Remote User Interface

The Remote View application can be used to remotely view
Alarm Configuration:
test results and control the monitoring system. Unlike a
typical browser-based client view, the Remote View comes
with a fully featured Windows® application, and
dynamically displays video thumbnails and all test results.
In addition, it streams audio and video data from the system
to the client PC over an IP network connection, allowing
continuous decoding of a video program for visual
verification of Quality of Service (QoS).

Error Logging and Alarms

All errors detected are logged in a database pre-installed in
the system. The logging feature allows the operator to search
specific errors based on various searching criteria, including
error code and time period the error has occurred. Selected
errors can be exported to a text file. The Q Check ASI allows
users to create transport stream profiles, and the system will
test the actual input data against user entered profile, record Computer Modules, Inc.
and alarm any deviations from user defined profile. The 11409 West Bernardo Court
alarm triggers can be configured based on the overall TS San Diego, CA 92127
