6.7 Encoder Setting
This page displays the configuration of all of the installed HD/SD MPEG-2/H.264
video/audio encoders and allows adjustment of the currently set values. If other types
of cards are installed, such as a demod or gigabit Ethernet card, they will be reported
under the heading “Encoder Type” but are not configurable on this page, so ignore
the settings reported below these cards. The
Encoder Number
control is used to
select the encoder that is desired to change the settings for, then as each encoder
is selected by way of the drop down dialog box, the appropriate encoder port is highlighted in the
Ports View
. The general
process for making changes to encoder settings is covered in the following paragraphs.
6.7.1 Encoder (port) Number:
Select the encoder port number from the drop down box representing the encoder that you wish to adjust the settings for. The
applicable/selected column becomes highlighted in
Ports View
.
6.7.2 Encoder Type:
In the ‘Ports View’ section, the type of encoder installed is indicated. The types of SD encoders that may be encountered here
were discussed in
“SD Encoder Cards” on page 6-2
as well as the type of HD encoder in
.
If another type of card is installed this will also be identified. These cards were briefly discussed in section
Disregard the configuration reported for all cards except encoders. The possible card types that may
be reported here are:
•
VWEB_NA
(NTSC Video SD MPEG-2, AC-3 audio)
•
VWEB_NA_1
(NTSC Video SD MPEG-2, AC-3 audio)
•
VWEB_EU
(PAL Video SD MPEG-2, MPEG-1 L2 audio)
•
VWEB_EU_1
(PAL Video SD MPEG-2, MPEG-1 L2 audio)
•
NXP
(Legacy NTSC/PAL Video MPEG-2 w/AC-3 & MPEG1 audio)
•
ETH1000
(GigE Output Card)
•
AN_HD
(HD/SD MPEG-2/H.264 encoding)
•
Demod_nxp
(Legacy Demod Card)
•
Demod_dnq
(Demod Card)
6.7.3 Detect Encoder (Control)
•
Slot Previously Empty
If an encoder slot was previously empty and a new encoder card was hot plugged into the slot, the GUI must be
made aware of the change as it will not take any action without instruction. Click the
Detect Encoder
button to force
a detection of the encoder card just installed. The control will be greyed out on any encoder selected that has already
been detected.
•
Slot Previously Occupied
If an encoder slot was previously occupied and a different card was hot plugged into the slot the DVIS Device must
be made aware of it but the control is greyed out. In this case, click the
Refresh All Ports
button at the bottom of
the GUI page to force the unit to detect the encoder card just installed. The control will be remain greyed out on any
encoder selected that has already been detected.
6.7.4 Encoder Active:
This check box lets you switch each encoder on and off. On the right side of the page in the
Ports View
display, encoders are
shown as active or inactive.
6.8 Input Parameters
This group of settings are for configuration of any input variables on some encoders,
such as Video Input on the HD encoder. Some of these are preset by the GUI
depending on the encoder card and in this case, is for information only.
6.8.1 Input Video Standard:
Automatically selected as NTSC or PAL as appropriate for the SD encoder card
installed. If an HD encoder is installed, this displays AN_HD.
