Encoder Default setting. TS Source:
This option enables a choice
of which MPEG transport
stream source is to be
transmitted.
ASI External ASI BNC input.

This is an alternative AAL-5
transmission mode.

Srce Clk Tolerance:
This setting affects the
reception clock recovery
tolerance to the source
transmitter clock accuracy,
normally set to Normal.
If the source clock is known to be accurately calibrated to either the PAL-I or ATSC specification then those
settings can be used, resulting in less end-to-end delay.
Min: 0 µsec
Max: 4000 µsec
Step Size: 1 µsec
The maximum ATM network Cell Delay Variation of the MPEG transport
stream that can be tolerated (in micro (µ) seconds).
CDV Tolerance:
This setting affects the
reception clock recovery
tolerance to cell delay
variation introduced by the
ATM network.
Cell Delay Variation – a
component of cell transfer
delay, induced by buffering
and cell scheduling.
Configure it to a value greater than or equal to that specified by the network operator, to handle the worst case
but to also achieve the minimum possible end-to-end delay.
CAUTION…
Excessive end-to-end delay may cause annoyance when, for example, live reporting
requires an interactive conversation with the studio. Long pauses may occur as the
recipient waits for the reply.
Active The transport stream ASI output is enabled. TS ASI Output:
This enables the TS Asi
Output to be changed.
Not Active The transport stream ASI output is disabled.
0 Byte mode ASI Stuffing Bytes:
This enables the ASI Stuffing
Bytes to be changed.
1-7 Bytes for Burst mode
