Loss reporting for packet-switched streaming services using loss RLE report blocks

摘要

The present invention relates to a method, communication terminal, a streaming server and a communication system for providing feedback for data packets of a streaming session from a client to a streaming server to enable a target number of retransmissions for each data packet within a client buffering time defining a time interval during which a data packet is stored in a buffer at the client before being processed. The at least one streaming session is provided using a RTP protocol and the RTCP protocol, wherein a fraction of the available bandwidth is allocated to RTCP packets. To specify method how compressible and detailed report blocks may be tailored to different streaming client and server implementations the present invention gradually reduces the data included in a RLE Report Block based on different mechanisms to fulfill the RTCP bandwidth constraint and to enable a target number of retransmissions for each RTP packet.
