  • Patent number: 10012691
    Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of testing a system-on-chip (SoC). The method includes generating data for a plurality of audio channels. The data comprises first data corresponding to a first audio channel and second data corresponding to a second audio channel. The method further includes outputting the first audio channel over a first output port of the SoC for output by a speaker. The method further includes outputting the second audio channel over a second output port. The method further includes looping back the second audio channel from the second output port to a first input port of the SoC as third data. The method further includes comparing the third data to the second data. The method further includes determining if the SoC is operating correctly based on the comparison of the third data to the second data.

  • Publication number: 20150156498
    Abstract: In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

  • Publication number: 20060268841
    Abstract: A method and apparatus to improve error resiliency in processing a multimedia bitstream is described. A directory of header information is generated for a multimedia bitstream. The directory information comprises packet header information associated with the multimedia bitstream. The directory information may be transmitted to a receiver along with the multimedia bitstream. A receiver of the multimedia bitstream and the directory can utilize the header information to identify and locate packets within and subsequent to erroneous data in the received bitstream. By identifying and locating packets that may otherwise be discarded, the receiver may be able to improve error recovery and decoding of the multimedia data.
