  • Patent number: 9313491
    Abstract: A system, apparatus, method, and article to process a chroma motion vector are described. The apparatus may include a video decoder. The video decoder includes a processor to receive a compressed video bitstream. The compressed video bitstream includes a stream of pictures. The stream of pictures includes a current slice and a current block within the slice. The processor pre-computes a chroma motion vector adjustment parameter for the current slice and determines a motion vector component for the current block within the current slice using the pre-computed chroma motion vector adjustment parameter.
    Type: Grant

  • Patent number: 8068112
    Abstract: A system, apparatus, method and article to perform buffering techniques are described. The apparatus may include a buffer having a fixed number of storage slots that store reconstructed picture representations received from an image processing module. Also, the apparatus may include a buffer status unit to store a multiple information items to indicate one or more buffer characteristics of the buffer. Further, the apparatus may include a buffer control module to manage storage within the buffer.

  • Publication number: 20080101474
    Abstract: A method of decoding a slice of video data may include determining two slice reference lists that are associated with the slice of video data and finding a co-located picture that is associated with the slice of video data. The method may also include retrieving two co-located reference lists that are associated with the co-located picture. Two lowest lists for the slice of video data may be calculated by comparing pairs of the two slice reference lists and the two co-located reference lists.

  • Publication number: 20050031032
    Abstract: A method for buffer management in a video encoder is provided. When a possibility of buffer overflow is higher, a filter function is enabled in an I picture and a not coded function is enabled in a P or B picture. Furthermore, when the fullness of buffer reaches a predetermine threshold, the filter function is enabled in the I picture and a skip function is directly enabled in the P or B picture.
