format the the packets ( segment - section etc...). can any body help in this regard.
Yes, in theory, you can.
Keep in mind, however, that multiplexing is a quite difficult job (this is what multiplexers are made for).
hi,
if i can suggest a starting point, there's already a free software project for transport stream manipulation; it's called JustDVb-It, the GPL licensed package we made in our previous company Cineca since 2004:
http://www.cineca.tv/labs/mhplab/JustDVb-It%202.0.html
it's a set of simple tools (following unix filosophy) you can put together in some customized ways to accomplish complex tasks.
for example, it can filter PID on a TS, swap some PIDs with others, transform python described PSI tables in sections then in TS packets, and create DSMCC carousels too..
there's a live CD to demo it with a DVB ASI port in a sample configuration (for italian MHP based interactive television)
the current version can't restamp PCR, as it's quite a complex task, but this feature is something that we are releasing RSN in our new-born start-up Avalpa (http://www.avalpa.com). stay tuned!
HTH
bye
