The musical industry has developed types of licences in respect of music-related works:
Mechanical license permits a licensee to record, reproduce and distribute musical works in recording media such as records, cassette tapes, CD's, etc.
Synchronization and Videogram Licence
Synchronization license permits a licensee to bundle music together in timed relation with visual images or motion pictures to create a work combining the audio and the visual content. Programmes on TV or films may have part of their scenes supported with music as the background.
Public Performance Licence
Public performance licences permits the licensee to publicly perform the musical composition.
As the music-related works are frequently used in public performance by different people or organisations, this right is very often managed through collective agent. In Hong Kong, such collective agent is CASH. A licensee desiring to publicly perform a song would have to enter into a licence agreement with CASH. Such licensing would require payment of royalty.
New Media Licence
This is a developing area of licensing. The Copyright Ordinance has been built based upon conventional technology. The Internet has offered a new mode of distribution for multimedia productions and has posed as a challenge. Certain leading copyright agent such as America's RIAA has created the webcast licensing framework for 'broadcast' of music over the Internet.
The Copyright Ordinance does not provide a specie of audio-visual work as a type of copyright work. Rather, audio-visual work is classified as 'film'. Film means 'a recording on any medium from which a moving image may by any means be produced'. By the definition, a video clip, no matter how primitive or home-made it is, belongs to a film and is protected by copyright.
The sound-track accompanying a film is to be treated as part of the film for the purposes of the definition of film. The director of the film is the author and hence the first copyright owner of a film.
The licensing of a film is much simpler if the composition does not include other copyright works such as musical recordings. Caution must be taken in respect of a film which may orginate from the adaptation of a literary work such as a novel. Copyright clearance requires the authorisation of the copyright owner of the novel for the production of the fillm.
