  • Control of frame types in video compression
    Patent number: 7848424
    Abstract: A method of controlling frame types in a video compression system having I, P and B frames calculates activity figures of the video signal in vertical, vertical temporal and horizontal directions. Video sequences with low complexity in which the vertical activity within a field is less than the vertical-temporal activity within a frame are encoded without using B frames whereas sequences with high complexity, i.e. spatial detail, are encoded using B frames by the use of the invention, disadvantages associated with B frames are reduced by the selected use of B frames.

  • METHOD OF CODING AND DECODING IMAGE
    Publication number: 20100284463
    Abstract: A method of simplifying the arithmetic operation in a global motion compensation process approximates the motion vector field of the whole image without using many parameters. Motion vectors in the global motion compensation are found by the interpolation and/or extrapolation of the motion vectors of a plurality of representative points 602, 603 and 604 having particular features in the spatial distance thereof. Since the shift operation can be substituted for the division for synthesizing a predicted image of global motion compensation, the processing using a computer or a dedicated hardware is simplified.

  • Mode selection techniques for intra-prediction video encoding
    Patent number: 7830960
    Abstract: In one embodiment, this disclosure provides an encoding device comprising a mode selection engine that performs mode selection for intra-prediction encoding regardless of whether the encoding device is programmed to comply with first encoding standard or a second encoding standard. The device also includes a first encoder to perform the intra-prediction encoding according to the selected mode in compliance with the first encoding standard when the encoding device is programmed to comply with the first encoding standard, and a second encoder to perform the intra-prediction encoding according to the selected mode in compliance with the second encoding standard when the encoding device is programmed to comply with the second encoding standard. The techniques can simplify mode selection in support of multiple different intra-prediction encoding standards.
