Abstract
In a broadcasting network, programs are distributed to targeted customer premises equipment. A first program source generates first segments of the program, the first segments having a first identified content. A second program source generates second segments of the program, the second segments having a second identified content. Some of the second segments are generated concurrently to have different second identified content. The segments are transported over the network to the customer premises equipment. While being transported, the segments are selectively merged to form the program. The program having temporally adjacent segments. The signals of the merged first and second segments are synchronized to a common time base, and the selection is responsive to identities of the first and second identified content of the program, and demographics of the network and customer premises equipment.
