Abstract
Video telephony is implemented via a set-top box located at each participating party'"'"'s site, a number of media gateways located at one or more cable TV distribution hubs or headends, and a number of software switches located at one or more headends and/or within the Internet or a managed data network. The set-top box provides an interface for a participating party to send and receive voice, video, and data converged transmissions. The media gateway is designed to handle both in-band (media) and out-of-band (call signaling) transmissions, and comprises a switching core that directs the out-of-band transmissions to the software switch. The software switch manages all out-of-band signaling and controls the operation of the media gateway.
