Embodiment Construction
[0027] The invention provides a method for compressing headers, a compressor and a transmission system, which can effectively compress the protocol headers of DVB-H.
[0028] The specific implementation of the header compression method provided by the present invention will be described in detail below.
[0029] The IP datagram after multi-protocol encapsulation, its header part includes: MPE data segment header, IP header, UDP header, RTP header, there are a large number of redundant fields in the header, especially between the consecutive data segment headers, The embodiment of the header compression method provided by the present invention is realized by compressing these redundant fields.
[0030] Taking the Multi-Protocol Encapsulation-Forward Error Correction (MPE-FEC) frame in the DVB-H standard as an example, redundant fields that can be compressed in the IP datagram header are described in detail. According to the DVB-H standard, each MPE-FEC frame is divided into an...
