Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual
6.2 SD Encoder Cards
There are three types of SD encoder available, briefly described below. The selection of encoder card is principally based on
functionality required. The type of hardware encoder that is plugged in will automatically be detected and reported in the GUI.
The options presented to be configured will be adjusted to only those available to the specific installed encoder.
6.2.1 NXP
•
Available as single and dual channel encoder card.
This is the legacy SD MPEG-2 encoder model for both ETSI (European standard) and ATSC (North American standard).
It is no longer available for purchase but may be encountered in existing installations. This encoder supported fewer video
resolutions and audio bit rates than the current VWEB encoder. It also did not support Closed Captioning.
6.2.2 DV1CE & DV2CE
•
Available as single and dual channel encoder card.
This is the currently shipping ATSC SD MPEG-2 encoder with support for a wide array of video resolutions and AC-3 audio bit
rates. There is support for ATSC closed captioning which may be turned on or off as required.
6.2.3 DV1CEM & DV2CEM
•
Available as single and dual channel encoder card.
This is the currently shipped PAL SD MPEG-2 encoder with support for a wide array of video resolutions and MPEG-1 audio
bit rates.
6.3 HD Encoder Card
There is a single channel HD encoder available. The type of hardware encoder that is plugged in will automatically be detected
and reported in the GUI. The options presented to be configured will be adjusted to only those available to the specific installed
encoder.
6.3.1 DV1HDA
•
Available as single channel encoder card only.
This single program HD/SD encoder supports both MPEG-2 or H.264 encoding. The following table outlines the multiplexing
capabilities for HD encoded programs per QAM channel or IP multiplex.
FYI:
It is important to note that the Video Resolution of this card must be set to match the input
source.

FYI:
The ability to output 5 HD programs per QAM depends on encoding format and bit rate. The
DigiVu and DigiVu CD may be limited to just 2 HD programs per QAM with a high encoder bit rate
setting.
6.4 Input and Output Cards
There are other cards available that may be used for some specialty applications. The cards are briefly described below.
6.4.1 DVDMQMB & DVDMQMAC QAM Demodulator
This card must be used if an add/drop configuration is required. May be installed in any card slot except #1.
6.4.2 DVGIGE Gigabit Ethernet Output
This card is used in applications where Ethernet output of the DigiVu is required and is supported only in specific slots. The
recommended slot to use is always the highest available which will usually be slot #2 in the DigiVu Mini 1RU model and slot
