Abstract
An audio-visual system is provided for bringing together a local scene and a remote scene. The audio-visual system includes several concatenated audio-visual modules, and feedback control and control means between the various modules. Each audio-visual module comprises an image sensing device and a sound pickup device of the local scene, and an image and sound recovery device of the remote scene in an image plane. The audio-visual modules are connected to a transmission network. The feedback control and control means ensures image and sound quality continuity on the image plane when the people being filmed or recorded pass in front of the various image and sound pickup devices of the scene concerned.
