Abstract
PURPOSE: To select channels and indicate channel numbers simultaneously by storing in a memory the channel selection control signal and channel number selection identifying signal.
CONSTITUTION: Digital control signals of receivable channels are written in submemory 2 in the operating area. For selecting channels, a digital control signal corresponding to the address in submemory 2 is read by pushing operating keyboard 1 and the television signal of specified channel is received as an image by D/A converter 3. On the other hand, the selected digital control signal is also applied to logic operation circuit 10, detects a digital signal that coincides with a digital signal in main memory 9 and applies the corresponding channel number indication control signal to channel number indicating device 11. Since the channel number is determined according to the corresponding frequency, the channel number is indicated while the channel is selected.
