  • Patent number: 7860327
    Abstract: Additional data compression is achieved by enhancing the spatial and temporal correlation of the data in a pre-processing module prior to sending the data to an encoding algorithm, such as for example, the MPEG algorithm. An input frame of data is decomposed into a luminance frame and two chrominance frames. The luminance frame is transformed on the basis of each of a plurality of luminance pixels within the frame to produce a transformed luminance frame having a plurality of transformed luminance pixels. A map describing a relationship between the plurality of luminance pixels of the luminance frame and the plurality of transformed luminance pixels of the transformed luminance frame is created. The two chrominance frames are transformed according to the map to produce two transformed chrominance frames. The transformed luminance frame and the two transformed chrominance frames are integrated to produce a transformed output frame.

  • Patent number: 7154554
    Abstract: An apparatus comprising a plurality of columns bound together, configured to display a single row of pixels scanned out from top to bottom. It also comprises a timing control unit to synchronize between the columns to allow all pixels of a single row to be lit at the same time.

  • Patent number: 6847780
    Abstract: A method and system respond to a user request for trick-mode play. A decoding device conveys the request to a device for storing a video stream. A current point location in the memory is frozen and the pointer is set back by a preselected back track distance. Then a search for a first target header is begun. The target header is either a sequence or GOP (group of pictures) header. When a target header is found, a data segment is selected which includes the target header. This is the start of the trick-mode stream. Further target headers are sought and further data accessed until a full trick-mode stream has been generated.

  • Publication number: 20040194134
    Abstract: Disclosed is a method for changing channels in a digital television transport stream, which comprises accessing the digital television transport stream, itself comprising a plurality of multiplexed channels, by using a first tuner, displaying a first program channel from the digital television transport stream, detecting and storing in a buffer memory recent video data from a second channel while displaying the first channel by using a second tuner, immediately recalling and presenting a complete video frame from the stored video data of the second channel for display when the second channel is selected by the user, and displaying real-time video from the second channel when decodable real-time video data is available from the transport stream.

  • Publication number: 20040181813
    Abstract: Methods for providing fast channel change in a digital display system. Spare tuners can be provided for predicting a next channel that may be viewed. These spare tuners may be used to capture information that is used to provide a fast channel change to an accurately predicted next channel. A spare tuner may be a PIP tuner. A three tuner system can be used where multiple tuners are applied to multiple predicted channels. Also, a spare tuner can be used to scan available channels and cache information on a set of channels to provide a fast channel change to a cached channel. The information cached can include program information, e.g., table information. Spare decoders (e.g., virtual decoder) can also be used to predict a next channel and provide fast channel change thereto.
