Drake EH24 Encoder Host (QAM & ASI out)
Drake EH24 Encoder Host (QAM & ASI out)
EH24 Encoder Host
The scalable Drake Digital EH24 Encoder Host features six bays fitting any combination of SDE24 and HDE24 modules, all within in a 2 rack unit (RU) chassis. The EH24 system can encode up to 12 analog video inputs when fully populated with six SDE24 Encoder Modules. The EH24 can multiplex the encoded video streams and output them via an integrated 1GHz QAM modulator and/or an integrated DVB-ASI port, to transmit the digital video over the network.
The EH24’s sophisticated transport stream multiplexer can combine any or all of the program streams from the Encoder Modules. The operator may select what programs to include in the QAM output channel and, 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 EH24 and installed Encoder Modules are powered by a highly efficient, integrated switching power supply.

EH24 Encoder Host Technical Specifications |
|
|
Program Filtering and Grooming: |
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. |
|
Multiplexer: |
Built in multiplexer circuitry combines the outputs of all enabled encoders in an EH24 into multi-program transport streams, one to the QAM output and one to the ASI output. |
|
MPEG Program Numbers: |
Configurable by operator. If not individually configured, default MPEG program numbers in the output transport stream will be assigned sequentially, corresponding to the encoder number. The leftmost encoder input, as viewed from the rear panel, will be # 1. |
|
ASI Output: |
Any or all of the enabled encoders may be directed to the ASI output by means of the user selectable program filter. |
|
QAM Modulator: |
Any or all of the enabled encoder outputs may be directed to the QAM Modulator by means of the user selectable program filter. |
|
Output Symbol Rate: |
1 to 7 MSps |
