What will the impact for this change. Improvement in picture quality?

No. They can accommodate more channels on this frequency

 

[IndianMascot]

Oh. That's cool.

zing update Deepu bro
IndianMascot bro, they converted the modulation technique for sending/receiving the signals.

What does that mean

Thanks for the update Deepu bro

This page describes 8-PSK modulation basics or multilevel PSK modulation which is a type of digital modulation based on carrier phase change.

In Phase Shift keying modulation or PSK modulation phase of carrier is changed according to the digital data. It is digital modulation technique. It is used in broadcast video systems, aircraft and satellite systems.

We can achieve bandwidth efficiency when we represent each signal element to map more than one bit.In BPSK modulation digital data of 1 and 0 is represented by 180 degree phase change. In QPSK by phase shift of 90 degree, here 2 bits are mapped on each signal. In Multilevel PSK more than 2 bits are mapped using different phase angles. In 8-PSK eight different phase angles are used to represent bits, here 3 bits. Figure below shows constellation of 8-PSK signal.

Ok. So basically it improves signal bandwidth
