    摘要: Methods and apparatus for encoding, decoding and displaying images in a manner that provides for relatively smooth motion are described. In accordance with the invention a multi-sync display device is used and the refresh rate of the display device is controlled to minimize or avoid judder. Control of the display device refresh rate is performed in various embodiments, as a function of frame display, frame coding, field coding and/or image capture rate information included in an encoded bitstream. Alternatively, the refresh rate of a display is controlled as a function of decoding rate information or other information available from a decoder. In one exemplary embodiment, frames are displayed and the refresh rate of a display device is controlled to be an integral multiple of the indicated frame display rate included in an encoded bitstream. In accordance with an encoding feature of the present invention, refresh rate control information is included in an encoded video bitstream and used by a display system to control the refresh rate of a display device used to display images represented by the encoded video bitstream. The refresh rate control information is information which is not necessary for decoding but useful in achieving high quality display of the images. In accordance with the refresh rate control methods of the invention, a display device's refresh rate may vary depending on the video being displayed.

    摘要: Methods and apparatus for implementing video decoders at a reduced cost are described. The methods include data reduction techniques, simplified inverse quantization techniques, and dynamically varying the complexity of image enhancement operations, e.g., prediction filtering operations, as a function of whether luminance or chrominance data is being processed. In order to reduce data storage requirements, luminance and chrominance data corresponding to previously encoded images may be stored at different resolutions with, in some embodiments, chrominance data being stored at less than half the resolution of luminance data. In various embodiments, data representing portions of B frames which will not be displayed is identified and discarded, e.g., without performing a decoding operation thereon. Portions of I and P frames which will not be displayed are identified and decoded at a reduced resolution and/or using simplified inverse quantization techniques. The decoded I and P frame data is stored for use when making subsequent predictions if required. Another data reduction technique involves applying different amounts of data reduction, e.g., downsampling, to different image portions with no or little downsampling being performed on image portions located at or nearest to the image's center of interest as determined from information included in a received encoded bitstream.

    摘要: A 3-dimensional (3D) video rendering device may convert a first left view video of a decompressed 3D video having a first frame rate to generate a second left view video having a second frame rate, and convert a first right view video having the first frame rate to generate a second right view video having the second frame rate. The second left view video having a particular pixel resolution may be converted by the 3D video rendering device to generate a third left view video having full pixel resolution of the decompressed 3D video. The second right view video having the particular pixel resolution may be converted to generate a third right view video having the full pixel resolution. The 3D video rendering device may generate a sequence of video frames for 3D video display based on the third left view video and the third right view video.

    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.
