Abstract:
A method for compressing and transmitting data on a connection between two parties in a telecommunication system comprising at least one slow transmission channel (Um), the method comprising:assembling the data to be transmitted into frames (F) which contain at least a header section (1) and a data section (2), and compressing at least one section (1, 2) of at least some of the frames (F) prior to transmission, making at least two different compression algorithms available to the transmitting party, making at least two different decompression algorithms available to the receiving party, characterized in that the transmitting party: compresses at least one section (1, 2) of at least some of the frames (F) with at least two different compression algorithms; selects the compression algorithm that yielded the best compression ratio; and transmits the frame (F) over the slow transmission channel (Um) to the receiving party, compressed with said selected compression algorithm.
