Abstract

An architecture (system) and method is provided for transcoding codec information to be sent in a Session Initiation Protocol (SIP) signaling stream for rendering rich digital media content. The method is implemented on a computer infrastructure and includes: determining a codec associated with content to be sent to one or more requesting devices; determining that at least one of the one or more requesting devices do not have the codec associated with the content to be sent to the one or more requesting devices; providing codec information to the at least one of the one or more requesting devices; and sending the content to the one or more requesting devices.

First claim

What is claimed is:

1. A method implemented on a computer infrastructure comprising:
determining, by a computing device, that one or more requesting devices have subscribed to receive digital media content from a remote content server, wherein the one or more requesting devices are remote from the computing device;
subscribing, by the computing device, to the digital media content on the content server;
receiving, by the computing device, the digital media content from the remote content server;
determining, by the computing device, a codec associated with the digital media content to be sent to the one or more requesting devices;
determining, by the computing device, that at least one of the one or more requesting devices does not have the codec associated with the digital media content to be sent to the one or more requesting devices based on one or more device profiles of the one or more requesting devices;
determining, by the computing device, using the one or more device profiles of the one or more requesting devices, whether to use a first mode to send the codec associated with the digital media content or use a second mode to send a reference to the codec associated with the digital media content;
in response to determining to use the first mode, sending, by the computing device and through an online network, the codec associated with the digital media content to be sent to the one or more requesting devices, to the at least one of the one or more requesting devices after at least one of the one or more requesting devices is determined to not have the codec so that the at least one of the one or more requesting devices does not need to determine and search for the codec associated with the digital media content;
in response to determining to use the second mode, sending, by the computing device, the reference to the codec to the at least one of the one or more requesting devices via a Session Initiation Protocol (SIP) message; and
sending the digital media content to the one or more requesting devices.

2. The method of claim 1 , wherein the codec is sent by a Session Initiation Protocol (SIP) message online with the content.

3. The method of claim 1 , further comprising sending the codec to the at least one of the one or more requesting devices after receiving a request related to the reference.

4. The method of claim 1 , further comprising retrieving the one or more device profiles from a central repository to determine that the at least one of the one or more requesting devices do not have the codec associated with the content.

5. The method of claim 1 , further comprising generating a charging record for at least one of the content and codec information.

6. The method of claim 1 , further comprising receiving presence information using SIP from the at least one of the one or more requesting devices.

7. The method of claim 1 , wherein the steps are provided on a computing infrastructure which is at least one of maintained, deployed, created and supported by a service provider.

8. The method of claim 1 , wherein the steps are provided on a software component, a hardware component or a combination of the software component and the hardware component.

9. The method of claim 1 , wherein the at least one of the one or more requesting devices dynamically and automatically applies the codec to render the content in the at least one of the one or more requesting devices.

10. The method of claim 1 , further comprising receiving, by the computing device, a new content notification from the content server.
