AVC/H.264's SI/SP Frames?

[aketon]

Hello there,

Can anyone please tell me what are the SP and SI slices in the Extended Profile of AVC???

[ac-chan123]

have a look at the docu at http://bs.hhi.de/~suehring/tml/ and the last draft H.264 draft at http://bs.hhi.de/~wiegand/JVT.html.

as i wrote there the faq is not the place to discuss avc/h.264 issues -> thread split

SP/SI are transition frames, used for bitrate scalability purposes.
Using these transition frames it is possible to switch between two streams without breaking the decoding precision (like it was ofted used in MPEG).
A good toutorial can be found on
