Plus, how did you know the video bitrate of Astro Plug & Play's is exactly at 4.5Mbps?
Don't forget that Astro uses Variable Bitrate (VBR) while MYTV one is Constant Bitrate (CBR). So you can't directly compare with Astro like that.
you are confusing VBR with Adaptive Bitrate. VBR is taking one video source, and then through encoding, you will get either higher or lower bitrate depending on the scene within the same video file (the resolution does not even change).
Adaptive bitrate meanwhile is what streaming services are using. There is a manifest file that a player will read (either m3u8 or now used by mostly large companies, mpd), and it list down the various bitrates and resolution that the player can choose from the server depending on the internet speed. Each bitrate choice is encoded with CBR, since VBR is not adviseable for live encoding.
And it's easy to see the bitrate that Astro uses since Astro Go, Plug and Play and Sooka basically uses the same source. Taking the 1080p Sooka manifest you can see that the highest quality that Astro offers through streaming is 1080p 50FPS 4Mbps CBR.

if it's interlaced, you don't need until 6 or 7Mbps. 4Mbps interlaced should look similar to 8Mbps progressive. But to be honest, for the average Malaysian consumer they won't even notice any quality difference.I beg to differ. It is either you didn't notice the terrible compression artifacts during fast/complex motion scenes, or you don't watch MYTV's digital TV broadcasts often enough.
Because Josh, you are certainly not grouped in what I mean as an average Malaysian. For an enthutiast like you, yes you would likely notice that pixelations and compression issues. But whenever I tell the same things to my friends or colleague, which I would classfiy as an "average, low to middle income Malaysians", they say the picture looks fine, and to them, it's really "good".
