Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.
In view of the above object, a first aspect of the embodiments of the present invention provides an embodiment of a data transmission method. Referring to fig. 1, a schematic flow chart of an embodiment of a data transmission method provided in the present invention is applied to a receiving terminal, and includes:
step 101: receiving a connection code generation request;
step 102: according to the connection code generation request, transcoding the IP address of the receiving terminal according to a preset mapping relation 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 fast connection between the sending terminal and the receiving terminal is realized by transcoding the IP address. It should be noted that the receiving terminal may be not only a device to be projected or transmitted during a screen projection or transmission process, but also a device to be projected or transmitted, and it can be understood that a device to be connected may be a receiving terminal. It should be noted 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 numeric characters 0-25 and alphabetic characters A-Z, so that the numeric characters correspond to the alphabetic characters one by one;
the transcoding the IP address of the receiving terminal according to the preset mapping relation comprises the following steps:
and converting the numeric characters of the IP address into the alphabetic characters according to the mapping relation.
Optionally, the one-to-one correspondence may sequentially correspond to each other according to the order of 0 to 25 and a to 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 | 1 0 | 1 1 | 12 | 1 3 | 1 4 | 1 5 | 1 6 | 17 | 1 8 | 1 9 | 2 0 | 21 | 2 2 | 2 3 | 2 4 | 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 where the one-to-one correspondence is performed according to the order of 0-25 and a-Z, the correspondence may be reversed or disordered, such as the number 0 corresponding to the letter Z, or the number 0 corresponding to the letter M randomly, or the capital letters a-Z may be lowercase letters a-Z. However, it is to be understood that there cannot be duplications in the correspondence between the numeric characters and the alphabetic characters.
In some optional embodiments, the converting the numeric characters of the IP address into the alphabetical characters according to the mapping relationship includes:
dividing the IP address into four numeric character segments, wherein each numeric character segment comprises three-digit numeric characters;
and converting the adjacent first two digital characters in each digital character segment into corresponding first alphabetic characters to obtain a character segment consisting of letters and numbers.
In some optional embodiments, the IP address is converted into a connection code, the 12-digit numeric character of the IP address is divided into four numeric character segments by using dots as separators, each numeric character segment is an integer of 0 to 255, and each numeric character segment comprises a 3-digit numeric character. For example, if an IP address is 192.168.254.253, the four numeric character segments representing the IP address are 192, 168, 254, and 253, respectively, where the three-digit numeric character in the first numeric character segment is 1, 9, and 2, respectively. It should be noted that, when the number of the numeric characters in the numeric character segment is not enough to three bits, 0 is added before the original numeric character segment, and the original numeric character segment is supplemented with three bits.
In some optional embodiments, the adjacent first two digits of the numeric characters in each of the numeric character segments are converted into corresponding first alphabetic characters, so as to obtain a character segment composed of letters and numbers. For example, referring to fig. 6, taking the first connection code 192.168.254.253 as an example one:
in this embodiment, referring to table 1, the first two digits of the numeric character field of each segment are a group, the last digit of the numeric character field is a group, the alphabetic character corresponding to the numeric character 19 is T, and so on, to obtain a second concatenated code having only 8 digits of characters, which shortens the 4 digits of characters compared with the original 12 digits of characters. It should be noted that, in addition to the above-mentioned implementation of converting the first two adjacent digits in each digital character segment into corresponding first alphabetic characters, the last digit in each digital character segment may also be converted into a second alphabetic character, and this conversion manner may also shorten the original 12-digit character to an 8-digit character, but, conventionally, it is considered that it is more convenient to simply input letters than to mix input digits and letters, and a corresponding transcoding manner may be selected according to the input habit of a connection code inputter in the actual operation process. Because the connection code formed by IP address conversion needs to be manually input to realize connection when the connection is established, the connection speed between the devices in the screen transmission or screen projection process can be improved by shortening the number of input characters.
It should be noted that the connection code is an alphabetic character converted from the IP address according to the mapping relationship. Mutual analysis can be realized between the IP address and the connection code, namely the known IP address can be converted into the connection code form, otherwise, the known connection code can be converted into the IP address form. For example one, the IP address is a conventionally recognized representation of the IP address, i.e., a 12-digit numeric string of 192.168.254.253, with the concatenated code being tc.qi.ze.zd or t 2.q8.z4.z3. In addition, the data transmission method provided by this embodiment converts the expression form of the IP address recognized by the general public into a more secret and unknown connection code form, protects the IP address of the device, and plays a role in protecting privacy.
Referring to fig. 2, a second aspect of the present invention provides another embodiment of a data transmission method applied to a sending terminal, including:
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 sending terminal may be not only a device to be projected or transmitted during a screen projection or transmission process, but also a device to be projected or transmitted, and it can be understood that both devices sending a connection may be sending terminals.
In some optional embodiments, the data transmission method further includes: establishing a mapping relation between numeric characters 0-25 and alphabetic characters A-Z, so that the numeric characters correspond to the alphabetic characters one by one;
restoring the connection code to the IP address corresponding to the receiving terminal according to a preset mapping relationship, including:
and converting the alphabetic characters in the connection codes into the numeric characters of the IP address according to the mapping relation to obtain the IP address corresponding to the receiving terminal.
Optionally, converting the alphabetic character in the connection code into the numeric character of the IP address according to the mapping relationship, including:
dividing the concatenated code into four character fields, wherein each character field comprises 1-bit alphabetic characters and 1-bit numeric characters;
and converting the alphabetic characters in each character segment into corresponding 2-bit digital characters to obtain a digital character segment consisting of 3-bit digits.
It should be noted that, the connection code is manually input to the sending terminal, and the sending terminal restores the connection code generated by the receiving terminal to its own IP address; when the method is applied to a system, the method is in an IP address form, and the sending terminal finds the receiving terminal according to the restored IP address and is connected with the receiving terminal.
