1. A conference system with low standby power consumption comprising:
a transmitter comprising:
a battery configured to provide power;
at least one link port configured to access data; and
a processor coupled to the battery and the at least one link port;
an image data source configured to transmit image data to the transmitter;
a receiver linked to the transmitter and configured to receive the image data; and
a display device linked to the receiver and configured to display the image data;
wherein the processor detects a link state between the image data source and the transmitter through the at least one link port, when the transmitter and the image data source are electrically coupled, the processor ceases to use the battery of the transmitter and controls the image data source for providing power to the transmitter, when the transmitter and the image data source are separated, the processor uses the battery of the transmitter for driving firmware of the transmitter, the link state comprises a power channel link state or a media transmitted data channel link state, after the image data source establishes a link to the transmitter through the at least one link port, the image data is transmitted from the image data source to the receiver through the transmitter, the receiver controls the display device for displaying the image data.
