  • Publication number: 20130082920
    Abstract: A content-driven apparatus for controlling electronic devices integrates all control command functions for at least one controlled electronic device. Content information transmitted from one of the controlled electronic devices is received by a communication module, and is passed to a processing element for parsing the content information, including types of the content information, desired command actions to be proceeded, controlled electronic devices required to cooperate, and how to operate for a user. The processing element decides a user interface and an operation method for the user after the parsing, and issues corresponding control messages to the controlled electronic devices required to cooperate after the user uses the operation method to select specific control commands.
