Abstract

Varias aplicaciones proporcionan uno o más de un tiempo de cambio de canal de programación mejorado y/o la calidad general de recepción de televisión con el uso de múltiples canales de transmisión. En una aplicación particular, un primer estrato de la imagen se codifica con el uso del primer nivel de protección de error. El primer estrato codificado tiene un primer retardo de decodificación. Un segundo estrato de la imagen se codifica con el uso del segundo nivel de protección de error. El segundo estrato codificado tiene un segundo retardo de decodificación. El segundo nivel de protección de error es más bajo que el primer nivel de protección de error y el segundo retardo de decodificación es más largo que el segundo retardo de decodificación. Otras aplicaciones proporcionan una estructura de señal que lleva un primer y segundo estratos codificados. Otras aplicaciones decodifican el primer y el segundo estratos codificados.
