Abstract: Preferred embodiments of the present invention are directed to a system, method and apparatus for adaptively compressing and decompressing regions of an image depending on the properties of the uncompressed data regions. Preferred embodiments of the compression and decompression process of the present invention comprise a compression process and a decompression process, wherein the compression process comprises segmenting an image into a plurality of segments, analyzing each segment to determine an optimal compression technique, and compressing the segment in accordance with the chosen compression technique. After the optimal compression is applied to the segment, the segment is stored in computer memory and the compression process increments to the next segment of the image frame. Once the image stream has been processed, temporal compression is performed and the compressed image stream is stored for later use.

Abstract: A method for carrying out a transaction between a client and a server in an electronic marketplace hosted by the server is provided. Data from a server is provided to a client sufficient to enable the client to operate a client-based shopping cart in an electronic marketplace hosted by the server. The client-based shopping cart is activated, and an item is added to the client-based shopping cart. Information necessary to complete a transaction for the item is calculated using the client-based shopping cart. A transaction for the item is then submitted to the server together with the calculated information, and the transaction is processed using the server.
