[ns] Can NS-2 be used to transmit real video sequences?

[galaxy-huang]

hi everyone
Recently,i am reading one book about streaming over the wireless network,today i come across such a sentence:"as well as using real video sequences and transmitting them using an NS-2 simulator-based implementation of the 802.11a/b/g MAC standard." 
My question is:can NS-2 be used to transmit real video sequences and ,if can, how to achieve this purpose?Could someone tells me about this and recommends me some book or website to refer to?
Thanks in advance!
