Field Explanation
Active Stream Displays Active Transport stream.
ASI Input If the ASI input is present with no errors, a green box with the word PRES appears
under the label. The area under the label remains blue with -- if input is absent.
Bitrate (Mb/s) Displays total transport stream bit rate for each ASI input.
Switch Elapsed Time (s) Displays time elapsed since switchover.
Switch Count Displays the number of switchovers since last reset.
Timestamp Type Indicates mechanism for synchronizing output of transmitters signaled by
T2 gateway (see TS 102 773 section 5.2.7). Only required in T2MI mode.
Relative = timestamp only contains time of emission relative to next 1
pps (subseconds)
Absolute = timestamp includes absolute time of emission
Null = timestamp packet detected, but no timing alignment required
N/A = no timestamp packet required/detected (MPEG-TS mode)
Processing Time Internal processing delay of modulator. This value is used in planning of
SFN network timing. Processing time is delay from reception of L1
packet (end of T2 frame) at transport input to I/Q data ready into SFN
delay memory.
