    摘要: In a recording system, a sequence of image signals obtained from a sequence of images are used to generate and record a sequence of recordable signals on a read only memory. Efficient coding of the received sequence of image signals is carried out through the use of a given parameter which is adaptively and dynamically changed, preferably manually, through a parameter controller acting as the interactive device. The image signals are repeatedly subjected to the efficient coding process. The process uses a sequence of predictive signals to produce coded signals. The predictive signals are displayed on a monitor display device to be monitored by an operator. The operator changes the attributes of the parameter until an optimum image is obtained. The optimum parameter is stored on a magnetic tape. The image signals subjected to the efficient coding enable the production of a sequence of coded image signals which are recorded on the read only memory in synchronism with the optimum parameter, after the optimum image has been obtained.

    摘要: On encoding a cluster and run sequence comprising clusters of non-zero signal elements and runs of zero signal elements into a code sequence with application of a compression encoding scheme selectively to the clusters and without application of the encoding scheme to the runs, a mode code is used to indicate application of the encoding scheme to each selected cluster and to represent a zero signal element next preceding the selected cluster in a next preceding run. In the code sequence, the mode code next precedes a succession of amplitude codes representative of the selected cluster and next succeeds a run length code preferably representative of that run length of the next preceding run from which the next preceding zero signal element is reduced. Alternatively, the mode code may indicate switching between application and non-application of the encoding scheme to partial sequences each of which starts with a cluster next succeeded by a run. In either event, a particular code is preferably used to indicate an end of each run. On decoding, the mode code is detected preferably with reference to the particular code to decide whether or not each amplitude code succession should be decoded according to an expansion decoding scheme which corresponds to the encoding scheme.

    摘要: A video signal compression circuit for encoding a video signal to reduce the quantity of video information that is transmitted without loss of information, and a video signal decompressing circuit for recovering the video signal from its compressed coded form. The encoding circuit includes means for dividing the video signal of each television frame into blocks, each block including a plurality of picture elements distributed over several scan lines. The information in each block is analyzed to detect image movement in that block and a movement detection signal corresponding to each block is produced. Thereafter, the movement detection signal is rearranged to have a time sequence which corresponds to the sequential order of the picture elements in the original video signal. With the help of the rearranged movement detection signal, the original video signal is coded in accordance with a predictive-coding scheme into a form which allows it to be transmitted over a television signal carrier. In alternate embodiments, the movement detection signal remains in a time sequence which corresponds to its block form and instead the video signal is converted to have a time sequence which corresponds to the time sequence of the movement detection signal.

    摘要: A television signal coding system is designed to avoid any increase in the volume of information transmitted resulting from transmission of unnecessary picture elements, while at the same time reducing the volume of address information required. The picture elements are compared one by one between successive frames, and the magnitude of the frame-to-frame differences is compared with a predetermined threshold value to determine whether the change is significant or not. A predetermined number of consecutive picture elements forms a unit region. A line of horizontal scan is divided into regions, each including a predetermined number of unit regions, and for each of such regions the decision is made as to whether it includes at least one significant unit region or not. Each of the significant regions is further divided, and for each of the resulting divisions the decision is made as to whether it is significant or not. In this manner, each scanning line is divided step by step until a train of significant unit regions is obtained. The code resulting from the several divisions is used as the address information.

    摘要: In a transmitting system, a first multiplexer multiplexes first through M-th encoded digital video signals from encoders to produce a primary multiplex signal comprising cells which have channel codes, address codes, and cell data, where M represents an integer greater than two. Each of the cell data represents a part of one of the encoded digital video signals. Each of the channel codes indicates one of the encoded digital video signals. Each of the address codes indicates a position of one of the cell datum. A first demultiplexer demultiplexes the primary multiplex signal to produce first through N-th primary demultiplex signals, where N represents an integer which is less than M and greater than one. A second multiplexer multiplexes the first through the N-th primary demultiplex signals from the first demultiplexer through first through N-th transmitting paths to produce a secondary multiplex signal. A second demultiplexer demultiplexes the secondary multiplex signal datum in response to the channel codes and the address codes to produce the first through the M-th encoded digital video signals.

    摘要: On detecting a drastic change, such as a scene change, between current and previous ones of successive pictures which are represented by a digital video signal and each of which comprises a predetermined number of picture elements, the digital video signal is processed by using correlations between the picture elements within each of the successive pictures to produce a processed signal which represents processed results for each of the successive pictures. A statistical distribution of the processed results is calculated from the processed signal. The statistical distribution of the processed results in the current picture is collated with the statistical distribution of the processed results in the previous picture to be produced as a change detection signal representative of the drastic change with reference to a relationship between the statistical distribution of the processed results in the current picture and the statistical distribution of the processed results in the previous picture. The processed signal may be obtained by producing a difference signal between the digital video signal and a prediction signal predictive of the digital video signal by using the correlations. Alternatively, an orthogonal transform is carried out for the digital video signal to produce the processed signal.

    摘要: In an image communication system, an input image sequence is converted into a block-formatted sequence. A data compression signal indicative of the amount of moving blocks in the block-formatted sequence is generated to individually control a plurality of vector quantizers each having a particular frequency band and a memory containing output vectors. The output vectors of each of the vector quantizers is representative of inverse orthogonal transform of a code table of optimum quantized vectors in the particular frequency band, the optimum quantized vectors being orthogonal transform of interframe differential training image sequences. The output vectors is retrievable from the memory as a function of an interframe differential image sequence, or prediction error. Each vector quantizer selects one of the vectors retrieved from the memory which is nearest to the value of the interframe differential image sequence and generates an index signal representative of the selected vector, which index signal is encoded and transmitted to a destination. The outputs of the vector quantizers are processed by inverse vector quantizers to generate a predictive image sequence. The prediction error is detected as a difference between the predictive image sequence and the block-formatted sequence.

    摘要: In a predictive encoder for use particularly in a conference television system, a signal processing unit is used in producing a prediction signal and comprises three prediction circuits (22, 23, 31) and a selection circuit (24) coupled to the prediction circuits. The prediction circuits are for producing an inframe, an interframe, and a background prediction signals, respectively. Those signals are produced by processing an original signal at instants which precede a current instant and are different from one another. The selection circuit is for selecting one of the inframe, the interframe, and the background prediction signals. Therefore, it is possible to produce the prediction signal suitably predictive of the original signal. The signal processing circuit serves equally well in a predictive decoder.
