Method and modules for transmitting and receiving compressed data

摘要

The present invention relates to a method for transmitting digital audio and/or video data. The invention furthermore relates to a first and a second communication device and a first and a second program module therefor. The method comprises the steps of: Dividing of digital audio and/or video data (S1, S2) of a first data stream (IDS) into first frames (F1-F5). Frame-based encoding of the first frames (F1-F5) into second frames (V1P-V3P; V1-V20 containing compressed data of the first data stream (IDS). Generating a flow of messages of a real time protocol, a majority of the messages containing at least one first frame (V1) of the second frames and a state information (SI1) needed to decode the first frame (V1). The state information (SI1) is derivable from a second frame (V1P-V3P) provided that it is available. The second frame (V1P-V3P) precedes the first frame (V1) and is contained in a message preceding the message containing the first frame (V1) to be decoded. Transmitting the messages from a first (CD; T11; S21; ACC) to a second communication device (CD; T31; T12). Decoding the second frames (V1P-V3P; V1-V20), thereby evaluating the respective state information (SI1) contained in a respective message to decompress the respective first frame (V1) being contained in the respective message (M1).
