Encoded programs may be disabled or sent to one or both output ports - ASI or QAM, user selectable. The output timing is restamped and null packets are managed as required.

Built in multiplexer circuitry combines the outputs of all enabled encoders in an EH24A into multiprogram transport streams, one to the QAM output and one to the ASI output.

MPEG program numbers in the output transport stream by default will be assigned sequentially, corresponding to the encoder number. The leftmost encoder input, as viewed from the rear panel, will be # 1. If the Ethernet remote access is used, the MPEG and virtual channel (major and minor) numbers may be user selected to any desired MPEG-legal numbers and program names, up to 7 characters in length, may be added.

Any or all of the enabled encoders may be directed to the ASI output by means of the user selectable program filter. If EAS operation is used, this output can be assigned to loop the EAS alert program to additional EH24As. It can also loop DTA data.

Any or all of the enabled encoder outputs may be directed to the QAM Modulator by means of the user selectable program filter.

General Description

EH24A

The Drake model EH24A, encoder host, is the core multiplexer, QAM modulator, up-converter, ASI output, user interface, and power supply for the SDE24/SDE24A, HDE24, and SDI24A encoder modules. Up to six encoder modules can be

installed into the EH24A via rear panel access. SDE24/SDE24A encoders can encode one or two programs, depending on whether MPEG2 or MPEG4/H.264 encoding is used (see below), per module. Typical applications are to provide MPEG video in MDUs, medical facilities, libraries, stadium video networks, private cable and other QAM applications. The EH24A may be used in Edge or headend applications. There are two multiplexers in the EH24A, one providing an ASI output stream

provides EAS implementation and allows low speed data streams to be added to the output for purposes such as DTA channel mapping and code upload.

SDE24/SDE24A

Each SDE24 module contains two encoders and if MPEG2 encoding is desired for two programs, two MPEG2 transport streams can be generated. If MPEG4, H.264 encoding is desired, each SDE24 module can encode one program to an H.264 output stream. Another option is to encode one program in MPEG2 and the second program in H.264. The SDE24/SDE24A accepts either NTSC or PAL video inputs. The SDE24A is capable of MPEG4, H.264 encoding in both inputs if desired.

***IMPORTANT NOTICE***

When installing the SDE24A in a EH24A chassis (stock # 1002510A), the EH24A must have firmware version 3.0 or higher. Should you require any technical assistance, please contact DRAKE Service at (937) 746-6990.

SDE24EAS

and one providing a stream to the built in QAM modulator/upconverter. The latest firmware release

This is a specialized version of the SDE24/SDE24A to be used, when EAS is needed, to encode the EAS

program. EAS mode is provided by one of 2 methods, or both.

1) By installing the SDE24EAS module in slot 6 of the EH24A. This module has only a single composite input instead of the two inputs of the standard SDE24/SDE24A. It’s video and audio input will be provided by an external EAS contoller providing a NTSC composite alert message. When EAS is activated, the transport stream, created by the SDE24EAS,

replaces the transport streams that were coming from the other encoder modules in the EH24A. All programs will then become the EAS alert program. Only one SDE24EAS is required per headend. The alert can be encoded in either MPEG2 or MPEG4/H.264. All programs will be the same.

2) SCTE18 mode. In this mode, when an EAS alert is activated, the EH24A will place the SCTE18 table into the transport

stream. The SDE24EAS will encode the alert program. SCTE18 capable receivers are told where to tune.

Features

EH24A Features

The EH24A encoder host platform is a 19’’ rack mountable chassis that is 2 RU tall and can accept up to six modules that are

inserted into slots via the rear panel.

SD Encoding: The SDE24/SDE24A is the SD dual encoder module. Up to six of these modules could be installed in

the EH24A. Programs can be encoded in MPEG2 or MPEG4/H.264 (AVC). Audio is encoded using a choice of Dolby Digital

encoding or MPEG1, layer 2 (MP2)encoding.

***IMPORTANT NOTICE***

When installing the SDE24A in an EH24A host chassis (stock # 1002510A), the EH24A must have firmware version 3.0 or

higher. Should you require any technical assistance, please contact DRAKE Service at (937) 746-6990.

EAS Message Encoding: If EAS is to be utilized, then up to 10 SD MPEG2 programs or 5 SD H.264 programs, or a mix,

may be encoded in each EH24A/EH24A in addition to an EAS message program that is encoded in slot 6 of just one ‘master’ EH24A. One SDE24EAS is required per headend to be installed in the ‘master’ EH24A. Additional ‘slave’ EH24As can be included via simple ASI looping through each EH24A using an ASII card in slot 6 of all slave EH24As. The EH24A supports

the emergency alert system in two ways. SCTE18 table support is provided and also substitution of normal program

video with EAS program video, on all EH24A encoded program PIDs, is provided. Either method or both may be operator

selected.

Program Filtering and Multiplexing: The EH24A contains transport stream multiplexers that can multiplex any or all

of the program streams from the encoders. The user may select what programs from the encoders to include in the QAM output channel and also the user can select, independent of the QAM output, what programs to output via the DVB-ASI port. The QAM RF output can be specified for either off-air or CATV frequency plans in the 54 to 1002 MHz spectrum. The EH24A and installed encoder modules are powered by a built in power supply.

DTA Data

DTAs (Digital Transport Adapters). A Drake created PC program can be used to generate the data that would be then input

to the EH24A. This data generates a transport stream to provide a channel map (SCTE65 tables) for the DTAs. Also, firmware

update data can be sent to the DTAs if needed.

ASII: The Drake model ASII input module is supported to provide an ASI input for slave EAS operation and for DTA

data input as described in previous paragraphs.

Support:

One input slot in an EH24A can be used to input low speed data via ASI that may be used by system
