Based on Ministry of Finance, it costs the government RM 254.4 million for the right to use 1 MYTV multiplex, including the facility, transmission services and technical support, for 3 years, as a result of direct tender. (In this case, even without direct tender, it is very likely that MYTV will still get the tender anyway) This translate to RM 84.8 million each year for the right to use the multiplex.

It is no wonder why other government linked TV channels like Bernama TV and TV Alhijrah, also moved to Multiplex 2 in addition to RTM (which is itself the public broadcaster and government department).

Imagine the annual DTT transmission cost imposed to Media Prima. It is no wonder Media Prima doesn't currently plan to bring 8TV in HD given their current financial situation.

According to Digital News Asia https://www.digitalnewsasia.com/deep-dive/t...nally-hits-road
Bandwidth per SD channel is 2.5Mbps while per HD channel is 4Mbps.
Hmmmm

Then, from the date where Mux 2 is up on air, plus 3 years period... That's when the "direct nego" deal between gov and MYTV ends...
So, RM84.8 million per year, entire DVB-T2 multiplex for the government, is it good or not good? Too cheap? Too expensive? Or how? What do you think?

7m for a 4Mbps HD channel doesn't sound right...unless they "could" bump it to 5Mbps.

You say it doesn't sound right, but MYTV say "it's seems fine to me".

So indirectly, they are implying that you are the one that is "not right".

You:

Ok that means when mux 2 started its owned by the government and not MYTV (but still in MYTV umbrella)? (your wording looks like the govt have to lend space on mux 1 before mux 2 starts)

Even before the migration to MUX 2, RTM will still probably need to pay transmission fees to MYTV in order to broadcast on MUX 1.

MYTV still owns the frequency and multiplexes and are responsible for technical and transmission part. MYTV's configuration are 3 main + 1 standby multiplexes on each transmitter.

However due to cost issues and small amount of channels, only 2 of 3 multiplexes are in use. And the existing multiplexes are not full at all according to MYTV's recommended bitrate.
Both multiplexes would just barely full if MYTV is using full VBR/variable bitrate (MYTV is using VBR but the fluctuation of bitrate is so little that it is CBR/constant bitrate in practice) + recommended bitrate of 6Mbps per HD channel and 2Mbps per SD channel.

If the government doesn't lease 1 multiplex from MYTV for their own requirements, we probably won't have MUX 2 at all/MUX 2 activated well after DSO.

Thank PH gov on that.

Now on air
707 HOT FM
708 KOOL FM
709 FLY FM
710 ONE FM

The audio sound like low bitrate (except hot fm)

I guess it is in right price
Considering broadcaster get

4mbps for T2 S2 (KU & C) 3 platform

New radio channel additions are on MUX 1.

The audio bitrate for 4 newly added channels are HE-AAC V2 Stereo @ 32kbps. Much more inferior than online streaming (which uses HE-AAC V2 48kbps) Note that RTM radio channels on DTT uses considerable higher amount of bitrate to sound better.

Why uses 32kbps and 48kbps when a much higher bitrate could be used for higher audio fidelity? MYTV is cheating in terms of "high quality audio" which in fact isn't (except RTM radio).
HE-AAC V2 is designed for mobile streaming use so that the users will be able to stream live radio in reasonable quality + saves broadcaster internet bandwidth. This means lesser interruption on live streaming.
It is not designed for broadcast use but nevertheless many TV and radio broadcasts are using that.

For your comparison, Media Prima's TV streaming uses 128kbps AAC Stereo.

Perhaps joshhd will do the bitrate check after new channel addition? But the increase would be quite minor nevertheless.


Within the spoiler this shows the audio quality of all 4 audio channels:


This could explain why for now, Media Prima's radio channels on DTT (except Hot FM) sound like s***.

I have included an attachment file for the audio quality on all 4 channels.

Malaysia Digital TV Bitrate Check
28 Aug 2020

MUX 1: 666MHz (Channel 45)


MUX 2: 650MHz (Channel 43)


Indeed, the audio bitrate for the new 4 radio channels is in Stereo 32kbps HE-AAC v2.

I suspect that the issue come from the source itself, either Media Prima side or before MYTV distribute the radio channels to viewers nationwide...
The overall audio quality of Stereo HE-AAC v2 32kbps sampling rate 48KHz that I know, the difference is like day and night compared to what you guys heard on the 4 new radio channels.
So I am very sure that something wrong somewhere with their audio settings before distributing the radio channel to viewers.

Dear MYTV/Media Prima engineers, kindly go and check all the audio settings properly from A to Z
Honestly, MYTV just don't care.
You want more bitrate, you pay us more money, then we provide you more bitrate.
To them, bitrate = money

As you can see on the bottom right corner of the screenshots attached, bandwidth used is now about 26Mbps.
Each MYTV mux (256QAM) has a maximum bandwidth of 34Mbps. You can imagine how many HD or SD channels or radio channels remaining that they could still add, before putting MUX 3 on air.

Or just improve whatever that's on currently, especially the EPG.

Yup, the audio spectrum of 32kbps HE-AAC V2 will reach around 16khz (of course with fake treble). Something must be gone wrong on either Media Prima/MYTV or both sides. Moving to 48kbps HE-AAC V2 won't cost as much right?

The current settings on these channels are on something called AM Stereo with max 6khz audio bandwidth.
If settings were done correctly, the audio quality of Fly FM on MYTV will beat the bad sounding audio caused by excessive processing on Gunung Pulai FM transmitter.

imo Should just reduce the bitrate/resolution for Go Shop/CJ wow shop as why you need best resolutions for shopping?

And bump all audio channels to 128k for better quality.

Or maybe, they only set the bitrate of 32kbps, but they 'missed out' others like sampling rate, AAC audio codec types (AAC-LC, HE-AAC....) and so on.
Hope this is just temporary...

You know what?
MYTV always boasts themselves, saying that its digital TV broadcasts is better than analogue TV broadcasts as it offers high quality audio to the viewers...
As you check on the audio bitrate, it is utter nonsense.

Source: https://myfreeview.tv/

Forget about the surround sound first.
Stereo HE-AAC v2 at 32kbps, and they call it "high quality audio"? They got fever somewhere, is it?
It seems to me that like as if some "sales person" convinces them that HE-AAC v2 is very good, provides good audio at very low bitrates, hence save bandwidth...
Words like this, raises their eyebrows.
Because MYTV seems to me is, whatever costs that can be saved, they will save it to the very maximum.
Quality? Just put the blame on the customer (digital TV box got problem, must be not certified by MCMC, antenna didn't adjust properly, and so on)

They can't hide about the bitrates man.

The audio quality on analogue TV broadcasts has the same audio quality as FM radio.
So in your opinion, do you think FM radio audio quality is better, or 32kbps HE-AAC v2 is better?
They should wear earphones to listen and compare.

And, another interesting find here...

So I looked at @joshhd 's post on mytv bitrates and the program used is TS Analyzer.

I loaded up my Singapore TV recordings from K2 DVB-T2 STB and I saw the bitrate for video is only 2-3Mbps!

And yeah few megabits for 'other' data... But why when I record the STB tell me it's 8? Where the remaining 4Mbps gone???

Well, I'm mistaken...

A retry to verify the bitrates tells me it's 7Mbps now, probably TS analyzer used ISDB for auto mode in a DVB TS file.

Lol... I was shocked for a second though...
If your digital TV box can perform TS record, that will be better as it gathers every data that is present in the frequency.
Try look on menus like MENU>Tools>Record (TS Record, sometimes also known as TS Capture).

According to the German Fraunhofer Institute (the inventor of AAC codecs), they claimed that 32kbps HE-AAC V2 provides good quality audio. MYTV may have taken advice of this and uses 32kbps, despite MYTV has the option to use higher bitrate. Obviously, a minimum bitrate of 128kbps AAC sounds better (this is the recommended bitrate). Sometimes, the compression artifacts could be masked by adding additional processing to make it sounds less worse.

If low bitrate has to be used, the minimum bitrate used should be at least 48kbps HE-AAC V2 , which is what this codec is designed for. This bitrate is a good compromise between low bitrate and high quality audio.

A little bit off topic here as this already involved radio:

Audio quality on radio depends on the amount of compression used, compression preset on transmitter and the quality of incoming audio feed (such as WAV, FLAC, High bitrate AAC or MP2). Note that radio stations no longer uses analogue feeds to feed audio as it will introduce additional hissing during delivery of audio from studio to transmitter/control center.
Usually, a good/very good FM stereo reception would certainly beat any low bitrate HE-AAC/HE-AAC V2 streams in terms of audio quality, as long the audio feed is good and a correct amount of audio compression is used.

The audio compression on Astro's radio stations sounds loud yet clean as they are using one of the best audio compressors on the market (Orban Optimod). If wrong amount of audio compression and preset is used (such as Fly FM on 102.5 Mhz on Gunung Pulai), the audio will sound really awful. In this case, even 32kbps HE-AAC V2 audio on MYTV would sound better than FM.

A very big chunk of MYTVs fees probably end up with TM, they own most of the sites, control maintenance access and the distribution network.
TM used to make a fortune from the analog TV transmitters, count the transmitter towers at Genting and Bkt Sg Besi
