Abstract

본 발명은 디지털 케이블 방송 환경에서 하나의 편성에 대해 가입자별로 각기 다른 A/V (오디오/비디오) 스트림을 제공하는 장치 및 방법에 관한 것이다. 보다 상세하게는 동일한 TV 편성에 대해 복수의 A/V 스트림이 존재할 경우 하나의 편성과 복수의 A/V 스트림 사이의 관계에 기반하여 다화면 정보를 생성하는 수단; 다화면 정보를 수신하는 수단, 복수의 A/V 스트림을 포함한 다중화된 스트림으로부터 개별 A/V 스트림을 포함하는 다화면 서비스용 스트림을 재생성하는 수단; 변조기를 통해 송출되는 다화면 서비스용 스트림의 대역폭과 프로그램 번호를 확인하는 수단; 리턴 채널을 통해 가입자를 확인하고 가입자가 선택한 다화면 서비스용 스트림이 송출되는 대역폭과 프로그램 번호를 가입자의 단말기로 알려주는 통신 수단; 및 가입자가 선택한 화면에 해당하는 A/V 스트림이 포함된 다화면 서비스용 스트림을 송출하는 수단을 포함한다.
