摘要： In a multimedia streaming network where a client has a receiver buffer to store a plurality of packets received from a server so as to compensate for the difference between data transmission amount by the server and data usage amount by the client, the server should be able to adapt the data transmission rate based on the status of the receiver buffer. For rate adaptation purposes, server reconstructs a list of packets in the receiver buffer based on information provided by the client. The information signaled to the server is indicative of the next packet to be decoded in the client. The information can be the sequence number of the next packet to be decoded, the DON number of the next NAL unit to be decoded, or the sequence number of the packet carrying the next NAL unit to be decoded and the DON indicative of the decoding order of that next NAL unit.

摘要： The invention discloses a method of improving the playback of streamed media on a client device by overcoming problems caused by variations in the transmission delay of packets due to network and transport protocol operation and variations in encoding/server specific delays. In an embodiment of the invention, a client device has a decoder (120) and a predecoder buffer (110) which receives streamed packets from source server via a packet network. The pre-decoder buffer is variable in size and has a variable initial buffering time for receiving the transmitted packets from the source server prior to decoding in the decoder. The initial buffering time and pre-decoder buffer size can be dynamically adapted for improved playback performance by the source server. In a further aspect of the invention, a post-decoder buffer operates in conjunction with the pre-encoder buffer to reduce decoding-related delay variations.

摘要： A system and method provide for updating a parameter set in streaming applications. The method includes receiving a first parameter set from a server device at a client device, receiving an updated parameter set having synchronization information at the client device, wherein the updated parameter set is sent from the server device using a Real Time Streaming Protocol (RTSP) method or Session Description Protocol, processing a bitstream received from the server device at the client device using the first parameter set, and processing the bitstream at the client device using the updated parameter set when the synchronization information indicates that the updated parameter set should be used. The synchronization information may include, but is not limited to, a real-time transport protocol timestamp, a normal play time timestamp, network abstraction layer unit time, and a decoding order number. The RTSP method may include, but is not limited to, a SET_PARAMETER method, a GET_PARAMETER method, a PAUSE method, a PLAY method, a OPTIONS method, a DESCRIBE method and a PING method.

摘要： The use of a picture delimiter that is contained in a NAL unit type value that is reserved in the current AVC or SVC specification. The present invention provides the scalability information for the H.264/AVC base layer in such a manner that bitstreams remain decodable with H.264/AVC decoders. In addition, the picture delimiter of the present invention may contain many other syntax elements that can help in easier processing of bitstreams compared to the plain H.264/AVC bitstream syntax.
