Abstract: Video transmission over networks is getting increasingly impor-tant, thus upcoming network types like Mobile Ad-Hoc Networks (MANETs) can also become a suitable platform for exchang-ing/sharing real-time video streams. We present an approach using different sources with linear independent representations of a lay-ered video stream for increasing the robustness in transmission. This approach is based on the Scalable Video Coding (SVC) Ex-tensions of H.264/MPEG-4 AVC with different layers for assign-ing importance for transmission. Additionally a novel Unequal Packet Loss Protection (UPLP) scheme based on Raptor forward error correction codes is employed. This scheme allows for recep-tion from different sources and benefits from it. While the recep-tion of a single stream guarantees base quality at least, the com-bined reception enables play-back of video of full quality and/or lower error rates.
