Abstract
A system for providing multicast distribution of incrementally enhanced content is disclosed. The system may include encoding content by utilizing an incremental layer encoding algorithm to generate a low resolution base stream for content and one or more incremental streams for the content. The incremental streams may each have higher resolutions than the base stream. The system may provide the base streams and one or more of the incremental streams to a client device based on available bandwidth and based on the capabilities of the client device. Each of the streams of content may be provided to the client device by having the client device connect to one or more multicast sessions. As the streams are accessed by the client device, the client device may combine and decode the base streams, along with any accessed incremental streams, to obtain the content at an available resolution.
