that currently has fairly limited applications in broadcast while 4K UHDTV is a format with no current transmission mechanism to bring content into homes.

Hybrid Routers: A New Era of Routing White Paper

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.

Television Playout Goes Green White Paper

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

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.

Overcoming the Burden of VOD White Paper

For many broadcast engineers and operations managers, the number one headache right now is generating ondemand content. It takes up lots of their time, while generating low revenue streams in comparison to traditional, linear television. Evidently, this is not a viable long-term option, and this has prompted considerable interest in speeding the creation of nonlinear content, as well as improving the associated revenues.

Crafted Transmission for Multimode Distribution White Paper

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.

Stereoscopic 3D Channel Branding for Live Events White Paper

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.

Maintaining Frame-Accurate Operation in iTX White Paper

The iTX software is designed to provide frame-accurate, scheduled playout of video and audio content using a standard IT hardware platform operating under Microsoft Windows Server. This simple statement often raises a question regarding the ability of any software application to maintain frame-accurate operation in a non-real-time environment such as that provided by the Windows Server operating system.

To address this question as it applies to iTX, it is necessary first to understand the processing environment provided by Microsoft Windows Server and other software operating systems, as well as the capabilities and limitations of modern IT hardware.

Centralized Multistation Operation with iTX White Paper

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 White Paper

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.

The Changing Dynamics of Digital Media Publishing, Live Streaming and Social Interactivity “BRIEF” White Paper

Digital media ecosystems are transitioning at the speed of light to meet consumer demand for video consumption anywhere, anytime and on any device.

This dramatically impacts broadcast media producers and distributors as workflows that were once facility-centric are now expected to seamlessly address and integrate with "Software-as-a-Service" (SaaS) or "Platform-as-a-Service" (PaaS) online cloud-based solutions. Systems for transcoding, targeted advertising, ad decisioning, rights management, social media, content management and online video all need to be considered for content delivery.

There are significant challenges facing broadcasters as they drive
both local and network facilities to maximize efficiencies and drive
throughput to address the demands of digital media.

Timing is Everything in Packet Video White Paper

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.

Truck Challenge White Paper

The purpose of this study was to measure the technological challenges of mobile TV production. Why measure problems? The reason is simple. If we can better understand the problems that most frequently occur during a mobile production, we will be better able to anticipate those challenges and counter them. Or, as the father of modern management, Peter Drucker, once said, "That which gets measured, improves."

The study targeted high-end sports production professionals involved in mobile production. Our goal was to aggregate the experience of hundreds of people who work in, or manage, mobile productions, and arrive at a universal truth about which operational areas are most challenging. We interviewed industry experts from mobile production companies both large and small, and surveyed professionals at broadcast and cable networks, as well as mobile production companies.

Switching and Routing Signals in the IP Transition White Paper

Video signals need bridges to get, well, to the other side. However, what constitutes the "other side" is becoming increasingly ambiguous. Hence, a video bridge essentially needs to be directionally all-encompassing, meaning that it is capable of allowing a signal to enter, traverse and exit at any point — or points — required.
