------------------------------------------------------------------------------------
I try to use this command as below:
/dvbsnoop -if test.ts  -n 500 0x10

but I didn't get the similar result like example 

what kind't command should I input to get the similar result like example?
I can sure that the test.ts file has NIT information.

Thanks
Ye Hui
