Abstract

PURPOSE:To prevent the misoperation of a subscriber by overlapping a character and a graphic indicating the operation of a CATV home terminal on a received and channel selected video and displaying. CONSTITUTION:The key operation of the CATV home terminal a command from a center is analyzed to output data to an on screen display part 6 by a microprocessor 3. The on screen display part 6 inputs synchronizing signal data from a synchronizing and separating part 5 and outputs the video of the character and the graphic in addition to a video signal output part 7. The command from the center is demodulated in a data demodulating part 9 via a wave divider 1. The microprocessor 3 analyzes the demodulated command from the center and outputs the result thereof to the on screen display part 6. The output of a tuner 2 is detected in a video and sound detecting part 4 and outputted to the video signal output part 7 and a sound signal output part 8.

す。The duplexer l transmits video and data from the center in a predetermined direction. The tuner 2 selects the video signal from the branching filter 1 based on data from the microprocessor 3. The output of the tuner 2 is detected by a video/audio detection section 4 and output to a video signal output section 7 and an audio signal output section 8. Further, the video signal detected by the video/audio detection section 4 is input to the synchronization separation section 5, and the synchronization separation section 5 generates the timing of the synchronization signal.
