Abstract	In this work we present a video transmission system for packet lossy channels based on the progressive texture video coding (PTVC) algorithm. A posteriori video rate control on the progressively coded messages is simplified significantly as for rate adaptation only the later part of this message can be truncated. This property is used by an appropriate unequal erasure protection (UXP) scheme which allows us - in combination with the progressively coded messages - to transmit very efficiently over packet erasure channels like the Internet. An appropriate rate allocation scheme based on dynamic programming is introduced. Additionally, a source-channel coding system exploiting network feedback is presented. Dependency on feedback delay is studied. Information between source encoder, channel encoder and network is exchanged and exploited in a cooperative way. The investigated systems show significant gains for different video sequences and different channel erasure rates when compared to sophisticated standard approaches.
