摘要： A coding and decoding device for a time-varying picture, by which a high picture quality is obtained from a smaller amount of information than a system using only DCT coding. The efficiency of coding can be increased and the block distortion of a composite image is reduced. An image is divided into several blocks, and each block is coded. At this time discrete cosine transformation coding (DCT) and intrablock predictive composing (NTC) are switched over to each other adequately according to the property of the image pattern. When the intrablock predictive composing is executed, the predictive value and quantization width of a block are transmitted.

摘要： A decoder unit of a bit stream is provided on the monitor side only, and a reader unit of the bit stream, a decoder unit of the bit stream and a recorder unit of the bit stream are coupled together through a digital network. The reproducing apparatus simply reproduces the bit stream and the recording apparatus simply records the bit stream. The bit stream reproducing apparatus, the bit stream decoding device on the monitor side and the bit stream recording device are coupled together through a high-speed digital network. This makes it possible to constitute a dynamic image reproduction system by connecting a plurality of dynamic image reproducing devices to a single dynamic image display device enabling any source to be watched by changing over the switch, at a reduced cost and preventing the picture quality from being deteriorated.

摘要： A recording device is switched for high-speed reproduction in response to a high-speed reproduction control signal input from an external unit, and a signal read from the recording device is input to a VLD and a formatter. The high-speed reproduction control signal is input to the recording device, to the switch and to the counter. The recording device reproduces a predetermined data and outputs it according to the high-speed reproduction control signal. The VLD no longer effects the variable length encoding of MPEG, and executes the syntax analysis. The counter counts the number of frames being transmitted. Temporal_reference is output depending upon the speed of reproduction indicated by the high-speed reproduction control signal. The header converter rewrites temporal_reference in the picture header in response to temporal_reference output from the counter. It is thus made possible to reproduce the dynamic image at high speeds.

摘要： When a moving image is encoded, a region for effecting intro-coding is dispersed into part of a screen unit but not into the whole screen such as a frame or a field. Further, a flag representing its structure is added. The structure of encoded image data is modified for high speed reproduction in accordance with the data of the flag, and is transmitted or recorded. When the encoded data is decoded, the region for which decentralized intra-coding is effected is decoded by using the multiplexed flag, and smooth and high speed normal or reverse reproduction is made. Accordingly, the present invention can accomplish an encoder, a recorder, a device for recording/transmission formatting (bit stream syntax) and reproduction, and a decoder in order to smoothly reproduce a moving image data at a high speed either in normal or reverse mode.

摘要： A highly efficient coding/decoding by subjecting image signals to orthogonal transformation, by which all data of interlace images, inclusive of scarce and rich types of images in motions and even a mixed type thereof, can be coded efficiently. A circuit (19) senses motion vectors in every macro-block between an odd-numbered field and an even-numbered field. A circuit (21) determines the coding mode (coding of every field or coding of every frame), according to the median of the motion vectors. A control circuit (16) controls gates (15, 17) and switches (6, 9, 10, 15) corresponding to the determined coding mode, and it generates a predictive image of every field or frame from buffer memories (7, 8). Circuits from a difference circuit (22) to a VLC circuit (25) calculate the difference data between an image to be coded and the predictive picture thereof, subject the difference data to discrete cosine transformation, and thereafter perform variable-length coding. Also, the VLC circuit (25) sets the coding mode as a flag in the header of the predetermined hierarchy of a bit stream.
