  • Patent number: 10015521
    Abstract: Errors in a double-ended motion estimation system are detected. An image space is divided into blocks, and a motion vector is derived for each block. The space is also divided into indication blocks. Each motion vector is used to identify one or more indication blocks, in which a value is modified. In an example, a backward component of the motion vector is used to project a source flag into one indication block, and a forward component of the motion vector is used to project a destination flag into another indication block. After processing each motion vector, an indication block with no flags set is indicative of pixel data that has not been tracked, and therefore indicative of a motion estimation error. Remedial action may then be taken.

  • Patent number: 9877033
    Abstract: This disclosure describes techniques in which the decoding order of video blocks is modified relative to the display order of video blocks. The decoding order may be modified temporally such that video blocks of different video frames (or other coded units) are decoded in an alternating manner. In this case, the decoding order of video blocks may alternate between video blocks of two or more different frames. Furthermore, the decoding order may also be modified spatially within a given video block such that the video blocks are decoded in an order that does not correspond to the raster scan order of the video blocks. The techniques may improve the use of memory by improving the likelihood of cache hits, thereby reducing the number of memory loads from an external memory to an internal cache associated with the decoder.

  • Patent number: 9001275
    Abstract: HDMI is a digital audio and video communications protocol commonly used in consumer electronics. HDMI is particularly synonymous with high fidelity audio and video. Even though HDMI is a digital communications protocol, the audio quality can be impaired by analog signal impairments and distortions even if there are no digital decoding errors. In particular, the very process by which the audio is converted from Digital (HDMI) to human audible “Analog Audio” can be prone to errors. This occurs when the Digital to Analog Converter (DAC) clock, which is derived from the HDMI TMDS clock or HDMI source, is “distorted” due to its jitter, resulting in erroneous sampling or outputting of vital audio samples, thereby reducing the audio quality of the experience. The present invention reduces the jitter on the TMDS clock, and hence the audio DAC clock, resulting in lower audio distortion.

  • Patent number: 8928804
    Abstract: Disclosed are various embodiments directed to transcoding a bit stream in parallel. A bit stream may be divided into a plurality of segments, where a plurality of transcoders encode at least a portion of the segments in parallel. If encoding is performed using variable bit rate (BR) encoding, each encoder may encode a segment and vary a BR for the segment. A measured average BR is compared with a target average BR to determine whether to adjust a video quality level (VQL) or any other encoder parameter. A relatively constant subjective quality may be maintained using variable BR encoding while achieving a target average BR. When using constant BR encoding, a VQL or other encoder parameter is used by encoders to achieve relatively constant subjective quality. For example, a relatively continuous quantization parameter between adjacent encoded segments may be achieved.
