ASI Module: Operation and Control
The ASI Option module provides ASI outputs for the transmission of MPEG-2 transport streams.
There are no configurable parameters specifically on the ASI option module.
When an ASI option module is fitted in a base chassis the host detects its presence and adds the option to configure a transport
stream to be output over ASI. This is available in addition to the standard IP outputs.
The ASI output transport stream is configured in the same way as for IP. From the web interface, browse to:
Configure > System
> Slots > Slot n > ASI IO Option Card > Outputs > ASI Output 1 > Transport Streams
.
Configure the Transport Stream
as required (ensure output is on, specify bit rate, add components, specify PIDs etc). This transport
stream will be output on both ASI outputs. There is no option to configure the outputs separately.
It is not possible to automatically set a transport stream to be output over both IP and ASI. Each output stream must be
individually configured.
External Sync Module: Operation and Control
The External Sync Input card enables the units internal 27 MHz System Clock Reference to be locked to an external clock source.
There are no configurable parameters on the external sync option module.
To configure the external sync input to be used as the clock source, from the web interface, browse to:
Configure > System >
Base Unit
The drop down list for MUX SCR source provides the available source clock options.
If the external sync option module is not fitted, only internal and video options will be available.
GOP Structure
Sets the number of B frames between reference frames
Scene Cut Detection
Configuration to minimise affects caused by scene changes
Reflex
Reflex license required to enable configuration
Seamless Buffer Delay
Buffer Delay for Reflex operation
Min Seamless Bit rate
Min bit rate for reflex operation
Lookahead Delay
The time between the lookahead encoder estimating the
required bit rate and the final encoder encoding that piece of
video.
Profile
Defines the profile to be used for the encoding
AU Ctrl
Controls the data put into the TS for video Access Units (AU). This can
be Random Access Indicator (RAI), AU info (ETSI 101 154) and Time
Code (TC).
