Abstract
A video tape recorder capable of reproducing a video tape on which a character multiplex signal is recorded. In the video tape recorder, when a video tape recorder unit reproduces the video tape, a character signal generator generates a character display signal based on the character multiplex signal. When the video tape recorder unit is transferred from the reproduction operation to a pause operation, the character signal generator continues generating the character display signal which has been generated immediately before the transfer to the pause operation.
Claims4
A video tape recorder with a function of controlling a character display, comprising:
- a video tape recorder unit for reproducing a video tape on which a character multiplex signal is recorded;
- a character signal generator including a memory for generating a character display signal based on character codes decoded from the character multiplex signal and stored in said memory during reproduction of said video tape, said character signal generator being arranged to prevent generation of said character display signal in response to a control code which is output when said character codes are not decoded from said character multiplex signal;
- and
- a control unit which, when said video tape recorder unit is transferred from a reproduction operation to a pause operation, prevents said control code from being output and thereby causes said character signal generator to continue to generate a character display signal based on said character codes stored in said memory immediately before the change to the pause operation, whereby display of characters detected in said character multiplex signal is carried out during the pause operation without employing a caption memory for storage and recall of the character display signal.
