Before You Begin
The TSI-1000 extracts the Transport Stream Identifier (TSID) from an ATSC ASI transport stream and closes GPIO
contacts when the value does not match a user supplied value. This makes it an ideal device for signaling a
modulator that a transport stream is present and is for the correct television channel.
The TSI-100 monitors the ASI transport stream and provides a GPIO output when the TSID is not correct. This
signal may be used to control other devices or to signal the fault.
The TSI-100 is ideally suited for use in remote television broadcast translators to mute or power off the
re-transmitter when the main broadcast goes off the air. It may also be used in a cable head-end for the same
purpose.
Features
The following features make the TSI-100 ideal solution for detecting a change in a transport stream source:
• Signals a remote device or alarm when an incorrect transport stream or no transport stream is present
• Simple setup, enter the TSID of the transport stream
• Two GPIOs provide both normally open and normally closed signaling
• SNMP capable for monitoring with third-party systems
• User configurable “must match” TSID
• Adjustable triggering on the detection of an incorrect TSID
• Adjustable triggering on the loss of the transport stream
• Frame-accurate triggering: each trigger is delivered within one video frame time
• Fits openGear frames

User Interfaces
The TSI-100 includes the following user interfaces.
DashBoard
DashBoard enables you to monitor and control openGear frames and cards from a computer. DashBoard
communicates with other cards in the frame through the Network Controller Card. The DashBoard software and
manual are available for download from our website.
