SCHOOL lessons in copyright have been proposed in an effort to stem the illegal playing of music in restaurants and boutiques. CASH is producing an educational video that it wants shown to all secondary students. The proposal comes nine months after CASH demanded schools pay fees in return for the right to play music at functions such as open days and celebrations. CASH members fear students are unaware of copyrights that require payment in return for music being played outside their homes. 'This is a big problem,' said CASH general manager Leslie Ching Pui-wai. The video will outline the law involved and help youngsters who are planning to go into businesses involving music. The society hopes the Education Department and Trade and Industry Branch will share the cost. Educators were mostly unaware of copyright and the initiative would combine with licensing fees to inform, said Mr Ching. In January CASH called for licensing of schools that play music at functions, but this prompted an appeal for the fee to be waived for schools. The $1,300-a-year fee is incurred only when music is played at functions involving the public. More than half of Hong Kong's 1,000 schools have paid, according to CASH. Association of Heads of Secondary Schools honorary secretary Lisu Chow said last night that students should be made aware of their copyright responsibilities but there were more pressing issues to be taught such as corruption.
