The copyright issue of the compilation works needed to be analyzed according to the specific situation. Generally speaking, the copyright of a compilation involved the copyright of the original work and the copyright of the compilation.
If a compilation was an adaptation of the original work, then the copyright of the compilation would usually belong to the original copyright owner. This was because compilation works were the combination of multiple independent works or content to form a new work. In this case, the copyright of the compilation should be regarded as a part of the copyright of the original work, so the copyright of the compilation should also belong to the copyright owner of the original work.
On the other hand, if a compilation was based on the inspiration or creativity of the original work, the copyright of the compilation would usually belong to the copyright owner. This is because compilation works are usually based on the original work and modified and combined to form a new work. In this case, the copyright of the compilation should be regarded as a derivative of the copyright of the original work. Therefore, the copyright owner of the compilation should have the right to use part of the copyright of the original work, including the right to adapt and compile.
If the copyrights of the compilation work belong to the original copyright owner, the composer may have to pay the copyright owner a fee. In addition, if the copyright of the compilation works belongs to the copyright owner of the compilation works, the person who adapted the compilation works only needs to pay the copyright owner of the original works the fee for the compilation works.
The copyright of the compilation works needed to be analyzed according to the specific situation and the distribution of rights between the copyright of the original works and the copyright of the compilation works.
