The article examines several wireless digital video applications across various market segments and compares the various technologies and their applicability to those applications. Wireless digital video technology addresses the needs of personal computer (PC) applications, consumer electronics and home entertainment applications, and mobile applications. As the most challenging area for wireless digital video, PC segment demands high-quality wireless display of movies and the ability to handle the challenges of graphics and text introduce. To wirelessly distribute digital video, vendors are using the high compression approach that employs motion picture experts group or motion joint photographic experts group and the more optimized approach base on the WiMedia common radio platform.
