HDE24A High Definition Encoder Module
The Drake HDE24A high-definition encoder module generates an MPEG2 or MPEG4 (H.264) video stream, with Dolby® AC3 or MPEG1 layer 2 audio. This module is designed to be installed into Drake's EH24 or MEQ1000-style chassis which provides the control and output interface to the unit. This configuration of encoder module and host chassis provides the ultimate in bandwidth management and economy by allowing multiple HD and SD streams to be multiplexed together dependent upon the limitations of the bandwidth of the chosen output: QAM and/or ASI (see EH24 and MEQ1000 manuals for more information on multiplexing). The HDE24A high-definition encoder accepts non-encrypted HDMI or component video inputs and can inject closed-captioning data from a synchronized composite video source (typically provided by the same decoder that produces the HD video stream). Composite analog audio inputs provide the audio source when component video inputs are used. Typically HDMI has embedded audio but if the HDMI is derived from a source converter that does not provide audio, such as DVI-to-HDMI, then the analog composite inputs may be used.

*for power requirements, see EH24 or MEQ1000 Specifications*
Remember that you can only insert two HD signals per QAM channel. So most of the time use (2) HDE24's and a MEQ1000.
But if you must have EAS capability use (2) HDE24 + (1) EH24 + (1) SDE24EAS (Emergency Alert Encoder) + (2) ASII (ASI input modules).
