Cisco Hybrid Decoder
When a playback feature is requested, the hybrid decoder retrieves the video stream from the
proper ISP and displays it on the proper matrix switch port. This process is transparent to
operators.
The hybrid decoder is connected via Ethernet to the IP network and via a coaxial cable to the
matrix switch. A port from the matrix switch is reserved to be the input port from the hybrid decoder.
When an operator requests a playback feature from the keyboard, the ISP instructs the matrix
switch to redirect the reserved input port to the monitor output port that is associated with the
requesting keyboard.
Configuring the Bosch LTC 8200 Matrix Switch
The Cisco hybrid solution supports integration with the Bosch matrix switches that are listed in
Table 6 on Page 4-1.
The examples in this section are based on the LTC 8200 matrix switch and IntuiKey keyboard, but
most of the concepts apply to other Bosch models.
By default, the 16 input ports of the LTC 8200 are configured as Camera 1 through Camera 16.
These port numbers must match the camera number or peripheral ID of a Cisco IP gateway
encoder. In an environment with more than 16 cameras or with camera numbers that are greater
than 16, the camera numbers on the matrix switch must be changed to match the camera number
of the corresponding encoders.
Allegiant Master Control Software
Bosch provides configuration software for the LTC 8200 that allows changing camera numbers and
making other configuration changes. The Allegiant Master Control Software may be obtained from
Bosch.
Note:
This software requires a license from Bosch. A parallel port hardware key also may be
required.
To change camera numbers, launch the Master Control Software from a Windows workstation.
