Mobile TV services are being actively developed for a variety of last hop, broadband wireless technologies. Application layer error control mechanisms such as Broadband Video Streaming seek to reduce packet loss from raw UDP transport. This paper goes further than existing streaming protocols by integrating source-coded error resilience through data-partitioning and intra-refresh macroblocks with...
This paper demonstrates a robust layered video scheme, based on data-partitioning and intended for IPTV streaming over wireless broadband. Equal error protection through rateless coding is applied, whereby higher-priority data partitioned packets are protected by appropriate selection of quantization parameter and picture slicing, so as to regulate packet size. In the mobile WiMAX channel investigated,...
Video streaming is anticipated to be a key application of broadband wireless access networks such as WiMAX. This paper proposes a combination of data-partitioning of compressed video information and rateless channel coding to ensure effective video transport. A counter-intuitive result is that comparatively improved objective video quality occurs even though privileged application-layer forward error...
This paper demonstrates that growth codes, based on Raptor channel coding, allow incremental protection of H.264 video codec data-partitioned network adaption layer units. When combined with increased protection of video reference frames, in an ADSL erasure channel up to 10 dB in video quality (PSNR) can be gained through this scheme compared to equal error protection with rateless codes. Equivalent...
