Document Type and Number:
Japanese Patent JP2952200
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To excellently record and reproduce a 1st image signal and a 2nd image signal whose interpolation amount differs from each other by varying the size of interleaving area so as to obtain optimum interleave result depending on a recorded signal. SOLUTION: In the case of recording in the standard mode, an analog video signal is decoded by applying output data from a synthesis circuit 39 to a D/A converter 41 as they are via a terminal C of a switch 40. In the case of a signal recorded by the double speed mode, after data block-coded by a block decoding circuit 43 are restored to original data, the resulting data are fed to a D/A converter 41 via a terminal B of the switch 40. In the case of a signal recorded in the 4-multiple mode, the data are fed to a block decoding circuit 44, in which field data subject to de-framing are decoded and the resulting data are fed to a D/A converter 42 via a terminal A of the switch 40. The interleaving area size is changed in this way to obtain optimum interleaving in response to the signal to be recorded.
