Yes. RTP packets sent over UDP (as they usually are) are unreliable. > So, if 'slices' (NAL units) would be delivered through RPT, can they be > lost too? > Why the 'slices' way is more reliable? Because even if one slice of a picture is lost, the other slices of the picture will get delivered, and (depending on the decoder) should be able to get rendered and displayed. > Is a unreliable transmission normal (reality)? It depends upon your network. Usually, lost packets happen infrequently. > In what object I must realize 'slices' technology? You would reconfigure your encoder to generate each 'key frame' as a sequence of 'slice' NAL units, instead of as a single NAL unit. Ross Finlayson Live Networks, Inc. http://www.live555.com/
