<P class=MsoNormal style="MARGIN: 0in 0in 0pt"><FONT face=Arial size=2>Earlier video compression standards were always centered around the concept of a bit stream. Higher layer syntax elements were separated by start codes to allow re-synchronization to the bit stream in case of corruption—be it the result of an erasure or of bit errors.</FONT></P>

<P class=MsoNormal style="MARGIN: 0in 0in 0pt"><FONT face=Arial size=2>H.264, when employing its optional Annex B, also allows such a framing scheme, primarily to support a few legacy protocol environments such as H.320 or MPEG-2 transport. The RTP packetization, however, employs the native NAL interface that is based on NAL units (NALUs).</FONT></P>
