Indeed. Our neighbor country Thailand 3+1mb is 590baht around RM60. They had promotion now which is 3+1mb=4mb link

Their 10mb link is 1490Baht which is around RM10

The promo link: http://www.3bb.co.th/product/adsl/4mb.php

I going to apply the 3+1mb link for my house at Chiangmai soon.  brows.gif  brows.gif

well
you cannot directly compare the price with wat tm offer in the unifi

as you can see unifi is not only hsbb.. it comes with free call to nationwide and also free iptv with some internationals channels as well as a few hd channel
besides that, it also come with a few freebies such as, phone, modem router, set top box

so the extra amount you paid for tm unifi compared to thai 10mbps package.. could be the subscription for ipvt , free nationwide call.. nod.gif

That's true, I just wish that if TM is going to offer HD IPTV I wish they were serious about video quality.

I don't know why the quality is so bad.

8Mbps should be enough bandwidth to stream high quality HD video at 720p.

8Mbps = 1MB / s = 60MB / min = 3.6 GB / hour  or 7.2GB / 2 hours

a 2 hour 720p movie is the same size.

So why is unifi HD so bad?
I think it's because they are sending out a 1080px size signal and as a result they have to over compress the file.

I would much rather have a high quality 720px resolution than an over-compressed 1080px resolution.
If they want to send out 1080px signals their bandwidth should be about 12Mbps not 8 Mbps.
I'm sure domestically they can handle the demands on speed, so why did they decide to underpower the IPTV?

I think the way you calculate is not so appropriate
the 7.3GB for 2hours 720p HD movie usually has multichannel audio(5.1) which consume some amount of bandwidth

usually TV HD broadcast does not have sound surround.

what tm is trying to offer the HD channel should similar to what youtube is doing hmm.gif

It's full SD resolution, but they're either compressing the quality too much, or just have the wrong settings entirely on the encoder.

To my eyes it looks like a really high mp4 compression..... the colours are oversaturated, it looks like they've converted it to progressive format - because there is a shutter / strobing effect, and it's obvious they're blending the fields together because the picture looks soft (out of focus).
They are also having a lot of trouble with interlace flickering - this is flickering you see on horizontal lines / graphics.

At least there's no ghosting effect, so they got 1 thing right.

How they got both progressive artifacts and interlace artifacts at the same time is beyond my understanding.

you mean the HD channels have those effects? O_O
or normal non-hd channel like NTV7 8TV have this effects??

TM should'nt have to apply the cap thing. it was great at the first, but ppl will get bored downloading or have no more space on their hard drives.. and they will stop downloading eventually. and just download when new tv series or movies came out. so TM, u'll get your precious bandwidth back, no need to apply the download limit..  tongue.gif
