Abstract
Transmission of video and audio signals through an integrated services digital network by low-cost means is carried out by a device in the form of a terminal adapter (TA-TV) to which conventional picture and sound recording devices (CAM) and picture and sound reproduction devices (TV) are connected. Device sockets (B, C) to which the picture and sound recording devices (CAM) and picture and sound reproduction devices (TV) are connected are provided on the terminal adapter (TA-TV). A connection with an integrated services digital network (ISDN) is provided via a network socket (A). The terminal adapter (TA-TV) performs an adaptation of the signals to the network.
