Wohler update provides dual-channel HD/SD-SDI closed-captioning encoder with EIA-608/EIA-708 support

April 17, 2009

Wohler has updated the HDCC-200A HD/SD-SDI dual-channel, closed-captioning encoder/decoder bridge to support the U.S. subtitling standard (EIA-608/EIA-708) as well as the OP47 standard being adopted worldwide. Occupying just one card slot, this compact modular solution simplifies closed-captioning encoding of two independent SD and/or HD sources to bring greater convenience and flexibility to digital and multiformat broadcast and production workflows.

The HDCC-200A module encodes closed-captioning data into SD Line 21 (EIA-608/NTSC) or directly into the DTVCC transport stream (EIA-708/ATSC), encoding two independent sources with unique closed-captioning data. When the signal output is intended for use in different distribution, it encodes two independent sources with identical data. Each of the card's channels has a "clean" output and a captioned output with a burnt-in, closed-captioning display that enables easy monitoring. The card automatically formats captioning data for insertion into the HD VANC space and simultaneously converts WSS and GPI data for subsequent insertion into HD VANC. This allows that data to be recorded on an HD storage device or distributed via the facility's digital video distribution network. In decoding mode, the HDCC-200A converts HD VANC data back for the SD-SDI output stream.

The card is available in two sizes to fit either the 3RU Eurocard frame or the 2RU Ross Video openGear frame. Additionally, a separate interface will allow the HDCC200A to be used in existing Evertz frames without further modification to the frame.
