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.

Abstract: Methods and systems are disclosed for managing performance states of a data fabric of a system on chip (SoC). Techniques disclosed include determining a performance state of the data fabric based on data fabric bandwidth utilizations of respective components of the SoC. A metric, characteristic of a workload centric to cores of the SoC, is derived from hardware counters, and, based on the metric, it is determined whether to alter the performance state.

Abstract: Systems, apparatuses, and methods for encoding bitstreams of uniquely rendered video frames with variable frame rates are disclosed. A rendering unit and an encoder in a server are coupled via a network to a client with a decoder. The rendering unit dynamically adjusts the frame rate of uniquely rendered frames. Depending on the operating mode, the rendering unit conveys a constant frame rate to the encoder by repeating some frames or the rendering unit conveys a variable frame rate to the encoder by conveying only uniquely rendered frames to the encoder. Depending on the operating mode, the encoder conveys a constant frame rate bitstream to the decoder by encoding repeated frames as skip frames, or the encoder conveys a variable frame rate bitstream to the decoder by dropping repeated frames from the bitstream.

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.
