Abstract
Various embodiments of the invention provide a method, system, and apparatus for transmitting screen display information from a remote server to a client. One embodiment features a video decoder that comprises (i) an input port to receive data that includes a data identifier to distinguish between a first data type and a second data type, (ii) a loss-less decoder, and (iii) a lossy decoder. The loss-less decoder is coupled to the data identifier and receives and decodes data of the first data type from the data identifier. The lossy decoder is coupled to the data identifier and receives and decodes data of the second data type from the data identifier.
