Link Electronics PCE-845 Closed Caption Encoder, NTSC and PAL, Field 1 & 2 On Line 21

Enhance your video production capabilities with the PCE-845 Closed Caption Encoder, a sophisticated and high-tech solution for embedding closed caption and text data into your video signals. This state-of-the-art encoder is expertly designed to insert four distinct channels of data into the vertical interval of line 21, field one of the NTSC signal. These channels include Caption Channel One, Caption Channel Two, Text Channel One, and Text Channel Two, ensuring a comprehensive captioning experience.

The innovative PCE-845 goes beyond the basics by also processing data on Line 21 of field two, adhering to the latest FCC specifications for closed captioning. With future-proofing in mind, the PCE-845 is equipped to handle data insertion on lines 10 through 25, with a simple internal jumper to select the correct line placement.

Compatibility is key, and the PCE-845 excels with its ability to work seamlessly with both NTSC and PAL systems. For PAL closed captioning, data is typically inserted on Line 22 of field one. The unit's versatility is further enhanced by its dual voltage operation, accommodating 115/240VAC at 50/60Hz, with internal selection for global use.

The PCE-845 offers a range of input signal options, including composite video, S/VHS, or component video (Y, R-Y, B-Y), and boasts two composite video outputs. When using a component format, the encoder meticulously matches the delay of each signal path to ensure a transparent throughput that maintains the integrity of your video.

Advanced connectivity is provided through an RS-232C Input/output data port on the rear panel, supporting baud rates from 600 to 4800 (jumper selected). A secondary data port is available for connecting an external modem. The encoder's front panel features a "TEST" switch that generates a test message on line 21, verifying the encoder's proper functionality.

For added convenience, the PCE-845 allows for both local and remote caption data reception through simultaneous connections to a modem and computer. Operational status is easily monitored with two front panel LEDs that indicate activity in field one or field two, along with additional indicators for input video and RS-232 presence.

The encoder also offers a user-friendly by-pass mode, which can be activated from the front panel, through software commands, or via remote control. This mode is designed to be transparent, ensuring that the video signal remains glitch-free when selected.

With the PCE-845 Closed Caption Encoder, professionals in the broadcast, post-production, and video editing industries can achieve advanced and accurate closed captioning, making their content accessible and compliant with regulatory standards.
