摘要： A support method for helping the user find a desired program from a collection of recorded television programs easily and quickly, and a recording/reproducing apparatus using this method. The recorded program viewing support system, when recording a television program, records electronic program information on the program, classifies the electronic program information according to predefined program category criteria, and successfully assigns predefined category numbers (recording channels) to the program to be recorded. Before the user views a recorded program, the user specifies the number of the recorded channel. A recorded channel number is allocated with a category item and hence the user can easily know the contents of the recorded programs. The user can change the channel number successively or directly specify it by using a remote controller to find a desired program easily and quickly. When disk media such as HDD and DVD-RAM are used as a storage in particular, the recorded programs can be randomly accessed allowing the user to zap through recorded programs.

摘要： A recording/reproducing apparatus is provided for effecting digital processing to convert an analog video signal into a digital signal without losing character data superimposed over a vertical blanking period of the analog video signal. The recording/reproducing apparatus for converting the analog video signal into the digital signal and recording/reproducing the converted digital signal has a detector which detects character data, which is superimposed over the vertical blanking period of the received analog video signal, at the recording time. A superimposer which encodes the detected character data and superimposes the encoded character data over a digital signal from which the character data was removed, whereby the digital signal with the superimposed character data is recorded on the recording media. There is also a detector which detects first copy guard data superimposed over the vertical blanking period and second copy guard data superimposed over a color burst signal; and an adder which adds the two detected copy guard data to a signal reproduced from the recording media.
