The lower part of the broadcast band in the range of 470 – 614 MHz will continue to be used for supporting broadcasting services. This will involve the migration of the Multiple Frequency Network channels currently shared by Television Broadcasts Limited and HK Television Entertainment Company Limited to Single Frequency Network (“SFN”) Channel 37 (598 – 606 MHz), as well as the migration of Radio Television Hong Kong’s SFN Channel 62 (798 – 806 MHz) to SFN Channel 27 (518 – 526 MHz). To avoid interruption to the viewing of DTT services by the general public, simulcasting the DTT signals at both the existing and new TV frequency channels will be implemented between April and November 2021. https://www.cedb.gov.hk/ccib/eng/paper/pdf/cp20200819_01_e.pdf
