[Mp4-tech] need Help regarding MPEG-4 AVC within MPEG-2 TS

[Prashant Desai]

Hello All 
   thanks a lot to all of the members on this lists ,   for all the help & guidence that you guys have provided to me ,  i would like to know following things WRT MPEG-4 Part to and MPEG-2 
1)  We came to know from few companies thats are dealing in the MPEG domain that
  MPEG-4  Part 10  content can be transported  over IP  by encapsulating  the same with in the MPEG-2 transport stream ,  is this true ?   if  it's true then  please guide me on 
To decode this MPEG-4 Part 10 content which is encapsulated with in the MPEG-2 TS  do we require both MPEG-2 and MPEG-4 part 10 decoder on the IP Set Top BOX  ?    if so
 then do we need to pay for the royalty for both MPEG-2 and MPEG-4 part 10  ?   for the content etc ?
2)  what are the other options to transport MPEG-4 Part 10 content over IP transport ?  apart from encapsulating it within the MPEG-2 TS ?  cant we directly transport it over IP  without using MPEG-2 TS  ? 
3)  As far as the service provider of IPTV is concern i  think MPEG-4 licensing is far more cheaper compared to the MPEG-2  ,  is this statement true or false ?  why ?  what are things that service provider is required to considered while estimating the cost of deployment thats related to MPEG-2 and MPEG-4 part 10 
regards,
Prashant Desai
