Abstract

본 발명은 VCR의 ATCS(Automatic TV Channel Setting)에 관한 것으로, 특히 VCR에서 코드를 발사한 후 다시 수신하여 비교하는 ATCS 셀프 테스트를 수행하여 VCR 배치가 제대로 되었는지, TV 메이커 선택이 제대로 되었는지를 유저에게 알려줌으로써, VCR에서 TV로 송신하는 채널전환 명령코드가 TV에 정확히 수신되도록 하고, 또한, 일정시간 동안의 지연없이 유저가 리모콘 사용을 종료하면 즉시 채널전환 명령코드를 송신하므로 TV를 빠르게 조정할 수 있게 되며, 유저가 리모콘을사용하고 있거나 재생키를 계속 누르고 있다면 채널전환 명령코드를 송신하지 않고 유저의 리모콘 사용이나 재생키 누름이 끝난 것을 감지하여 송신하므로 리모콘 신호와 ATCS 신호의 충돌을 막아 TV를 정확하게 조작할 수 있다.The present invention relates to ATCS (Automatic TV Channel Setting) of a VCR, and in particular, the ATCR self-test is performed by comparing the code after the code is fired from the VCR to perform the ATCS self-test. This function ensures that the channel switching command code transmitted from the VCR to the TV is correctly received by the TV. Also, the channel switching command code is transmitted immediately after the user finishes using the remote control without delay for a certain period of time so that the TV can be quickly adjusted. If the user is using the remote control or keep pressing the play key, it detects the end of the user's use of the remote control or presses the play key without transmitting the channel change command code. I can operate it.

Claims

When a certain key is input by the user, VCR sends the specific code to the TV, and the TV retransmits the received code to the VCR as it is, and then compares the transmission code and the reception code to the user to confirm that the transmission and reception are correct. The automatic channel setting method of the VCR, which comprises a first self-testing process for notifying and a channel switching process for automatically switching channels of a TV by transmitting a channel switching command code to a TV when a play-related command is input.

The method of claim 1, wherein when the channel switching process is performed, it is determined whether the channel switching command code transmitted to the TV is re-received to the VCR, and a corresponding message is displayed to determine whether the channel switching command code transmission / reception function between the VCR and the TV is performed properly. And a second self test procedure for notifying a user.

The method of claim 1, wherein the VCR is automatically displayed according to a result of comparing the transmission code with the reception code.

The channel switching process of claim 1, wherein, when the play key is input, the channel switching process continues receiving until the press of the play key is stopped, and when the press of the play key is stopped, the channel switching command code is transmitted to the TV. VCR automatic channel setting method.

A first step of determining whether a signal other than the channel switching command is received by the receiving unit of the VCR when a channel switching command signal is input by a user's key input; and receiving the signal when the signal other than the channel switching command is received. And a second step of transmitting the channel switching command signal after a predetermined time delay until it does not occur.

※ Note: The disclosure is based on the initial application.
