The preferred modes for carrying out the invention are set forth in this section for the purpose of illustrating the concepts of the invention and not for the purpose of limiting the scope of the invention as defined by the claims.
Fig. 1 is a block diagram illustrating a data transmission system 100 according to an embodiment of the invention. As shown in fig. 1, the data transmission system 100 may include a transmitting device 110 and a receiving device 120. Note that the block diagram shown in fig. 1 is only for convenience of describing the embodiment of the present invention, but the present invention is not limited to fig. 1.
According to an embodiment of the present invention, the transmitting device 110 may be a desktop computer, a notebook computer, a tablet computer, and a smart phone, but the present invention is not limited thereto. According to the embodiment of the present invention, the receiving device 120 can also be a desktop computer, a notebook computer, a tablet computer, and a smart phone, but the invention is not limited thereto. In various applications, the transmitting device 110 may also be a receiving device, and the receiving device 120 may also be a transmitting device.
As shown in fig. 1, according to an embodiment of the present invention, the transmitting device 110 may include an encoding device 111 and a color developing device 112, but the present invention is not limited thereto. Other components may also be included in the transmitting device 110.
According to an embodiment of the present invention, the encoding device 111 encodes the data to be transmitted by the transmitting device 110 to the receiving device 120 into a color pattern. According to an embodiment of the present invention, the encoding apparatus may adopt a 2-bit (Binary), 8-bit (Octal), 10-bit (Decimal) or 16-bit (Hex) encoding method, but the present invention is not limited thereto. By the above encoding method, the encoding device 111 can encode data into a color pattern on the basis of a plurality of colors. Specifically, the 2-bit encoding scheme performs encoding with 2 colors. If the encoding device 111 adopts a 2-bit encoding method, the encoding device 111 converts the data to be transmitted from the transmitting device 110 to the receiving device 120 into a preset 2-bit code, and then converts the 2-bit code into a corresponding color code. The 8-bit encoding method is to encode with 8 colors. If the encoding device 111 adopts an 8-bit encoding method, the encoding device 111 converts the data to be transmitted from the transmitting device 110 to the receiving device 120 into a preset 8-bit code, and then converts the 8-bit code into a corresponding color code. The 10-bit encoding method is to encode 10 colors. If the encoding device 111 adopts a 10-bit encoding method, the encoding device 111 converts the data to be transmitted from the transmitting device 110 to the receiving device 120 into a preset 10-carry code, and then converts the 10-carry code into a corresponding color code. The 16-bit encoding method is to encode with 16 colors. If the encoding device 111 adopts a 16-bit encoding method, the encoding device 111 converts the data to be transmitted from the transmitting device 110 to the receiving device 120 into a preset 16-carry code, and then converts the 16-carry code into a corresponding color code. The following will describe tables 1 to 3 as examples.
TABLE 1
Table 1 shows the result of encoding characters (letters) A-Z by using a 2-bit encoding method according to an embodiment of the present invention, but the present invention is not limited thereto. As shown in table 1, the symbols a to Z are encoded in black and white in table 1, but the present invention is not limited thereto.
TABLE 2
Table 2 shows the results of encoding characters (numbers) 0-9 by using 2-bit encoding according to one embodiment of the present invention, but the present invention is not limited thereto. As shown in Table 2, although the present invention is not limited thereto, the symbols (numbers) 0-9 are encoded in black and white in Table 2. For example, if the data to be transmitted from the transmitting device 110 to the receiving device 120 is a Media Access Control (MAC) address 02: 00: 00: 00: 00: 00, the encoding device 111 encodes the MAC address into a color pattern according to the encoding method shown in Table 2 (as shown in Table 3 below). If the data to be transmitted from the transmitting device 110 to the receiving device 120 is a Media Access Control (MAC) address 02: 13: 45: 67: 8A: 0D, the encoding device 111 encodes the MAC address into a color pattern according to the encoding method shown in tables 1 and 2.
TABLE 3
| Character element | 8 carry code | Color coding |
| 0 | 0 | Black colour |
| 1 | 1 | Green |
| 2 | 2 | Yellow colour |
| 3 | 3 | Red wine |
| 4 | 4 | Blue (B) |
| 5 | 5 | White colour (Bai) |
| 6 | 6 | Pink |
| 7 | 7 | Light blue |
| 8 | 10 | Green and black |
TABLE 4
Note that the encoding methods shown in tables 1 to 3 are only used to illustrate the embodiments of the present invention, but the present invention is not limited thereto. The encoding device 111 can also use different colors or different encoding methods for encoding. For example, Table 4 shows the results of encoding words 0-8 using 8-bit encoding according to another embodiment of the present invention, but the invention is not limited thereto. As shown in Table 4, 8 colors are used to encode the characters 0-8, but the invention is not limited thereto.
In addition, the data to be transmitted from the transmitting device 110 to the receiving device 120 is not limited to the address data (MAC address). That is, in other embodiments of the present invention, the data to be transmitted by the transmitting device 110 to the receiving device 120 may be other types of data.
According to an embodiment of the present invention, if the data to be transmitted to the receiving device 120 by the transmitting device 110 is an address data, when the receiving device 120 obtains the address data, the receiving device 120 can establish a connection (for example, Wi-Fi, but the present invention is not limited thereto) with the transmitting device 110 according to the address data, and perform subsequent data transmission with the transmitting device 110 through the established connection.
According to another embodiment of the present invention, if the data to be transmitted to the receiving device 120 by the transmitting device 110 is other types of data, the receiving device 120 can also directly decode the color pattern by the data transmission method proposed in the embodiment of the present invention to obtain the data to be transmitted by the transmitting device 110.
According to an embodiment of the present invention, the encoding device 111 adds a start bit and an end bit to data to be transmitted to the receiving device 120 by the transmitting device 110 when encoding the data. The encoding device 111 also converts the start bit and the end bit into their corresponding color codes. Before the color pattern is displayed by the color display device 112, the color code corresponding to the start bit is displayed by the color display device 112. For example, if a 2-bit encoding method is taken as an example, the color encoding corresponding to the start bit can be "black", but the invention is not limited thereto. After the color pattern is displayed on the color display device 112, the color display device 112 displays the color code corresponding to the end bit. For example, if a 2-bit encoding method is taken as an example, the color encoding corresponding to the end bit may be "white, white", but the invention is not limited thereto.
According to an embodiment of the present invention, the encoding device 111 inserts a pause bit between characters (letters or numbers) of data when encoding the data to be transmitted from the transmitting device 110 to the receiving device 120. If the data to be transmitted by the transmitting device 110 to the receiving device 120 is a mac address 02: 13: 45: 67: 8A: 0D, the encoding device 111 inserts a pause bit between 0 and 2, a pause bit between 2 and 12, and so on. The encoding device 111 also converts the pause bits into their corresponding color codes. For example, if a 2-bit encoding method is taken as an example, the color encoding corresponding to the pause bit may be "white-white", but the invention is not limited thereto.
According to an embodiment of the present invention, after the encoding device 111 encodes the data to be transmitted from the transmitting device 110 to the receiving device 120 into a color pattern, the color-developing device 112 of the transmitting device 110 sequentially displays the color codes included in the color pattern according to the color pattern generated by the encoding device 111. According to an embodiment of the present invention, the color-displaying device 112 may be a display (e.g., a screen of a mobile phone). When the color display device 112 is a monitor, different colors are sequentially displayed on the monitor according to the color codes included in the color patterns. According to an embodiment of the present invention, the color display device 112 may be a Light-emitting diode (LED) device. When the color display device 112 is a led device, the led device sequentially activates leds of different colors according to the color codes included in the display color pattern.
Referring back to fig. 1, according to an embodiment of the present invention, the receiving device 120 may include an image capturing device 121 and a decoding device 122, but the present invention is not limited thereto. Other components may also be included in the receiver 120.
According to an embodiment of the present invention, the image capturing device 121 of the receiving device 120 captures the color pattern displayed by the color display device 112. Specifically, if the display device 112 is a monitor, the image capturing device 121 captures a frame displayed on the monitor to capture images of a plurality of frames (frames) (for example, 1 second to capture 30 frames of images, but the invention is not limited thereto). If the color display device 112 is a light emitting diode device, the image capturing device 121 captures the light emitting diodes of the light emitting diode device to capture a plurality of frames of images (e.g., 1 second to capture 30 frames of images).
According to an embodiment of the present invention, the decoding device 122 decodes the color pattern according to the color pattern acquired by the image acquiring device 121 to acquire the data to be transmitted by the transmitting device 110 to the receiving device 120. Specifically, the decoding device 122 uses the decoding method (e.g., 2-bit, 8-bit, 10-bit or 16-bit decoding method) corresponding to the encoding method (e.g., 2-bit, 8-bit, 10-bit or 16-bit encoding method) used by the encoding device 111 to identify the color displayed by the color-developing device 112 according to the plurality of frame images corresponding to the color pattern acquired by the acquiring device 121, so as to decode the color pattern back to the data to be transmitted to the receiving device 120 by the transmitting device 110.
According to an embodiment of the present invention, when the decoding device 122 decodes the color pattern, the decoding device 122 averages the pixel values of the plurality of frame images obtained when the image obtaining device 121 obtains the color pattern every n frames, where n is an integer greater than or equal to 2. Then, the decoding device 122 will identify the color displayed by the color-developing device 112 according to the averaged frame images, so as to decode the color pattern back to the data transmitted by the transmitting device 110 to the receiving device 120. For example, if the image capturing device 121 captures 30 frames of images and the decoding device 122 averages every 3 frames, the decoding device 122 averages the pixels of the images of the 1 st to 3 rd frames to generate the first frame average image. Then, the decoding device 122 averages the pixels of the images of the 2 nd to 4 th frames once to generate the second frame averaged image. Then, the decoding device 122 averages the pixels of the images of the 3 rd to 5 th frames once to generate the third frame average image. That is, the decoding device 122 averages each frame of image with the previous frame of image and the next frame of image. In this way, after the decoding device 122 performs the averaging operation on the pixels of all the images, the decoding device 122 will identify the color displayed by the color-developing device 112 according to all the averaged images, so as to decode the color pattern and transmit the color pattern to the data transmitted by the transmitting device 110 to the receiving device 120. In particular, the above examples are only for illustrating the embodiments of the present invention, but the present invention is not limited thereto.
According to an embodiment of the present invention, the decoding device 122 starts decoding the color pattern after recognizing the start bit, and stops decoding when recognizing the end bit.
According to an embodiment of the present invention, the plurality of receiving devices can respectively and simultaneously obtain the color patterns displayed by the color developing device 112 of the transmitting device 110, and decode the color patterns to obtain the data to be transmitted by the transmitting device 110.

As shown in fig. 2, in step S210, a transmitting device of the test system 100 encodes a data into a color pattern. In step S220, the color pattern is displayed on the transmission device. In step S230, a receiving device of the test system 100 obtains the color pattern. In step S240, the receiving device decodes the color pattern to obtain the data.

According to an embodiment of the present invention, the color-developing device may be a display. According to another embodiment of the present invention, the color-developing device may be a light-emitting diode device.
According to an embodiment of the present invention, the data transmission method further includes the step of obtaining the color pattern by an image obtaining device of the receiving device. According to an embodiment of the present invention, the data transmission method further includes decoding the color pattern obtained by the image obtaining device by a decoding device of the receiving device to obtain the data. According to an embodiment of the present invention, the data transmission method further includes the step of averaging every n frames of the images of the plurality of frames acquired by the image acquisition device when the image acquisition device acquires the color pattern by the decoding device, and then decoding the color pattern, wherein n is an integer greater than or equal to 2.
According to an embodiment of the present invention, in the data transmission method, if the data to be transmitted by the transmitting device is an address data, the data transmission method further includes establishing a connection with the transmitting device through the receiving device according to the address data when the receiving device obtains the address data.
According to the data transmission method provided by the embodiment of the invention, the transmitting device can encode the data to be transmitted into the color pattern.
