Disclosed is a system that permits a variable number of disparate streams of datato be packaged together as content into a single distinct program referred to as anomnimedia package. A framework definition may be specified and created for theomnimedia package to allow a client set top box to decode the information and provideaccess to streams comprising video, audio and metadata information. The frameworkdefinition may be employed by a broadcast system to create a broadcast stream. Amechanism is described that permits a content provider to define a framework for delivering a package of related content. The framework definition encapsulates information necessary to build, format, transmit and display the disparate contentstreams. Data may be downloaded to a receiver prior to the broadcast of an associatedprogram. The present invention may be implemented on terrestrial, cable, satellite, VDSL and other transport systems, including those that support upstream communication. |
