The PTC-892 Caption Encoder/Decoder SD-SDI/Analog from Link Electronics offers captioning encoder, decoder, and data recovery functionality and is capable of inserting, decoding, and recovering data of captions and text for NTSC/PAL for the following signals: composite, Y/C, S-video, RGB, YUV, and SDI.

Captioning and text may be inserted (encoded) in either field of the Vertical Blanking Interval (VBI). That inserted data may be displayed as open captions through the decoder output(s). Caption data on the incoming or outgoing video may be recovered from either field of the VBI. This data can be sent to another encoder or a language translation machine or program, then re-encoded or captured by a program for manipulation. Encoding, decoding, and data recovery may be done simultaneously and controlled by the front panel menus or by serial communications.

Inputs and outputs are provided for both SD-SDI and SD analog, including composite, Y/C, S-video, YUV, and RGB. The power loss feature bypasses the composite analog and SDI when AC power to the unit fails. In response to the FCC mandated requirements, captions shall not interfere with emergency crawls. The unit incorporates a weather-lift feature that moves the caption up to 4 lines whenever a contact-closure is detected on its GPI input. The number of lines can be controlled by the front panel or by software commands.

The serial communication port(s) allow for remote captioning. The dual ports allow multiple encoders to be controlled simultaneously, with a back-up communication port, or with data recovery out of its ports. Port 1 is either a "B" type USB port or RS-232 port. Port 2 is either a RS-232 port or an optional modem. Both ports can be set to have different baud rates independently through the front panel menus.

Front panel LEDs show unit status. Front-panel push buttons allow for control of the unit. This unit is compliant with V-chip technology and TSID ready. This technology is incorporated in the firmware of the device. It handles automatic repetition of the V-chip data and can interweave it with existing line 21 closed captioning data. It has a Longitudinal Time Code (LTC) input for precise caption timing with the video. A Front-panel Vacuum Fluorescent Display (VFD) shows various functions and menus.
