Television New Zealand (TVNZ) has invested in captioning systems from Screen Subtitling for its SD and HD services.
As part of the deal, Screen has supplied a Polistream system comprising two P5000s, three P4000s and two A4002s, which will be used to transcode Teletext captions into DVB subtitles for the TVOne and TV2 HD services on DTT. Screen also made specific design alterations to the system to meet TVNZ's specific requirements to output data directly over UDP rather than the traditional ASI stream.
