Abstract: In a method for recording and playing multimedia audiovisual programs using a first television, the first television being is connected to a second television. The first television records a current multimedia audiovisual program being played on the first television in response to a recording command generated according to a user's operation, and sends the recorded multimedia audiovisual program to the second television according to an invoking command received from the second television.

Abstract: A remote controller generates control signals according to the speed of movement sensed by a three-axis accelerometer and the direction of movement sensed by a gyroscope and transmits the control signals to a remotely controlled device communicating with the remote controller when the remote controller is in a first work mode, generates control signals according to touch sensing signals from a touch pad and transmits the control signals to the remotely controlled device when the remote controller is in a second work mode, and further generates control signals according to variations in the capacitance of the capacitive type pressure transducer unit and transmits the control signals to the remotely controlled device when the remote controller is in a third work mode.

Abstract: A touch panel includes a first substrate, an electronic circuit board, a second substrate, and a number of touch-sensing members arranged on the electronic circuit board. Each of the touch-sensing members comprises a metal dome, an insulating layer covering the metal dome, and a sensing layer formed on the insulating layer. A number of contacting tabs are arranged on the electronic circuit board corresponding to each of the metal domes. The sensing layer generates a first signal in a touch mode when the touch panel is touched by a conductor. The contacting tab generates a second signal in a button mode when the second substrate is deformed when the second substrate is pressed, and the metal dome comes into contact with the contacting tab.

Abstract: A remote control system for controlling remotely a plurality of remote controllable appliances includes a first and second mobile terminal, at least one remote control apparatus, a server, and at least one remote control apparatus. The first mobile terminal transmits a first wireless signal in response to a remote controllable appliance selection and a function to be performed to the server. The server transmits a second wireless signal carrying an identification for identifying the selected remote controllable appliance and the selected function to the second mobile terminal. The second mobile terminal transmits a third wireless signal carrying an infrared remote control code correspondingly to the remote control apparatus, thereby the remote control apparatus transmitting an infrared remote control signal carrying the infrared remote control code to the selected remote controllable appliance to execute the selected function.
