ITU-T J.112 Annex A (03/2001)

Difusión de vídeo digital: Canal de interacción para sistemas de distribución de televisión por cable en difusión de vídeo digital

El presente anexo es la especificación fundamental para la provisión del canal de interacción en las redes de televisión por cable.No tiene por objeto especificar una solución basada en un canal de retorno asociado a cada sistema de radiodifusión porque se desea conseguir la interoperabilidad de diferentes medios de entrega para el transporte del canal de retorno.Las soluciones proporcionadas en el presente anexo forman parte de un conjunto más amplio de alternativas de implementación de servicios interactivos para sistemas de radiodifusión de vídeo digital (DVD).
