Video broadcasting is moving towards all digital technology as higher quality video and more bandwidth efficiency become available in digital broadcast systems (although the analog TV systems will co-exist with digital TV systems for years to come). There are many different digital TV standards across the world, categorized as cable, satellite, terrestrial or mobile TV. More and more, set-top boxes (STB) and TV sets require integration of multiple digital broadcast standards such as DVB-T/H, ISDB-T, DTMB and ATSC for worldwide markets. And mobile TV is hot. Developers and manufacturers of mobile phones nowadays are faced with integrating DVB-H and ISDB-T mobile TV broadcasting technology into their devices. This requires test equipment and test procedures different from those required for mobile cellular communications.
Objective BER measurement and subjective video clips are necessary for video receiver evaluation. ARB waveforms that contain repeatable transport stream (TS) short video playback are a cost-effective solution for integrated module design and final subjective evaluation
