The ENC-896 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
ENC-896'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 by-passes the analog
and SDI when AC power to the ENC-896 fails.
In response to the FCC mandated requirements,
captions shall not interfere with emergency crawls.
The ENC-896 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 ENC-896 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 ENC-896 is ready for V-Chip technology. LINK
Electronics is incorporating this technology in the
firmware of the ENC-896. The ENC-896 handles
the automatic repetition of the "V-Chip" data and
can interleave it with existing Line 21 Closed
Caption data.
