Detailed Description
The present invention will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present invention more apparent.
Based on the above object, a first aspect of the embodiments of the present invention proposes an embodiment of a data transmission method. Referring to fig. 1, a flow chart of an embodiment of a data transmission method provided by the present invention is applied to a receiving terminal, and includes:
step 101: receiving a connection code generation request;
step 102: transcoding the IP address of the receiving terminal according to a preset mapping relation according to the connection code generation request to obtain a connection code;
step 103: and establishing connection with the sending terminal by using the connection code.
As can be seen from the above embodiments, the quick connection of the transmitting terminal and the receiving terminal is achieved by transcoding the IP address. It should be noted that, the receiving terminal may be not only a device to be projected or transferred in a projection or transfer process, but also a device to be projected or transferred, which may be understood that the device waiting to be connected may be the receiving terminal. Note that the IP address is an IPv4 address, and is not limited by the type A, B, C, D, E.
In some optional embodiments, the data transmission method further includes:
establishing a mapping relation between digital characters 0-25 and alphabetic characters A-Z, so that the digital characters and the alphabetic characters are in one-to-one correspondence;
the transcoding the IP address of the receiving terminal according to the preset mapping relation comprises the following steps:
and converting the numerical character of the IP address into the alphabetic character according to the mapping relation.
Alternatively, the one-to-one correspondence may be sequentially corresponding to the order of 0-25 and a-Z, and the specific mapping relationship table is as follows:
TABLE 1 mapping relationship table between numeric characters and alphabetic characters
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 |
| A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
It should be noted that, in addition to the embodiment in which the correspondence is performed in the order of 0-25 and a-Z, the correspondence may be in reverse order or in disorder, such as the letter Z corresponding to the number 0, or the letter M corresponding to the number 0 and the random, or the uppercase letter a-Z may be the lowercase letter a-Z. However, it is to be appreciated that there cannot be duplication of correspondence between the numeric characters and the alphabetic characters.
In some alternative embodiments, the converting the numeric character of the IP address into the alphabetic character according to the mapping relationship includes:
dividing the IP address into four digital character segments, wherein each digital character segment comprises three digital characters;
and converting the adjacent first two digital characters in each digital character segment into corresponding first letter characters to obtain character segments formed by letters and numbers.
In some alternative embodiments, the IP address is converted to a concatenated code, the 12-digit numerical characters of the IP address are divided into four numerical character segments with dots as separators, and each numerical character segment is an integer from 0 to 255, and each numerical character segment includes 3-digit numerical characters. For example, an IP address of 192.168.254.253, the four digital characters representing the IP address are 192, 168, 254, and 253, respectively, with the three-digit digital characters in the first digital character segment being 1, 9, and 2, respectively. When the number of the digital characters in the digital character segment is less than three, 0 is added before the original digital character segment, and the original digital character segment is supplemented to three.
In some alternative embodiments, the first two adjacent digits in each digit segment are converted into the corresponding first alphabetic characters, resulting in a segment of alphabetic and numeric characters. For example, referring to fig. 6, take a first connection code 192.168.254.253 as an example one:
in this embodiment, referring to table 1, the first two digits in each digital character segment are a group, the last digit is a group, the letter corresponding to the digit 19 is T, and so on, to obtain a second connection code with only 8 digits, which is shortened by 4 digits compared with the original 12 digits. It should be noted that, in addition to the above embodiment of converting the first two adjacent digits in each digit segment into the corresponding first alphabetic character, the last digit in each digit segment may be converted into the second alphabetic character, and this conversion mode may also shorten the original 12-digit character into the 8-digit character, however, conventionally, it is considered that simply inputting letters is more convenient compared with mixing input digits and letters, and in the actual operation process, the corresponding transcoding mode may be selected according to the input habit of the connection code inputter. When the connection is established, the connection code formed by the conversion of the IP address is required to be manually input to realize the connection, so that the number of input characters is shortened, and the connection speed between devices in the screen transmission or screen throwing process can be improved.
It should be noted that, the connection code is a letter character converted by the IP address according to the mapping relationship. The IP address and the connection code can be mutually resolved, namely, the IP address can be converted into the connection code form by knowing the IP address, otherwise, the connection code can be converted into the IP address form by knowing the connection code. For example one, the IP address is a conventionally recognized IP address representation, i.e., a 12-digit numeric string of 192.168.254.253, and the connection code is tc.qi.ze.zd or t2.q8.z4.z3. In addition, the data transmission method provided by the embodiment converts the public-aware IP address expression form into a secret and public-unknown connection code form, protects the IP address of the equipment, and plays a role in protecting privacy.
Referring to fig. 2, in a second aspect of the present invention, another embodiment of a data transmission method is provided, which is applied to a transmitting terminal, and includes:
step 201: receiving a connection code generated by a receiving terminal;
step 202: restoring the connection code into an IP address corresponding to the receiving terminal according to a preset mapping relation;
step 203: and searching the receiving terminal according to the IP address and establishing connection with the receiving terminal. It should be noted that, the above-mentioned sending terminal may be not only a device to be projected or to be transferred in a projection or transfer process, but also a device to be projected or transferred, which may be understood that the device sending connection may be a sending terminal.
In some optional embodiments, the data transmission method further includes: establishing a mapping relation between digital characters 0-25 and alphabetic characters A-Z, so that the digital characters and the alphabetic characters are in one-to-one correspondence;
restoring the connection code into the IP address corresponding to the receiving terminal according to a preset mapping relation, wherein the method comprises the following steps:
and converting the alphabetic characters in the connection code into the numeric characters of the IP address according to the mapping relation to obtain the IP address corresponding to the receiving terminal.

dividing the connection code into four character segments, wherein each character segment comprises 1-bit alphabetic characters and 1-bit numerical characters;
and converting the alphabetic characters in each character segment into corresponding 2-bit digital characters to obtain a digital character segment formed by 3-bit digital.
The connection code is manually input to the sending terminal, and the sending terminal restores the connection code generated by the receiving terminal into the IP address of the sending terminal; when the method is applied to a system, the sending terminal finds the receiving terminal according to the restored IP address in the form of the IP address and is connected with the receiving terminal.
