A videoconferencing system includes a camera, a microphone, and an interface module. The module is coupled a modem connected to a television network and is coupled to a television set and a set-top box. The module decodes encoded audio video signals received from the modem that are part of a videoconferencing session. The module also encodes audio and video signals received from the camera and the microphone and sends the encoded audio video signals to the modem to be part of the videoconferencing session. The module can selectively send decoded audio signals to the television set or can selectively send video received from the set-top box to the television display. In addition, the module can send compressed audio and video signals received from the microphone and camera to the set-top box for processing and delivery to the television display.
