摘要：
The invention relates to a compressor of data from data frames. According to the invention, the compressor detects “active” elements that vary from one frame to another and transmits only the “active” elements in a data block. This block also contains a state code locating this “active” data in the original frame, in order to be able to reconstitute it. The invention also relates to a data decompressor, a data block containing a data group compressed in accordance with the invention, and a bandwidth resource management method. Particular application in a satellite telecommunication system.
