    摘要: Methods and apparatus for processing digital video data to reduce the amount of video data required to represent a video frame by representing a frame or pair of field pictures into a single field of a pair of field picture are described. To prevent the second field of the field picture from being displayed a DSM byte associated with the field picture is set so that only the field representing the video frame is displayed. In accordance with the present invention, a field, e.g., a transparent predictively coded field is used as the field picture which is not displayed. In this manner, very little data is required to represent the field picture that is not displayed. When the received frames are represented as pairs of field pictures a single field of the pair of field pictures is selected to represent the video frame with the other field picture being replaced with a field which requires very little data. When frame pictures are received one of a plurality of numerous described methods of mapping frame pictures into a single field of a pair of field pictures are used to convert the frame picture into a single field of a pair of field pictures. A plurality of methods for reducing the amount of data required to represent the single field of the pair of field pictures are also described.

    摘要: An image processing method for frame rate conversion, comprising: receiving a stream of input pictures at an input frame rate, at least some of the input pictures being new pictures, the new pictures appearing within the stream of input pictures at an underlying new picture rate; generating interpolated pictures from certain ones of the input pictures; outputting a stream of output pictures at an output frame rate, the stream of output pictures including a blend of the new pictures and the interpolated pictures, the interpolated pictures appearing in the stream of output pictures at an average interpolated picture rate; and causing a variation in the average interpolated picture rate in response to detection of a variation in the underlying new picture rate.

    摘要: Methods and apparatus for encoding image data to facilitate subsequent insertion of local image data. Also methods and apparatus for inserting image data, e.g., at local broadcast stations, without having to fully decode a received encoded bitstream. The encoding methods involve treating images to be encoded as a plurality of distinct, non-overlapping image regions or segments for encoding purposes. Image segments which are designated for use for local data insertion are not used as reference data for motion compensated prediction purposes when generating motion vectors to represent image areas, e.g., the area representing the main picture, which are outside the local data insertion segments. Because image segments which may be replaced are not used as reference data for image segments which will not be replaced, unintentional prediction errors which might otherwise result from replacing one or more image segments as part of a local data insertion operation are avoided.

    摘要: A method and apparatus of processing image data comprises receiving a video data signal where each pixel is represented by one or more digitized components, each digitized component being represented by a first set of binary digits and a second set of binary digits. The first set of binary digits is stored in a first memory plane and the second set of binary digits is stored in a second memory plane. The first set of binary digits is extracted and undergoes first and second processing. The second set of binary digits is extracted and undergoes second processing.

    摘要: A method and apparatus for reduced complexity video and image processing with special chroma handling are disclosed. Frame-type decisions are made on a video stream made up of a sequence of frames. A first subset of the frames are selected to be monochrome and generated without chroma data. A second subset of the frames are selected to be in color and generated with chroma components. In one embodiment, the first subset of frames includes odd frames and the second subset of frames includes even frames in the video stream. Under higher video frame rates, the lack of color in every other frame is not visible to the end viewer. Accordingly, subsequent processing of the output video stream permits luma-only processing of many frames in the video stream, extensively reducing the amount of computation.

    摘要: An apparatus for processing variable length coded data includes a coefficient buffer unit and several lookup tables. The coefficient buffer unit includes a coefficient memory and an index register for storing an indication of a non-zero nature of coefficients stored in the coefficient memory. Advantageously, the lookup tables may be altered to adapt the apparatus for processing variable length coded data to handle encoding or decoding video adhering to a specific standard. Furthermore, the lookup tables may be adapted to accelerate the determination of the presence of escape codes and the subsequent handling of the escape codes.
