KR970068552A - Apparatus and method for performing independent automatic fine tuning (AFT) when viewing another channel while recording in TVCR using a tuner 2 - Google Patents

Abstract

The present invention provides an independent AFT execution device for watching other channels during recording in a TVCR employing a 2-tuner capable of performing AFT on a channel being watched independently of a recording operation of a channel being recorded when viewing another channel during recording. And a method of recording and displaying a received broadcast signal by selectively tuning a plurality of tuners according to remote control data input to remote receiving means and data input through a data input key pad In a video apparatus, when tuning any one of a plurality of tuners to record a broadcast signal and tuning any one of the tuners and inputting channel selection data for viewing the broadcast signal, the tuning data of the viewing channel is automatically Outputs control data for controlling the operation of the peripheral device while outputting fine tuning data And a TV signal processing unit for selecting a signal output from the VCR signal processing unit and a watching broadcast signal according to control data output from the system controller and supplying the video signal and the audio signal to the video output unit and the audio output unit, A first discrimination step of discriminating whether the tuned data of the channel is ATF data when the composite video recording and reproducing device selects an arbitrary channel and reproduces the broadcast signal, A third discriminating step of discriminating whether the system is a recording mode if the tuned data of the AFT is data that has been AFT, and a third discriminating step of discriminating whether the channel is the same as the viewing channel and the recording mode if the recording mode is discriminated in the second discriminating step If the channel of the viewing channel channel recording mode is different from the discrimination result in the third discriminating step, And the tuning data of the viewing channel is an AFT execution step of performing AFT.

Claims (5)

A composite video device for selectively recording a received broadcast signal by selectively tuning a plurality of tuners according to remote control data input to remote receiving means and data input through a data input keypad, When tuner is tuned to record a broadcast signal and channel selection data for viewing a broadcast signal is tuned by tuning any other tuner, the viewing channel outputs data for automatic fine tuning of the tuning data, A system controller for outputting control data and the like for controlling the operation of the VCR signal processing means, and a control means for selecting a signal output from the VCR signal processing means and a watching broadcast signal according to the control data output from the system controller, TV signal processing means for supplying to the output means Wherein the second tuner is used in an independent AFT execution unit when watching another channel during recording in TVCR. A first discrimination step of discriminating whether the tuned data of the channel is AFT data when the composite video recording and reproducing device selects an arbitrary channel and reproduces the broadcast signal in the AFT of the composite video recording and reproducing device having a plurality of tuners A second determination step (S3) of determining whether the system is a recording mode if the tuned data of the channel selected in the first determination step is AFT data; and a second determination step (S3) (S4) for determining whether the channel of the recording channel is the same as the channel of the recording mode, and if the channel of the viewing channel is different from the channel of the recording mode in the third discriminating step, The data is subjected to AFT execution step (S5) for performing AFT. Independent AFT execution method at the time of watching another channel during recording in TVCR employing 2 tuner. 3. The tuner according to claim 2, wherein the first discrimination step comprises an operation branch (S6) of keeping the current tuning data as it is when the tuning data of the channel being watched is not AFT- Independent AFT execution method when viewing another channel while recording in adopted TVCR. 3. The method according to claim 2, wherein, in the second determination step, when the recording is not proceeding on an arbitrary channel, the operation branch (S7) for changing the tuning data of the currently watched channel to the tuning data corrected by the AFT and then terminating The method of independent AFT execution when watching another channel during recording in TVCR employing the 2 tuner. 3. The method of claim 2, wherein, in the third determination step, when the channel data is the same as the currently watched channel data in the state where recording is proceeding on an arbitrary channel, the tuning data of the channel currently being watched is tuned by the AFT And an operation branch (S7) for ending the change and ending the operation. The independent AFT execution method at the time of watching another channel during recording in the TVCR employing the 2 tuner. ※ Note: It is disclosed by the contents of the first application.
