Abstract

Se proporciona un método para sincronizar corrientes de video de Tasa de Bits Adaptable (ABR) creadas desde una sola señal de video de banda base que es distribuida a través de múltiples líneas de transmisión coaxial de diferente longitud a diferentes codificadores de video; el método inserta un marcador en la señal de banda base de la Interfaz Digital Serial (SDI); la señal de banda base entonces es dividida con los marcadores regulares insertados y es distribuida a codificadores sobre líneas de transmisión coaxial de diferente longitud; la sincronización del video de banda base entonces puede ser ejecutada utilizando receptores de banda base proporcionados con los diferentes codificadores; un marcador puede ser de marca propia o se puede basar en normas de temporización para SDI tales como un código de tiempo de intervalo vertical (VITC).
