摘要： The audiovisual telecommunication terminal makes it possible to orient the flat screen relative to the position of the face of the operator in front of the same. The terminal comprises means for the flexible driving of the mobile part (20) carrying the flat screen relative to the fixed part (10). The transmission is of the "pulley block" type and uses a motor (12) driving a belt (8) fixed on the one hand to a drive shaft (18) and on the other to the fixed part (10) in order to exert tension on the mobile part (20). The reverse movement can be brought about by helical springs (19).

摘要： An audio-visual telecommunications system comprises a videophone terminal including a videophone communication interface for making a connection to a telecommunications network. A picture processing unit receives audio-visual signals from the videophone terminal which it process in order to compose a picture with sound. The picture processing unit transmits signals representing the composite picture to a television set. The picture processing unit includes an image memory which stores visual signals in a digital form as they are received from the videophone communication interface. A time base receives a composite video signal from the television set and extracts the line and frame synchronized signals. The time base controls a read-out which is synchronized with the extracted synchronization signals and formed responsive to the signals stored in the memory.
