Previous Channel:
This option is used to switch to the channel before the current channel.
In the TV remote control or TV application, users can quickly return to the last viewed channel by clicking the "Previous Channel" button.
In some programming interfaces, it may be used to fall back to a previously used data channel.
Random Channel:
This option is used to randomly select a channel to watch or connect.
In TV or streaming services, users may want to try different programs, so the function of randomly selecting channels is provided.
In some programming or testing scenarios, randomly selecting channels may be used to simulate or test data transmission conditions of different channels.
Next Channel:
This option is used to switch to the next channel after the current channel.
Similar to "Previous Channel", but in the opposite direction, it allows users to browse forward through different channels.
