Programming content processing and management system and method
In accordance with aspects of the present invention, a technique is implemented to effectively receive streaming multimedia content in digital form, parse and segment the received transport stream and process the segmented content. Such treatment of received programming content provides for efficient storage of such programming content, and effectively provides for access to such content by administrators of a broadband system as well as users of such systems. In accordance with the invention, a technique enables, among other things: the creation of reference frames for, e.g., effective segmentation of programming content; encapsulation of programming content data as a UDP/IP datagram; associating programming content with provider and dedicated resource attributes; monitoring staging processor activity; effectively segmenting programming content that is scrambled; developing a unicast and multicast; compensating for missing or delayed programming content; and propagating video servers of varying manufacturers.
