摘要： PROBLEM TO BE SOLVED: To provide a transmission system which makes a decoder recognize an erroneous transmission data and enables the decoder to perform autonomous decoding processing on its side when a high efficiency compression coded data including a variable length coding is transmitted from a coding device to a decoding device.
SOLUTION: On a recording side, a code data is recorded with an address data added thereto, and on a reproduction side, an error correction circuit 93 detects an error in a reproduced data and outputs an error block address to a zero data creation control circuit 86. A zero data added with an error flag and a data length adjusting bit are input to a switch 88 from a switch 87, and also an output of the error correction circuit 93 is delayed by a delay circuit 85 and is input to the switch 88, and when the output of the delay circuit 85 is controlled by the zero data creation control circuit 86 and is an error block, the zero data is output instead of this error block.

摘要： PROBLEM TO BE SOLVED: To permit a user to select one of multiple scenes to enlarge the degree of freedom for selection by referring to multiple scene constitution information, generating a menu screen identifying a first data string and a second data string and supplying demodulation program information to a program information decoding means when selection information is inputted. SOLUTION: Plural pieces of program information which are mutually associated are stored in a disk 100. Thus, a reproduction device can reproduce arbitrary one from plural pieces of program information by the designation of the user and it can move to the other program information reproduction state from one program information reproduction state midway. Language information on various languages, audio information containing music information and environment sound information and caption information on the various languages are recorded in accordance with video information. Thus, a data string processing part 203, a system control part 204 and an operation part 205 constitute a data string control means and a scene selection means for deciding which information is to be reproduced.

摘要： PURPOSE:To obtain the same effect as shuffling without enlarging the propagation of error. CONSTITUTION:A writing signal generating circuit 34 writes a recording signal in a memory 32 with a frame unit. By controlling read out signals from the memory 32 with a frame unit, a 1 reading out signal generating circuit 35 records intensively the recording signal in the prescribed position in a recording region, while the circuit 35 varies a start position for reading so that an empty region is shifted, for example, with a frame unit. Thereby, coded data of a whole region of a screen is recorded in a recording track of either of a plus- azimuth or a minus-azimuth, the same effect as shuffling can be obtained l.

摘要： PURPOSE:To enable for each head to averagely and evenly trace the track section which are simultaneously reproduced in a multaneous simultaneous recording and reproducing system. CONSTITUTION:Heads 26a and 26b, which simultaneously perform recording of single frequency pilot signals, are supplied with signals whose frequencies are plural times changed for every track with repeated patterns. The reproduced pilot signals which are simultaneously reproduced from each head are added by an adder 35, multiplied by a reference signal in a multiplying circuit 38 and a frequency difference component is generated. By this arrangement, the difference signals corresponding to the cross talk pilot signals mixed in the output of each head are extracted by filters 39 and 40, respectively and the respective extracted signals are detected by detectors 41 and 42. The detected outputs are inputted to a differential amplifier 43, a difference is taken and is used as a tracking deviation information.

摘要： PURPOSE:To improve correction ability by multiplexing the additional data for error correction of K bits and correcting the error of transformed bit data based on the additional data. CONSTITUTION:An input signal is inputted through an input buffer circuit 108 to a B parity calculation circuit 109. In this circuit, the error detecting signal of the K bits is calculated, added to (n) bits of video data and turned to the information of the (n+K) bits. Next, a Q parity calculation circuit 110 calculates vertical parity (n+K) bits, and a P parity buffer circuit 111 adds a P parity. The data are transmitted to (n+K)/m transformation circuit 106 and transformed to (m) bit data. In the case of reproducing, the segmented (m) bit data are transformed to the (n+K) bits, and a deshuffling circuit exchanges nc1+Kc2 or nc2+Kc1. Then, the data and the header are separated, a data length and a parity number are extracted and corrected by P and Q correcting circuits, and the correction. ability can be improved.

摘要： PURPOSE:To realize the image recording and reproducing device which can execute both compressed recording and non-compressed recording with comparatively simple circuit scale. CONSTITUTION:An A/D converter 120 quantizes video signals to be inputted. A compressing circuit 130 compresses quantized image data. Anon-compressing circuit 140 thins out the quantized image data. Header preparation circuits 150 and 160 prepare headers containing information concerning the image data to be processed in the compressing circuit 130 and the non-compressing circuit 140. Multiplexing circuits 170 and 180 multiplex the image data processed at the compressing circuit 130 and the non-compressing circuit 140 and the headers outputted from the header preparation circuits 150 and 160 to a prescribed format. A multiplexer 190 selects any one of output signals from the multiplexing circuits 170 and 180 and outputs the selected signal to an encoder circuit 200. The encoder circuit 200 executes recording and modulation. A recording head 210 records the recorded and modulated signals in a recording tape 220.

摘要： PURPOSE:To improve encoding efficiency and to reproduce an image even when a special reproducing is performed. CONSTITUTION:An encoding control circuit 68 controls multiplexers 63 and 67 to multiplex in time division the data for which an intra-image encoding processing I, a forward prediction encoding processing P or a bidirectional prediction encoding processing B, in time division. Of which, I processing flag indicating intra-image encoded data is described in the intra-image encoded data by a subcode preparation circuit 74. At the time of reproducing, by detecting the I processing flag, a speed designation circuit 96 adjusts reproducing speed and reproduces at least the intra-image encoded data without fail. The intra-image encoded data can be decoded only with one frame of data and the reproducing data can be decoded even at the time of special reproducing. Furthermore, an output form conversion circuit 92 outputs the data reproduce and decoded at a certain period corresponding to a specified number of double- speed by means of a timer 103 and thus, the specially reproduced image natual to sight can be obtained.
