  • Publication number: 20220377340
    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 the first mode if the current syntax element is intra-coded and 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 the second mode if the current syntax element is intra-coded and if selecting among one of the second set of probable modes.

  • Publication number: 20220368914
    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: 11451776
    Abstract: A method for decoding video includes receiving a frame of the video that includes at least one slice and at least one time. 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: 11431982
    Abstract: A method for decoding video includes receiving quantized coefficients representative of a block of video representative of a plurality of pixels. The quantized coefficients are dequantized based upon a function of a remainder. The dequantized coefficients are inverse transformed to determine a decoded residue.

  • Publication number: 20220046265
    Abstract: A method for tracking a reference picture on an electronic device is described. The method includes receiving a bitstream. The method also includes decoding a portion of the bitstream to produce a decoded reference picture. The method further includes tracking the decoded reference picture in a decoded picture buffer (DPB) with reduced overhead referencing. The method additionally includes decoding a picture based on the decoded reference picture.

  • Patent number: 10999579
    Abstract: A video bitstream is decoded by decoding a first syntax element with an integer value indicating a number of a plurality of entropy slices defining a first slice, a second syntax element indicating an offset, and a third syntax element indicating a slice type of the first slice. When the third syntax element indicates the slice type of the first slice is a B slice or a P slice, a flag in the slice header indicating an initialization method of a CABAC context is decoded, and the CABAC context is initialized using one of the first initialization method and the second initialization method. When the third syntax element indicates the slice type of the first slice is an I slice, the CABAC context is initialized using a third initialization method.
