HDMI2QAM Dual Channel High Definition Encoder

• 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. Optionally, the HDMI2QAM will support Adtec's DTVGuide web hosted SI server for complete and dynamic PSIP or SI guide information.
• 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.

PRODUCT DESCRIPTION

The HDMI2QAM is a dual-channel, high and standard definition MPEG 2 broadcast distribution encoder with QAM modulation and RF up-conversion built in. 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.
