8084 & 8084AD

Analog & SD-SDI Closed Caption Encoder

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".

The 8084AD is a full broadcast quality Closed Caption Encoder which generates line 21 caption data directly into both analog and digital video feeds.

The built-in bypass relay, fault reporting output and optional redundant power supply ensure robust operation. The analog monitor output displays visible captions from any data channel, including many XDS packet types.

Closed caption file transfers are supported using Evertz ProCAP® solution. The ProCAP® Transfer Application (PT-SW-LITE + PT-HW-TC) supports offline closed caption file transfer directly to the encoder.

Features

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 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 screen Can encode captions on lines other than line 21 for specialized applications EDH Packet checksum correction ensures SDI video integrity to downstream equipment SMPTE 269M 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 - Captivator Offline Edit Version 2.1, Captivator Offline PostCAP 2.1, VITAC PostCAP 2.1, Computer Prompting and Captioning Co. - CPC-700 Version 6.20, National Captioning Institute - Text Encoding and Display System (TED) version 1.7, Autograph Systems - View level XDS controller, Rapid Caption
