摘要： The bit rate control goals for applications using storage devices with the capability to process a variable bit rate data stream differ from the constant bit rate case. Therefore the encoder control strategy is adapted to this situation. For the first e.g. 80% of the total playing time an average bit rate is produced which is e.g. 95% only of the normal average bit rate. For the remaining 20% of the playing time the value for the desired average bit rate ascends to e.g. 150% of the normal value. During the first 80% the virtual buffer size is increased by a factor of e.g. 100 whereas during the last 20% the virtual buffer size descends to the normal value. Thereby an increased decoding quality can be achieved during e.g. 80% of the playing time. In the remaining playing time there is nearly no loss in the normal decoding quality.

摘要： A hybrid Discrete Cosine Transform (DCT) coder processes blocks of (e.g., 8.times.8) pixels from interlaced or progressive scanned image signals. Processing of image lines by the coder is modified in the presence of image motion to avoid switching between 8.times.8 and 2.times.(4.times.8) transformations. For motion, the lines of two vertically superimposed image blocks are rearranged to produce first and second modified blocks. The modified first block contains pixels from lines in a first field, and the modified second block contains pixels from lines in an associated adjacent second field.
摘要翻译：混合离散余弦变换（DCT）编码器处理来自隔行扫描图像信号或逐行扫描图像信号的（例如，8×8）像素的块。在存在图像运动的情况下，通过编码器对图像线进行处理以避免在8×8和2x（4×8）变换之间切换。对于运动，两个垂直叠加的图像块的线重新排列以产生第一和第二修改块。经修改的第一块包含来自第一场中的线的像素，并且修改的第二块包含来自相关联的相邻第二场中的线的像素。

摘要： A method and apparatus for the transmission of digital signals comprises the steps of forming at least two data channels carrying data packets, and eventually header data. The channels have different levels of error protection and include picture data, wherein the data packets within one of the channels have the same level of error protection, and wherein a super-ordinate channel has a higher error protection than a subordinate channel. Important information of a subordinate channel is then transmitted in a super-ordinate channel. The important information allows following erroneous reception of the digital signals an improved recovery of picture data decoding.

摘要： A method of making a hierarchical estimate of image motion for a television signal. A television signal video image is divided into blocks of fixed size, and motion relative to a second video image is determined for each block. Mutually non-overlapping pixel blocks are produced at a lower, more finely resolved hierarchical level. The center points of these blocks are used as the points for an analysis at a level that is located higher in the hierarchy. Preferably, points which lie between image lines and which do not represent real picture elements in the line raster, are investigated in the mutually non-overlapping blocks.

The cameras can be orientated to a common observation area. The apparatus is operable to estimate a combined positional data of a point in the 3D-space. of the observation area corresponding to a pixel or group of pixels of interest of the main image. The apparatus comprises first disparity means for estimating at least a first disparity data concerning the pixel or group of pixels of interest derived from the main image and the first satellite image, second disparity means for estimating at least a second disparity data concerning the pixel or group of pixels of interest derived from the main image and the second satellite image, and positional data means for estimating the combined positional data of the point in the 3D-space of the observation area corresponding to the pixel or group of pixels of interest. The positional data means is operable to estimate first positional data on basis of the first disparity data and second positional data on basis of the second disparity data, and to combine the first positional data and the second positional data to the combined positional data.

摘要： Motion compensated temporal prediction is well-known for redundancy reduction in video signal compression. A prediction error signal and a motion vector for a current block are transmitted, describing the location of the predictor block in the reference picture. A problem solved by the invention is to encode and decode video signals using less or no mo- tion vector data side information. This is achieved through a temporal prediction which exploits common knowledge available in both encoder and decoder, requiring that the decoder performs a motion estimation, too. A common baseline motion estimation process is used at both encoder and decoder on the same set of video data that have already been compressed before and, hence, are available at both encoder and decoder, leading to identical motion parameters being generated in the decoder. These common motion parameters are used for generating a default temporal prediction without the need to transmit related motion vectors from the encoder to the decoder.
