Abstract:
1. A method of recording and reproducing video signals received on TV channels with time-division compression and decompression of the video signals to and from a storage medium to allow the video signals to be reproduced while the signals are being recorded, the method comprising the steps of: generating a channel-switching signal when a first TV channel is switched to a second TV channel; obtaining first location information indicating a location of a first distorted video signal from which the first distorted video signal is recorded in the storage medium, the first distorted video signal being received when the channel-switching signal is generated; obtaining second location information indicating a location of a second undistorted video signal from which the second undistorted video signal is recorded in the storage medium, the second undistorted video signal being received when a specific period elapses after the generation of the channel-switching signal; and reproducing the second undistorted video signal from the storage medium while skipping a signal portion of the first distorted video signal recorded in an area of the storage medium, the area existing between locations indicated by the first and the second location information.
