  • Publication number: 20070166000
    Abstract: Disclosed are systems and methods for creating a trick mode stream. A digital home communication terminal (DHCT) comprises a network interface, a storage medium, at least one memory storing program code; and at least one processor programmed by at least the program code. The network interface is in communication with a second DHCT. The program code enables the DHCT to: select a first encoded picture frame from a recorded video stream on the storage medium; retrieve a first sequence of transport packets encapsulating the first picture frame; create a first transport packet containing a first client control packet associated with the first picture frame; and transmit, to a video decoder in the second DHCT, a trick mode stream comprising the first transport packet followed by the first sequence of transport packets. The first client control packet comprises the size of the first picture frame and a decoder command.

  • Patent number: 6466220
    Abstract: A method and apparatus for display of graphical data is described. The invention provides an architecture for graphics processing. The architecture includes pipelined processing and support for multi-regional graphics. In one embodiment, a graphics driver according to the invention can receive multiple independent streams of graphical data that can be in different graphical formats. The independent streams are synchronized and converted to a common format prior to being processed. In one embodiment, multi-regional graphics are supported with off-screen and on-screen memory regions for processing. The regions of the multi-regional graphic are rendered in an off-screen memory. The data in the off-screen memory are converted to a common format and copied to on-screen memory. The data in the on-screen memory is used to generate an output image. Alpha blending can also be programmed to provide multi-regional graphics or other graphical features.
