ABSTRACT:
A method, system and product are provided for direct rendering of video images to a compressed video data stream. The method includes generating encoded video data directly from an electronic graphic system, the encoded video data representing a full frame image, and generating update encoded video data directly from the electronic graphic system, the update encoded video data representing changes in the full frame image. The method also includes generating movement vector encoded video data directly from the electronic graphic system, the movement vector encoded video data representing movement in the full frame image, and decoding the encoded video data, the update encoded video data, and the movement vector encoded video data for playback at a destination. The system includes control logic for performing the method. The product includes a storage medium having computer readable programmed instructions recorded thereon for performing the method.
