thanks.
Moreover, I have read this: "The SFP* corresponds fairly well to a
Packet Error Ratio PER = 10-4 after the RS-decoder at the demodulator
TS-output"
So, i think, for criteria SFP it is also possible define a PER target
(measured by a TS-MPEG analyzer) without looking at the video/audio
output.
*SFP = Single Failure Point

this usually means just what it sounds like, a visable error that
shows up on the reconstructed video.. nothing more fancy than that

Hi all,
I'm a student and i have to do a research about diversity reception in
DVB-T.
Now i'm reading an article from this link:
http://www.dibcom.com/Images/Upload/pdf/Publications/Confluent.pdf.
I don't understand the subjective failure point definition (page 4) :
"maximum of one visible MPEG decoding error during 20 seconds".
Please, i would like to know what does this definition means; in
particoular, can i look for "visible MPEG decoding error" analyzing
the audio/video stream (at the output of the STB) ? Or they can be
detected only with the use of an MPEG-TS analyzer ?
Best regards
