The Beijing Treaty on Audiovisual Performances (Beijing Treaty or BTAP) deals with the intellectual property rights of performers in audiovisual performances. Given the nature of the industry, a lot of actors in our favourite series and movies work on contractual agreements wherein they transfer all their rights to the producer of the audiovisual fixation of the performance for a lump sum amount of money without a claim for equity stakes or royalty rights for the otherwise use of the performance. The Beijing Treaty helps give these performers more rights to their work, which in turn boosts their personal revenues. This treaty makes an attempt to provide protection to the work of the performers/actors at par with the lyricists, music composers and producers. The treaty also considers the impact of digitization on the rights and makes required provisions accordingly.

P.S.: India is not a contracting state to the above-mentioned treaty. However, the Indian copyright law does provide for the moral and economic rights for the performers. [Sec 38, 38A, 38B and 39 of the Copyright Act of 1957.]
