<div>Hi,<br><br>I would like to know what is video bandwidth consumption of CIF picture with 1 fps and format YUV 4:2:0 coded with H263p and H264?<br><br>I know that the total video bandwidth without compress is about 1.25 Mbits (CIF*bit*fps*luminance + QCIF*bit*fps*(chrominance R + chrominance B) = 355*288*8*1+176*144*8*1*2.<br>
<br>I know that H264 codec can reduce the video bandwidth up to 50-60 kbps and 70-80 kbps Ethernet bandwidth. H263p is worse than twice of H264 so requires 140-160 kbps Ethernet bandwidth.<br></div><div><br></div><div>I have analyzed with Wireshark 1.2.6 RTP->stream analysis the RTP flow. I have taken in account the sixth column IP BW with Matlab and I have extract the PDF function. The mean and max bandwidth values are very high respect how I'm expecting. For H263p 343 kbps and 555 kbps...<br>
<br>Thank in advance<br><br>PS<br>The audio bandwidth is correct. G711a requires 64 Kbps Bit rate and 87.2 Kbps Ethernet bandwidth (27% overhead) as reported here <a href="http://www.voip-info.org/wiki/view/Bandwidth+consumption">http://www.voip-info.org/wiki/view/Bandwidth+consumption</a>.<br>
