SMPTE 333M, then the Encoder’s RS-232 port through which the
data is to be input must be selected.

!SMPTE 334 CC can be extracted from the HD-SDI.

For more details regarding setting up the Encoder’s closed caption
options see the Reference Guide.

4.7 Set the Audio Options

The standard Encoder can process two stereo pairs, but up to four can
be processed with the addition of audio option cards. All the audio
inputs are configured in a similar manner.

Navigate to the Audio Menu. Select the following options:

!Source Option - select the audio source. This can be an analogue

or a digital input, or can be de-embedded from the SDI input. If the
audio source is embedded in the SDI (HD or SD) then the audio
DID must be set. Entering 1024 for the DID causes the default DID
for the selected group to be used.

!Coding Standard Option - Select the coding standard, e.g.

MPEG Layer 2, Dolby Digital (AC-3) etc.

!Bit-rate Option - select the required audio bit-rate.

4.8 Set the Data Options

Navigate to the Data Menu. If serial data, either RS-232 or RS-422, is to
be encoded then configure the input source and bit-rates.

4.9 Set the Output Options

The Output Menu allows the output of the Encoder to be selected. This
is set to ASI unless an option card providing an alternative output is
fitted. If the output is set to ASI, a Delivery Descriptor Menu is
available, which allows all the parameters in the delivery descriptor to
be set.

4.10 Configuring Option Cards

For information regarding configuring any option cards that may be
fitted to the Encoder please refer to the Reference Guide.

4.11 Configuring the Encoder for Minimum Delay

There is a trade-off between encoding delay and picture quality for a
given bit-rate. The parameters that can be adjusted to reduce the
encoding delay are as follows:

22

!Clock Source - the Clock option is found in the Mux Menu. Setting

the clock source to either HSYNC or Video, means that the frame
resynchroniser in the video input of the Encoder is not used, which
removes between 0 and 40 ms of delay.

!Compression Mode - the Compression Mode option is found in

the Video Encoder Menu. There are three compression modes in
SD that reduce coding delay; Low Delay, Very Low Delay, and Mega
Low Delay and one in HD mode: Low Delay.

Low Delay mode reduces the size of the video rate buffer, which
results in a smaller encoding delay. This can compromise video
quality in some circumstances.

Very Low Delay mode also reduces the size of the video rate buffer,
but it also forces the GOP structure to IP, which removes the frame
reordering delay, and uses field pictures.

Mega Low delay mode is not fully DVB compliant. It has a smaller
video rate buffer than Very Low Delay mode, it also uses a GOP
structure of IP and different refresh techniques.

!Video Bit-rate - the video bit-rate can be set in the Video

Encoder Menu. The simple rule is that the higher the bit-rate, the

lower the encoding delay.

4.12 Configuring the Encoder for Minimum Bit-rate

The following parameters can be configured to minimise the video
bit-rate required for a given picture quality:

!Compression Mode - the Compression Mode option is found in

the Video Encoder Menu. For minimum bit-rate this should be set
to standard.

!Video Bandwidth - the Video Bandwidth option is found in the

Video Source Menu. To minimise the video bit-rate this should be
set to medium, or better still soft. However, this does affect the
sharpness of the pictures.

!Noise Reduction - if the noise reduction option has been

purchased, then there will be a Noise Reduction option in the
Video Source Menu. The higher the level of noise reduction set,
the lower the video bit-rate, but the sharpness of the pictures will
be reduced.
Three new noise reduction levels have been added in SV 3.6.0.
Please refer to the Reference Guide.

!Video Resolution - the Resolution option is found in the Video

Encoder Menu. Selecting a lower resolution reduces the required

video bit-rate, but also reduces the amount of detail in the picture.
In HD certain vertical resolutions do not support different horizontal
resolutions.

!GOP Structure - the GOP Structure option is found in the Video

Encoder Menu.

A new option, “Adaptive GOP”, has been added in SV 3.6.0. Please
refer to the Reference Guide. This option has always been available
in HD mode.

!Long GOP - if the performance upgrade option has been

purchased, in the Video Encoder Menu there will be a Long GOP
which, if set to On, allows GOPs of greater than 0.5 seconds
duration to be selected. Setting a longer GOP may allow the video
bit-rate to be reduced, but at the cost of a longer time to acquire
the service. Also, if a very long GOP is used, the build-up of noise
up to the next I frame may become noticeable.
