Wohler has introduced a realtime, single-card-based standards converter that enables on-the-fly conversion of WST/OP-47 to CEA-608/CEA-708 captioning standards, an industry first.
The newest addition to Wohler's HDCC captioning card product line, the WST-708 card boasts two 3G/HD/SD video channels and allows for direct bridging and transcoding of captions/encoded subtitles without the need for additional hardware or offline conversion processing. In addition, the WST-708 card provides transcoded data out of serial and/or Ethernet ports for logging, closed-caption file regeneration, direct connection to an ATSC encoder, and use with the SMPTE Grand Alliance protocol. The WST-708 card comes in an openGear form factor and is available as a single- or dual-card, redundant power supply, 1RU standalone unit.
"Converting captions while converting video framerate proves to be a difficult challenge, forcing many broadcasters to entirely re-caption converted video — which brings delays and additional costs," said Renaud Desportes, director of Wohler's ancillary data product line. "The increasing amount of captioning regulations, coupled with the need to distribute content quickly across multiple platforms and destinations, necessitates this type of solution. We are proud to once again be leading the way in providing broadcasters around the world with innovative solutions to meet their specific captioning requirements."
