The PDC-888 CC Decoder, CV, CAV & Y/C from Link Electronics is a closed-caption decoder for use with both NTSC and PAL systems. It is capable of displaying captions for CV, CAV, and Y/C as required by EIA-608. It includes the codes specified by the FCC Report and Order on General Docket No. 91-1 and EIA-608 recommended practices for captions, text, and XDS.
Nine standard data channels are supported by the PDC-888: caption channels 1 through 4 (CC1-CC4), text modes 1 through 4 (T1 through T4), and extended data services (XDS). The various operational modes are selectable from four front panel switches.
The component inputs accept RGB or YUV. All connectors use BNC except the S-video connector. The caption data is keyed into all component channels. The unit automatically detects PAL or NTSC. The AC line voltage selects from 96 to 245V.
All video inputs including CV, CAV, and Y/C have AC power by-pass in the event of power line failure. Component video is internally terminated. S-video offers standard levels using a 4-pin mini-din connector for ease of operation. A complementary differential input amplifier assures high common mode rejection while its phase-linear keyer cleanly inserts decoded characters into the video image. Differential gain and phase are within 0.1% and 0.1 degree respectively. The unit is contained in a standard 1U 800 Series chassis.
