摘要： The invention is related with the problem of utilizing data compression in a network of distributed stations. Often header compression is used to improve the bandwidth usage in networks, in particular wireless networks. Header compression could be implemented in access points or routers, but both implementations have serious problems, e.g. due to limited CPU power, lack of scalability, or handover latency. To resolve the problems the invention proposes to use a dedicated data compression server in the network and a new protocol to transparently deploy data compression in the network.

摘要： A method and apparatus for digitally encoding video image data, which is particularly suited for encoding Internet Web pages, eliminates the need for performing time consuming, computationally intensive motion vector searches by taking advantage of prior knowledge regarding the Web page movement. In a first preferred embodiment, a digital video encoder, such as an MPEG encoder, employs Web page scrolling coordinates obtained from a browser application to determine, through calculation instead of searching, motion estimation for all the macroblocks of the present image frame relative to the previous frame. In a second preferred embodiment, the encoder receives information from the browser application that indicates that certain portions of an image, such as a Web page animation window, are continuously changing, and thus should be encoded as an intra frame. The invention may be employed in a cable television system which includes Internet access capabilities that permit system users to download Web pages for viewing on their televisions from a remote browser application located in the cable system's headend.
