So doesn't that mean that if the device supports mp4, it also supports H263 Profile 0 Level 10? Since the H263 is mandatory, and device that supports mp4 means that they opted to include the optional protocol???


To meet the 3GPP standard, H.263 Profile 0 Level 10 codec has to be supported, ie. it's mandatory. As an optional also these other two codecs may be supported.

Only MPEG-4 codec may be supported, but then it's not according the 3GPP standard.

Pardon me, but the last time I checked... the word SHOULD means it HAS TO include the said formats.


Here's a link to a document which descripes how you interpret the different words in the specifications, http://www.ietf.org/rfc/rfc2119.txt
