  • Publication number: 20190052884
    Abstract: A decoder receives a bitstream containing quantized coefficients representative of blocks of video representative of a plurality of pixels and decodes the bitstream using context adaptive binary arithmetic coding. The context adaptive binary arithmetic coding decodes the current syntax element using a first mode if the current syntax element is intra-coded and if selecting between a first set of probable modes and a second set of probable modes, where the first set of probable modes are more likely than the second set of probable modes. The context adaptive binary arithmetic coding decodes the current syntax element using a second mode if the current syntax element is intra-coded and if selecting among one of the second set of probable modes.

  • Patent number: 10205948
    Abstract: Technique for initialization of encoders and decoders. In some cases, the decoder receives a slice and identifies if the slice is either a forward predicted B-slice or a backward predicted B-slice, and not both a forward and backward predicted B-slice, and based upon this identification initializes, using a P-slice technique, a context associated with the slice.

  • Patent number: 9992507
    Abstract: Methods for decoding a video bitstream. One of the methods includes receiving a respective buffer description for each of one or more decoded reference pictures from the video bitstream; wherein the respective buffer descriptions include a poc cycle parameter for one or more long term reference pictures in the one or more decoded reference pictures, and wherein the poc cycle parameter is used to calculate a picture order count (POC) for the decoded long term reference pictures; identifying one or more decoded reference pictures for a current picture from a decoded picture buffer, based on the POC for the decoded long term reference pictures; decoding the current picture using inter-frame prediction based on the identified one or more decoded reference pictures; and buffering the decoded picture in the decoded picture buffer.

  • Patent number: 9667971
    Abstract: A method for decoding video includes receiving a frame of the video that includes at least one slice and at least one tile. Each of the at least one slice and the at least one tile are not all aligned with one another. Each of the at least one slice is characterized that it is decoded independently of the other the at least one slice. Each of the at least one tile is characterized that it is a rectangular region of the frame and having coding units for the decoding arranged in a raster scan order. The at least one tile of the frame are collectively arranged in a raster scan order of the frame.

  • Patent number: 9654139
    Abstract: Provided is an electronic device configured for high throughput binarization mode. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a block of transformed and quantized coefficients (TCQs). The electronic device determines whether a high throughput binarization mode condition is met. If the condition is met, the electronic device uses the high throughput binarization mode to process the block. If the condition is not met, the electronic device does not use the high throughput binarization mode to process the block. The electronic device transmits the generated first or second bitstream to a decoder.
