    摘要: A multimedia data system comprising a synchronization unit. The synchronization unit receives a demodulated bitstream, checks whether a FAW pattern corresponding to a candidate of the bitstream exists, checks whether an additional information corresponding to the candidate of the bitstream is valid when the FAW pattern exists, determines a hit weighting corresponding to the candidate according to the checking result, determines whether the hit weighting meets a criterion and outputs a synchronization signal when the hit weighting meets the criterion.

    摘要: Methods for removing redundancies in a video stream based on efficient pre-transmission detection of static portions of the video stream. In one embodiment supporting wireless transmission of a video stream having a series of video frames, a mathematical operation (such as a hash function, summing operation or CRC) is performed on (1) a (reconstructed) data block(s) of a video frame in order to generate a first check value and (2) a co-located data block(s) of a second, sequential video frame in order to generate a second check value. The first and second check values are compared to detect static video content in the video stream. When static video content in a video stream is detected, the static nature of the content is indicated in the compressed bit stream and the amount of wirelessly transmitted data corresponding to the static portions of the video stream may be reduced.

    摘要: The present invention relates to a device able to receive packets circulating in a packet-switching network. The packets include information on a synchronization signal. The device is configured for producing first and second pulses synchronous with the synchronization signal. The first and second pulses have different periods, which are integer value multiples of the synchronization signal period.
