Wireless Video Executive Summary
New technologies have greatly expanded the number of choices available to broadcasters for transporting live video from venues to studios. For example, cell-phone circuit bonding has now made it possible to transmit live video from anywhere that has good cellular coverage. Recent advances in Wi-Fi standards have increased the bit-rates available for transporting video in local areas. Today, even uncompressed HD video can now be transported wirelessly using 1.5 Gigabit radio links operating at 60 GHz. Each technology has bene fits and drawbacks, relative to specific applications and user environments.
Selecting the right wireless technology for each application requires analyzing the cost, bandwidth and reliability of a variety of potential approaches. As a vendor that o ffers a wide range of different wireless video products, VidOvation is uniquely positioned to provide information about the pros and cons of each different solution. In this whitepaper, we hope to provide clear, useful information to support fair comparisons between the various devices that are available on the market. Our goal is to help you choose the right technology for every network, thereby earning your trust and your business.
Wireless Video Introduction
Wireless video transport has been a key part of television broadcasting since the first over-the-air transmission tests were performed almost a century ago. The methods used to transport video signals from one location to another have continued to push the limits of each new technology that has come along, including coaxial cable, microwave, satellite, fiber optics and cellular radios. With high bandwidth signals, demanding QoS (Quality of Service) requirements and sensitivity to excessive delay, video has often been at the leading (or bleeding) edge of the capabilities of many technologies.
Building on these past successes, television broadcasters today have an enormous range of wireless video transport options. These range from dedicated links that support 1.5 Gbps uncompressed HD video to highly compressed video streams that run over Wi-Fi infrastructure. In between are devices and systems to fit virtually every application. With so many choices, it can be difficult to select a suitable product that offers the best combination of performance and reliability at a price point that makes sense for each project.
VidOvation wireless video solutions was founded to offer a wide selection of video transport solutions, including many wireless products. With the perspective gained from this range of offerings, it becomes easy to objectively analyze the relative merits of different technologies. Each one has specific features that may make it suitable for use in particular set of applications but not in others. Because of the overall complexity of comparing such a wide range of technologies, the following discussion will be divided into four major sections. First, a number of criteria that can be used for selecting and comparing various solutions will be defined. This will be followed by a discussion of a few key applications that are particularly common for wireless video links. Then, the actual technologies will be analyzed, based on their potential applications and various selection criteria. Finally, some of the key data will be summarized in a comparison table.
