This is one of the reason why MYTV first recommended 6Mbps for HDTV transmission although it is definitely not enough for good quality picture. It seems that MYTV will transmit HDTV quality pictures on around 4Mbps only due to TV operators complaining for high fees, which make heavy pixelation/breakup for complex pictures. Alternatively, HEVC codec could be used on similar bitrate with better quality pictures but the current generation of TV and set top boxes could not decode the picture.

Oh yes, if you downloaded the sample I recorded, at the scene where the kid plays with fireworks, you can see the pixelation. puke.gif

Give up on HEVC, if our dear broadcasters and mytv already have enough complaint with price and deployment even with H264, there is no way for HEVC to take root.

1 ) Normal UHF antenna will not need amplifier if one live near the transmitter and have clear line of sight. Plug and play.
2 ) The rotating UHF antenna where amplifer is built-in together with the motor. (This one normally uses power adapter 12V)
3 ) An UHF antenna with amplifer built-in at the box right in the antenna (Normally 5V 500mA supplied by decoder directly to the antenna via the Belling-Lee connector or F connector)
4 ) An UHF antenna without without any amplifier. In this case, one would purchase a USB powered amplifer to connect the antenna and tv. See below.

Thanks for the info, very informative.

I live about 40-50km from the transmitter. Using antenna without amplifier/booster I'm getting very grainy picture for analog transmission. With DVB-T2 decoder I'm not getting any channel at all. Does it need strong signal in order to detect the digital transmission?

It could be possible to use HEVC if the DTT transmission started much later. HEVC codec at that time is still on its early development stage and there were not even one receiver who has such chipset. As a result, they settled down on H.264 Some viewers tend to keep their existing decoders and TV as long as they could work. Some of them even want to wait for free decoders although one could easily get the official MYTV branded ones for RM 187 or those unbranded DVB-T2 decoders like K2 for around RM60-100! Because of this, it is no longer possible/feasible to use HEVC codec as it will render all existing DVB-T2 TVs and set top boxes useless.

Just like the case in Australia (when they start HDTV back on 2001), the best codec available at that time was MPEG-2 and broadcasters there also simulcast both SD and HD MPEG-2 channels in the same multiplex (Each TV station there gets 1X 7MHz multiplex with total bitrate of 23Mbps). Problems start to arise circa 2009-2010 when the broadcasters start multichannel operations as per government requirements. The main channels are also required to broadcast in MPEG-2 SDTV only, so as to take care viewers who purchase decoders back to year 2001 which only supports MPEG-2 SD. As a result, they lost not only primary channels in HD format which it used to have under old agreement, but had to suffer to HD secondary channels which these channels often broadcast aged content (sometimes back in the 50s!) + poor TV quality across all channels. When they restart HD broadcasts on 2015 using H.264 format, some viewers (especially those who are still using older decoders) are complaining to the television station why they cannot receive the HD version of said TV channel, in most cases just because they are using older equipment. When the main channel starts broadcast HDTV on H.264, the secondary channel which broadcast in MPEG-2 HD has to downgraded to MPEG-2 SD to accomdate it. In addition, viewers had to suffer low bitrate HDTV channels, as they still need to broadcast all the existing channels on MPEG-2 SD plus the HD simulcast main channel on H.264 in a single multiplex.

I am using samsung MU6300 UHD TV which has DVB-T2.
However during night time when i tried to see news i have frequent pixel jerk(not sure it is a correct term) and lose of sound which is very frustrating.
Is it my DVB-T2 receiver is not strong enough?
What can be done to overcome that?
Note:Oh, i live in an apartment.

Check the signal strength and signal quality. Esepcially signal quality, you need to have a decent SQ of at least 60% and above in order to have a more stable video image. You just need to adjust the location and orientation of your antenna for better SQ.

RTM HD is showing a repeat World Cup match. Image breakup can sometimes be noticed when there is a fast movement. Meanwhile, Astro Arena HD has a sharper image.

You probably live at fringe area if you mention grainy image for analog, consider to get a UHF amplifier.

CEEHHHHHH, and I thought it is only me who encounters that weird image breakup at RTM HD repeat match. bangwall.gif
Max bandwidth 4700 is being used throughout the match, there is no fluctuation.

EDIT:
Here a sample direct capture of RTM HD world cup match repeat today. Full of image breakdown

Link will expire after 30 days.

Wasted my time checking with 3 antennas and 2 amplifiers only to discover TV3 HD is running fine except RTM HD channel with image breakup. doh.gif

I did do a signal quality check, it is 9x% and randomly drop(not often tho), but signal quality is pretty low which is lower than 40% and sometimes 0%.
Antenna is at the roof top which is not accessible to us. I did highlight to the management, but it seems they just say to get njoi.
Is it recommended to get my own antenna and just fix it outside my window?

Your condo master antenna supports analog TV channels but not digital TV channels. If your location is not too far away from the nearest transmitter, you may try an indoor antenna. Adjust the location and orientation of your indoor antenna until getting signal quality of above 60%.

RTM HD is free..
And the world cup match is sponsored..
So we cannot demand much.. I'm actually surprise RTM gave HD eventho its quality sucks.. Didn't expected them to have HD this year laugh.gif

As for sharper image quality from Astro Arena HD.. Well they uses like 8Mbps compared with RTM...

That wall socket provided are not for digital signal. As someone suggested, if you are not far from tower why not get an indoor antenna.

Here the sample of "HD" repeat broadcast of uruguay vs egypt by RTM HD.

https://ufile.io/ys4m8
Ignore the greenish 2 seconds in front of the sample. The I-Frame is missing from the capture

Seem like image breakdown kinda fixed, but the amount of pixelation.....sigh...
