Some ramp up of bitrates should improve video/audio quality, but financially it would be not advantageous to MYTV as they can sell more slots. So they rather stick to such low bitrates instead as they will have more slots by doing so.

No wonder RTM channels sometimes pixelated especially movies or fast scene. Channels on MUX 1 also sometimes like that but not too noticeable for me.

Btw do you know how much the bitrate for Astro HD channels? I'm so curious to compare between these.

No wonder since yesterday i realise my 8tv became 1080i

Wow...now can watch day and night......
Next step...4K.......

Adding a third MUX is really expensive. MYTV were supposed to install 3 MUX combiners at their sites, I don't know if they did.
You still have to add the third transmitter equipment and the extra distribution

And don't forget the additional RF channel and the (maybe) necessary channel sorting...

ps: I'd still like to see the muxes from Gunung Pulai (ch 47, 43) moved down to lower uhf band (ch 21-28). It is possible, the only thing left now is regulation and technical/cost limitations.

I mean, Hot FM, Fly FM, One FM & Kool FM still have no EPG sort to say.

I have a strong feeling that Astro uses Statistical Multiplex method (also known as statmux) for encoding its video tracks (TV channels).

What is statistical multiplexing (statmux)?
Statmux is a technology that allocates bits in real time among multiple live video channels, combining the encoded outputs into a multiplexed program transport stream.
Statmux instantaneously adjusts the bitrate of each channel in the statmux pool to make the best use of total available bandwidth.
This maximizes network efficiency by optimizing picture quality for a group of channels within a fixed total bandwidth.
Just self-imagine that the "HD HEVC" shown on the animation is "HD AVC (H.264)"
Animation source: https://aws.amazon.com/medialive/features/statmux/

Statmux refers to the video bitrate that not just automatically fluctuate/spike into higher or lower bitrate depending on the movement or changes of the particular video scene (like variable bitrate), but it also influences with other channels within the same mux or transponder. Therefore, there is no fixed video bitrate for Astro.
It's like, let's say if the channel now doesn't have much movement, it could go between 500kbps or 3Mbps, but when there is movement or fast movement, it could fluctuate between 3-6Mbps or over 6-8Mbps.
Unlike MYTV Broadcasting, their bitrates are almost or indeed constant. If they set 4Mbps for HD channels, then it'll be 4Mbps all the way, and doesn't fluctuate at all regardless of scene changes whatsoever.
So there is no "fixed" and definite answer to your question And I would say it will be unfair to directly compare with Astro and MYTV, because the way they deal with the bitrate encoding are different, and both has its pros and cons.

I'm sure MYTV have its "spare" muxes on its transmitter sites.

In your opinion, which one is more costly in terms of overall?

Operate more mux
- Existing viewers will get to enjoy more channels or improved A/V quality with higher bitrates almost immediately, or just perform auto/manual search if necessary. No need to change new receiver if all channels continues to use H.264 video codec.
- Every centralised antenna systems (MATV) used in buildings like apartments/condos must carry out upgrading/reconfiguring works to be able to receive signals from more muxes. Proper planning and preparation is needed.
- Using more mux means more transmission equipment + more electricity to be used in transmitter sites, which could increases operating expenditure (costs)?

Broadcast all SD and HD channels using HEVC video codec
- Just like being implemented in some European countries.
- The STB/receiver/IDTVs used by every viewers must support HEVC, or they'll have to buy new device to continue watching DTT, and this could especially impact viewers from low income families.
- Could offer much better picture quality and/or increase number of channels by using lesser number of muxes (compared to H.264).

The modulator and power amplifier are expensive. You will need new filters on the combiner every time you retune the channels as well.

Singapore is sitting on the entire 500 MHz block, which blocks Gunung Pulai being tuned down. Malaysia is getting squeezed on spectrum as the top end is given up to 5G, some serious negotiation with Singapore is needed, they should give up some of their block in exchange for the 5G

Though it would be nice if they give equal audio bitrates to mux A for matchinng the quality over mux B one firstly.

I really appreciate your knowledge and technical details. Not many of us can get all the data. Now I understand both are implementing different types of settings. And of course Astro for being a paid broadcaster have to be really "smart" in squeezing the channels in 1 transponder.

I guess, in my early understanding:

1. Astro and unifi TV customers can only watch the supposed "DidikTV KPM" channel as a preview via ntv7, hence not getting the 17-hour channel for both pay-TV services instead. Especially for Astro, cuz yeah they've got their own Tutor TV though.

2. IDTV users will get the channel, but those who cucuk myFreeview decoder on old TV sets cannot.

I'm dizzier when typing this.

Really, many questions.

I also wonder what will happen on the NTV7/DidikTV KPM channel on 17 Feb. How about the existing programs on the channel? (News slots, some informative programming, Running Man) Where will these programmes go?

How about the playout? Will it handled by Media Prima playout centre on Sri Pentas/Glenmarie?

How about the ownership structure? Will it be a JV between Media Prima/Ministry of Education or slot renting from Media Prima? How about the fate of the NTV7 channel?

Rescan is not supposed to be needed as it will automatically appear on the NTV7 slot.

Are they really axed ntv7 altogether? Is this "rebrand" exercise temporary till MCO ends and will revert to ntv7, or permanently becomes a fully edutainment channel? Holy moly

Source from SoyaCincau - NTV7 becomes MOE’s DidikTV channel from 17 February

The irony thing is, they did not explicitly mention what's gonna happen to existing Wow Shop slots, as well as a few handful of regular programming like Running Man. That's how the confusion arises.
No no... Don't get confused by that statement of telling you to rescan channels whatsoever. I think that is to let the public know how to get NTV7 channel via DTT in general only.
The way I see it, previously NTV7 airs Wow Shop almost whole day, leaving only the few hours slot left for some regular programming and prime time news bulletin.

Actually Wow Shop now is pretty much like "renting" airtime on NTV7 channel to air its home shopping stuff. So I guess that this upcoming Didik TV shall be no much different.

Fate of NTV7 channel? The channel is pretty much half dead since the day they air almost whole day of Wow Shop years ago. I think from 17 Feb 2021 is, all or almost all Wow Shop slots in NTV7 that we all know today, will be replaced to Didik TV slots.

I think MOE decided to rent TV slots on NTV7 rather than having a dedicated educational channel, likely because it is cheaper than creating a brand new TV channel. You see, NTV7 is already a TV channel that are well known to all Malaysians, and Astro, Unifi TV and DTT already have access to that channel. So it is like using existing resources that can easily reach more viewers. Cheaper, yet can reach more viewers No channel rescan required whatsoever.
Why emo anyway? NTV7 channel is pretty much half dead since the day they air almost whole day of Wow Shop years ago. Now, MOE is just renting TV airtime on NTV7 for its edutainment content for primary/secondary school students.

It probably because Media Prima sees that this brings them another source of income (their client is MOE), so they "give up" Wow Shop slots in favour of the MOE. After all, for those who love to buy Wow Shop products can still tune to the dedicated Wow Shop channels CH104/106 on DTT, or you can still watch them on TV9. LOL.
Could that means, Media Prima doing this as their efforts of corporate social responsibility (CSR) as opposed to almost whole day of Wow Shop? Maybe.
But the thing for sure, by doing so wil definitely help students who have lack access to Internet to be able to get primary/secondary schools lessons, which is also a need for the students too, especially during this ongoing pandemic.

If Media Prima sees this as their good source of income, or who knows MOE pays better than Wow Shop in the long run
This could potentially become permanent even after COVID-19 pandemic is over in Malaysia someday.

I mean, we have channels like Awesome TV, TVS and a few more upcoming channels to come on DTT platform. So those shall acts as an good alternatives for good TV programming.

I assume ntv7 would be in HD (over DTT) later on after the Didik TV slots would be getting use to.

ntv7 was awesome after all. We're watch drama, news, entertainment, current affairs, movies and more. ntv7 will be no more and rest of it as always save on the internet as archive. Thank you for the years ntv7, well miss you for now as 23 years. #FsInTheChat everybody, if you remember this ntv7 because analogue TV was dead since October 2019. Salute to ntv7, you always feel us as feeling good to entertaining with us. DidikTV KPM is better than ntv7 on Wednesday 17/2/2021 @ 7:00am. ntv7 (part of Media Prima Berhad) will be cease to exist.

Sorry to destroy the "SPM mood" on NTV7's Didik TV slot, but I find this very very disturbing



If you are the actual student looking at this post, sorry to offend you la. I just can't un-see this. NTV7 make your faces look terribly wrong, because they use the wrong aspect ratio.
Even if the Google Meet video call feeds isn't in HD quality, at least the tech guys at Media Prima should have display it in 16:9 aspect ratio instead of force stretching/fit to screen from a 4:3 aspect ratio video resolution
If my face were shown on their wrongly configured aspect ratio TV screens, I will be super freaking mad Make my face look damn fat like hell

I notice that the UI on the Google Meet seems to be very big, so I guess they use a computer with a display resolution of 1024x768 (or worse, 800x600). Bad decision indeed.
There are many 16:9 aspect ratio display resolutions can be used, such as 1280x720, 1366x768 or 1600x900. Just don't make stretch their faces like that laa aiyooo
