Abstract

Aspects of the present invention include using a single network identifier for delivering multiple versions of a content object. In some embodiments, a plurality of versions of the content object are created and associated with the single network identifier. When an edge server in a CDN receives a request for the content object, the edge server queries a policy server for a preferred version of the content object to deliver to an end user.

determine a bandwidth capability of the end-user device based on the network-connection data; and

determine the preferred version of the multi-media content object based on the bandwidth capability.

7. The policy server for using the single network identifier to deliver multiple versions of the content object as recited in claim 1, wherein:

the request information comprises a hardware identifier; and

the policy engine is further configured to;

determine a display capability of the end-user device based on the hardware identifier; and

determine the preferred version of the multi-media content object based on the display capability.

8. The policy server for using the single network identifier to deliver multiple versions of the content object as recited in claim 1, wherein the policy engine is configured to:

detect a playback capability of the end-user device; and

direct a protocol transition based on the playback capability.

9. The policy server for using the single network identifier to deliver multiple versions of the content object as recited in claim 8, wherein the protocol transition comprises a transition from HTTP to RTSP (real-time streaming protocol) such that:

the end-user device is redirected via HTTP to an RTSP universal resource locator (URL) in connection with the protocol transition;

or

the policy server directs delivery of an HTML stub file to the end-user device in connection with the protocol transition, the HTML stub file comprising instructions for causing the end-user device to receive RTSP content.

10. The policy server for using the single network identifier to deliver multiple versions of the content object as recited in claim 8, wherein the protocol transition comprises a transition from HTTP to IHS (iPhone HTTP streaming).

11. A method for using a single network identifier to deliver multiple versions of a content object from a content delivery network (CDN) having a plurality of points of presence (POPs) distributed geographically, the method comprising:

receiving, at a merge processor, a notification that a multi-media content object is available for processing;

creating a plurality of versions of the multi-media content object, wherein;

the plurality of versions are created in response to the notification;

the plurality of versions are created prior to receiving a request for the multi-media content object;

each version of the plurality of versions is created with a corresponding encoding profile, from a set of encoding profiles, of the multi-media content object; and

a unique network identifier is associated with the plurality of versions of the multi-media content object;

providing the unique network identifier for delivery to a publisher of the multi-media content object when the plurality of versions of the multi-media content object are available for distribution;

receiving, at a policy server, a query from an edge server of a POP for a version of the plurality of versions of the multi-media content object, wherein;

the query is received in response to the edge server receiving a request from an end-user device for the multi-media content object;

the request from the end-user device includes the unique network identifier; and

the query comprises;

the unique network identifier; and

request information relating to capabilities of the end-user device; and

determining a preferred version of the multi-media content object for distribution to the end-user device by matching the request information to an encoding profile of the set of encoding profiles; and

determining a delivery orchestration scheme to cause the preferred version be sent to the end-user device in response to the request from the end-user device.

12.
