TELEVISION stations will have to display warning notices before screening programmes which are not suitable for children, a government official revealed yesterday. According to a recent recommendation by the Television and Entertainment Licensing Authority (TELA), both ATV and TVB will have to alert parents before showing programmes which contain sex, violence or other scenes that are unfit for children. According to the present code of practice, stations are allowed to broadcast such programmes between 8.30 pm and 11.30 pm. But they can spontaneously display advisory or cautionary notices whenever they think it is necessary. Rose May Li, Principal Entertainment Standards Control Officer said: 'The new guidelines will make the display of these notices compulsory and define more clearly when and how to broadcast them. She added that warnings would also be required before adult programmes between 11.30 pm and 6 am. 'Audiences become cleverer. They are fighting for more [programme information] before they decide which programmes they should watch,' said Ms Li. The proposal is one of the recommendations made by TELA in the mid-term review on the television licences. Both the licences of ATV and TVB will expire in December 2000. The Broadcasting Authority last year finished its report on the three public hearings for the review. Although Ms Li refused to give further details about the proposal, she stressed the guidelines would specify the format and wordings of the notices and would be written into the code of practice. Currently, stations are advised to broadcast warning notices before screening some documentaries and sports programmes with scenes unfit for children during family viewing hours, from 4 pm to 8.30 pm.
