Multi-rate multicast schemes can be broadly classified into two categories. In layered multicast, a video file is transmitted by a base layer, which contains the most important features of the video. Additional layers, called enhancement layers, contain data that refine the quality of the base layer. In simulcast, the video file is transmitted by replicated layers that contain the same content at...
This paper presents the performance evaluation of a multi-rate multicast protocol named adaptive smooth simulcast protocol (ASSP) for simulcast video transmission. ASSP implements a single rate TCP-friendly protocol as the underlying congestion control mechanism for each simulcast stream. ASSP is built on top of the RTP/RTCP protocol and exploits the RTCP sender and receiver reports for the dissemination...
