Dear Sowmya,
I am rather confident that you can find the answers to your questions in 
either ISO/IEC13818-7 or ISO/IEC14496-3. In the case you have 
difficulties to find the answers in these documents or if you have 
doubts with regard to the specifications please do not hesitate to 
contact me again.
Best regards,
Ralph
