  • Publication number: 20190268622
    Abstract: An encoder encodes pixels representative of a picture in a multimedia stream, generates a first approximate signature based on approximate values of pixels in a reconstructed copy of the picture, and transmits the encoded pixels and the first approximate signature. A decoder receives a first packet including the encoded pixels and the first approximate signature, decodes the encoded pixels, and transmits a first signal in response to comparing the first approximate signature and a second approximate signature generated based on approximate values of the decoded pixels. If a corrupted packet is detected, the multimedia application requests an intra-coded picture in response to the first approximate signature differing from the second approximate signature. The second signal instructs the decoder to bypass requesting an intra-coded picture and to continue decoding received packets in response to the first approximate signature being equal to the second approximate signature.

  • Publication number: 20190158836
    Abstract: An encoder of a multimedia system encodes data representative of each image in a video stream to form a bitstream that is transmitted over a network to a decoder that decodes the bitstream and provides the decoded information to a multimedia application for display to the user. As consecutive images may have nearly identical pixel values, the multimedia system detects pixel value variations between consecutive images that are below a specified threshold to reduce active processing on such pictures, which includes, for example, encoding, decoding, and post-processing. The multimedia system either selectively encodes or selectively processes the current image that has pixel values that vary from an immediately preceding image within the specified threshold.

  • Publication number: 20170293564
    Abstract: Systems, apparatuses and methods of adaptively controlling a cache operating voltage are provided that comprise receiving indications of a plurality of cache usage amounts. Each cache usage amount corresponds to an amount of data to be accessed in a cache by one of a plurality of portions of a data processing application. The plurality of cache usage amounts are determining based on the received indications of the plurality of cache usage amounts. A voltage level applied to the cache is adaptively controlled based on one or more of the plurality of determined cache usage amounts. Memory access to the cache is controlled to be directed to a non-failing portion of the cache at the applied voltage level.
