  • Patent number: 7203238
    Abstract: In one embodiment, a 3:2 pull-down detection component of a video encoder uses motion vectors to determine whether a repeated field exists in a video sequence. The 3:2 pull-down detection component uses field motion vectors determined by a motion estimator and compares the field motion vectors to a threshold to determine whether a repeated field exists. If a repeated field exists, a video encoder can then eliminate the repeated field.

  • Patent number: 6934335
    Abstract: In one embodiment, a video encoder having a first and second phase of motion estimation, and scene change and 3:2 pull-down detection components is provided. In another embodiment, the first phase of motion estimation determines a set of field motion vectors to execute the scene change and 3:2 pull-down detection components. In another embodiment, the scene change and 3:2 pull-down detection component, and the second phase of the motion estimation occur after the first phase of motion estimation.

  • Patent number: 6507614
    Abstract: An efficient digital video (DV) decoder process that utilizes a specially constructed quantization matrix allowing an inverse quantization subprocess to perform parallel computations, e.g., using SIMD processing, to efficiently produce a matrix of DCT coefficients. The present invention utilizes a first look-up table (for 8×8 DCT) which produces a 15-valued quantization scale based on class number information and a QNO number for an 8×8 data block (“data matrix”) from an input encoded digital bit stream to be decoded. The 8×8 data block is produced from a deframing and variable length decoding subprocess. An individual 8-valued segment of the 15-value output array is multiplied by an individual 8-valued segment, e.g., “a row,” of the 8×8 data matrix to produce an individual row of the 8×8 matrix of DCT coefficients (“DCT matrix”).

  • Patent number: 6243728
    Abstract: A partitioned shift right logic circuit that is programmable and contains rounding support. The circuit of the present invention accepts a 32-bit value and a shift amount and then performs a right shift operation on the 32-bits and automatically rounds the result(s). Signed or unsigned values can be accepted. The right shift circuit is partitioned so that the 32-bit value can represent: (1) a single 32-bit number; or (2) two 16-bit values. A 1 bit selection input indicates the particular partition format. In operation, if the input value is not negative, then one (“1”) is added at the guard bit position and a right shift with truncate is performed. If the input is negative and the guard bit is zero, then no addition is done and a right shift with truncate is performed. If the input is negative and the guard bit is one and the sticky bit is zero, then no addition is done and a right shift with truncate is performed.
