TV and radio channels will return to their own programming but must refrain from entertainment and overly emotional content for 30 days, it was announced on Friday.
The Television Pool of Thailand (TPT) said that after the live coverage of the procession of King Bhumibol on Friday afternoon, all channels would broadcast documentaries on the late King's work and interviews with people about the King until midnight, and then return to their own programming.
Government spokesman Sansern Kaewkamnerd said radio and television channels as well as online media were requested to present appropriate content to audiences for the time being, to boost public morale, reduce confusion and relieve concerns in society.
"The content of programmes to be broadcast will suit the national situation and the sentiment of the people," Lt-Gen Sansern said.
The broadcasting committee of the National Broadcasting and Telecommunications Commission stated that programmes should not include any element of entertainment, dancing, joy, violence, impoliteness or overly expressed emotion.
Programme hosts, announcers and guests must dress in black and white tones, mainly black, without a pattern, and be polite.
Presented information and news on the passing of the King must be approved by directly responsible organisations and refrain from elaboration, analysis and criticism. Broadcast pictures must be in mourning tones of colour.
This would apply for 30 days from Thursday, and also apply to imported programmes.
In addition, channels will immediately relay TPT live broadcasts of royal ceremonies.
