To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present application provides a screen projection processing method, optionally, the method is applied to an electronic device, where the electronic device may be a screen projection receiving end, and the screen projection receiving end performs screen projection interaction with at least two screen projection transmitting ends, as a first example, referring to fig. 2, fig. 2 shows an application scenario of the embodiment of the present application, where a device indicated by T is a screen projection receiving end; the P1 to P4 are screen-casting sending terminals respectively, and the content of the display interface of at least one screen-casting sending terminal in the screen-casting interaction process, namely P1 to P4, is cast to the display interface of a screen-casting receiving terminal; Q1-Q3 are external input devices of the screen projection receiving end, such as an external keyboard, a wired mouse, a wireless mouse, a remote controller and the like; furthermore, the input device may also be a built-in device of T, such as a touch screen or the like.
The method may comprise the steps of:
The first input can be from an external input device, such as the external input devices Q1 to Q3 in fig. 2, to input a command to the screen projection receiving end; the first input may also be applied to a display interface of the screen projection receiving end, for example, a touch input of a user on the display interface.
And after receiving the first input, the screen-casting receiving end acquires an event code corresponding to the first input and a target screen-casting sending end corresponding to the first input. The event code is the event code corresponding to the first input, and the event code is in a code form recognized by the screen-casting receiving end. Optionally, an embodiment of the present application provides a screen-projection reverse control method, that is, a screen-projection receiving end is used to control a screen-projection sending end, and a target screen-projection sending end is used to project a controlled device in a screen-projection reverse control scene. Referring to fig. 2, for example, if a user touches a screen projection receiving terminal, the screen projection receiving terminal transmits the touch operation to the screen projection transmitting terminal.
The target screen projection sending end is the screen projection sending end corresponding to the display area acted by the first input at the screen projection receiving end; as shown in fig. 2 from T1 to T4, for example, the display area of the screen projection receiving end is allocated to each screen projection transmitting end during the screen projection process, and the corresponding screen projection content is displayed in each display area. On the screen projection receiving end side, a user can select a controlled screen projection sending end by selecting different display areas. For example, if the user needs to operate P3, the user can input an operation or command in the display area T3 corresponding to P3 to implement reverse control P3.
And step 102, converting the event code into an initial key value corresponding to the target screen-casting sending end.
For example, according to a preset mapping relationship, the event code is mapped to obtain an input event corresponding to the first input, and an initial key value corresponding to the target screen-casting sending end side.
Different screen-casting sending ends may adopt different data protocols or data formats, and in order to enable the target screen-casting sending end to respond to the first input, the event code needs to be converted into a target key value which can be identified by the target screen-casting sending end.
As a second example, a User Input Back Channel (UIBC) protocol is adopted at a screen projection receiving end, and a target screen projection transmitting end is an android system as an example; the UIBC protocol adopts ASCII codes, and event codes at a screen projection receiving end need to be converted into key values which can be identified according to a system; for example, the following conversion relationship conversion is adopted:
uint8_t keyHash[84]＝{
00，00，00，00，00，//0～4；
00，00，48，49，50，//5～9；
51，52，53，54，55，//10～14；
56，57，42，35，00，//15～19；
00，00，00，00，00，//20～24；
00，00，00，00，65，//25～29；
66，67，68，69，70，//30～34；
71，72，73，74，75，//35～39；
76，77，78，79，80，//40～44；
81，82，83，84，85，//45～49；
86，87，88，89，90，//50～54；
44，46，18，18，10，//55～59；
10，9，32，00，00，//60～64；
00，13，8，96，45，//65～69；
61，91，93，92，59，//70～74；
39，47，64，00，00，//75～79；
00，43//80～81}；
uint8_t keyHash_Num[20]＝{
48，49，50，51，52，//144～148；
53，54，55，56，57，//149～153；
47，42，45，43，46，//154～158；
44，13，61，40，41//159～163}。
if the event code is a key, the key is equal to or larger than 144, and the key is equal to or smaller than 163, the key is an input received by a small keyboard of the screen projection receiving end, and at this time, the target key value key' is key hash _ Num [ key-144], that is, the key value of the small keyboard minus 144 is converted into the target key value of the android system.
Otherwise, the target key value key' is keyHash [ key ].
By adopting the conversion relation, the event code at the screen projection receiving end can be converted into a target key value which can be identified by the android system.
Sending a target key value to a target screen-throwing sending end, enabling the target screen-throwing sending end to respond to the target key value, and realizing reverse control on the screen-throwing sending end side at a screen-throwing receiving end side; therefore, in the screen projection interaction process, a user can directly operate at a screen projection receiving end, such as editing characters, browsing webpages and the like, operation at a screen projection sending end is not needed, and the degree of dependence of the screen projection interaction process on the screen projection sending end is reduced.
In the embodiment of the application, a screen-casting receiving end receives a first input, acquires an event code corresponding to the first input and a target screen-casting sending end, and converts the event code into an initial key value corresponding to the target screen-casting sending end; and converting the initial key value into a target key value according to a data protocol of the target screen projection sending end, and sending the target key value to the target screen projection sending end, so that the screen projection sending end responds to the target key value, reverse control of the screen projection sending end at a screen projection receiving end is realized, and the dependence degree of a screen projection interaction process on the screen projection sending end is reduced.

Alternatively, the process of the screen projection process may communicate using the Miracast protocol. After the connection is successful, as shown in fig. 4, the user may reversely control the screen-casting sending terminal P1 at the screen-casting receiving terminal T, for example, the user selects a drawing application program (APP) through the touch screen, the screen-casting receiving terminal T receives the touch operation of the user, determines an event code corresponding to the touch operation, converts the event code into a target key value that can be identified by the screen-casting sending terminal P1, and further realizes drawing at the screen-casting receiving terminal T, with the effect shown in fig. 5.

In addition, the screen projection receiving end also allocates a display area for the screen projection sending end in a display interface, as shown in fig. 2, allocates a display area for each screen projection sending end, and forms an effect of displaying different screen projection contents in a split screen manner; as a fourth example, referring to fig. 6, the multi-cast screen is as shown in fig. 6, wherein the display area corresponding to each voting sender displays the same content as the display interface of the casting sender, for example, the display content may be games, news, movies, web pages, and the like.

In an alternative embodiment, the data protocol comprises the UIBC protocol; alternatively, the generic data format of the UIBC protocol may be used, and since the generic data format ignores hardware information, a device compatible with various interfaces (USB, bluetooth, etc.) may be implemented.
