データ再生装置、ディジタルサービスソース装置、および、ディジタルサービスの２つの部分を同期させる方法

摘要

The device has a video processing module (210) to process a part of audiovisual data constituting a part of a digital service coming from a digital set top box (20), and a screen (211) to reproduce an output of parts of the service. The reproduction and processing times of the data introduce a delay into the output of the reproduced data. An extended display identification data EPROM memory (213) informs the box of the introduced delay. Independent claims are also included for the following: (A) a device acting as a digital service source (B) a method for synchronizing two parts of a digital service.
