Secret Statistics of IP DATA

 

Upon the demand of authors of satellite theme devoted articles, the "secret statistics" box has been added to IP DATA user interface. This statistics allows you, for example, to identify the stream loading. It can be useful if you want to write a satellite providers reviews, and make ratings of providers and transponders. 

 The "secret statistics" window is opened by pressing the CTRL+T keys. At that moment, the IP DATA window shall be active

 

 

 "Secret statistics" window description

"Transport stream" box displays the general transponder statistics for appropriate PID's. This statistics is accumulative i.e. the data is being collected since the moment of Prof IP DATA start.

The given screenshot shows the data of DVB-S2 STV transponder at 60E (August 3rd 2009, daytime). If we rely on statistics of PIDs, it is clearly seen that 48% of traffic is coming on a basis of PID 8191. Taking into account that PID 8191 means free space, it is able to make a conclusion that 48% of bandwidth is not used. Respectively (100%-48%=52%) only 52% of DVB-S2 STV line at 60E is in use. Thanks to the "secret statistics" you can observe the line load for other transponders and providers. 


"DSMCC decoder status" is the decoder errors statistics panel, which contains a proprietary information. It is used by PTG or teleport engineers.


"Diagram window" shows general flow speed for the chosen PIDs (active PIDs) and current PID+MAC filter. Minimal (Min), Maximal (Max) and average (Average) parameter values are mentioned. The window is fully updated within 4 minutes.  Graph values are counted once in a second.

Examples of different transponders analysis

Raduga 10957,V,5000 from 90.0E

Free 90% (PID 8191), occupied 10%.

 

 

 

StarBlazer

Free 66% (PID 8191), occupied 34%.

 Cyan diagram shows that all the significant PIDs are active. Min. traffic is 2 Mbit/s, Average - 4 Mbit/s, and Max. 9 Mbit/s. The green graph is a broadcast at PID 1365 (we don’t know what there is).
