A more thorough explanation:

Definition: Communication right is the power given to a copyright owner to allow or prevent their work from being shared with the public through interactive on-demand systems like the Internet. This right is included in the WIPO Copyright Treaty and the European Commission's Directive on the Information Society.

Example: A musician who owns the copyright to their song has the communication right to decide whether or not their song can be streamed on a music platform like Spotify. They can choose to allow it to be streamed or prohibit it from being shared with the public.

Explanation: The communication right gives the copyright owner control over how their work is shared with the public. In the example, the musician has the power to decide whether or not their song can be streamed on a music platform. This means that they can choose to earn money from the streams or keep their work private.
