Networked mobile EPG service architecture

摘要

A networked mobile EPG system includes an EPG application running on a user device to query and retrieve EPG contents from a home network. A home network gateway uses SIP messaging to allow communication of commands and data on the user device to and from a home networked device through bridging between SIP and a non-SIP protocol of the home network. An EPG service on the home network sends EPG metadata when a query is made from the user device.
