Abstract
A video conferencing system is disclosed. The video conferencing system includes a transmitter and a receiver. When the transmitter is coupled to a port of an information processing apparatus, the transmitter communicates with the information processing apparatus to determine whether the port of the information processing apparatus has video output function. When the above determination result is no, the transmitter emits a wireless signal. The transmitter is coupled to a display apparatus and used to receive the wireless signal and provide a default warning message to the display apparatus.
Claims15
A video conferencing system, coupled between an information processing apparatus and a display apparatus, the video conferencing system comprising:
- a transmitter, when the transmitter is coupled to the information processing apparatus, the transmitter transmitting an extended display identification data (EDID) to the information processing apparatus, so that the information processing apparatus identifying the transmitter as a virtual display apparatus according to the EDID and providing an image signal to the transmitter, and the transmitter wirelessly transmitting the image signal;
- and
- a receiver, coupled to the display apparatus, configured to wirelessly receive the image signal transmitted by the transmitter and provide the image signal to the display apparatus;
- wherein the receiver receives a human interface device (HID) command transmitted by the display apparatus or a peripheral input apparatus through a data transmission channel;
- the receiver wirelessly transmits the HID command to the transmitter, and the transmitter transmits the HID command to the information processing apparatus through the data transmission channel.
A transmitter, applied to a video conferencing system, the video conferencing system further comprising a receiver, the transmitter comprising:
- an image receiving unit, when the transmitter is coupled to an information processing apparatus, the transmitter transmitting an extended display identification data (EDID) to the information processing apparatus, so that the information processing apparatus identifying the transmitter as a virtual display apparatus according to the EDID and providing an image signal with a first format to the image receiving unit;
- a first control unit, coupled to the image receiving unit and configured to convert the image signal with the first format into the image signal with a second format;
- and
- a first wireless transmitting unit, coupled to the first control unit and configured to wireless transmit the image signal with the second format to the receiver, and then the receiver providing the image signal with the second format to a display apparatus;
- wherein the receiver receives a human interface device (HID) command transmitted by the display apparatus or a peripheral input apparatus through a data transmission channel;
- the receiver wirelessly transmits the HID command to the transmitter, and the transmitter transmits the HID command to the information processing apparatus through the data transmission channel.
