Claims (9)
- 소스 신호 내 에러를 정정하기 위한 시스템으로서,적어도 하나의 소스 신호 입력(14)과,상기 입력(14)에 전기적으로 연결되고 상기 소스 신호를 디코딩해서 디코드된 신호를 1차 신호 스트림의 생성을 위한 제1 인코더(32)에 보내는 제1 경로와;상기 입력(14)에 전기적으로 연결되며, 인코드된 압축 신호 스트림을 생성하기 위한 제2 인코더(42)를 포함하는 제2 경로와;인코드된 압축 신호 스트림과 상기 1차 신호 스트림을 전송을 위해 결합하는 멀티플렉서(34)를 포함하여,상기 1차 신호 스트림 내의 손실된 데이터가 상기 인코드된 압축 신호 스트림 내의 정보로 수신기에서 대체될 수 있는에러 정정 시스템.
- 제1항에 있어서,상기 소스 신호는 고화질(HD) TV 신호인 에러 정정 시스템.
- 제1항에 있어서,상기 시스템은 약 57㎓와 64㎓ 사이의 스펙트럼에서 적어도 하나의 주파수 상에서 전송하는 에러 정정 시스템.
- 제1항에 있어서,디코드된 소스 신호 데이터의 인코딩을 상기 제2 경로 내의 동일한 소스 신호 데이터의 압축 버전의 인코딩에 대해서 지연하는 상기 제1 경로 내의 적어도 하나의 지연(22)을 포함하는 에러 정정 시스템.
- 제1항에 있어서,송신기에 의해서 보내진 신호를 수신하는 적어도 하나의 수신기를 포함하며, 상기 수신기는,상기 인코드된 압축 신호 스트림으로부터 상기 1차 신호 스트림을 분리하는 디멀티플렉서(128)와,상기 스트림을 처리하는 회로(130, 132, 138, 140, 144, 146)와,제1 에러 컨디션 하에서 상기 1차 신호 스트림으로 전해지는 정보를 디스플레이하고, 다른 경우에는, 상기 인코드된 압축 스트림으로 전해지는 정보를 디스플레이하기 위한 로직(122, 126)을 포함하는 에러 정정 시스템.
- 디스플레이될 무선으로 전송된 데이터의 수신기로서,디스플레이될 데이터를 나타내는 신호- 상기 신호는 적어도 디스플레이될 데이터를 나타내는 제1 신호 및 디스플레이될 데이터를 나타내는 제2 신호를 포함함- 를 처리하기 위한 라디오 신호 처리 컴포넌트(radio signal processing components)(48, 50, 52, 54, 56, 60, 62),상기 제2 신호를 일시적으로 홀딩(holding)하는 지연 컴포넌트(64), 및상기 제1 신호가 에러 컨디션을 위반하는지를 판정하고, 그리고 만약 그렇다면, 상기 제1 신호 내의 에러에 의해 영향받는 정보를 상기 제2 신호로 전해지는 정보로 대체하는 로직(122, 126)을 포함하는 수신기.
- 제6항에 있어서,상기 제1 신호는 소스 신호의 디코드된 버전으로부터 도출되고, 상기 제2 신호는 상기 소스 신호의 압축 버전으로부터 도출되는 것인 수신기.
- 제7항에 있어서,상기 소스 신호는 HDTV 신호인 수신기.
- 제6항에 있어서,상기 수신기는 60㎓ 대역에서 신호를 수신하는 수신기.
