Abstract: An intelligent interactive TV remote-control system includes: a server, a TV device, a set-top box device, and an intelligent interactive remote-control device. The server is used for storing multimedia data and providing usage authentication service. The TV device is provided for playing multimedia data. The set-top box device is connected to the server and the TV device for downloading multimedia data from the server and outputting the same to the TV device for display. The intelligent interactive remote-control device is started for being connected to the server to perform usage authentication service thereby matching with the set-top-box device. When matching is successful, the intelligent interactive remote-control device is connected to the set-top box device and an interactive remote-control interface is generated corresponding to a playing window outputted from the set-top box device and displayed on the TV device for remotely controlling the set-top box device.

Abstract: A connector assembly includes a female-base and a male-base. The female-base includes a first metal element and a first sleeve element. When in use, the female-base and the male-base are engaged with each other such that the second sleeve element is disposed in interior of the first sleeve element, and that the first metal element contacts the second metal element, so that an electric connection is established for conveyance of power, and of video or audio signal. Thereby, users may use the connector assembly to eliminate the use of extension cords or signal cables, so that risks and worries about connecting too many extension cords may be released. In addition, a great number of electric cords and signal cables behind electronic appliances can be reduced, and arrangement of cords is simplified, let alone a neat and tidy overall appearance of the electronic appliances can be obtained.

Abstract: A digital TV set-top box includes a casing, a fixing frame, an adapter board, a hard disk drive, and a sliding frame. The casing is provided with an opening, and the fixing frame is arranged with the hard disk drive. Since the sliding frame is smaller than the opening of the casing, the sliding frame can pass through the opening and be slidably arranged between two chutes of the fixing frame, and a connecting head of the hard disk drive can be correspondingly plugged into the adapter board so as to establish an electrical connection. As such, the present invention provides a TV set-top box that the hard disk drive can be assembled therewith or disassembled therefrom easily, so that the hard disk drive of the digital TV set-top box can be maintained or upgraded without the need of removing the whole upper casing of the set-top box.
