Abstract

본 발명은 다채널 오디오신호의 전송 비트열구조에 관한 것이다. 본 발명의 비트열구조도는 헤더정보, CRC부호, 조합정보, 오디오데이타 및 텔레텍스트등과 같은 부가적 데이타부분으로 이루어진다. 헤더정보는 신호의 동기와 특성을 나타내는 부분이며, CRC부호는 오류검출부분이다. 조합정보는 다채널 오디오데이타간의 조합에 관한 정보를 나타내는 부분이며, 오디오데이타는 다채널 오디오데이타가 일정한 순서로 배치되어 있는 부분이다. 오디오데이타부분에서 LFE 채널은 다채널 오디오데이타가 임의의 횟수만큼 배치될 때 마다 1샘플씩 배치되거나 모아서 오디오 데이타부분의 선두에 일괄 배치될 수 있다.The present invention relates to a transmission bit string structure of a multichannel audio signal. The bit string structure diagram of the present invention consists of additional data parts such as header information, CRC code, combination information, audio data and teletext. Header information is a part indicating signal synchronization and characteristics, and CRC code is an error detection part. The combination information is a portion representing information on the combination between the multichannel audio data, and the audio data is the portion in which the multichannel audio data is arranged in a certain order. In the audio data portion, the LFE channel may be arranged by one sample every time the multi-channel audio data is arranged any number of times, or may be collectively arranged at the head of the audio data portion.

따라서, 본 발명에서 새롭게 제안될 다채널 오디오신호의 전송 비트열 구조는 비트열의 효율성을 향상시킬 수 있는 효과를 제공한다.Therefore, the transmission bit string structure of the multi-channel audio signal newly proposed in the present invention provides an effect of improving the efficiency of the bit string.
