White Papers

Grass Valley technologies are easy to understand with a variety of white papers that we produce on specific products or specific applications available within those products.

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.

Ethernet Technology Trends White Paper

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.

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.

The Spring of the IP Technology Transition for Broadcast Television Production White Paper

We all know that Ethernet and IP underpin the Internet and form one of the most disruptive technologies in the history of mankind. Insatiable consumer demand for content continues to fuel the development of ever faster networks like hydrogen fusion fuels the sun. As it stands today, the bandwidth required for data networking equals — and in many cases exceeds — the bandwidth requirements for full bandwidth, real-time video.

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.

LDX Series Cameras with Xensium-FT Imagers: A Superior Replacement for CCD Technology White Paper

While CCD technology was the best choice for imagers in broadcast applications for many years, the latest generation of CMOS imagers now offers a range of advantages over CCD. This includes better sensitivity in progressive video modes today, and the potential for higher resolution, extended dynamic range and higher frame rates in the future. CMOS is setting the new standard for high-end broadcast applications.

Taking Control of Replay White Paper

Live event production requires a sophisticated replay system that can fully leverage today's file-based infrastructures to deliver more than just "record and play." Replay systems should take full advantage of IT-centric open systems, being able to run on stand-alone servers or complex SAN systems with advanced metadata capabilities, while also being easy to use by operators.

The Benefits of HQX White Paper

This paper discusses the Intermediate Codec solutions available from several vendors which are then compared in terms of picture quality, flexibility and suitability for use with graphics as well as video. In like-for-like tests, the Grass Valley, a Belden Brand, HQX Intermediate Codec offers comparable picture quality and is shown to have superior multigenerational performance. When combined with frame rate and resolution flexibility, plus built-in alpha channel support, this paper supports the conclusion that HQX is the best choice for creative editing.

Comparing Single-Speed and Dual-Speed Acquisition for Slow-Motion Replays Versus Triple-Speed Super Slow-Motion

Triple-speed super slow-motion acquisition delivers a completely different level of performance for slow-motion replays when compared to single-speed and dual-speed acquisition. The various approaches address different production requirements, and in many cases a combination of them are used during the same production. This document looks at the differences between the different types of slowmotion acquisition methods.
