Abstract: A remote control controls a karaoke device to select songs. The remote control stores a controller identifier, obtains a user unique code and control instructions input by a song selector, and combines the controller identifier, the user unique code, and each of the control instructions into a controlling message. The remote control transmits the controlling messages to the karaoke device to enable the karaoke device to collectively display the songs selected by the song selector and the user unique code corresponding to the song selector.

Abstract: A remote control system for a multi-screen display of an array of sub-displays tiled together contiguously includes a remote controller and a number of control boxes each of which is installed on a corresponding sub-display. The remote control is configured for receiving user input governing selection and control of the sub-displays, generating a control signal based upon the selection and the control of the sub-displays, and transmitting the control signal. Each control box is configured for receiving the control signal, identifying if the control signal is passed and transferred to a controller of corresponding sub-displays upon the selection of the sub-displays.
