摘要： A digital video transcoder-multiplexer (transmux) architecture that is fully software-implemented. The transmux (200) includes transcoder processing elements (TPEs) (240) that may use a very long instruction word (VLIW) media processor (105) for performing transcoding, and de-assembly and re-assembly at a transport stream level, and a co-processor (131) for providing de-assembly and re-assembly at an elementary stream level. The processors operate in parallel, at least in part, to optimize throughput and provide processing load balancing. A transmux architecture that is fully software implemented is provided to allow upgrading to handle new functions, fix hardware or software problems, test new processes, adapt to changing customer requirements, and so forth.

摘要： A method and apparatus are disclosed by which a translucent logo is inserted into the transcoded digital bitstream of an MPEG transcoder without changing the digital nature of the bitstream. Such an MPEG transcoder has cascaded decoding and encoding sections. A translucent logo is generated and is added to the reconstructed video image produced by the decoder section of the MPEG transcoder upstream of the transcoder's encoding section. The encoding section of the transcoder then encodes the bitstream which includes the translucent logo.

摘要： A transcoder architecture that provides the lowest possible complexity with a small error, e.g., for converting an MPEG-2 bitstream into an MPEG-4 bitstream. The transcoder reads header information (304) from an input bitstream and provides a corresponding header in the new format for the output bitstream. In one embodiment (Fig. 3), a low complexity front-to-back transcoder (with B frames disabled) avoids the need for motion compensation processing. In another embodiment (Fig. 4), a transcoder architecture that minimizes drift error (with B frames enabled) is provided. In another embodiment (Fig. 5), a size transcoder (with B frames enabled) is provided, e.g., to convert a bitstream of ITU-R 601 interlaced video coding with MPEG-2 MP@ ML into a simple profile MPEG-4 bitstream which contains SIF progressive video suitable for a streaming video application. For spatial downscaling of field-mode DCT blocks, vertical and horizontal downscalling tehniques are combined to use sparse matrixes to reduce computations.

摘要： An automatic sprite generation system uses first-order prediction for initial estimation, delayed elimination for outlier rejection, and field-based sprite generation for an interlaced source. Higher-order prediction for the initial estimation may be used to handle more complicated motion. The invention addresses outlier and fast motion problems that are not handled by the existing MPEG-4 scheme. Automatic sprite generation is provided by performing shot detection (e.g., panning or zooming) on the input images to provide a group of successive images that share a common scene for use in forming a sprite. The initial estimation of motion parameter data for forming the sprite uses the motion parameter data of at least two previous input images. Delayed outlier rejection is performed in two steps by eliminating pixels whose error increases in successive sprite iterations. For interlaced input images, a sprite and set of motion parameters are encoded and transmitted for each field separately.

摘要： A system for converting the color format of a digital video bitstream. The system accounts for the allowable formats of the pre- and post-conversion bitstreams, including quantizer (355) precision level, and whether luma and chroma data have separate quantization matrices (385, 390), or share a common quantization matrix. In a particular implementation, an MPEG-2 4:2:2P bitstream having a color format of 4:2:2 or 4:2:0 is converted to an MP bitstream having a color format of 4:2:0. Coding efficiencies are achieved by using the luma quantization matrix (390) to re-quantize the chroma data, and re-using luma motion vectors MV for performing motion compensation (320, 325, 510) of the chroma data. Further efficiencies can be achieved by representing a 4:2:2 reference picture in a 4:2:0 format for converting intercoded frames, and changing the position of a pixel downsizing filter (340) and clip function (335). Adjustment (130, 230, 382), of the quantization precision is provided as required. A transcoding function (800) can also be achieved.
摘要翻译：一种用于转换数字视频比特流的颜色格式的系统。系统考虑了转换前和转换后比特流的允许格式，包括量化器（355）精度级别，以及亮度和色度数据是否具有单独的量化矩阵（385,390），或共享公共量化矩阵。在具体实现中，将具有4:2:2或4:2:0的颜色格式的MPEG-2 4：2：2P比特流转换为具有4:2:0的颜色格式的MP比特流。通过使用亮度量化矩阵（390）来重新量化色度数据并重新使用亮度运动矢量MV来执行色度数据的运动补偿（320,325,510）来实现编码效率。通过以4：2：0格式表示4：2：2参考图像来转换帧间编码帧，以及改变像素缩小滤波器（340）和剪辑功能（335）的位置，可以实现更高的效率。根据需要提供量化精度的调整（130,230,382）。还可以实现代码转换功能（800）。

摘要： PROBLEM TO BE SOLVED: To consistently maintain video quality by applying any additional quantized bit to disparity predicted P image when encoding a P frame from a B frame in a base layer. SOLUTION: Inside the base layer, 12 pieces of images from Bb1 652 to Pb2 674 correspond to a reinforce layer GOP and in this base layer sequence of 12 pieces of images, two I images exist at the start point of base layer GOP. The intra-reinforce layer images corresponding to these I images are switched to different image types for encoding. For example, an intra-base layer image Ib1 656 is switched to an intra-reinforce layer image PD1 60, and an intra-base layer image Ib1 668 is switched to an intra-base layer image PD2 618. Besides, the reinforce layer image corresponding to base layer GOP start is switched to the I image. Thus, the B image is switched to any one of P and I images in the reinforce layer.

摘要： PROBLEM TO BE SOLVED: To impart a temporal and spatial scalability function for encoding a video signal including a video object plane(VOP) by differentially encoding an up sample VOP, which is provided from the VOP of an input video sequence, while using the VOP of the input video sequence.

One specified piece of pixel data in the VOP of the input video sequence are down-sampled, and a base layer VOP having a decreased spatial resolution is given. The pixel data in the base layer VOP at one part at least are up-sampled, and an up-sampling VOP is given in a reinforced later. The up-sampling VOP is differentially encoded, while using specified one VOP of the input video sequence.

摘要： PROBLEM TO BE SOLVED: To obtain a device in which the coding efficiency of an enhancement layer image which is predicted by means of a disparity is improved by shifting a lower-order layer image and obtaining a reference image through the use of an optimum offset value between the enhancement layer image decided, in accordance with least an average error or least an average square error and the lower-order layer image. SOLUTION: An optimum offset value x is decided, in accordance with least an average error or the least average square error between the image element values of a right image 510 in an enhancement layer and a left image in a low-order layer. Then, the last x column 520 at the right side of the left image 535 is erased, the first x column is embedded in the respective rows of the left image 540, and an area 530 is formed at the left side of the left image 540. The right image is predicted by the disparity through the use of the shifted reference image 540 which matches more closely with the corresponding right image obtained by the result. Thus, a device with which the coding efficiency of the enhancement layer image is improved is obtained.
