Claims

[Scope of utility model registration request]

a receiver 1 side memory unit that stores received character information of teletext broadcasting consisting of character and graphic pattern information or code information;
An operation part 1 for forming and holding desired information consisting of a desired sentence, phrase, figure pattern information, or one code information set by the operation, and the latest character information recorded on the videotape. , - recording side memory sh for storing E,
a comparison unit that compares the received character information 1 if the desired information is present in both the memory units; and an output signal from the comparison unit when the character information j in both memory units do not match; a transfer control section that transfers character information to the recording side memory section and the recording/reproducing main circuit section; At the same time, the character information is transferred from the transfer control section to the recording side memory section by a recording means that records a video signal formed from the received character information into the video track of the video tape. and initial reproduction means for outputting demodulated character information to the recording side memory section.
