摘要： The present invention provides a video encoding device in which a capacity of a binary data storing unit is small, a size of the video encoding device is small, a video signal can be processed in real time, and reduction in quality of images generated from the eventually obtained data can be prevented. The video encoding device according to the present invention includes: a video encoding unit which encodes a video signal; a binarization unit which binarizes an encoded value obtained from the video encoding unit; and an entropy encoding unit which subjects entropy encoding to binary data obtained from the binarization unit. Here, the video encoding unit encodes the video signal based on a characteristic of the binarization performed by the binarization unit, so that an amount of binary data obtained from the binarization unit by binarizing the encoded value that is encoded based on the characteristic is less than an amount of binary data obtained by binarizing an encoded value that is encoded without being based on the characteristic.

摘要： In a recording apparatus for video signals, adjacent pixels in input image signals are collected as blocks and subjected to orthogonal transformation. Then, the dc component, control data, ac components, end-of-block signal and the like in a block after orthogonal transformation are coded and the codewords are arranged in prescribed record areas. One or a plurality of record areas forms a correction area, and error correction coding is performed and recorded on the data in a correction area. When record data are reproduced and recorded again, errors are detected in the unit of the error correction area. The dc component and the like in a record area wherein an error which cannot be corrected exists are replaced by a codeword which is not used ordinarily, and a codeword for the first ac component is replaced by an end-of-block codeword.

摘要： In a digital video signal recording and reproducing apparatus using bit rate reduction coding, information multiplexed to each record block is selected depending on the reproducing process applied to reproduce record blocks. When error correction is carried out and then, error concealment is applied to any record block having an error uncorrectable by the error correction, error concealment information indicating that the error concealment was carried out is multiplexed to the record block to be outputted. Also, since the continuity of bit rate reduction encoded data may be broken by concealing a part of record blocks, decoding information for controlling the decoding of bit rate reduction encoded data is multiplexed to the record block to be outputted. When an error concealment is not carried out in the bit rate reduction encoded state, an error flag indicating that an error exists is multiplexed to the record block to be outputted.

摘要： A coded digital video signal is obtained by dividing a digital video signal into plural pages each composed of K fields of pixel data, decomposing pixel data in each two pages into plural blocks each composed of a predetermined number of pixel data, and encoding the pixel data in each block by bit rate reduction encoding and error correction encoding. The thus obtained coded digital video signal is reproduced or transmitted and then subjected to a concealment process. The concealment process includes decoding the coded digital video signal to obtain reproduced blocks of pixel data and to detect an error block containing an error among the reproduced blocks, composing the reproduced blocks to obtain plural reproduced pages of pixel data, and concealing error pixel data contained in the error block in each two reproduced pages. Error pixel data in a first page is concealed using pixel data in a previous page, and error pixel data in a second page is concealed using pixel data in a succeeding page.

摘要： A signal processing apparatus for use in a digital video signal reproducing apparatus for reproducing digital signal presented in sync blocks is disclosed. Each sync block has a fixed area for low frequency data and five subsequent sync blocks define a sharing group for sharing high frequency data. The signal processing apparatus includes an inner and outer correction circuit for correcting errors in the sync blocks. An error flag is provided to a sync block which still has an error remaining after the processing in the correction circuit. A memory is provided for storing errorless sync blocks of one frame. A substitution switch is provided for passing the errorless sync blocks, but substituting a sync block stored in the memory for a sync block still having some errors. Five sync blocks produced from the substitution switch are held in a delay. When no substitute sync block is detected in the five sync blocks in the delay, the data in the five sync blocks are decoded by a bit rate reduction decoder. But, when one to four substitute sync block is detected in the five sync blocks in the delay, only the low frequency data of the five sync blocks in the fixed area are decoded by the bit rate reduction decoder.

摘要： In the recording apparatus and reproducing apparatus employing variable length coding, a formatting which prevents propagation of error due to transmission route error is realized. The input quantized value is coded in variable length and recorded in a first memory. The variable length code words recorded in the first memory are read out and formatted, and recorded into a second memory. In reproduction, the quantized value is decoded in the reverse sequence. By executing variable length coding and formatting in a pipeline operation by using two memories, high speed input signals such as moving picture signals can be formatted. Components of the recording apparatus and reproducing apparatus can be shared, and the circuit scale may be effectively reduced.
