ABSTRACT
The performance of a film-based motion picture system in one location in the world is generally the same as in any other location; thus, international exchange of film programming is relatively straightforward. This is not the case, however, with analog broadcast color television systems. The lack of compatibility has its origins in many factors, such as constraints in communications channel allocations and techniques, differences in local power source characteristics, network requirements, pickup and display technology, and political considerations relating to international telecommunications agreements.
