In the future - we may see a change on delivery method forĀ linear broadcast/terrestrial TV and radio - as the spectrum currently used by terrestrial TV (470-698MHz) is on risk on handed over to mobile operators for low band 5G/6G developments.
The broadcast method will be 5G Broadcast - which will potentially replace the existing DVB-T2 system in the future. The broadcast channels (TV/Radio) will be delivered over 5G networks - but using the method that is called eMBMS, or evolved Multimedia Broadcast Multicast Service. It could deliver live TV/radio services, VOD and emergency services in large amounts of people.
This means that large events (sports/national day celebrations .etc) can be delivered in the most efficient method to mobile devices/TV without the need of internet -
and the live sport experience will be similar to the way that what we are experiencing on terrestrial TV.
Any devices that support 5G will be able to receive the broadcast without any SIM cards or verifications. Coverage roll out will be done by using existing TV/radio masts and some mobile masts (to fill the gaps).
However, a migration to a newer platform will meant set top boxes for all the existing TVs (there will be newer TVs supportĀ the system by default) There will be simulcasts and switch off of the old DVB-T2 signal, similar to the way we are migrated from analogue to digital TV. (And by the time we migrated to this, we would probably be receiving UHD/8K signals via H.266 or even newer codecs).
Some countries in Europe are already experimenting broadcasts using 5G, in preparation in case if the spectrum is handed over to mobile operators during WRC-23.
As the FM radio spectrum is overcrowded in certain parts of the country (Klang Valley, Johor Bahru .etc), it is currently impossible for new entrants to launch any radio services, even if they are interested. DAB+ (used in Europe) may be impractical because everyone will have to buy new radios, rollout of the entire new network and generally mobile devices doesn't support DAB+ reception (rather than FM that is widely supported). 5G broadcast will meant easy, high quality radio reception even on mobile devices with some necessary technical changes (such as converting existing TV masts into 5G broadcast main mast).
With 5G broadcast, it will be impractical to set very low audio bitrates (unlike the case of DAB+ and the current DVB-T2 with very appealing audio rates of 32kbps/48kbps.)
The migration to 5G broadcast from DVB-T2 here would likely happen in 2030s or later (considering that Malaysia will adopt the transition later than Europe) so you can still use the current DVB-T2 set top box/TVs until then.
I've heard about this, but from my recollection, only Germany seems to have done testing. The UK (which we usually based/import our technology from) doesnt' seem to be doing any testing/adoption currently. I presume this is due to the lockdown slowing down everything there, as well as BREXIT.
It's likely Europe won't even be prepared yet for this even when 2030 comes, which means it will also take longer in this region.
For the UK, they are going the Broadband route instead of broadcasting.
Similar to RTM Click/Mana mana, free OTA TV's will be available for streaming, but instead of downloading an app over play store, it would be built in directly into Smart TVs sold in the UK
