Blonder-Tongue AQT8-QAM/IP 8x8 ATSC/QAM Transcoder

Blonder Tongue's AQT8-QAM/IP is especially designed to allow operators to create a custom channel line up from off-air and/or cable feeds for coax or IP distribution. Through this high density, low-cost, flexible 1RU chassis, the AQT8-QAM/IP provides a transcoding solution for multi-channel processing - in turn reducing the equipment, space and power needed. Additionally, the unit gives the user the ability to change the PID, Program #, Short Name, Major and Minor Channel (PSIP) information.

The unit accepts up to eight (8) 8VSB or QAM channel inputs, supporting up to 20 programs on each input, and 20 programs total on the eight (8) IP outputs. The AQT8-QAM/IP features Emergency Alert System (EAS) program switching through either an ASI or IP format EAS input, and terminal block contacts for triggering EAS messages.

The AQT8-QAM/IP features Emergency Alert System (EAS) program switching through either an ASI or IP format EAS input and terminal block contacts for triggering. EAS messaging is available on the IP and QAM outputs when the QAM Output Mode is set to "Default IP" or "IP#". There will be no EAS messaging on the QAM output channels when in the "RF Default" mode.

Blonder Tongue AQT8-QAM/IP Features:

• Accepts up to 8 RF inputs in 8VSB/QAM format
• Supports up to 20 programs on each input and 20 programs (total) on the 8 IP outputs
