摘要

In course of the main service, information associating a second service to the main service is broadcast. In a further stage a second service broadcasts groups of images, these being from the same group originating the audio visual sources (CAM1-CAM4). Independent claims are included for a broadcasting center for audiovisual outputs, a registration facility associating the data, and a method and device for visualizing the audiovisual transmission.
