Solution

Description

Benefit

Integration with a user interface (UI)

The solution provides the UI of online karaoke rooms, including the complete UI interaction process. You can call API operations of online karaoke rooms to update the UI. To use the solution, you must use ApsaraVideo services such as ApsaraVideo Real-time Communication (ARTC) SDK and interactive messaging SDK while adhering to the frontend and backend interaction protocols for the AppServer.

The solution allows you to customize the UI without the need to deeply understand the logic of the model layer. You can run the AUIKaraokeRoom component within a few minutes by modifying only a few lines of code. We recommend that you use this solution if your manpower or project period is limited.

Integration without a UI

The solution encapsulates the API operations of online karaoke rooms, including the operations to manage rooms, microphones, sound effects, audio mixers, music libraries, song requests, and the player component. The solution does not encapsulate the API operations to manage the UI.

You can use the solution to integrate online karaoke rooms in a more flexible manner without the need to deeply understand the logic of the model layer. The solution supports custom implementations. For example, after you integrate the ARTCKaraokeController component, you can customize its API implementations to work with your own instant messaging (IM) solution or existing server-side interaction protocols.
