Ipad mirroring or streaming for quality

Question

I now have two ways of streaming music and movies from my ipad and i phone.to my speakers and tv.
Both use appletv.
One is to connect using airplay and the other is to use mirroring.
Is there any difference in the quality of media when these methods are compared?
Thanks

Video buffering can be adjusted at client side within your
SWF file,
which plays FLV.

It is easy to do the same using special bandwidthmeter. I saw
several
such SWF-based tricks, which all loads a file of known size
and
measure downloading time. Then you can switch between
different video
sources depending on the the calculated bandwidth value.

And this is also doable by simple PHP script, delivering
video file to
your client. Just create a file reading cycle with short
pauses within
it, defined by the average delivery bandwidth preset value. I
use such
method and it works really good for a more or less stable
cable
channels. The only disadvantage relatively to true streaming
is that
such method works not so good with VBR streams. Because it
has no
information about real bitrate of each portion delivered.
Therefore
you need to add some extra bandwidth portion for some
unpredictable
delivery issues. E.g. if your video has 256 kbps and your
audio has 64
kbps it doesn't mean that your total bandwidth preset value
should be
320 kbps. It should be done a bit greater, for example 350 to
380
kbps. That will work for any case.
