Abstract

Cuando se reproducen datos de AV transmitidos desde un dispositivo de origen mediante transmisión de radio de multidifusión, un dispositivo de sincronización puede verificar el estado de conexión de radio de otro dispositivo de sincronización que reproduzca datos de AV a partir del mismo dispositivo de origen. El dispositivo de sincronización (2a) incluye: una unidad de recepción de AV que recibe datos de AV radiotransmitidos por multidifusión desde el dispositivo de origen (1); una unidad de reproducción que extrae de los datos de AV recibidos, y reproduce datos de AV transmitidos al dispositivo de sincronización (2a); y una unidad de recepción de información de dispositivos que recibe por radio una parte o toda la información de dispositivos de sincronización administrada en el dispositivo de origen (1). La información de dispositivos de sincronización correlaciona identificadores para identificar una pluralidad de dispositivos de sincronización (2a, 2b, ...) que contengan al dispositivo de sincronización (2a) con información de estado que indique el estado de conexión de radio de los dispositivos de sincronización (2a, 2b, ...) respectivos.
