Section 5: Applications
The 491-series Smart Encoder platform is designed to support standard,
semi-custom, and custom EEG software solutions for a wide variety of
VBI and VANC data handling applications. These applications take
advantage of the HD491’s enhanced processing power, fast network
connectivity, simple browser-based configuration, and custom software
decoder platform to create powerful single-box solutions in any
encoding environment. Some of the most popular modules are pre-
installed on new units, though some pre-installed modules still require a
license key to activate. Others require a software update. For

iCap™ Secure Internet Captioning
The EEG iCap™ system is a real-time IP-based captioning system
designed exclusively for use with the 491-series Smart Encoder platform.
With iCap™, the 491 Encoder and a single LAN connection replaces both
an older encoder used with a dial-up modem line, and an external audio
coupler with an additional phone line, while improving system security,
quality of service, logging, and monitoring. iCap™ also greatly simplifies
encoding jobs with multiple captioners and/or multiple encoders by
creating dynamically networked, password-protected groups of Encoders
and enabled captioners with real-time status reporting to participants and
administrators.
The block diagram on the next page shows the basic cloud architecture
of the iCap™ system. Each Encoder logs in to a secure remote connection
server with its unique ID key and password automatically on startup.
Once the Encoder is authenticated into the system, remote captioners can
use the Encoder’s access code to connect through a dedicated high-speed
relay network. The captioners receive an encrypted audio stream and
caption monitoring from the HD491, and status messages from any other
encoders or captioners in the group. All connections to each Encoder, and
the start and stop times for any captioner sending data, are logged by the
servers and accessible through a secure administrative website. iCap™
provides high quality, low latency audio to captioners for improved
transcription accuracy, and automatic status and arbitration messages
eliminate common problems with loss of service due to dial-up modem
preemption or lock-out.
