Abstract

본 발명은 채널 메모리에 관한 것으로 특히 TV, VCR 리모콘 등으로 수신되는 채널을 메모리에 자동으로 저장시켜 주는 채널 자동 저장 방법에 관한 것이다.The present invention relates to a channel memory, and more particularly, to a channel automatic storage method for automatically storing a channel received by a TV, a VCR remote controller, or the like in a memory.

그러나 종래 채널에 메모리 시스템은 각 어드레스 별로 하나하나 메모리(31)에 저장시켜야 하며 각 어드레스에 저장된 채널을 확인시 어느 어드레스에 몇번의 채널이 기억되어 있는지 판단하기 어렵다는 문제점이 있다.However, in the conventional channel, the memory system has to store the memory 31 one by one for each address, and it is difficult to determine how many channels are stored at which address when checking the channel stored at each address.

본 발명은 마이콤(30)에서 영상 신호의 동기에 따라 진행되는 동기 처리단계(S10)와 인가된 채널 번호를 기준된 번호에 따라 처리하는 기준 처리단계(S20)와 마이콤(30)에서 메모리(31)에 채널번호를 레지스터에 저장시켰다가 메모리(31)의 어드레스에 기억시키는 저장단계(S30)와 채널 번호를 상승시키는 단계(S40)로 구성하여 전압에 의한 VS(Voltage Synthesize)방식과 주파수에 의한 FS(Frequency Synthesize)방식에 모두 적용할 수 있으며 TV, VCR, 리모콘 등으로 수신되는 채널을 메모리(31)에 자동으로 각 어드레스에 확인가능하게 저장시켜 줄 수 있는 매우 유용한 발명이다.The present invention is a synchronization processing step (S10) proceeds in accordance with the synchronization of the image signal in the microcomputer 30 and the reference processing step (S20) for processing the applied channel number in accordance with the reference number and the memory 31 in the microcomputer 30 (S30) storing the channel number in a register and storing it in the address of the memory 31, and raising the channel number (S40). The present invention can be applied to both FS (Frequency Synthesize) methods and is a very useful invention that can automatically store the channels received by TV, VCR, remote controller, etc. in the memory 31 at each address.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 일반적인 채널 메모리 시스템의 구성도.1 is a block diagram of a general channel memory system.

제2도는 본 발명 채널 자동 저장 방법의 동작 흐름도.2 is an operation flowchart of a channel automatic storage method of the present invention.

Claims

The synchronization processing step S10 proceeds according to the synchronization of the image signal in the microcomputer 30 and the reference processing step S20 for processing the applied channel number according to the reference number and the channel in the memory 31 in the microcomputer 30. And a storage step (S30) of storing the number in a register and storing it in an address of the memory (31) and raising the channel number (S40).

According to claim 1, wherein the synchronization processing step (S20) is a synchronization determination step (S11) to determine whether the video signal is synchronized from the image processing unit 20 to the horizontal synchronization terminal of the microcomputer 30 and the image signal is applied to the horizontal synchronization terminal. Increasing the channel number according to non-synchronization (S12) and comparing the latest channel number with the rising channel number (S13).

The method according to claim 1 or 2, wherein the reference processing step (S20) compares whether the corresponding channel number is less than or equal to 12 as the video signal is synchronized in the synchronization processing step (S11) (S21) and the channel number. Is searched for the register according to not less than or equal to 12 (S22) and the step of checking whether the register is empty (S23) and the step of checking whether the register is the maximum according to the non-empty register (S24). Channel auto-save method characterized in that.
