ATSC/QAM Transcoder

The AQT8-QAM transcoder allows the user to create a line up from off-air and/or cable feeds for coax or IP distribution. The unit simultaneously transcodes eight (8) QAM/8VSB input channels to pass thru (8) QAM and (8) IP transport streams.

For clear QAM and 8VSB inputs, the unique MPEG tables (PAT, PMT, PSIP, VCT, MGT, RRT, EIT and ETT) associated with all programs contained in the RF inputs (major and minor channels) are transferred to both the QAM and IP outputs. This means the virtual output channel numbers, names, program information, etc. on the QAM and IP outputs are the same as their RF input sources. User settings designed for MSO applications permit encrypted QAM input(s) to pass all stream packets to the AQT8-QAM outputs for total conditional access transparency.
The AQT8-QAM features Emergency Alert System (EAS) program switching through either an ASI or IP format EAS input and terminal block contacts for triggering. When EAS is invoked, all QAM and IP output programs from 8VSB or clear QAM inputs are interrupted to display the EAS message. Outputs derived from encrypted QAM input channels do not support EAS from the AQT8.
