DI470DTS Digital Smart Encoder

with ATSC Closed Caption Server Interface

The Model DI470DTS SMART ENCODER is the ideal choice for implementing Standard and High Definition closed caption services. For Standard Definition video this encoder supports simultaneous insertion of two language captions into Line 21 of both fields. It also supports URL data for Interactive TV and XDS data for V-Chip. For High Definition encoding support it transcodes EIA-608 caption data into EIA-708 style caption services and bridges NTSC V-Chip and ITV Data for use by DTV to NTSC Down-Converters.

The DI470DTS is a digital version of EEG's industry standard analog Smart Encoder III. It utilizes the same command set and features. It has one SDI input and two SDI outputs, one of which is bypass protected. A dedicated serial data port supplies EIA-708 data to DTV encoders.

The DI470S has 3 serial Data Ports, one built in Modem and provision for a second internal Modem. The user may configure these Data ports according to operational needs. The serial ports can be configured for RS 232 or RS 422 operation.

The Digital Smart Encoder has many important features such as:

  • Two digital 4:2:2 SDI outputs encoded with EIA-608 compliant data.
  • Transmits EIA-708 data and EIA-608 compatibility data to the DTV encoder via RS232 or RS422 serial port.
  • Generates EIA-708 Output from Standard EIA-608 Input.
  • Supports Full-Featured Real-Time & Off-Line EIA-708 Captions.
  • Supports SMPTE 333M "pull" protocol and Grand Alliance "push" protocol.
  • Monitor mode provides capture of selected encoded data streams via serial port.
  • User setups allow insertion of default V-Chip and XDS data.
  • Supports the addition of captions, Interactive TV links and V-Chip data to previously encoded video.
  • Video output is by-pass protected for power failure via relay.
  • LCD Status display.
  • Non-volatile memory maintains user setups.
  • Precise Line 21 waveform digitally synthesized.
  • 3 Serial Data Ports provide dedicated I/O for multiple data services.
  • Internal modem provides support for dial-up real-time captioning.
  • Optional 2nd modem available for dual language captioning
