  • Patent number: 8175325
    Abstract: Watermark information (denoted WM) consists of several symbols which are embedded continuously by reference sequence modulation in an audio or a video signal. At decoder site the WM is regained using correlation of the received signal with a corresponding reference sequence. The symbols form watermark data frames. The invention uses for the bit values ‘zero’ and ‘one’ in each payload symbol and for each payload symbol in a watermark data frame different reference sequences, without using synchronisation symbols. A logarithmic search is performed in the WM decoder to reduce the numbers of correlations to be calculated. The invention makes watermarking of critical sound signals much more robust.

  • Patent number: 7594253
    Abstract: A digital television autoprogramming and tuning method and apparatus. In a digital television which can tune both MPEG 2 and PSIP format signals, a method of tuning uses one or more tables of information populated during an autoprogramming process. For MPEG 2 channels, the physical channel equals the major channel number and can be directly tuned. For PSIP channels, the major channel indexes a TSID which is used to determine a physical channel. If the TSID does not correspond to the correct program, the correct TSID is determined from the Program Specific Information in the data transport stream 134 and the system re-tunes to the correct physical channel. The autoprogramming process sequentially steps through each physical channel and populates the autoprogramming tables with information about each channel it finds, saving only a single TSID for a given major PSIP channel.

  • Patent number: 7082221
    Abstract: In an encoding process, video data are represented as a bitstream of quantized base data and enhancement data, which capture the difference between a quantized base video picture and an original unquantized input video picture. Due to bandwidth constraints on a communication channel, it may be unfeasible to transmit all enhancement data. During the encoding process, the enhancement data may be divided into “layers” based upon bandwidth restrictions. Following transmission, the layers are recombined and are added to the base data by a decoder, producing a viewable video sequence.

  • Patent number: 6845107
    Abstract: The present invention makes it possible to efficiently transmit data for statistical multiplexing which is required for control using statistical multiplexing. By utilizing private packets, respective encoding devices transmit encoding difficulties serving as the data for statistical multiplexing to a multiplexer (4) via the same transmission channels as encoded video data and audio data are transmitted. The multiplexer (4) conducts multiplexing processing on data supplied from the respective encoding devices at a first rate R1 larger than a transmission rate on a transmission channel of a subsequent stage, and outputs a transport stream (TSd including the private packets to a statistical multiplexing computer.

  • Publication number: 20040252229
    Abstract: An approach is provided for supporting carrier synchronization in a digital broadcast and interactive system. A carrier synchronization module receives one or more signals representing a frame that includes one or more overhead fields (e.g., preamble and optional pilot blocks and one or multiple segments separated by pilot blocks). The module estimates carrier frequency and phase on a segment by segment basis and tracks frequency between segments. Carrier phase of the signal is estimated based upon the overhead field. Estimates carrier phase of random data field are determined based upon the estimated phase values from the overhead fields, and upon both the past and future data signals. Further, the frequency of the signal is estimated based upon the overhead fields and/or the random data field. The above arrangement is particularly suited to a digital satellite broadcast and interactive system.

  • Patent number: 6825874
    Abstract: A system enables the user to monitor a number of channels to determine the degree of action occurring on each of those channels which are not currently tuned for reception. The system may develop a count of the number of packets received over a given period of time for a plurality of channels selected by the user and may advise the user when those channels exceed a preset level. Thus, the user may be advised when the action level on another channel exceeds a desired level allowing the user to tune to that channel if desired.
