Abstract

PURPOSE:To achieve high-precision editing through simple processing without disordering interleave processing by providing a memory for the editing and by establishing an unequivocal relation between data positions on a video signal and addresses of the memory wherein the data are written. CONSTITUTION:An editing memory 12 whose capacity is not less than twice as the number V of data in a vertical synchronizing section wherein an analog signal such as an audio signal is converted into a digital signal on a PCM basis and the digital signal is recorded and reproduced by rotary head type VTRs 17 and 21 is provided. In order to establish an unequivocal relation between write and read addresses of this memory, editing memory address counters 13 and 14 for writing and reading operation which make a round at a period 2V, a register 15, an editing memory 22 with a capacity V, editing memory address counters 23 and 24 for writing and reading operation which make a round at a period V, and a register. Consequently, which position an editing point determined while a reproduced sound after interleaving function is turned off is listened to is equivalent to is found easily, thereby achieving high-precision editing through simple processing.
