  • Publication number: 20150338901
    Abstract: Systems and methods for providing power to a home entertainment integrated circuit chip are disclosed. The home entertainment integrated circuit chip can operate in at least two power control modes: “power on” mode and “standby” mode. In power on mode, power is supplied to IC core module from a main power supply. The power supplied to the IC core module is isolated from power supplied to a standby island. Accordingly, during the second mode power is applied only to the standby power island through a regulator internal to the integrated circuit chip. The regulator is coupled to an external peripheral input/output (I/O) power supply that is independent of the main power supply.

  • Patent number: 9154791
    Abstract: A low complexity method for directly decoding low-resolution video frames from compressed high-resolution video content that were encoded using predictive coding toques, such as the H264 video coding standard, is disclosed. The decoding resolution is inversely proportional to the decoding complexity. Thus, a smaller decoding resolution yields higher computation and power savings. Low-frequency coefficients of 2 Dimensional transformed predictions are added to low-frequency coefficients of a transformed residual error. Low-frequency coefficients of the reconstructed data are then inversely transformed, having a smaller size transform. Further computational and power savings are obtained by reconstructing only those referenced pixels necessary for accurate decoding of proceeding Intra blocks.

  • Publication number: 20150146785
    Abstract: A method, system and computer program for decompressing video data, storing the compressed video data in such a way that random access is possible and the data can be mapped efficiently into existing memory systems and interface protocols. The compression is accomplished via lossless compression using an algorithm optimized for video data. Due to the compressed format, data transmission consumes less bandwidth than using uncompressed data and prevents degradation in the decoded video.
