<p>PURPOSE:To record a program surely and accurately despite of changing of a program by turning on a power supply and recording the program by the frame record retrieval control circuit when a broadcasting frame code in a received broadcasting signal coincides with a reserved frame code in the memory. CONSTITUTION:A radio wave received by the antenna 1 is inputted to the tuners 2 and 11, a signal of intermediate frequency is inputted to the video recording section 4 from the tuner 2, and it is converted into a composite video signal and a sound signal. On the other hand, the signal of intermediate frequency from the tuner 11 is inputted to the control circuit 12, and a frame code is extracted. When the extracted frame code coincides with a frame code of reserved video recording information previously stored in the memory 6 for reserved video recording information, the circuit 12 turns on the main power supply 9 and commands video recording to the recording control circuit 3. The circuit 3 set the tuner 2 to the channel desired to record and commands video recording to the video recording section 4. The tuner 11 retrieves the reserved channel frame code even during reserved video recording, and commands the end of video recording to the circuit 3 when the reserved broadcasting part is completed.</p> |
