In the connection method of the display device in the embodiment of the present invention, after receiving the instruction to create the connection, the second display device 10 displays the connection code with less than or equal to six bits, so that when the first display device 11 is connected to the second display device 10, the user can perform the connection only by inputting the connection code with less than or equal to six bits into the first display device 11.
Fig. 4 is a second flowchart of a connection method applied to a second display device according to an embodiment of the present invention, as shown in fig. 4, the connection method of the embodiment includes: step 103, receiving an instruction for creating a connection; step 104, generating a connection code; and 105, displaying a connection code, wherein the connection code comprises letters and/or numbers, and the number of the connection code is less than or equal to six bits. Steps 103, 104 and 105 are described below.
Step 103, receiving an instruction for creating a connection.
Step 103 has already been described above, and will not be described here.
Step 104, generating a connection code.
In one embodiment, the second display device 10 generates a concatenated code, for example a six-bit concatenated code, which is converted into a character every 5 binary bits from the upper to the lower bits, so that the six-bit concatenated code comprises 30 binary bits.
In one embodiment, the IP address of the second display device 10 is detected first, and the generated connection code is different when the IP address of the second display device 10 is different in type. In the local area network, the ip used by the second display device 10 includes three types:
(1) class a addresses 16777216: from 10.0.0.0 to 10.255.255.255;
(2) 1048576 addresses of B type: from 172.16.0.0 to 172.31.255.255;
(3) 65536 addresses of class C: from 192.168.0.0 to 192.168.255.255.
How the second display device 10 generates the connection code for the class a address, the class B address, and the class C address, respectively, will be described below.
When the IP address of the second display device 10 is a class a address, the class a address is from 10.0.0.0 to 10.255.255.255, the second display device 10 generates a six-bit connection code, the connection code includes 30 binary bits, and the binary bits of the connection code sequentially represent the type, check bit, port and IP address information from high to low, as shown in the following table:
29 28 27 26 25 24 23 0
type (B) Check bit Port(s) IP address information
Where, Bit29-28 is a type, and the type may be the type of an IP address, for example, 00 is used to indicate a type a IP address.
Bit27-26 is a check Bit, which may be, for example, a digit formed by the other bits of the concatenated code except the check Bit, and the digit is obtained by taking the remainder of 4. For the connection code input by the user, the check bit is calculated and compared with the check bit stored in the connection code, and whether the user inputs errors or not can be detected to a certain extent.
Bit24-25 is a port, and stores a subscript of a port array, for example, if the port array is {6543, 7383, 10023, 34323}, 0 indicates 6543, 1 indicates 7383, 2 indicates 10023, 3 indicates 34323, the port array is not fixed, the connection code of this embodiment includes a plurality of ports, so that when one port is occupied, other ports can be selected, which is convenient for a user to use.
Bit24-25 is IP address information, in the local area network, the first 8 bits of the class a address are fixed and only the last 24 bits are changed, so the IP address information in this embodiment includes the last 24 bits (i.e. the lower 24 bits) of the IP address of the second display device, which can both save the IP address of the second display device 10 and shorten the length of the connection code.
When the IP address of the second display device 10 is a class B address, the class B address is from 172.16.0.0 to 172.31.255.255, the second display device 10 generates a six-bit connection code, the connection code includes 30 binary bits, and the binary bits of the connection code sequentially represent type, check bit, change bit, port and IP address information from high to low, as shown in the following table:
29 28 27 25 24 22 21 20 19 0
type (B) Check bit Change position Port(s) IP address information
Where, Bit29-28 is a type, and the type may be, for example, the type of an IP address, and 01 is used to indicate a class B IP address.
Bit27-25 is a check Bit, which may be, for example, a digit formed by the other bits of the concatenated code except the check Bit, and the digit is obtained by taking the remainder of 8. For the connection code input by the user, the check bit is calculated and compared with the check bit stored in the connection code, and whether the user inputs errors or not can be detected to a certain extent. The check bits are calculated after the variance bits are scattered.
Bit24-22 is a change Bit, the change Bit is randomly generated within the range of 0-7, in order to enable the change Bit to influence other parts, the change Bit is dispersed, the change Bit of 3 bits is replaced with any three other bits, such as Bit24 and Bit20 replacement, Bit23 and Bit10 replacement, and Bit22 and Bit0 replacement, so that only one character change of 6 concatenated codes is avoided.
Bit21-20 is a port, and stores a subscript of a port array, for example, if the port array is {6543, 7383, 10023, 34323}, 0 indicates 6543, 1 indicates 7383, 2 indicates 10023, 3 indicates 34323, the port array is not fixed, the connection code of this embodiment includes a plurality of ports, so that when one port is occupied, other ports can be selected, which is convenient for a user to use.
