Abstract

본 발명은 리모콘신호의 코드데이타 검출방법에 관한 것으로, P/S변환부로부터 출력되는 데이타를 1바이트씩 3개의 버퍼(B1, B2, B3)에 각각 저장한 다음, 버퍼 B1, B2, B3에 저장되어 있는 데이타가 ID인가를 각각 체크하여 버퍼 B1에 저장된 데이타가 ID이고, 버퍼 B2에 저장되어 있는 데이타가 ID가 아니며, 버퍼 B3에 저장되어 있는 데이타가 ID이면 버퍼 B2에 저장되어 있는 데이타를 코드데이타로 검출하고, 버퍼 B1에 저장되어 있는 데이타가 ID가 아니고, 버퍼 B2에 저장되어 있는 데이타가 ID이며, 버퍼 B3에 저장되어 있는 데이타가 ID가 아니면 버퍼 B2에 저장되어 있는 데이타를 코드데이타로 검출한다. 또한, 버퍼 B1과 버퍼 B2에 저장되어 있는 데이타가 ID이고, 버퍼 B3에 저장되어 있는 데이타가 ID이면 버퍼 B2에 저장되어 있는 데이타를 코드데이타로 검출하고, 버퍼 B1에 저장되어 있는 데이타가 ID가 아니고, 버퍼 B2와 B3에 저장되어 있는 데이타가 ID이면 버퍼 B2에 저장되어 있는 데이타를 코드데이타로 검출하므로써, 수신장치를 통해 비동기 전송모드로 변환된 리모콘신호 중에 포함되어 있는 코드데이타를 고속으로 정확하게 검출할 수 있도록 한 것이다.The present invention relates to a method for detecting code data of a remote control signal. The data output from the P / S converter is stored in three buffers B1, B2, and B3, one byte at a time, and then stored in the buffers B1, B2, and B3. If the data stored in buffer B1 is ID, if the data stored in buffer B2 is not ID, and the data stored in buffer B3 is ID, the data stored in buffer B2 is checked. If the data stored in the buffer B1 is not an ID and the data stored in the buffer B2 is an ID, and the data stored in the buffer B3 is not an ID, the data stored in the buffer B2 is code data. To be detected. If the data stored in the buffer B1 and the buffer B2 is an ID, and the data stored in the buffer B3 is the ID, the data stored in the buffer B2 is detected as code data, and the data stored in the buffer B1 is the ID. If the data stored in the buffers B2 and B3 is an ID, the data stored in the buffer B2 is detected as code data, so that the code data contained in the remote control signal converted to the asynchronous transmission mode through the receiver can be accurately and quickly. It can be detected.

Claims

In the method for detecting code data included in the remote control signal converted to the asynchronous transmission mode, the remote control signal converted to the asynchronous transmission mode is stored in each of three buffers in units of 1 byte and then stored in the three buffers. A first step of checking whether the existing data is an ID; If the data stored in the first buffer is an ID, the data stored in the second buffer is not an ID, and the data stored in the third buffer is an ID, the data stored in the second buffer is detected as the code data. A second step of doing; A third step of detecting data stored in a third buffer as code data if the data stored in the first buffer among the three buffers is not an ID and the data stored in the third buffer is not an ID; A fourth step of detecting data stored in the second buffer as code data if the data stored in the first buffer and the second buffer is an ID and the data stored in the third buffer is not an ID among the three buffers; ; A fifth step of detecting data stored in the third buffer as code data when the data stored in the first buffer is not an ID and the data stored in the second and third buffers is an ID among the three buffers. Code data detection method of the remote control signal, characterized in that.
