Abstract: Encoded data is reversely reproduced by decoding each picture only once and using only as many frame memory sections as are needed in a normal playback operation. A picture header detector detects a picture header from data read out from a video code buffer to identify the type of picture. The picture type information controls a picture data selecting circuit for selecting frames of I and P pictures equal in number to the number of frame memory sections in a frame memory bank. The selected frames are supplied to an inverse VLC circuit to be decoded, starting at the head of a GOP with an I picture. The decoded I and P pictures are stored in the frame memory bank and transmitted to a display unit, starting with the temporally most recent picture and reading backward.

Abstract: A tape cassette includes a first rib (25) projecting upwardly from a bottom wall (23) of a cassette case (2) at a position between a middle and one side of a tape drawing recess (7) formed on a front surface of the cassette case (2), the first rib (25) being disposed close to the rear surface of the tape (13) in the cassette. A second rib (30) projects from a back lid (17) so that, when the back lid (17) is rotated to reach an open position, the second rib (30) is kept in contact or proximity to an upper end of the first rib (25). When the back lid (17) is in the open position, the second rib (30) is disposed in contact or proximity to the upper end of the first rib (25), thereby avoiding any gap between the first rib (25) and the second rib (30). Accordingly, even when a part of the tape (13) is lifted by the back lid (17) in a lid opening operation, there is no possibility of the tape (13) passing to the rear side of the first rib (25), thereby preventing risk of tape jamming and damage to a tape player.

Abstract: OF THE DISCLORURE An apparatus for recording an information signal that includes a signal processor for processing an information signal to be magnetically recorded, n magnetic heads (n is an integer of 2 or more) provided on a rotating drum with a step of about 1/n the width of a magnetic tape and a distributing circuit for selectively supplying the processed information signal to one or more than two of the n magnetic heads, wherein the processed information signal is recorded on one or more than two track areas of the magnetic tape by the magnetic head. Thus, much data can be recorded at a high transmission rate to improve the quality of picture, and also, a high access speed can be achieved.

Abstract: A video signal recording apparatus for recording a video signal on a magnetic tape includes an oscillator which generates an oscillation signal; a variable frequency divider for frequency dividing the oscillation signal; a control circuit for controlling the frequency-dividing ratio of the variable frequency divider in accordance with the speed of advancement of the magnetic tape during the recording operation; a frequency divider for generating a plurality of synchronizing signals in response to the output of the variable frequency divider; a camera including an image transducer from which the video signal is obtained in correspondence to incident light from an object image projected on the image transducer, and a transmission device for transmitting the signal from the image transducer at a rate determined by the synchronizing signals; and a recording section including a processing circuit for separately processing the luminance and chrominance components of the transmitted video signal, and at least one transducer for recording the processed video signal on the magnetic tape in response to the synchronizing signals, wherein the video signal is always recorded on the magnetic tape in the same format regardless of the speed of advancement of the magnetic tape during the recording operation.

Abstract: Encoded data is reversely reproduced by decoding each picture only once and using only as many frame memory sections as are needed in a normal playback operation. A picture header detector (34) detects a picture header from data read out from a video code buffer (10) to identify the type of picture. The picture type information controls a picture data selecting circuit (35) for selecting frames of I and P pictures equal in number to the number of frame memory sections in a frame memory bank (16). The selected frames are supplied to an inverse VLC circuit (11) to be decoded, starting at the head of a GOP with an I picture. The decoded I and P pictures are stored in the frame memory bank (16) and transmitted to a display unit (18), starting with the temporally most recent picture and reading backward.

Abstract: High-speed access to a multi-layered disk is to be realized. Each layer on a multi-layered disk may include an inside guard area 2, program area 3, and outer guard area 5 which are located in uniform radial positions in all layers. The uppermost layer has the recording direction from the inner side to the outer side of the disk, and the next layer has the recording direction from the outer side to the inner side of the disk such that opposite recording directions appear alternately. The radial position of the recording terminal end on the uppermost first layer may coincide with the radial position of the start of record on the next second layer. Recording and/or playback apparatus for such recording media is also provided.
