The present invention relates to scheduling, compression and transcoding of data content for mobile terminals with limited resources, and provides a method of transferring information or content to or from a terminal dependent on a number of its parameters such as its battery level, processing resource status and memory resource status, and the link conditions. Thus for example a terminal with plenty of processor resources but a single narrowband wireless link may implement a high compression ratio in order to improve the file transfer time to the terminal, even if this requires a high de-compression processing overhead. Such a set-up may be changed during a connection session, for example if the battery runs low necessitating reduced processing. In preferred embodiments this method of transferring content is implemented using a programmable or dynamically adaptable proxy device which adjusts the transcoding and/or compression, as well as its scheduling or rate and timing of transfer of the transcoded/compressed information to and from the terminal over one or more network connections. |
