Microvideo Closed Caption Encoder

Closed Caption Encoding is used to provide subtitles for the hard of hearing on home videos and for television in the USA.
The Microvideo Closed Caption Encoder provides a means of inserting the data for the captions directly into a serial (270Mb/s) D1 digital video signal. Caption text and control data are sent to the Encoder via an RS232 or RS422 link from a computer. The closed caption waveform is then generated internally and inserted into the serial stream on the correct lines. Up to 5 lines per field (e.g. 18 to 22) may be inserted simultaneoulsy. This unique feature allows the Microvideo encoder to offer the ability to transmit subtitles in up to 5 different languages.
