These are the DTT frequencies after frequency restacking is being carried out for Mux 1 and Mux 2.

In conclusion, the total frequency range they'll use after frequency restack is between 546MHz to 682MHz.
682MHz (678-686MHz), just right enough to prevent interference from upcoming 700MHz 4G/5G band.

Although I do hope that they would use 470-610MHz frequency range for DTT instead...

So far MYTV only announce there'll be 5 transmitters to complete the frequency retune exercise by end of this year.
The rest are still haven't announce...
That could mean the one that they just uploaded to their website, is still subject to change then? 
Will see how... 

TVS broadcasts on 1080i (HD) and on MUX 1.

Video bitrate likely on 4Mbps while audio is on the pathetic HE-AAC V2 32Kbps.

This is the first time that significant amount of Astro in house promos can be seen on outside Astro.

Wait for @joshhd for more information

For those who use MyTV decoder, may i know what resolution you all use?
I feel like once i set to 1080i, the decoder behave a bit lag on every step. Lately have intermediate blank screen and to the worse it show 'no signal' for few seconds and come back again.
At first i suspect my cable or wall connector issue. I redo everything still the same. Until i factory reset the whole decoder then back to normal.
However few days later. The screen intermediate blank start again. I wonder is the decoder too heavy for 1080 or it start to have problem already.

Both got financial back ups

From government & owners respectively 💪💵🤑
