Abstract: A system, method and apparatus for implementing a wireless point-to-point interface that securely and robustly delivers digital content from a generalized content source to a generalized content sink. The system, method and apparatus performs in a manner that is sufficiently secure and robust to serve as a replacement for the delivery of HDMI content over cable. The system, method and apparatus is also applicable to the delivery of other types of content traditionally delivered over cable, including but not limited to Digital Video Interface (DVI) content, composite video (CVSB) content, S-video content, RGB video content, YUV video content, and/or various types of audio content.

Abstract: A video transmission system, a video transmitting apparatus, a video receiving apparatus, and a video transmission method whereby, when a plurality of terminals whose characteristics differ receive video simultaneously, each terminal can receive video with quality appropriate for that terminal. In this system, a video transmitting apparatus (100) divides layered-coded data by quality and bit rate by means of a channel division section (106), and transmits data on separate channels from a video transmitting section (108) after adding priorities calculated by a priority calculation section (112). Video transmitting apparatus (100) also groups channels by quality and calculates a group list by means of a group list calculation section (114), and transmits this group list from a group list transmitting section (116).
