.      The HDMI2QAM is a dual-channel, high definition MPEG 2 broadcast distribution encoder with built in QAM modulation and RF up-conversion. Its primary application is for use with clear QAM distribution to ATSC televisions. The HDMI2QAM automatically detects video and audio, encodes, multiplexes and generates program information (PSIP); it then modulates and up-converts two channels for distribution via coax. Closed captioning and support for Emergency Alert (EAS) are standard. Applications include private cable, hospitality, medical, education and cable television. .

Features
.

High and standard definition dual encoding:
The HDMI2QAM automatically detects two channels of video and audio via HDMI 1.3, encodes and multiplexes the signal into a multiple program transport stream with either DVB or ATSC table compliance.

Automatic video detection:
Video rates are automatically adjusted based on HDMI video input resolution, audio passthrough or encode and QAM modulation target.

QAM modulation and RF up-conversion:
For cable television applications, the unit modulates the signal using QAM Annex A and B and up-converts two video and audio services multiplexed on one carrier frequency for distribution via coax networks.

ASI and GigE output:
For non-RF applications, the HDMI2QAM delivers ASI (75 Ohm source per EN500083-9) and GigE (MPEG2 or optional RTP multicast transport egress).

Program information:
The HDMI2QAM is compliant with the ATSC A69 Program and System Information Protocol (PSIP).

Closed captioning and EAS:
Support for closed captioning and Emergency Alert (EAS) is standard.

DVB SI:
The HDMI2QAM is compliant with ETSI EN 300 468 Service Information specification.

Flexible configuration & control:
Controlling and configuring the HDMI2QAM is easy using the integrated front panel keypad and LCD and web page for configuration and monitoring.
