The Delay Variation parameter reports the variation in delay observed in a CBR IP stream, in msec.
The Seamless Protection Delay Delta parameter reports the variation in delay (in msec) between the
two streams used in seamless protection mode. This parameter is visible only his field is visible only if
Data Eth Protection is set to Seamless.
IP Encapsulation reports whether the stream received on this channel is carrying UDP or RTP
encapsulation.
Packet Size lists the number of transport stream packets per IP packet.
Column FEC detects the presence of column forward error correction packets in this input. Row FEC
detects the presence of row forward error correction packets in this input, in association with FEC Order
and FEC Period.
The Active Interface parameter indicates whether the Primary or Secondary data Ethernet is active.
Primary and Secondary IP Packets report the number of IP packets received on the data IP interface for
this channel.
Transport Stream Demux
General
Using the Program Number, Audio, Serial, DVB Subtitle, VBI Selector, and enabled sub‐controls, you
can decode a specific program in a multi‐program transport stream and select which of several
components in the selected program to decode. You can select the program to decode by its actual
program number, or by its ordinal position in the transport stream. A positive value selects a specific
program number, whereas a negative value selects an ordinal position. For example, the default ‐1
selects the first program in the transport stream (the first program listed in the PAT). The Program
Number cannot be set to 0.
Under most conditions, the decoder will select stream components (PIDs) from the program defined by
Program Number. This ensures that the correct video and audio streams are decoded as the
encoder
defined them. However, in certain applications, video, audio and data PIDs can be manually entered.
Ensure that you take great care when making manual entries to these fields.
Input Programs Table
This table presents a list of existing programs (according to the PAT) in the transport stream currently
being received. Clicking on an entry in the table highlights it and selects it for further analysis in the right
hand parameter list. The Select button copies the program number to the TS DEMUX > Program
Number parameter.
In descending order, the Program Name will be taken from the SDT table if it is available. Otherwise, the
Program Name will be displayed as Unknown.
