DTT - Direct To Tablet is a Technology, That is required in the communication Infrastructure, both for wireless and wireline networking. At Least till Optic Fibers Reach Every home.
If the Satellite Broadcasting Technology and RF Wireless Semiconductor Technology, advances fast. It may be Possible for DTT as a small module in the Tablet. This is TV on Tablet with Interactivity, as we have TCP/IP as well on Wi-Fi. This method does not load the TCP/IP infrastructure with HD Videos or Audio.
The other way is Intermesh WiMax with DTH to make Interactive TV on Tablet. The HD Media is requested by a Net Protocol, then it is got form Sattelite on Local DTH and comes to Tablet over WiMax. This way a HD Video need not travel a long distance, around the globe, causing traffic jams.
I am sure, still nobody got me, or what i am talking of, but its is pleasant that way. Here is an image i had done a couple of years back. Try incremental levitation of the thought process, then you shall perceive a Tux on the Clouds.
Directly or Indirectly it is Tux who has made tablets possible in most all of the tablets you see today. They have made it happen. - In fact all are, some admit, some do not.
