Abstract

A system for providing information content over a network to a mobile communication device includes a transcoding system and a first network device. The transcoding system includes a plurality of transcoders. Each transcoder is operable to transcode the information content from a respective input content type into a respective output content type. The first network device is in communication with the transcoding system and includes a connection handler system. The first network device is operable to receive a first connection request that includes transcoder request data and to select a corresponding connection handler. The connection handler is operable to select one or more transcoders from the plurality of transcoders based on the transcoder request data.

Claims20

Dependent claims

A system for providing data access between an information source and a mobile communication device, the system comprising:

a transcoding system comprising a first storage medium containing a plurality of processor executable transcoders, each transcoder executable to transcode information content from a respective first content type into a respective second content type;
and
a first network device physically located at a location remote from the transcoding system, the first network device comprising a connection handler system, the connection handler system operable to receive connection data for a connection between the information source and the mobile communication device and to select a corresponding connection handler from a plurality of connection handlers, wherein each connection handler is specific for a particular communication protocol, the selected connection handler operable to transmit information content received from the information source to the transcoding system and operable to specify to the transcoding system one or more transcoders from the plurality of transcoders to use to transcode the information content, the selected connection handler further operable to receive transcoded information content from the transcoding system and to send the transcoded information content to the mobile communication device.

A method for providing remote data access to a mobile communication device, comprising the steps of:

receiving a connection request at a first location and selecting one of a plurality of connection handlers based on the connection request;
establishing a connection with an information source responsive to the connection request using the selected connection handler, wherein each of the plurality of connection handlers is specific for a particular communication protocol;
receiving information content from the information source via the selected connection handler;
selecting via the selected connection handler one or more transcoders associated with an identifier of the mobile communication device, each transcoder being configured to transcode information content from a respective input content type into a respective output content type;
retrieving the one or more transcoders from a storage medium at a second location over a network;
transcoding the information content at the first location using the retrieved one or more transcoders to create transcoded information content;
and
forwarding via the selected connection handler the transcoded information content to the mobile communication device.
