Abstract
A screen frame transmission system includes a receiving device and a transmitting device. The receiving device includes a display unit or an external display device for displaying a 2D bar code containing connection information. The transmitting device includes an image capturing unit for capturing an image of the 2D bar code. The transmitting device decodes the 2D bar code to obtain the connection information and establishes a communication connection with the receiving device therewith to transmit a screen frame, thereby simplifying operations of a user.
Claims26
A screen frame transmission system comprising:
- a receiving device comprising:
- a display unit, or a video port for electrically connecting with an external display device, wherein the display unit or the display device is for displaying a 2D bar code comprising connection information;
- a first communication interface for receiving a screen frame;
- and
- a first processing unit electrically connected with the first communication interface, and the display unit or the video port, for generating the 2D bar code and decoding the screen frame to be output by the display unit or the display device;
- and
- a transmitting device comprising:
- an image capturing unit for capturing the 2D bar code output from the display unit or the display device;
- a second communication interface for transmitting the screen frame;
- and
- a second processing unit electrically connected with the image capturing unit and the second communication interface, for decoding the 2D bar code to obtain the connection information, and establishing a communication connection with the receiving device with the connection information to transmit the screen frame.
A transmitting device working with a receiving device to form a screen frame transmission system, the receiving device displaying a 2D bar code comprising connection information and a screen frame transmitted by the transmitting device, the transmitting device comprising:
- an image capturing unit for capturing the 2D bar code;
- a communication interface for transmitting the screen frame to the receiving device;
- and
- a processing unit electrically connected with the image capturing unit and the communication interface, for decoding the 2D bar code to obtain the connection information, and establishing a communication connection with the receiving device with the connection information to transmit the screen frame.
A receiving device working with a transmitting device to form a screen frame transmission system, the transmitting device capturing and decoding a 2D bar code to obtain connection information, and establishing a connection with the receiving device with the connection information to transmit a screen frame, the receiving device comprising:
- a display unit, or a video port for electrically connecting with an external display device, wherein the display unit or the display device is for displaying a 2D bar code comprising the connection information;
- a communication interface for receiving the screen frame;
- and
- a processing unit electrically connected with the communication interface, and the display unit or the video port, for generating the 2D bar code and decoding the screen frame to be output by the display unit or the display device.
A computer readable media with a recorded computer program to be loaded by a transmitting device to execute a method of transmitting a screen frame to a receiving device comprising:
- capturing a 2D bar code displayed by the receiving device with an image capturing unit, the 2D bar code comprising connection information;
- decoding the 2D bar code to obtain the connection information;
- establishing a communication connection with the receiving device with the connection information;
- and
- capturing and transmitting the screen frame.
A computer readable media with a recorded computer program to be loaded by a receiving device to execute a method of receiving a screen frame from a transmitting device comprising:
- determining connection information;
- converting the connection information into a 2D bar code;
- displaying the 2D bar code with a display unit or an external display device to allow the transmitting device to capture the 2D bar code;
- and
- waiting for the screen frame transmitted by the transmitting device for output.
