摘要： Device for transmitting or storing digital television pictures in which a maximum possible number of data of a group of transformed pixel blocks (DB.sub.1 . . . DB.sub.12) is transmitted in the form of variable-length code words (V.sub.1 . . . V.sub.N) in a corresponding channel block of predetermined length (FIG. 5A). If all code words of the groups of blocks are accommodated in the corresponding channel block (FIG. 5C), the channel block will also comprise surplus data of other blocks. The boundary, within a channel block, between these code words and surplus data is transmitted in the form of an address (P) which is accommodated at a predetermined position of the channel block. If the channel block length is inadequate for transmitting all code words of the group of blocks, the channel block (FIG. 5B), will comprise at least the code words which are representative of the DC coefficient and a number of important AC coefficients of each block. Said code words are accommodated in successive channel block sections (L.sub.1 . . . L.sub.12), with a code (C) for the length of these channel block sections being transmitted at predetermined positions of the channel block.

摘要： A variable-length decoder variable-length-decodes a received variable-length-encoded data. The variable-length-encoded data is bit-stuffed in each data block to create data portions with a predetermined number of bits. Frame start codes representing a start of each frame and mass of macroblock start codes distinguishing between a plurality of masses of macroblocks are inserted into the data. Synchronization of data between frames and masses of macroblocks are accomplished via: a first-in-first-out (FIFO) memory which stores encoded data; a decoder which variable-length-decodes the input data in response to a control signal and generates an end-of-block (EOB) error signal when an EOB is not found; a decoding interface which interfaces between the decoder and a timing controller; and a timing controller which synchronizes decoding by use of start and initialization signals.

摘要： At the transmitter side of a signal transmission system, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between the first and second data streams is developed by shifting the signal points to other positions in the space diagram. At the receiver side of a signal transmission, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into two, low and high, frequency band components which are designated as a first and a second data stream respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability.

摘要： A system of distributing video and/or audio information employs digital signal processing to achieve high rates of data compression. The compressed and encoded audio and/or video information is sent over standard telephone, cable or satellite broadcast channels to a receiver specified by a subscriber of the service, preferably in less than real time, for later playback and optional recording on standard audio and/or video tape.

摘要： An image representing input signal is processed so the data therein are filtered in a predetermined manner to derive a filtered signal. The values of the filtered signal are combined at successive time intervals, and the values are combined so there is an addition of a function of values of the filtered signal at the successive time intervals to derive a combined signal. The combined signal is converted into a signal representing a predicted number of bits in a frame of the image. In response to the signal representing a predicted number of bits in a frame of the image, a signal representing the magnitude of a control for quantization step size is derived which is as a function of an error between the predicted number of bits and a predetermined target value therefor. A function of the input signal data is orthogonally transformed so a transformed signal is derived. Output data represented by the transformed signal are quantized so they have quantized step size determined by the control signal representing the magnitude of a quantization step size and there is a reduction in the number of data bits for the image relative to the number of data bits in the input signal.

摘要： In a picture signal coding/decoding method and a picture signal coding/decoding device, the compressibility and visual picture quality of the picture pattern whose inter field correlation of high frequency decreases and inter field correlation of low frequency remains when slow movement occurs are improved and transmitted. The intra field component separate coding is performed in each field on the first and second fields of picture signal respectively, and by preventing the effect of inter field movement in advance, the dropping of compressibility by the movement is avoided and furthermore, new blocks is constructed by the resultant low frequency components of two fields and since it is so arranged that the component separate coding is performed in the frame, low frequency components which are not easily affected by slow movement can be coded efficiently, and as a result, the compressibility for the picture containing slow movement can be increased.

摘要： A motion vector detection circuit detects the motion vector for each macro-block between an odd field and an even field. An encoding system decision circuit decides the type of the encoding system, that is if the encoding system is a field-based encoding system or a frame-based encoding system, based on a median of a motion vector. A control circuit controls gates and changeover switches, in accordance with the encoding system type as decided by the decision system, for generating a field-based reference picture or a frame-based reference picture from buffer memories. The circuitry from an additive node to a VLC circuit finds difference data between the reference picture and the picture to be encoded, while transforming the difference data by discrete cosine transform and variable length encoding the transformed data. The VLC circuit sets the encoding system type as a flag in a header of a predetermined hierarchical layer of a bit stream. By the above operation, any interlaced picture may be encoded efficiently, whether the picture includes little motion or abundant motion or includes both little motion and abundant motion in combination. A picture data decoding device detects the flag and executes decoding by changing over field-based decoding to frame-based decoding or vice versa depending on the flag for reproducing the picture data.

摘要： An ADRC encoder generates an ADRC block of 4.times.4 pixels, together with DR, MIN and quantized pixel data (DT) for each block. A macro block formatting circuit generates DR, MIN and DT code data for four ADRC blocks. An adding circuit generates sum data (DR.SIGMA.=DR1+DR2+DR3+DR4 and MIN.SIGMA.=MIN1+MIN2+MIN3+MIN4) of this hierarchical important data in the macro block. The sum data and the important data form which the sum data is formed are distributed and recorded in plural channels. If one of the important data has an error and the remaining important data and the sum data have no error, the important data with the error can be completely corrected. Reproduced pixel data is converted into 3.times.3 block format and an ADRC encoding circuit generates encoded data DTx representing a center pixel and DT data which represents the 8 pixels that surround the center pixel. A timing aligning circuit generates class information formed of the 8 pixel data, the class information being supplied to a memory as a read address for reading out existing-range data and predicted data DTx that had been stored therein during a learning operation. An error is detected by comparing the existing-range data to the encoded data Dtx; and when an error is detected, the predicted data DTx is selected.
