Abstract
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.
Claims38
A networked mobile EPG system, comprising:
- an EPG application running on a user device to query and retrieve EPG contents from a home network;
- a home network gateway using 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;
- and
- an EPG service on the home network to send EPG metadata when a query is made from the user device.
A portable device for use with a networked mobile EPG system, the device comprising:
- one or more applications with graphical user interface components adapted to send EPG requests to a home network via SIP and display EPG contents received form the home network via SIP;
- a wireless interface for communicating with a SIP enabled network;
- and
- a network stack enabling said device to communicate with the home network via SIP protocol, therefore acting as a SIP UA (user agent) from the SIP network perspective.
A home network for use with a mobile EPG system, the network comprising:
- a home network gateway using SIP messaging to allow communication of commands and data on a user device to and from a home networked device through bridging between SIP and a non-SIP protocol of the home network;
- and
- an EPG service on the home network to send EPG metadata when a query is made from the user device.
