Link Electronics PDR-870 Closed Caption Decoder & Data Recovery Decoder RS-232
The PDR-870 is a high performance Closed Caption Decoder for the NTSC and PAL systems. It is capable of processing and displaying all standard closed caption format transmissions--including the EIA-608 Extended Character Set--in the manner of a typical closed caption decoder. A stable input video source is required. Nine standard data channels are supported by the PDR-870: Captions channels 1 thru 4 (CC1-CC4), Text channels 1 thru 4 (T1-T4) and Extended Data Services (XDS). The various decoding channels are selectable by four front-panel toggle switches. Additional front-panel toggle switches provide NTSC/PAL video standard selection, drop-shadow or box character keying, and internal/external video. The internal video function allows the PDR-870 to generate its own video as a medium for producing open captions. In addition, the PDR-870 can accept an RS-232 data stream and directly produce open captions, serving as a character generator decoder. Along with it's powerful decoder functions, the PDR-870 can serve as an accurate V-Chip ratings monitor. All rating information described by EIA-744 may be displayed on-screen by the PDR-870. Both TV Parental Guidelines and Motion Picture Association of America (MPAA) ratings are supported. The PDR-870 can recover incoming Line 21 data and send it to a computer terminal via the RS-232 port. This data may be recovered with or without the embedded closed caption control codes.
