  Hi Prashant, 
     Software based codec has following advantages, 
          i)  Code can be ported across many platforms without any change or with minor modifications if required. It gives better re-usability and time-to-market 
          ii) General DSP or RISC processor in a system, can be used for other codecs (audio etc) also.         
          iii) Software updating will be easier than hardware modification.           
   Please correct me if my understanding is wrong!

  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
