Now The Question Comes As To Whether TATA-SKY Will Be Able To Add Many More Channels" Including The HD Ones, Once The GSAT Ku-Band Transponders Become Operational?

We Know GSAT-10 Has 12 Ku-Band Transponders, Just Like The INSAT 4A. The Number Of Channels That Can Be Crammed Into Each Transponders Is Fixed, And Is Unlikely To Be Any Different From The INSAT 4A, Unless The Bit-Rate For Individual Channels Is Drastically Reduced. So How Would TATA-SKY Be Able To Accommodate More Channels Once It shift's To The GSAT-10?

How To Add More Channels Without Reducing The Bit Rate For The Existing Channels?

Any Idea Please Reply !!!

Compression tech Also evolves almost every year, just look at 4K. When it was invented it cannot be broadcasted via sat bcoz it required so much bandwidth but now 4K chs required only 2-3 HD chs space. I think if TS use h.265 then they can add 110+ SD chs on same 36 MHz tps as H.265 gives you double the data compression ratio compared to H.264/MPEG-4 AVC at the same level of video quality.

So to increase bandwidth to add chs you can do two things, either invest on satellite transponder or invest on Compression. It's a matter of preference which solution you want ;)

I don't think migration to H.265 will happen anytime soon. For one, TS is just about to complete migration to mpeg4 and look how much money, time and effort has gone into it. Complete move to H.265 / HEVC will require more investment and more importantly another round of replacement of all STBs. Not happening so soon! :no

Secondly, as far as I am aware there is no DTH provider in the world completely on H.265 / HEVC yet. 4K has not yet gone mainstream anywhere in the world.

For transmission of more numbers of the current technology mpeg4 SD and :HD channels, other than getting more TPs, I think best option is to use frequency reuse technology to activate dual polarity. Of course it remains to be seen what happens. As of now TS is OK in terms of free space available in its set of 12 TPs.

Wow, with freq reuse along with H.265 they can add 200+ SD chs in 36 MHz :lol

Yeah. With technology advancement, anything is possible! ;)
 
So only after this migration we can espect new channels
