Abstract

Abstract Channel selecting operation of a tuner is controlled by a VTR microprocessor. A broadcasting station code detected by a broadcasting station code detector 4 from an output video signal SV from the tuner is supplied to the VTR microprocessor. To the VTR microprocessor, there are connected a first memory which stores, in advance, data representing the corresponding relationship between broadcasting station codes and VCR+ guide channels, and a second memory which stores data representing the corresponding relationship between channels selectable by the tuner and the VCR+ guide channels. When an automatic setting key on a remote control commander or a key input circuit is pressed, the VTR microprocessor controls the tuner to select channels successively, reads VCR+ guide channels corresponding to the broadcasting station codes detected by the broadcasting station code detector from the first memory, and writes the VCR+ guide channels in the second memory in relation to the channels selected by the tuner.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 91 words
A recording apparatus comprising: broadcasting station code detecting means for detecting first broadcasting station codes from television broadcast signals of channels selectable by a tuner; memory means for storing data representing the corresponding relationship between second broadcasting station codes and the first broadcasting station codes; and processing means for setting data representing the corresponding relationship between the channels selectable by the tuner and the second broadcasting station codes by using the first broadcasting station codes detected by said broadcasting station code detecting means and the data stored in said memory means.
Claim 2
Dependent Claim 21 words
A recording apparatus according to claim 1, further comprising: second memory means for storing the data set by said processing means.
Claim 3
Dependent Claim 127 words
A recording apparatus comprising a remotely controllable recorder and a remote control transmitter for remotely controlling the recorder; said recorder comprising: broadcasting station code detecting means for detecting first broadcasting station codes from television broadcast signals of channels selectable by a tuner; first memory means for storing data representing the corresponding relationship between second broadcasting station codes and the first broadcasting station codes; and processing means for setting data representing the corresponding relationship between the channels selectable by the tuner and the second broadcasting station codes by using the first broadcasting station codes detected by said broadcasting station code detecting means and the data stored in said first memory means; said remote control transmitter having: second memory means for storing the data set by said processing means.
