    • 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.
    • 描述了以降低的成本实现视频解码器的方法和装置。 该方法包括数据简化技术,简化逆量化技术,以及动态地改变图像增强操作的复杂性,例如预测滤波操作,作为是否正在处理亮度或色度数据的函数。 为了减少数据存储要求,与以前编码的图像相对应的亮度和色度数据可以以不同的分辨率存储,在一些实施例中,色度数据被存储在亮度数据的分辨率的一半以下。 在各种实施例中,表示不显示的B帧的部分的数据被识别和丢弃,例如不对其执行解码操作。 以降低的分辨率和/或使用简化的逆量化技术来识别和解码不显示的I帧和P帧的部分。 如果需要,进行后续预测时,解码的I和P帧数据被存储以供使用。 另一种数据缩减技术涉及对不同的图像部分应用不同数量的数据缩减,例如下采样,在从包含在接收的编码比特流中的信息确定的位于或最靠近图像的感兴趣中心的图像部分上执行没有或很少的下采样 。

    • 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.

    • 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.
    • 公开了一种用于降低复杂度的具有特殊色度处理的视频和图像处理的方法和装置。 在由一系列帧组成的视频流上进行帧型决定。 帧的第一子集被选择为单色并且没有色度数据生成。 帧的第二子集被选择为彩色并由色度分量生成。 在一个实施例中,帧的第一子集包括奇数帧,并且帧的第二子集包括视频流中的偶数帧。 在更高的视频帧速率下,每个其他帧中缺少颜色对于终端观看者是不可见的。 因此,输出视频流的后续处理允许在视频流中许多帧的仅亮度处理,从而大大减少了计算量。
