How to Continue to Receive these Six Digital TV Programme Channels?
If you are Building Management Offices / Incorporated Owners (BMOs/IOs) or other Property Managers
BMOs / IOs or other property managers should engage contractors of their common antenna broadcast distribution (CABD) systems / in-building coaxial cable distribution systems (IBCCDS) to reconfigure the systems from 1 April to 30 November 2021 for receiving and distributing the TV signals transmitted on the new DTT frequencies. image 7

Consistent with the arrangements adopted in the past similar exercises, owners of CABD systems / IBCCDS would need to bear the relevant cost.

Depending on the design of individual CABD systems / IBCCDS, you may need to inform residents / users to rescan the digital TV programme channels on their TV sets / DTT receivers after the completion of the system reconfiguration.

If you are living in Private Residential Estates / Buildings / Housing Courts of Various Subsidized Home Ownership Schemes
Residents of private residential estates, buildings, housing courts of various subsidized home ownership schemes, etc. installed with common antenna broadcast distribution (CABD) systems / in-building coaxial cable distribution systems (IBCCDS) should check with your building management office on the progress of CABD system / IBCCDS reconfiguration. You should follow the instructions given by the building management office whether and when you would need to rescan the digital TV programme channels on your TV sets / DTT receivers.
If you are living in Public Housing Estates
The Housing Authority or the Housing Society will be responsible for the common antenna broadcast distribution (CABD) systems / in-building coaxial cable distribution systems (IBCCDS) reconfiguration work. You should check with your building management office on the progress of CABD system / IBCCDS reconfiguration. You should follow the instructions given by the building management office whether and when you would need to rescan the digital TV programme channels on your TV sets / DTT receivers.
If you are living in Village Houses / Bungalows / Old Tenement Buildings
Residents of village houses, bungalows, old tenement buildings, etc. are usually using self-provided TV antennae for TV reception. In that case, if you cannot receive any of the six digital TV programme channels on your TV set / DTT receiver on or after 1 December 2021, you will just need to rescan the digital TV programme channels.
