PQ of SD channels through HDMI

[server3249]

One question to existing TATA SKY HD users. I understand that the native HD channels will come in a 16:9 aspect ratio. But is there an option to change the aspect ratio of SD channels into 16:9 ratio?

That's impossible, usless the transmission itself is native 16:9, which it is not. Most of the time 16:9 is cut on the right and left at the source and transmitted as 4:3.
