Abstract: 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.

Abstract: 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.

Abstract: A method of distributing video program material, includes receiving a first multi-program transport stream (MPTS) containing multiple video services and distribution constraint data specifying at least one of the video services, and creating a second transport stream that contains at least the specified video service and complies with at least one constraint specified in the distribution constraint.

Abstract: A method is provided for delivering alternative programming to subscribers. The method includes receiving from a satellite an RF signal in which a first program to be blacked out is carried on a first channel. The method also includes tuning to the first channel and extracting therefrom a first digital transport stream. A replacement program is received in a second digital transport stream. The first and second digital transport streams are decoded to produce first and second video outputs, respectively. The first video output is delivered to subscriber terminals over a content distribution system. When the first program is to be blacked out, the second video output is delivered to the subscriber terminals over the content distribution system instead of the first video output.
