Abstract: PROBLEM TO BE SOLVED: To prevent a discordant sound from being generated at a connection part by connecting discontinuous voice signals in a time base direction, changing voice levels before and after a connection part, adjusting voice levels according to the amplitude level difference before and after the connection part and writing the connected voice signals on a recording medium to enable the connecting of voice signals while reducing the missing of information. SOLUTION: A voice signal processing part 12 connects timewisely discontinuous voice signals by converting a voice signal to be inputted from an analog signal into a digital signal in an A/D converter circuit 15 and by temporarily storing the voice signal outputted by the circuit 15 in a voice buffer 16. Moreover, the part 12 changes voice levels before and after the connection part of the voice signals by applying a fading processing with respect to a voice signal to be outputted by the voice buffer 16 by a fading processing circuit 17. Moreover, the buffer 16 controls the writing and the reading of data by a control signal from a control circuit.

Abstract: PROBLEM TO BE SOLVED: To prevent an underflow and an overflow from being generated by providing recording areas for a recording system and for a reproduction system and an integrated storage means making assignments of respective storage areas variable and controlling assigning of integrated storage areas according to a desired recording and/or a desired reproduction mode to simplify a hardware constitution. SOLUTION: An integrated buffer memory 22 is arranged at the back of a band of video signal compression processing part 21 and the front of a band of video signal expansion processing part 31. When the generation amount of a signal from the band of video signal compression processing part 21 is increased at the time of recording and the waiting time of an optical disk drive 1 is large, an overflow is avoided by diverting a memory area for a reproduction system 22b to the purpose of a memory area for a recording system 22a by the control of a system controller 5. Moreover, at the time of reproduction, when frequencies of seeks and jumps are numerous, an underflow is avoided by diverting the memory area for the recording system 22a to the purpose of the memory area for the reproduction system 22b.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device capable of recording and reproduction signals of an unfixed data quantity to and from a recording medium of a prescribed recording capacity for the longest possible time. SOLUTION: The video signals and sound signals respectively inputted from input terminals 1, 2, are compressed by a signal compression circuit 3. A controller 4 changes the compression rates of the signals under recording according to the empty capacity of the recording medium 100 detected by a residual capacity detecting circuit 5. The compressed video signals and sound signals are added with the compression control signals including the compression rate information indicating these compression rates as part of sub-codes in a recorded signal processing circuit 6 and are recorded on the recording medium 100. At the time of reproduction, the video signals and sound signals read out of the recording medium 100 are expanded by the expansion rate determined from the compression control signals described above. The device may be so constituted that the compression rates may be changed according to the lapse of time of the signal recording to the recording medium 100.
