there is an arrangement for LCN numbering by the government. Television stations themselves can apply for changes to their LCN numbers for several reasons, such as leaving the network broadcast system or another television network or other, but must meet the requirements of the Director General of Post and Telecommunication. Digital broadcast viewers (via television sets/STB), if they press the numbers on the remote control according to the LCN, they will go directly to the television station. The following are the virtual channel numbers of television networks in Indonesia (generally the same in various regions despite different frequencies, sometimes each regional or transmission station also has a different numbering configuration from the main network): In terrestrial digital television reception, because the reception position is close to other areas, sometimes there will be duplicated television stations resulting in two or more of the same TV station. Virtual channel numbering will assign the corresponding virtual channel number to TV stations whose signal is stronger, and weaker ones to be placed on channel entries of 800's and above. Likewise for TV stations that do not have virtual channels or the virtual channels have not been configured, they will be included in the 800s entry and sorted by signal strength from highest to lowest or by frequency. Grouping of virtual channel numbers in terrestrial TV Digital radio Digital radio also uses channels and subchannels in the DAB format. iBiquity's HD Radio uses HD1, HD2, ..., HD7 channels. HD1-3 are available in FM hybrid mode, while all seven HD channels are available in the pure digital mode. IBOC system (Digital Radio Mondiale) stations do not currently use any virtual channels because of the limited bandwidth available in analog sidebands.
