Wohler Releases New CD-1 Caption/Subtitle Adaptor

Wohler Technologies has unveiled its new CD-1 caption and subtitle video monitor adaptor. The innovative CD-1 decodes and renders captions or subtitles for any digital video monitor to display, as well as de-embedding audio, conveniently allowing the operator to confirm the presence and accuracy of critical video, audio, and caption data using existing or low-cost monitors that lack caption display capability.

“As a compact and exceptionally simple solution for handling caption inputs and outputs, the CD-1 brings unique versatility to monitoring of the SDI stream across a broadcast plant or production facility,” says Kim Templeman-Holmes, VP of global sales and marketing at Wohler. “The CD-1 is a clever box that not only allows users to pull apart a 3G, HD-SDI, or SD-SDI signal quickly and easily, but also lets the user pick any stereo audio pair from the SDI stream for listening and cross-reference. It also acts as a splitter, providing flexible output of the SDI signal depending on the requirements of the application and preferences of the user.”

The CD-1 automatically detects and decodes WST, OP-47, and EIA-608/EIA-708 subtitles, covering captioning standards around the world. Suitable for any point in the broadcast or production chain, this small externally powered unit translates a 3G/HD/SD-SDI multirate input containing captioning signaling into a burned-in 3G/HD/SD-SDI or DVI signal with open captions added to the picture.

Output options include two open-caption 3G/HD/SD-SDI outputs, a DVI open-caption output, and an RS-232 output of caption contents. The new Wohler device can also de-embed any one of the eight pairs of audio from the SDI signal and output it as a stereo analog output for use with headphones or connection to an external audio monitor.
