As promised, Mediacorp have upgraded/modified their audio system. After the changes, there are 3 audio tracks on all their channels except CNA, transmitting in 96kbps HE-AAC Stereo (main audio, as used on CNA), 64kbps HE-AAC Stereo (second audio, for dual sound tracks) and also 256kbps AAC 5.1 (this was their main audio before the change). Video bitrates remain unchanged, as well as CNA, which remained at 2 audio tracks. I had include the video links before and after the change for all to download (for Channel 5), in both MKV and raw TS file.

Thanks AV 2018 & Shaun, I read Hong Kong TVB transmit at around 14 Mbps .... but that was quite some time ago .... not sure if they have lowered the bitrate .... interesting how Hong Kong can go so high, haha.

Seems like Korea and Japan have 1080i channels that might be 12Mbps video (AVC) + 192~448kbps audio (AAC-LC or AC3). Of course they have 4K channels too. |

When watching tv broadcast example like tv2, the picture received on my tv is in hd, but it gets freeze while watching, occurring from time to time...
I'm using the outdoor antenna installed near the roof, the signal received on my tv shows 100%, does it likely consider normal on the picture freezing? |

The same reason Singapore can - tiny coverage area, so no need for dozens of transmitters and the very expensive satellite links feeding the transmitters.For comparison the UK uses about 6 Mbps for a HD channel |

I wonder is there any other country in the world that uses equal or less than 4Mbps for HD channels on DTT?For comparison the UK uses about 6 Mbps for a HD channel Let's see which country is even worse than Malaysia, so that I can convince myself that Malaysia is not that horrible. Erm, it's still terrible, but not horrible. Btw anyone here able to receive Brunei DTT channels, especially those staying nearby Brunei borders? I know their channels aren't interesting to watch, but I know all of their channels is in HD. I wonder what bitrate they use for video and audio...  |

QUOTE(dayojah @ Dec 4 2019, 10:25 PM) The same reason Singapore can - tiny coverage area, so no need for dozens of transmitters and the very expensive satellite links feeding the transmitters. All of the transmitters in SG can be/are feed by fiber optics, considering their small size and they already have such infrastructure in place.For comparison the UK uses about 6 Mbps for a HD channel While in HK only 3 channels have high bitrate (TVB Jade 10M, RTHK TV 31 8M, Open TV 14M). First two channels is feed terrestrially while the third is feed via cable (signal could be tuned via normal DTT/DTMB tuner if connected to MATV socket). Half of TVB Jade spectrum is shared with ViuTV, while TVB also have a multiplex that is used solely for 4 HD channels. Open TV has 1 MUX (feed via Cable) that carries 1 Cantonese and 1 English channel. RTHK has 1 MUX for 2 of their own channel + relay of CCTV-1. RTHK MUX is often not carried on some MATV systems, despite being public broadcasting. (HK DTMB MUX has around 21-22Mbps per MUX) Viewers which tune via antenna can only watch TVB, ViuTV and RTHK channels only. Other channels (ViuTV, Other TVB channels .etc) have the usual/common HD bitrate (4-6Mbps), although ViuTV had transmitted in 9Mbps before the start of their English channel ViuTVsix. Before ATV's closure, they had transmit their sole HD channel in 13-14 Mbps. This post has been edited by shaun_kok: Dec 5 2019, 12:35 AM |

Wah, seriously that high? While in HK only 3 channels have high bitrate (TVB Jade 10M, RTHK TV 31 8M, Open TV 14M). First two channels is feed via microwave while the third is feed via cable (signal could be tuned via normal DTT/DTMB tuner if connected to MATV). Half of TVB Jade spectrum is shared with ViuTV, while TVB also have a multiplex that is used solely for 4 HD channels. (HK DTMB MUX has around 21-22Mbps per MUX) Other channels (ViuTV, Other TVB channels) have the usual/common bitrate (4-6Mbps). Before ATV's closure, they had transmit their sole HD channel in 13-14 Mbps.  They use 64QAM or 256QAM? You have any idea how many channels/mux they use to cover nationwide? They can use bitrate that high because the mux are owned by them, and is not single operator like Malaysia, right? And how come they can use so many mux? Because they got money?  |
