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 ). A video receiving apparatus ( 150 ) determines reception channels by means of a reception channel determination section ( 158 ) using input priority quality and a received group list, and receives the determined channels by means of a video receiving section ( 160 ).
