Wohler Technologies says its new CD-1 caption and subtitle video monitor adapter decodes and renders captions or subtitles for any digital video monitor to display.
Furthermore the product de-embeds audio, 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.
The CD-1 automatically detects and decodes WST, OP-47, and EIA-608/EIA-708 subtitles and is designed to be suitable for any point in the broadcast or production chain. The 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 analogue output for use with headphones or connection to an external audio monitor.
