Program Substitution

Program substitution is a form of digital program insertion (DPI) that offers the ability to splice secondary, long-format video content into a primary video stream. This capability is particularly important for some operators in meeting national program-
ming content rules which often limit the amount of foreign programming that is allowed. For example, a channel airing a foreign music video network from 10 a.m. to 6 p.m. may be required to switch to local programming during the prime time evening hours. This capability is equally important for channels that play long-form infomercials or home shopping programs during the early morning hours, but need to switch to their regular programming for the remainder of the day. 

Both RGB's Broadcast Network Processor (BNP) and Video Multiprocessing Gateway (VMG) have the ability to seamlessly switch between programs on a single output channel, ensuring frame-accurate switching to avoid clipping of the programming, as well as switching programs on a pre-determined schedule.
