Link Electronics 812-OPJ NTSC/PAL Closed Caption Decoder, Source ID and XDS Ratings Monitor

Discover the advanced capabilities of the 812-OPJ NTSC/PAL Closed Caption Decoder, Source ID, and XDS Ratings Monitor. This sophisticated, high-tech device is designed to perform three essential functions: decoding closed captions, identifying the source of signals, and monitoring XDS ratings.

The 812-OPJ is an innovative solution for NTSC systems, capable of processing and displaying all standard line 21 closed caption format transmissions. This 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 in field 2.

The device supports nine standard data channels, including Captions 1 through 4 (CC1-CC4), Text modes 1 through 4 (T1 through T4), and Extended Data Services (XDS). These various operating modes can be easily selected from the menu displayed on the monitor screen.

The 812-OPJ is equipped with a complementary differential input amplifier, ensuring high common mode rejection. Its phase-linear keyer seamlessly inserts decoded characters into the video image, with differential gain and phase within 0.1% and 0.1deg respectively.

The Source ID function of the 812-OPJ can add up to 13 lines of alphanumeric characters (at 16 characters/line) to its video input signal. This can be done using an RS-232 interface or a simple two-button front panel menu.

As a Closed Caption Decoder, the 812-OPJ can monitor any of the standard Line 21 data channels (CC1, CC2, XDS) and produce a decoded character output. As a Program Ratings Monitor, it can extract the Line 21 XDS data carrying the "content advisory" (V-Chip) information and display an appropriate ratings "icon".

The device supports both NTSC and PAL video standards, and its three input/output BNCs can be configured as a looping input pair with one output or as a single terminating input with two outputs. The Source ID function also features EEPROM storage for up to 16 messages with a remarkable 10-year data retention.

Experience the state-of-the-art technology of the 812-OPJ NTSC/PAL Closed Caption Decoder, Source ID, and XDS Ratings Monitor, designed to enhance your viewing and monitoring experience.
