ABSTRACT
Now that the digital television (DTV) era has arrived, most broadcasters and facility operators have to deal with several different television formats. In the analog to digital transition, video transport mechanisms improved while image formats stayed largely the same. In the DTV era, transport mechanisms continue to evolve, but now the image formats in almost every facility vary in line rate and often in frame rate as well. Preserving image integrity in this multiformat environment presents a unique challenge for the television engineer.
