Previously, the regulator required each network to have two high-definition channels and six standard-definition channels.
Natee Sukonrat, chairman of the NBTC's broadcasting committee, said it agreed to add three more options for the five licensed network operators to adjust their channel composition. These operators will provide services for public and commercial digital TV channels.
The first option is one HD and nine SD channels per network. The second option is two HD and six SD channels. Lastly, one network will provide three HD and three SD channels.
The licensed network operators can choose for themselves.
"The three options will make the network operators more flexible so they can effectively provide services," said Col Natee.
The NBTC required six network providers to provide networks for digital TV channels. The first five licensed network providers will provide service for public and commercial channels.
The last licence will be for community channels, to be issued next year once details of community-service channels are finished. Key factors used to license the last network include the switch-off analogue signal transmissions by network providers and their broadcasting towers covering 39 major areas nationwide.
Moreover, the NBTC plans to extend the one-year licences next year for non-frequency broadcasters (satellite and cable) for another two years.
In January, the regulator approved licences for 500 non-frequency broadcast channels. So far, 900 satellite and cable channels are licensed.
Those to receive the two-year licence extension will be screened on many areas including avoiding exaggerated advertising and illegal content.
"We will intensify the regulations and alter the licensing scheme based on consumer complaints next year," Col Natee said.
