<DIV><FONT color=#0000ff>Let me put one more question.<BR>Can we use different size of payload data to transmit in a rtp packet. I mean if we have data to be sent as 250 bytes. If I fragment this data in to packets of size 100 bytes, then only 50 bytes of data is left for the last fragment. <BR>Can we send this 50 bytes of data in the next rtp packet withought padding? </FONT></DIV>

<DIV>First of all, Thanks for the reply. </DIV>
<DIV> </DIV>
<DIV>I went through the RFC 3984, But could not find whether we can reuse the NAL Header or not(point 2).</DIV>
<DIV> </DIV>
<DIV>Also It has not been mentioned how the padding is done.</DIV>
<DIV>Can You please clarify me.</DIV>
<DIV> </DIV>
<DIV>Thanks.</DIV>
