LINK ELECTRONICS PDA-895
The PDA-895 is both a Closed Caption Encoder and Decoder capable of inserting and decoding caption and text data on NTSC, PAL, Analog Y/C, RGB, YUV, and SDI.
Caption and Text data may be inserted in either field of the Vertical Blanking Interval. In addition, data on the incoming video signal may be recovered from either field of the VBI. This incoming data may be displayed as Open Captions, using the built-in Closed Caption Decoder, and captured by a computer utilizing the PDA-895's serial data port. Each of these important functions, Encoding, Decoding, and Data Recovery may be done simultaneously.
The Closed Caption Decoder's functions may be controlled from the front panel while the Encoder and Data Recovery functions are controlled via the serial data port, on the SDI and analog composite and the open caption outputs.
Inputs and outputs are provided for, not only NTSC and PAL, but also Analog Y/C, RGB, YUV, and SDI. The power-loss feature bypasses the analog and SDI when AC power to the PDA-895 fails.
In response to the FCC mandated requirements, captions shall not interfere with emergency crawls.
The PDA-895 incorporates a weather-lift feature that moves the captioning up 1 to 3 lines whenever a contact-closure is detected on it's GPI input.
For remote captioning applications, a second serial port is available as a modem input. Both serial ports may be configured for RS-232 or RS-422 I/O. Front panel DIP switches are provided to select the baud rate selections of 1200, 2400, 4800, and 9600 bps.
Modem speeds are 1200 or 2400 baud. The modem takes priority over the serial port, and when the modem hangs up, the PDA-895 is restored to the last mode left by the modem.
Front panel LED's show the unit status and the presence of serial data. A pair of front panel push-buttons allow the user to run an encoded test message or to place the unit in by-pass mode.
The PDA-895 is ready for V-Chip technology. LINK Electronics is incorporating this technology in the firmware of the PDA-895. The PDA-895 handles the automatic repetition of the "V-Chip" data and can interleave it with existing Line 21 Closed Caption data.
