Abstract: A video conference system including a first transmitter device and a receiver device is provided. The first transmitter device transmits a first video data. The receiver device includes a receiver control unit configured to assign a first identification code to the first transmitter device. The receiver control unit combines the first video data and a first identification image corresponding to the first identification code as a first combined video data and the receiver control unit outputs the first combined video data to the display device. Through the present invention, the conference participants can quickly identify which presenter is providing the video signal source corresponding to a particular frame on the split screen, and can raise questions to the right person.

Abstract: A video conference system including a transmitter device, a first receiver device and a second receiver device is provided. The transmitter device includes a transmitter control unit, a first network interface and a first wireless transmission module. The first receiver device includes a second wireless transmission module, a first receiver input interface and a first receiver video circuit. The second receiver device includes a second network interface and a second receiver video circuit. The first receiver video circuit combines the first video data and the second video data as a first combined video data. The first receiver video circuit transmits the first combined video data to a first display device, and outputs the first combined video data to the transmitter device, which outputs the first combined video data to the second receiver device through the first network interface and the second network interface.

Abstract: A video conference system including a transmitter device and a receiver device is provided. The transmitter device includes a transmitter control unit, a transmitter input interface, a transmitter video circuit and a first wireless transmission module. The transmitter control unit is coupled to a video output port of an information system and receive a first video data from the video output port. The transmitter input interface receives a second video data from a first video source. The transmitter video circuit combines the first video data and the second video data as a combined video data. The first wireless transmission module transmits the combined video data to the receiver device. The receiver device, coupled to the display device, includes a second wireless transmission module, which receives the combined video data. The receiver device transmits the combined video data to the display device.

Abstract: A wireless pairing system includes a remote controller and at least one display device. The remote controller includes a first processing unit, an input unit and a first wireless communication unit. The input unit includes a broadcast request key and a plurality of input keys. The display device includes a second processing unit, a display unit and a second wireless communication unit. The display device has an identification code. When the broadcast request key is triggered, the first processing unit sends out a broadcast request signal through the first wireless communication unit. When the second processing unit receives the broadcast request signal through the second wireless communication unit, the second processing unit controls the display unit to display the identification code. When the input keys are operated to input the identification code of the display device, the remote controller and the display device are paired with each other.

Abstract: A display system, a remote control device, and a display method are provided. The display system includes the remote control device and a display device. The display method includes following steps. The remote control device generates a vibration signal of housing by sensing an acceleration of a movement of the housing in a space. The remote control device transmits the vibration signal of housing to the display device. The display device displays a display image. In the display image, the indication path is pointed to an intersection position. An indication pattern is displayed at the intersection position, wherein an appearance of the indication pattern changes according to a number of times that the vibration signal of housing is received.

Abstract: A system for power management electrically connected to a solar cell is provided. The system for power management includes a photo-sensor, a controller electrically connected to the photo-sensor, and a power manager. The photo-sensor detects an illumination (illuminance or irradiance) of an environment where the solar cell is located. A look-up table of illumination vs. maximum output power is built in the controller, wherein a corresponding maximum output power is determined by the controller according to the illumination detected by the photo-sensor. The power manager is electrically connected to the controller and the solar cell. The power manager controls the output current of the solar cell so as to equalize an output power of solar cell and the corresponding maximum output power. A method for power management is also provided.

Abstract: Provided is an operation method applicable to sender device having a screen and a currently opened file displayed on the screen. When the sender device identifies a user gesture matching a predefined send command, the sender device performing following steps: (1) setting the currently opened file as a to-be-sent file when the sender device knows a file name of the currently opened file; otherwise capturing a current screen display on the screen as the to-be-sent file when the sender device does not know the file name of the currently opened file; (2) sending a sending request to a receiver device; and (3) sending the to-be-sent file to the receiver device when the sender device receives a response from the receiver device.
