bandwidth consumption<BR></FONT><BR></DIV>
<DIV></DIV><BR clear=all>Hi Sergio,<BR><BR>I know that the bitrate depend from
information content of source. I use VLC as source that transmits still image
CIF picture with 1 fps and format YUV 4:2:0.<BR><BR>At the moment I'm not
interested in quality, but only in video bandwidth consumption.<BR><BR>I have
taken in account the sixth column IP BW of Wireshark capture file and with
Matlab I have extract the Probability Density Function. The mean and max
bandwidth values are very high respect how I'm expecting.<BR><BR>I would like to
know what can be the total video bandwidth with H263p codec and H264 codec of
CIF picture with 1 fps and format YUV 4:2:0?<BR><BR>The values that I have
measured are strange for me, but I can't find documentation about video
bandwidth as this <A
