Hello All
i am new to this digital content would , i would like to know and understand
the Pros/Cons of different methods of implementation of the MPEG -4 , MPEG-2
decoder is better compared to the other .
Based on my current understanding there are two ways by which the MPEG-4
/MPEG-2 decoder's can be implemented the first method is using a combo of DSP
processor and software implementation of MPEG-4/2 decoder whereas the other is
to implement the full hardware based MPEG-4/2 decoder , i think it's always
better to have 100% hardware based
decoder from performance point of view , i dont know what are the advantages of
using a software based MPEG-4/2 decoder on the top of DSP processor ..........
i would be really grateful if you guys can provide your opinions and imputs in
this regard
warm regards,
Prashant Desai
