Chose the best wireless digital-video architecture: While most of the approaches are new to the market, their performance differs greatly

摘要

A number of wireless digital-video technologies are beginning to appear on the market. It's interesting that, at this time last year, no satisfactory architectures were available. Because of the high banddwidth required, video has been difficult to support over wireless communications. With the emergence of ultrawideband (UWB), users of digital video and other bandwidth-intensive applications can now enjoy the benefits of mobility without a fistful of cables. Several architectures based on UWB technology have emerged that use different approaches to wireless digital video. Each takes unique approaches that result in different performance, size, and cost. Some integrate directly with existing functions available on the wired system, while others may require additional components, such as CPUs, encoders, and decoders, to complete the system.
