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.

摘要： An information recording apparatus implements the orthogonal transformation for the input signal on a block-by-block basis, separates each variable-length coded word into a fixed part and separate part individually, records the fixed part into a record block which is established for each block of orthogonal component by starting from the beginning and ending at the prescribed position of the record block, and records coded words of the separate part into remaining portions of record blocks.

摘要： Disclosed is an orthogonal transformation encoder in which after horizontal orthogonal transformation is performed, in parallel to the horizontal and vertical rearrangement of the coefficients for performing vertical orthogonal transformation, detection of interfield coefficient is performed and intra-frame/intrafield modes for the vertical orthogonal transformation are switched. Further, in parallel to the rearrangement of the transformation coefficients for the vertical orthogonal transformation to be in the ascending order from a lower frequency component to a higher frequency component, the amplitude values of the AC components in the block in question are detected to thereby make control on the basis of the amplitude values so that the smaller the amplitude value of the block the smaller the quantizing step width.

摘要： For recording video signals of different TV systems in the same track format, effective pixels corresponding to the data of one frame of each TV system video signal are divided into segments of a multiple of 27 and a one frame data component of each segment is compressed to an equal size. Accordingly, the video signal is recorded in the format of 27 segments per track.

摘要： A data round-off device receives a digital input signal of m-bit form (m is an integer) which has arithmetically been processed by addition, subtraction, multiplication, and division by an orthogonal transformer or predictive encoder is summed, if it is positive, with a value of 2.sup.(n-1) -1 (n is a natural number smaller than m) and if negative, with a value of 2.sup.(n-1) and the higher (m-n) bits of a resultant sum signal are delivered as the output of the data round-off device. Preferably, it is used for control of the number of bits if there is a difference in the number of bits between the data output of an orthogonal transformer and the data input of an encoder for encoding the data output of the orthogonal transformer.

摘要： A video signal digital recording and reproducing apparatus includes: a rearranging section for rearranging a sequence of signals on a rectangular unit by rectangular unit basis formed by sectioning a group of pixel data on a screen of a digital video signal; an encoding section for subjecting the signals in the rectangular units to bit rate reduction; a block forming section for gathering plural number of the coded rectangular units to constitute a block of signals, and a recording the block of signals section for recording on a recording medium. The rearranging section divides the screen into plural regions, takes out the rectangular units by a certain number in order from each region, and carries out rearrangement so that mutually corresponding rectangular units which are contained respectively in adjacent blocks on the recording medium are mutually adjacent on the screen. The recording section is constituted so that the blocks signals are recorded simultaneously in parallel on the recording medium by using plural channels. The rearranging section may have such a constitution that the screen is divided into plural regions and the rectangular units are taken out by a certain number in order from each region, and rearrangement is carried out to that mutually corresponding rectangular units which are contained respectively in adjacent or neighboring blocks to be simultaneously recorded in parallel by the plural channels on the recording section are mutually adjacent on the screen.
