Abstract

An outlet for a Local Area Network (LAN), containing an integrated adapter that converts digital data to and from analog video signal. Such an outlet allows using analog video units in a digital data network, eliminating the need for a digital video units or external adapter. The outlet may include a hub that allows connecting both an analog video signal via an adapter, as well as retaining the data network connection, which may be accessed by a network jack. The invention may also be applied to a telephone line-based data networking system. In such an environment, the data networking circuitry as well as the analog video adapters are integrated into a telephone outlet, providing for regular telephone service, analog video connectivity, and data networking as well.
