Signal Processing Systems : Decoders & Encoders : Evertz - 8084

SD-SDI Caption Encoder

Model: 8084

Keys directly into a 525 line or 625 line component (4:2:2) digital video bitstream
Can add captions, text, web links or Extended Data Service information to previously captioned programs
Individual caption and text data streams can be passed, modified or removed from the incoming video
Support for text insertion from articles stored in the encoders by the captioning software
Support for Extended Data Service (XDS) to encode program information including TSID, CGMS-A and V-chip content advisory ratings

The 8084 is a full broadcast quality Closed Caption Encoder which generates line 21 caption data directly into the digital bitstream. The 8084 allows data to be encoded into all caption and text channels in both field 1 and field 2 of the video. It can also encode Extended Data Service (XDS) packets into field 2 supporting such services as Transmission Signal Identifier (TSID), Copy Generation Management System (CGMS-A), station name, call letter identification, program name, classification, remaining air time and content advisory ratings (compatible with V-chip decoders). The 8084 is highly configurable to guarantee maximum compatibility with a wide variety of applications and software packages. The encoder can be configured to individually manipulate each data stream independent of the others. The 8084 is also compatible with various automation and traffic programs such as Enterprise's "BMS Traffic System".

V-chip blocking codes selectable from front panel menus
Selectable V-chip default rating after timeout
Bypass relay can be activated by GPI, front panel or automatically on power failure to allow the input video to pass through the unit unprocessed
Three RS-232/RS-422 serial ports allow simultaneous control from three computers, for applications such as in house captioning, XDS insertion and more...
Built in modem interface for dial-up real time captioning. Support for an optional second internal modem
Built-in composite analog monitoring decoders provide real-time verification of encoded data. The decoded captions, text or XDS data is inserted as open captions on the monitoring video outputs
Composite decoders can display these XDS packet types: Network Name, Call Letters, Program Name, Program Length, Time in Show, Program Type, Program Description and Program Rating
Built in test message inserts data into all 9 data channels
Ability to offset the effect of downstream component to composite encoders which add setup to line 21
Monitor mode allows caption data to be read directly from line 21 and output on the serial port
VBI bridge function allows captions to be copied from one video source to another using two 8084 or 8084AD units
GPI input to provide caption shift. This input can control the shift of rows 12 to 15 up to rows 1 to 4 when activated. Intended to provide compliance with FCC order prohibiting obstruction of weather warning text which often appears on the bottom of the s
Can encode captions on lines other than line 21 for specialized applications
EDH Packet checksum correction ensures SDI video integrity to downstream equipment
SMPTE ST 269 fault reporting output
Optional LTC input for setting internal clock
Supports a wide variety of caption software including the following: The Captioning Center - CCSQ and CCMS, Captions Inc. - Smart Encoder V 1.0b, Evertz ProCAP, Cheetah Systems
