Nullpacket Stuffing

Requires a 

*.trp

*.trp_c

*.emc

 or 

*.emc_c

 file loaded into the "TS Player" dia-

log. 

*.trp

 files are previously recorded files.

Enables or disables nullpacket stuffing.

The output data rate of the TS

 

player equals the original data rate. The equality

ensures that the time references in the tables of the played TS stream are correct dur-
ing replay.

"On"

Activate stuffing, if you need a higher rate than the original data rate.
Null packets are inserted into the data stream.
To ensure correct time references in the stream tables, activate pro-
gram clock reference correction ("PCR, DTS/PTS > On").

"Off"

Deactivate stuffing, if you want to use the same data rate as the origi-
nal data rate.

Remote command: 

:TSGen:CONFigure:STUFfing

 

on page 68

Stop Data

Requires a 

*.trp

*.trp_c

*.emc

 or 

*.emc_c

 file loaded into the "TS Player" dia-

log. 

*.trp

 files are previously recorded files.

Ensures that a standardized TS

 

data stream is always output at the TS output at the

rear of the R&S

 

SMCV100B.

In pause or stop status, the TS

 

generator generates "test packets", which have data

and header parts, that can be configured using the 

Test TS Packet

.

Remote command: 

:TSGen:CONFigure:STOPdata
