[Mp4-tech] Simple question for simple profile levels

[岡本光平]

Hello Everyone
I'm currently in a mobile phone developing project,
and this phone device is expected to work as a media player.
It's about to support MPEG4 , simple visual profile L1.
However I'm wondering whether a "simple visual profile L1 support"
covers the lower level (L0) or not.
Does the simple visual profile levels have lower compatibility?
Regard,
