EH244 ENCODER HOST SERIES
INTRODUCTION
General Description
The Drake Digital EH244 Encoder Host is a platform for supporting Drake Digital modular MPEG2
and H.264 video encoders, including the SDE24A, HDE24, and SDI24A. The EH244 Encoder Host
multiplexes the outputs of the Encoder Modules into a digital output (QAM RF, ASI stream, or Internet
Protocol data stream - IP, depending on which EH244 model you have purchased) stream, configurable
via a front panel interface or Ethernet web server. The EH244 Encoder Host also includes provisions
for Emergency Alert System (EAS), using either video replacement or SCTE18 control messages.
The EH244 Encoder Host accepts up to 6 Drake Digital Encoder Modules, and allows each encoder’s
output program to be included or excluded from the outgoing digital QAM RF Channels, IP program
data stream, or the ASI output stream (or a combination of these output formats). The EH244 Encoder
Host Series comes available in two base models that can be ordered with various output format
configurations tailored to your specific application requirements.
Models / Output Configurations
The EH244 Encoder Host Series is available in two standard models:
5
EH244-Q Quad QAM Encoder Host
This base unit outputs four (4) sequential Clear QAM RF channels.
EH244-IP (IP Output) Encoder Host (Part Number 1002578)
This base unit outputs a single (1) Internet Protocol (IP) data stream.
From these two base models, you may order alternate or additional output format configurations.
From the base EH244 Quad QAM Encoder Host, you may select the following additional output format
configuration:
EH244-Q-ASI Quad QAM / Quad ASI Encoder Host (Part Number 1002569)
This unit outputs four (4) ASI streams as well as four (4) Clear QAM RF channels.
The second base model in the EH244 Encoder Host Series, is the EH244-IP. The EH244-IP utilizes
a video codec to output MPEG transport streams encapsulated in a stream of IP (Internet Protocol)
packets. From the base model EH244-IP (IP Output) Encoder Host, you may select the following
additional output format configurations:
EH244-IP-ASI Quad ASI / IP Encoder Host (Part Number 1002579)
This unit outputs four (4) ASI streams in addition to a single (1) IP data stream.
EH244-Q-IP Quad QAM / IP Encoder Host (Part Number 1002580)
This unit outputs four (4) Clear QAM RF channels in addition to the single (1) IP data stream.
EH244-Q-IP-ASI Quad QAM / IP / ASI Encoder Host
This unit outputs four (4) Clear QAM RF channels in addition to the single (1) IP data stream
and four (4) ASI streams.
(Part Number 1002568)
(Part Number 1002593)
*NOTE: All models / Output Configuration Types of the EH244 Encoder Host Series will have a
separate isolated ASI Output Port. This separate ASI Output is a low-data ASI port used
only to output SCTE-18 data for EAS or DT A MODES when daisy-chaining several EH244
Series or EH24 Series models together in a headend (see Chapter 2, INST ALLATION AND
MOUNTING on Page 6 for specific information).

INSTALLATION AND MOUNTING
The EH244 Series Encoder Host is designed to be installed in a standard 19’’ rack.
*NOTE: All Drake Digital Encoder and Interface Modules must be installed in the EH244 Series
chassis before power is applied. DO NOT INSERT ENCODER MODULES OR INTERFACE
MODULES WHILE THE EH244 SERIES UNIT IS POWERED. Inserting any Encoder or
Interface Modules into the EH244 Series Encoder Host chassis, while it is powered, will
void the EH244 Series Encoder Host’s and Encoder / Interface Modules’ warranties.
Image: Rear view of base model EH244 Quad QAM Encoder Host
EH244 ENCODER HOST SERIES
Module Slot Number: 1 2 3 4 5 6
Encoded Program Number: 1 (& 2*) 3 (& 4*) 5 (& 6*) 7 (& 8*) 9 (& 10*) 11 (& 12*)
The input modules that will be inserted into the back of the EH244 Series chassis, are referred
to in this manual (and in the Ethernet Control Interface, Chapter 3 CONFIGURATION on Page )
numerically by position of the Slot that they occupy. They are 1, 2, 3, 4, 5, and 6, from left to right,
when viewing the rear of the EH244 Series unit. Each Encoder Module’s program number will be
assigned based on its Slot location:
Slot 1 will provide programs 1 (*and 2 if using an SDE24 Dual Standard Definition MPEG Encoder
Module); Slot 2 will provide programs 3 (*and 4); Slot 3 will provide programs 5 (*and 6); etc.
*NOTE: In the case where a Slot has a single program Encoder Module inserted in it, for
ident-ification purposes, the Slot will provide only the odd-numbered program.
Ex: If there are six (6) HDE24 High Definition MPEG Encoder Modules (which are single
program Encoders) inserted into the six (6) Slots of the EH244 Series Encoder
Host, the programs’ numbers being output from the HDE24’s to the EH244 Series’
multiplexer would be identified as programs 1, 3, 5, 7, 9, and 11.
EAS - Modes (Emergency Alert Services)
If the EH244 Series Encoder Host will be used in an EAS-enabled system, and the unit will be used
as the ‘master’ EAS unit in Slot 6 Mode (or Slot 6 + SCTE 18 Mode), a Drake model SDE24EAS
(EAS Input Encoder) module must be installed in slot 6 of the chassis.
If the EH244 Series Encoder Host is configured as a ‘slave’ EAS unit (Slot 6 Mode or Slot 6 + SCTE
18 Mode), a Drake model ASII module (ASI Input) must be installed in slot 6, and wired to the ASI
Output port of the previous Encoder Host (EH24, EH24A, or EH244 Series) in the chain.
