Abstract: PROBLEM TO BE SOLVED: To enable restoring to an adequate state even if recording operation to be finished by both of the recording of main data constituting a data file and the update of control information is interrupted halfway by cut off of a power source and the like. SOLUTION: First, a recording start position is recorded as a control information for a basic recording operation, next, main data is recorded. And last, a recording finish position is recorded as control information. Also, when the main data is recorded, discrimination information by which continuity of recording operation can be discriminated is recorded in each recorded sector. That is, a terminal part of a file can be found by control information about a start point recorded at the time of start of recording and discrimination information of continuity in a real data part even if recording is interrupted and recording control information is not finished.

Abstract: PROBLEM TO BE SOLVED: To realize transfer of ciphered data with a simpler method. SOLUTION: An encoder 1 sequentially adds and converts ASCII codes of each character of file data and a password based on the password. ID set sections 2, 3 provide an ID denoting a couple of data with respect to the converted data and the password, the data are sent to different addresses via paths 7, 10. The received data are given to an ID check section 12, in which the data are discriminated to be a couple of data and the result is fed to a decoder 13. The decoder 13 decodes the converted data based on the received password. Since the converted data and the password are fed to different addresses via separate paths, even when the transfer destination for one data is mistaken, the content of the data is not easily leaked at the transfer destination.

Abstract: PROBLEM TO BE SOLVED: To simplify equipment configuration and processing and to facilitate the transmission of commercial message program in a data transmitter to be used for NVOD. SOLUTION: Partial AV data dividing AV data to be distributed every prescribed reproducing time are repeatedly distributed to respective channels when the data is transmitted. Then, the data are received while successively selecting those channels on the reception side so that the entire AV data can be viewed. Since it is enough for respective channels just to process one part of those AV data, equipment configuration and processing procedure can be simplified for both the transmitter and the receiver. Thus, the commercial message program can be reproduced together with a main program in the reception while being sent through the dedicated channel, the independency of commercial message program is improved and handling is facilitated.

Abstract: PURPOSE: To precisely compensate only a minute fault in an analog signal recording area. CONSTITUTION: When the level of a regenerative signal CA becomes a prescribed level or below, a detection part 12 outputs a detection signal DA. A drive signal RA is generated in a pulse generation part 13 based on the signal DA and a fault detecting signal is recorded making a laser output of a pickup 4 a recording mode. The signal SA in the pulse generation part 15 and the signal NA in the pulse generation part 16 are generated based on the signal DA to be supplied to processing parts 17, 27. The detection operation of the detection part 12 is stopped by the signal TA from the processing part 17 according to the recording mode period. The detection operation of the detection part 22 is stopped for a prescribed period from the recording mode start by the signal TB from the processing part 27. Similarly, also when the signal CB is at a prescribed level or below, the fault detecting signal is recorded. The detection part 22 stops the operation according to the recording mode period, and the detection part 12 stops the operation for a prescribed period from the recording mode start. The operation of the detection parts 12, 22 are stopped in a digital signal recording area based on the signal BT of the pulse generation part 32.
