    • 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.

    • In a TV transmission system which operates on the ''letter box'' principle for transmitting the 16:9 aspect ratio, every fourth line is removed and transmitted in a compatible form as additional information at the upper and lower edges of the picture with the 4:3 format. This process, however, leads to signal jumps and distorted movements and to reduced vertical definition in the 4:3 receiver and to greater sensitivity to noise in the 16:9 receiver. These drawbacks are largely overcome, and in particular the static definition of the 4:3 receiver is maintained, by using a vertical DCT of length eight and an inverse DCT of length six in the encoder of the transmitter and vice versa in the decoder of the 16:9 receiver.
    • 在以“信箱”原理操作以传输16:9宽高比的电视传输系统中,每四行被去除并以兼容形式发送,作为附加信息在图像的上边缘和下边缘,具有 4:3格式。 然而,这个过程会导致信号跳变和失真运动,并降低4:3接收机中的垂直分辨率,并提高对16:9接收机噪声的敏感度。 这些缺点在很大程度上得到克服,特别是通过在发射机的编码器中使用长度为8的垂直DCT和长度为6的逆DCT,维持4:3接收机的静态定义,反之亦然。 16:9接收器。

    • Digital signal processing system for batch-bulk coded signals. A signal batch-bulk coded with variable word length is transmitted at high speed. The signal stored in coded form cannot be read continuously at high speed. During transformation, either several blocks of constant word length are assembled from equal, important and less important interchangeable components, respectively, grouped into super blocks and provided with a position information, or alternatively the equal, important and less important interchangeable components and the addresses of the interchangeable components are grouped within larger segments, which may also include a complete picture, and the segments are provided with a position information. During high-speed transmission (search mode), either superblocks or segments in which only equal or important interchangeable components, respectively, are decoded are arranged as an output signal at given intervals in accordance with their position information. The invention is applicable to blockwise signal processing.

    • DE 37 02 490 describes a process for data transmission in which data from pixel blocks are converted into digital signals which are coded with variable word length. Here the digital signals are displayed in blocks of an average length. Incomplete blocks are filled out with data from other blocks. To improve interference sensitivity, d.c. components and important a.c. components are dispayed at fixed intervals. If errors have occured on the transmission channel (6) or storage medium (6), the data of a block distributed over other blocks cannot, however, be decoded. According to the invention, an address information flag (FL) and address pointer information (POI) are added to each block at a fixed position as well as a d.c. value. With the aid of this additional information, improved resynchronisation is possible in the event of an error, where the a.c. components distributed over other blocks can also be recovered from stores (9, 10) and decoded.
