摘要： In a digital video signal recording/reproducing apparatus for recording digital VCR video and audio signals by using a rotary cylinder, for a video signal with a frame frequency fN of 30 Hz or 29.97 Hz, the rotating frequency of the cylinder is set to 2.5 times fN. On the other hand, for a signal with a frame frequency fP of 25 Hz, the rotating frequency of the cylinder is set to 3.0 times fP. As a result, as long as the cylinder diameters are identical, the relative speed of the tape and the head is the same for video signals of either frame frequency fN or fP.

摘要： A method for transmission of variable length code words is provided in which the variable length code words are allocated into a data storage field not only from the front end of the same but also from the rear end, whereby unwanted affection by transmission error will be minimized. A coding apparatus produces coded data of such a format that after different type video signals are divided into a common signal area and a not-common signal area, the coded data of the common signal area is allocated into one data storage field in a sequence from the front end of the same and the coded data of the not-common signal area is allocated in a reverse sequence from the rear end. Accordingly, such different video signals can successfully be decoded with a decoder designed for processing one particular video signal.

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.
