System and method for video delivery over heterogeneous networks with scalable video coding for multiple subscriber tiers

摘要

A method is provided in one example and can include receiving a source data stream, generating a base layer sub-stream from the source data stream, and generating an enhancement layer sub-stream from the source data stream. The method further includes communicating the base layer sub-stream to a client device using a first communication protocol, and communicating the enhancement layer sub-stream to the client device using a second communication protocol. In a particular example, the one-to-many communication protocol is a multicast communication protocol and the second communication protocol is a unicast communication protocol. In another example, the base layer sub-stream is sent to the client device via a first network connection and the enhancement layer sub-stream is sent to the client device via a second network connection.

1. A method, comprising:
receiving a source data stream; generating a base layer sub-stream from the source data stream; generating an enhancement layer sub-stream from the source data stream; communicating the base layer sub-stream to the client device using a first communication protocol, wherein the first communication protocol is one-to-many communication protocol; receiving a subscription request from the client device during the communicating of the base layer sub-stream to the client device, the subscription request indicative of a selection by a user associated with the client device to subscribe to the enhancement layer sub-stream; and communicating the enhancement layer sub-stream to the client device during the communicating of the base layer sub-stream using a second communication protocol responsive to the subscription request being indicative of the selection by the user to subscribe to the enhancement layer sub-stream, wherein the second communication protocol is a one-to-one communication protocol.
