The recently published extension of the H.264/AVC video coding standard introduces scalability features by employing a layered encoding of the video stream. In our work we investigated the usage of this scalable extension of H.264/AVC for in-network multimedia adaptation. We developed an RTSP/RTP-based proxy which exploits the layered encoding of the video and can perform real-time video adaptation on an inexpensive off-the-shelf WiFi router. This is achieved by applying a stateful, packet-based adaptation approach that keeps the computational costs at a minimum. With that approach it is possible to simultaneously adapt multiple video streams to varying network conditions or to the capabilities of the consumers' end-devices. In our demonstration we show the streaming of two scalable video streams from a server to a client and the in-network adaptation of the video at the WiFi router. The adaptation can be controlled interactively in the temporal, spatial and SNR domains.}, doi = {10.1109/CCNC.2009.4785005}, isbn13 = {9781424423088}, language = {EN}, location = {Las Vegas, NV, USA}, pdf = {https://www.itec.aau.at/bib/files/CCNC09_SVC_Adaptation_Router_preprint.pdf}, talkdate = {2009.01.11}, talktype = {poster} }
