live stream

[for a pound]

I have the nexus 7 and can watch what ever is on the HDD of the nexus 7 through air sync double twist either through my Xbox or my panaonic et5 viera TV
Was just wondering if I could stream live content as in watching sport or YouTube from my nexus 7 to my TV with out having to buy a dongle
My brother has the note 2 but had to buy a Samsung dongle so he could do it
Thanks
