Wah, seriously that high?
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?
HK uses a vastly different terrestrial system (Chinese DTMB) to ours (DVB-T2) and the nett bitrate for HK DTMB is around 21-22Mbps. In HK there are 4 MUX, which all of them are bulit and then owned by the broadcasters, so the broadcasters have absolute control (unlike in Thailand, Malaysia and similar with Singapore, Taiwan, Japan, Korea) on how much bitrate they want to use on each channel. HK only have 12 terrestrial TV channels, so they can use higher bitrates for great picture quality. 3 MUX are transmitting over the air while the fourth is transmitting solely via MATV/Cable systems. Based on the information of HK OFCA, the broadcasters uses more than 30 transmitters to cover city wide, given the hilly terrain in HK. TVB have 1 standalone MUX for 4 channels + 0.5MUX (1 Channel) which is shared by ViuTV (2 channels). RTHK (PSB) have 1 standalone MUX for 2+1 channels, but this MUX is left out by some older MATV system as only a few watches RTHK TV channels due to upgrading MATV systems costs a lot of money. while HK Open TV has another standalone MUX for 2 channels, transmitting via MATV/Cable only. Before the end of ATV broadcasts, ATV had owned 1 MUX + 0.5MUX shared with TVB too.They use 64QAM or 256QAM?
