摘要： A method and system provide the ability to deliver media content. A packager receives an original encrypted transport stream, and segments the stream into multiple fixed-duration transport stream files (chunks). The packager further generates a manifest file that describes the chunks and is consistent with a hypertext transfer protocol (HTTP) live streaming (HLS) protocol. The manifest file and chunks are delivered to a content delivery network (CDN). An enhanced HLS client is embed in an integrated receiver decoder (IRD). The enhanced HLS client retrieves the manifest file and the chunks from the CDN, and reconstructs the original encrypted transport stream for use by a service provider network.

摘要： Systems and methods for allowing different presentations of a multimedia program, the different presentation delayed relative to each other, by using a delay manifest that includes a sliding window of links to subordinate manifests, and where the subordinate manifests in turn contain links to sequential segments of the multimedia program.
