OVERVIEW
Models 8084/8084AD/8085 Closed Caption Encoder Manual
1.2.2

Serial Digital Video Path Features:

•
Keys directly into 4:2:2 (525 or 625 line) digital video bitstream.
•
8 or 10 bit SDI video resolution supported.
•
Serial digital video input provides automatic cable equalization on cable
lengths up to 200 meters of low loss coax such as Belden 8281.
•
Two separate serial digital video outputs.
•
Serial Digital Video bypass relay activates automatically on power
failure to maintain the integrity of the program video path.
•
Analog composite monitor output with caption decoder provides a
means of verifying the caption information that is being encoded.
1.2.3

Component Analog Video Path Features (8084AD only):

•
Keys directly into 1Vp-p component analog (525 or 625 line) video
signal.
•
User may select either analog or SDI video path as upstream caption
source for data bridging applications.
•
Captions may be encoded onto both video feeds simultaneously when
the feeds are frame-locked.
•
Studio-quality video output with bypass relay protection.
•
Monitor output with caption decoder that provides a means of verifying
the caption information that is being encoded.
•
Video bypass relay activates automatically on power failure to maintain
the integrity of the program video path.
1.2.4

Data Encoding Features:

•
Data can be encoded into all caption and text channels in both video
fields.
•
Supports encoding of Extended Data Service (XDS) data packets
including V-Chip-compatible program ratings into Field 2
•
Supports encoding of WebTV-compatible URLs into Text Channel 2.
•
EDH packet checksum correction.
•
Keyer bypass mode allows video to pass through without keying any
signal in
•
Inserts Captions or Text articles into previously captioned material
using the versatile Stream Mode.
•
Data encoding line is selectable – 11 to 25 in NTSC, 6 to 25 in PAL.
1.2.5

Communications Features:

•
Serial communications protocol emulates EEG 270, EEG 370 and EEG
470 Encoders.
•
Supports Real-time and off-line captioning methods.
•
Monitor mode extracts caption data from video and sends it out the
serial port.
•
Maximum compatibility with a wide variety of caption software
packages.
