In order to deal with changing transmission characteristics like varying link bit-rate or handover, adaptive streaming features like client feedback have been included into Release 6 of 3GPP PSS. The adaptive behavior of the(More)
A new transmission rate control for wireless multimedia streaming is introduced using RTCP feedback about the status of the streaming client buffer. Here, extended RCTP feedback is used as described within the 3GPP PSS streaming standard. Compared with algorithms from the literature buffer overflows are always avoided and higher buffer utilization is(More)
