Abstract :
We consider real-time video coding and transmission over packet-switched wireless IP networks using RCPT codes in a joint source and channel coding (JSCC) approach. In particular, we study performance of this JSCC approach employing RCPT coding schemes for real-time transport protocol (RTP) H.263+ packet video transmission over slow fading Rician channels. Results indicate that an RCPT-JSCC approach is attractive for real-time video applications and leads to increased system capacity together with more acceptable delivered video quality over time-varying wireless networks.
