I think most probably they will increase the stereo audio bitrate... But until how many kbps then I don't know... But base on the bandwidth they have, they want to use 320kbps also can...

In this case, there will be 3 audio tracks, with Stereo audio as the main soundtrack, rather than 2 audio tracks based on their press release. This is meant for maintaining sound consistency while changing channels for stereo TV sets.

The new configuration will be :

Before 3 Dec 2.30 a.m.
Main/Default audio : 5.1 Surround Sound AAC (Stereo HE-AAC on CNA)
Second audio : Stereo HE-AAC (for dual sound service)
No third audio available.

After 3 Dec 5 a.m.
Main/Default audio : Stereo HE-AAC / AAC
Second audio : Stereo HE-AAC (for dual sound service)
Third audio : 5.1 Surround Sound AAC (Likely unavailable on CNA)

Those who use 5.1 home theater systems will have to toggle themselves to the third audio track (which carries 5.1 soundtrack).

Is it just me, or RTM HD sports is quite low bitrate and low FPS, and feels like watching a web stream instead of direct feed from RTM itself.

For example watching RTM1/RTM2/TV3, the image is sharp and at 50FPS. On Sports HD, it looks like upscaled 720p around 2~3Mbps bitrate, and only at 25FPS

The last time checked, TV2 is 1920x1080, interlaced, 25FPS, average 3.5Mbps.

Wasn't it around 4Mbps?

The video bitrate on MYTV channels is really low and below satisfactory levels, that's why the picture quality will look terrible especially in fast moving scenes like in sports.
But then, MYTV would say that 4Mbps video and HE-AAC v2 32kbps Stereo audio is "satisfactory" to them, and every Mbps for them is equivalent to money.
So basically means, broadcasters got to pay MYTV more money if they want their channels to be transmitted in higher Mbps so that the video/audio would look good.

MYTV Broadcasting exists simply because they just want profit. doh.gif
They might as well invest money in something else rather than providing DTT services if getting rich is all what they want.

From a clip posted by someone here in July, the average video bit-rate is around 3.5Mbps and audio 46Kbps. The video bit-rate does sometimes peak above 4Mbps.

Edit: corrected mistake in audio bit-rate.

are you guys using a decoder box or a tv with dvb-t2 tuner build in?
i wonder if its easier to just get a tv with ready buildin tuner?
my old aunt is using a decoder box at the moment and sometimes with 2 remotes, she will accidentally press wrong button or something. will buying a ready dvb-t2 ready TV solve this problem. Less things to go wrong?

The picture quality on Singapore DTT is sometimes bad especially on high action content and during their NDP (where all channels simulcast same video), even if it has higher, decent bitrates (~7Mbps) than our DTT. It looks okay in most situations.
Malaysian DTT, it may be HD but has rather low bitrate for both video and audio, looks s*** most the time, not forgotting that syok sendiri watermark. Even some movement guarantees breakup.

Yes, just buy a new TV.

TV nowadays already have DVB-T2 built-in, so no need to worry.
And yes, using 1 remote control to control is definitely better than having 2 separate remotes, especially many elderly people would get confuse.

Do you think in the coming 3 Dec 2019, Mediacorp would do some changes on the video bitrate on top of the audio track change? Since they transmits in 3 muxes, with 2 HD channels per mux... Looks kinda waste of resource.

I wonder if they really fully utilise entire available bandwidth for each 16QAM mux for that 2 HD channels, cuz since their analogue switch off until now, they did not make any bitrate changes on their DTT except removing SD version of Channel U and okto channel.

The question is about your aunt - can she get used to 2 remotes?

Some folks can handle it, some can't.

For me, it was simple, the old TV stopped working, so I got a new one.

If you do not intend to get a new TV, just keep that TV remote away. Adjust the TV volume a bit higher, then in future just use the decoder remote to adjust volume. Turn on and off can just press button in front of TV, or just power off the socket.

Thanks for the info. IIRC similar to Astro, the 1080i25 that is used will be smoothed out on your TV to give an impression of 50FPS. But that only works IF the source is also 50FPS, which all sports broadcast should be. The source that RTM Sports uses is already re-converted to 25FPS, most likely due to them using the same source as their web stream. This is mightily noticeable in their MotoGP broadcast where it looks washed out compared to Fox Sports on Astro/HyppTV.

Ach, in a time where we are watching 1080p 6Mbps minimum on web, 3.5~4Mbps is certainly noticeable

It's 1080i50 - 50 interlaced fields which are 25 complete frames. AFAIK the TV will either smooth out to make 50FPS or merge two fields to make a 25FPS video depending on how the video is encoded.

With 8Mbps+ on Unifi TV and 15Mbps ~ 30Mbps on Blu-ray, even web streams are noticeably poorer quality.

where can i get the list of "exact coordinate" for the transmission towers?
i want to install outdoor antenna myself, but want to make sure it's pointed to tower from the right side of the house.

What is your area? Landed house or high rise buildings like conco, apartment, etc?
And why this antenna? It's not necessary to look nfor expensive ones.
The normal ones that you can buy online like from Lazada, Shopee, already good enough.

my wife insists on buying promo-priced noname tv with built-in digital tuner for parents, enough for them to keep up-to-date with current on-going.

but the shop don't have stock for proper outdoor antenna, told us most place ran out of stock as well, and told us to source it from elsewhere for them to install. so she bought this antenna from Senheng but now the 1st salesman denied that the shop is even providing outdoor installation service.

so it's up to me to make good on this investment before we move on to look again for the next antenna.
