Abstract : We present a streaming system that utilizes interleaved transmission for real-time H.264/AVC video in 3G wire-less environments with benefits shown especially in the presence of link outages. In the 3GPP Packet-switched Streaming Service Rel. 6, H.264/AVC and its RTP pay-load format are specified. The RTP payload format al-lows interleaved transmission of NAL units of H.264/AVC. Our simulations also include audio into the interleaving framework and are conducted within a test-bed that emulates a 3G network including block error rates on the physical layer, a buffer for retransmission on the link layer for different error rates, and link out-ages. The experimental results demonstrate the superior performance of interleaving for typical link outage set-tings.
