A video transmission system that achieves uninterrupted video transmission, even when there are large bit rate fluctuation due to receiving terminal movement and so forth, in a network such as a wireless network in which transmission bit rate fluctuations occur. In this system, when a video receiving apparatus (receiving terminal) 150 is moving, a video transmitting apparatus (transmitting terminal) 100 lowers the base layer bit rate of layered-coded data to the limit. When the base layer bit rate is lowered in this way, the bit rate of the lowest enhancement layer is raised and effects on the received image quality of other terminals due to lowering of the base layer are suppressed, or the lowest enhancement layer is divided finely and the adjustability to a bit rate under bit rate fluctuations is improved.
