  • Reference data buffer for intra-prediction of digital video
    Patent number: 8320463
    Abstract: Encoding or decoding digital video frames in intra-prediction mode by selecting column reference data locations for blocks adjacent a current block from a column reference data buffer storing column reference data samples for no more than two macro blocks of the frame. In some cases, the column reference data buffer may include a storage size for samples of a first column of data of blocks of one macro block of luminance samples. Encoding and decoding may also include selecting row reference data locations for blocks adjacent a current block from a row reference data buffer storing row reference data samples for at least one row of macro blocks of the frame. In some cases, the row reference data buffer may include storage for samples of a first row of data of fourteen successive blocks spanning two rows. The concept can be applied to various video processing components and standards.

    Abstract: A decoding method and a decoding apparatus is provided. The decoding apparatus includes a control unit, a lookup unit, an arithmetic unit, a first switch and a second switch. The control unit receives a part of a bin string. The lookup unit finds out a flag, a length and an indicator, corresponding to the part of the bin string, from a lookup table according to the part of the bin string and a node, and judges whether the flag is equal to a predetermined value. The arithmetic unit finds out a syntax element symbol corresponding to the bin string according to a basic syntax element symbol. The first switch connects the control unit to the lookup unit or the arithmetic unit. The second switch outputs the indicator as the basic syntax element symbol to the arithmetic unit or feeds the indicator as a next node back to the lookup unit.
