Claims (5)
- 24Hz의 프레임레이트로 부호화된 비트스트림을 60Hz의 필드주파수에 따라 디스플레이하기 위해 복호화측의 버퍼점유량을 제어하는 방법에 있어서, 복호화측버퍼에 기설정된 초기지연구간이 경과직후, 소정 구간동안 복호화측의 버퍼에 소정 비트를 추가로 삽입하는 단계와; 상기 비트삽입에 의해 복호화측의 버퍼가 오버플로우를 일으키는 것을 방지하기 위해 소정 크기로 버퍼용량을 확장하는 단계를 포함하는 것을 특징으로 하는 복호화측의 버퍼점유량 제어방법.
- 제1항에 있어서, 상기 비트삽입단계는 60Hz의 필드주파수에 따라 디코딩할 경우 복호화측버퍼가 언더플로우현상을 일으키지 않도록 추가로 삽입하려는 비트량을 산출하는 단계를 포함하는 것을 특징으로 하는 복호화측의 버퍼점유량 제어방법.
- 제2항에 있어서, 상기 비트량산출단계는 아래의 계산식에 의해 비트량을 산출하는 것을 특징으로 하는 복호화측의 버퍼점유량 제어방법.T = (시스템클럭)×(연장구간)[고정레이트로 입력되는 비트량]여기서, T는 추가된 비트량이다.
- 제1항에 있어서, 상기 버퍼용량확장단계는 비트삽입단계에서 삽입하는 비트량에 상응하는 확장분만큼의 버퍼용량을 산출하는 단계를 포함하는 것을 특징으로 하는 복호화측의 버퍼점유량 제어방법.
- 제4항에 있어서, 상기 버퍼용량산출단계는 아래의 계산식에 의해 정의되는 것을 특징으로 하는 복호화측의 버퍼점유량 제어방법.확장된 버퍼용량 = (전송비트율)×(연장구간)여기서, 전송비트율은 버퍼에 입력되는 비트레이트[비트/sec]※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
