Abstract
(KO)
소정의 광전 변환 특성을 부여한 복수 종류의 전송 비디오 데이터를 전환해서 송신하는 경우, 수신측에 있어서 전송 비디오 데이터로부터 표시용 화상 데이터를 얻는 처리를 적절하게 행할 수 있도록 한다. 소정의 광전 변환 특성을 부여한 복수 종류의 전송 비디오 데이터를 전환해서 얻어지는 전송 비디오 데이터에 인코드 처리를 실시해서 비디오 스트림을 얻는다. 이 비디오 스트림을 포함하는 소정 포맷의 컨테이너를 송신한다. 컨테이너에, 이 컨테이너에 포함되는 비디오 스트림이 갖는 전송 비디오 데이터의 종류를 나타내는 식별 정보를, 전환 타이밍보다 소정의 시간량 이상만큼 전의 타이밍으로부터 전환 후의 전송 비디오 데이터의 종류를 나타내도록 삽입한다.
