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).
