Abstract: front page image
(EN)The present invention relates to an apparatus and method for providing each subscriber with a different A/V (audio/video) stream for a single program in a digital cable broadcast environment. More particularly, the apparatus comprises: means for generating multi-screen information on the basis of the relationship between a single program and a plurality of A/V streams in the event the plurality of A/V streams exist for the same TV program; means for receiving multi-screen information; means for regenerating, from the multiplexed stream containing the plurality of A/V streams, a stream for a multi-screen service containing individual A/V streams; means for checking the bandwidth of the stream for the multi-screen service transmitted through a modulator, and a program number; communication means for checking the subscriber through a return channel, and informing a subscriber terminal of the bandwidth for transmitting the stream for the multi-screen service selected by the subscriber and the program number; and means for transmitting the stream, containing the A/V stream corresponding to the screen selected by the subscriber, for the multi-screen service.
(FR)La présente invention porte sur un appareil et un procédé de fourniture à chaque abonné d'un flux A/V (audio/vidéo) différent pour un même programme dans un environnement de câblodistribution numérique. En particulier, l'appareil comprend : un moyen pour générer des informations multi-écrans sur la base de la relation entre un programme individuel et une pluralité de flux A/V dans le cas où la pluralité de flux A/V existent pour le même programme de télévision ; un moyen pour recevoir des informations multi-écrans ; un moyen pour régénérer, à partir du flux multiplexé contenant la pluralité de flux A/V, un flux pour un service multi-écrans contenant des flux A/V individuels ; un moyen pour vérifier la bande passante du flux pour le service multi-écrans transmis par l'intermédiaire d'un modulateur, et un numéro de programme ; un moyen de communication pour vérifier l'abonné par l'intermédiaire d'un canal retour, et indiquer à un terminal d'abonné la bande passante pour transmettre le flux pour le service multi-écrans sélectionné par l'abonné et le numéro de programme ; et un moyen pour envoyer le flux, contenant le flux A/V correspondant à l'écran sélectionné par l'abonné, pour le service multi-écrans.
(KO)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.
