Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and more specific, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The embodiment provides a screen projection control method, through the method of the embodiment, when screen projection control is performed, when interface switching is encountered, switching display information is sent to display equipment, so that the display equipment can perform screen projection display based on the switching display information, the whole screen projection video is not sent to the display equipment, the video transmission data volume can be reduced, and the real-time performance and fluency of screen projection transmission are optimized. In specific implementation, the embodiment firstly acquires screen projection picture information, and determines a real-time picture state according to the screen projection picture information; if the real-time picture state is interface switching, acquiring switching display information corresponding to the interface switching; and sending the switching display information to a display device to control the display device to perform interface switching according to the switching display information. Therefore, the embodiment does not need to send the whole screen-throwing video to the display device, and only needs to send the switching display information for reflecting the display parameters to the display device, so that the display device can display the screen-throwing interface switching process based on the switching display information without causing short-time data increase.
For example, when the mobile phone device (i.e. the source device) drops the displayed screen content to the television device (i.e. the display device), the screen dropping screen information of the mobile phone a device starts to be acquired, where the screen dropping screen information reflects the screen content displayed on the mobile phone device at the moment. Therefore, the real-time picture state can be determined according to the screen-throwing picture information, the real-time picture state at the moment reflects whether the picture displayed on the mobile phone equipment is subjected to interface switching, and if the real-time picture state is the interface switching, the mobile phone equipment is indicated to play the animation between the two interface switching at the moment. Therefore, the example will acquire the switching display information corresponding to the interface switching, where the switching display information reflects the playing parameters of the animation between the two interface switching on the mobile phone device at this time, after the mobile phone device acquires the switching display information, the switching display information will be sent to the television device, and after the television device receives the switching display information, the television device will realize the switching between the two interfaces based on the switching display information. Therefore, the mobile phone equipment does not record the video of the switching between the two interfaces played by the mobile phone equipment to the television equipment, but sends the switching display information to the television equipment, so that the data volume of the video transmission is reduced, and the video smoothness between the mobile phone equipment and the television equipment is ensured.
Exemplary method
The screen projection control method in the embodiment can be applied to terminal equipment, and the terminal equipment can be intelligent terminal products such as televisions, computers and mobile phones. As shown in fig. 1, the screen projection control method in this embodiment includes the following steps:
and step S100, acquiring screen projection picture information, and determining a real-time picture state according to the screen projection picture information.
Because the embodiment needs to obtain the corresponding switching display information so as to send the switching display information to the display device when the interface of the terminal device is switched, the embodiment needs to obtain the screen projection screen information of the terminal device, and then determines the real-time screen state according to the obtained screen projection screen information. In this embodiment, the screen information reflects the screen content displayed on the terminal device (such as the mobile phone device in the above example). Therefore, the real-time picture state can be determined according to the screen-throwing picture information, and the real-time picture state at the moment reflects whether the picture displayed on the terminal equipment at the moment has interface switching or not.
In one implementation manner, when determining the real-time picture status, the method in this embodiment includes the following steps:
step S101, acquiring the screen projection picture information, and determining a display image according to the screen projection picture information;
step S102, determining the real-time picture state according to the display image.
Specifically, after the terminal device of this embodiment obtains the screen-throwing picture information, a display image is obtained from the screen-throwing picture information, where the display image is the picture content displayed by the terminal device at this time, then it is further determined whether the display image at this time changes, and if so, it is indicated that the real-time picture state at this time is interface switching. For example, a user uses a mobile phone device to perform screen projection of PPT playing, and when the switching process of each page of PPT involves interface switching, even if the content in the same page of PPT changes, such as increasing or decreasing, interface switching is involved. If the display image changes, determining that the real-time picture state information is interface switching; and if the display image is not changed, determining that the real-time picture state information is that the interface is not switched.
And step 200, if the real-time picture state is interface switching, acquiring switching display information corresponding to the interface switching.
In this embodiment, if the real-time picture state of the terminal device is interface switching, it is indicated that the terminal device will perform switching between two interfaces at this time, and in order to reduce the data volume of the screen-throwing transmission, the terminal device in this embodiment does not perform screen recording operation on the whole interface switching process, but directly obtains switching display information, where the switching display information is used to implement parameters of switching between two interfaces.
In one implementation manner, the method for acquiring the switching display information in this embodiment includes the following steps:
step S201, if the real-time picture state is interface switching, acquiring a switched target interface;
step S202, determining a switching mode corresponding to the target interface based on the target interface;
step 203, determining a switching time corresponding to the switching mode according to the switching mode;
and step S204, taking the target interface, the switching mode and the switching time as the switching display information.
In this embodiment, a socket transmission channel is provided between the terminal device and the display device for transmitting video data, and the transmitted video coding packet is expanded, and when the real-time picture status is that the interface is not switched, the terminal device will record the screen, and send the video coding packet obtained by recording the screen to the display device. When the real-time picture state is interface switching, the terminal equipment stops local screen recording operation at the moment, and the terminal equipment still performs interface switching at the moment, namely, the conversion between the two interfaces is realized, and only the screen recording operation is not performed, so that video data when the two interfaces are switched is not obtained. At this time, the terminal device may acquire a target interface after completing the interface switching, where the target interface is a still picture after completing the interface switching. After the target interface is obtained, the terminal device in this embodiment further obtains a switching mode corresponding to the target interface based on the target interface. In this embodiment, since the switching between the two interfaces is already completed at the terminal device, a corresponding switching mode can be obtained while the target interface is obtained, where the switching mode may be a mode of "fade-in and fade-out", "fly-in", etc., which is reflected in how the old interface disappears and how the new interface appears. When the switching manner is obtained, the embodiment may further determine, based on the switching manner, a switching time corresponding to the switching manner, where the switching time refers to a time taken to implement switching between two interfaces by using the switching manner. In one implementation manner, in this embodiment, a mapping relationship between a switching manner and a switching time is preset, for example: the 3 seconds of the gradual in and gradual out, the reflected time for realizing the switching between the two interfaces by using the switching mode of the gradual in and gradual out is 3 seconds. Therefore, after the terminal device in this embodiment obtains the switching manner, the switching manner is matched with the preset mapping relationship, so that the switching time corresponding to the switching manner can be obtained. After the target interface, the switching mode and the switching time are obtained, the embodiment can take the target interface, the switching mode and the switching time as the switching display information. Therefore, in the embodiment, only three parameters in the switching display information are obtained, so that the data volume is greatly reduced, and only the three parameters are required to be transmitted when the switching display information is transmitted to the display device in the subsequent step.
In one implementation, the switching mode in this embodiment may be set as encoded information, which may be numbers, letters, or a combination of numbers and letters. For example, the code 1 corresponding to the fade-in and fade-out, and the code 2 corresponding to the fade-in and fade-out are flown. In this embodiment, the switching manner is set to the encoded information, so that the amount of data included in the switching display information is further reduced, and therefore, the amount of data is not increased when the switching display information is transmitted to the target device, and is greatly reduced compared with the conventional video data.
And step S300, the switching display information is sent to display equipment so as to control the display equipment to switch interfaces according to the switching display information.
After the terminal equipment obtains the switching display information, the terminal equipment sends the switching display information to the display equipment, and the display equipment realizes switching of the two interfaces according to the switching display information after receiving the switching display information. The switching display information is obviously reduced in data volume relative to the video data, so that the display device does not have the phenomenon of blocking and delaying when performing screen-casting display and interface switching. In one implementation, since the switching mode in the switching display information is the coding information, the display device can obtain the coding information for reflecting the switching mode after receiving the switching display information, and then find the corresponding switching mode according to the coding information, so as to realize interface switching according to the switching mode. Therefore, in this embodiment, the correspondence between the switching mode and the encoded information is stored in the display device in advance, so that the display device can directly obtain the corresponding switching mode based on the encoded information. After the terminal equipment finishes the transmission of the switching display information, the terminal equipment resumes the local screen recording operation, continues to record the screen, and then transmits the video obtained by the screen recording to the display equipment for screen casting display.
In summary, in this embodiment, first, screen projection screen information is acquired, and a real-time screen state is determined according to the screen projection screen information; if the real-time picture state is interface switching, acquiring switching display information corresponding to the interface switching; and sending the switching display information to a display device to control the display device to perform interface switching according to the switching display information. When the screen projection control is performed, when the interface is switched, the switching display information is sent to the display device, so that the display device can perform screen projection display based on the switching display information, the whole screen projection video is not sent to the display device, the video transmission data volume can be reduced, and the real-time performance and fluency of the screen projection transmission are optimized.
Exemplary apparatus
Based on the above embodiment, the present invention further provides a screen projection control device, as shown in fig. 2, where the device includes: the system comprises a state acquisition module 10, an information acquisition module 20 and a screen projection control module 30. Specifically, the state acquisition module 10 in this embodiment is configured to acquire screen-projection screen information, and determine a real-time screen state according to the screen-projection screen information. The information obtaining module 20 is configured to obtain switching display information corresponding to the interface switching if the real-time picture state is the interface switching. The screen-throwing control module 30 is configured to send the switching display information to a display device, so as to control the display device to perform screen-throwing control according to the switching display information.
The screen-throwing control device is provided with terminal equipment, and when interface switching occurs in the terminal equipment, corresponding switching display information is acquired so as to send the switching display information to the display equipment. In this embodiment, the screen information reflects the screen content displayed on the terminal device (such as the mobile phone device in the above example). Therefore, the real-time picture state can be determined according to the screen-throwing picture information, and the real-time picture state at the moment reflects whether the picture displayed on the terminal equipment at the moment has interface switching or not.
Specifically, after the terminal device of this embodiment obtains the screen-throwing picture information, a display image is obtained from the screen-throwing picture information, where the display image is the picture content displayed by the terminal device at this time, then it is further determined whether the display image at this time changes, and if so, it is indicated that the real-time picture state at this time is interface switching. For example, a user uses a mobile phone device to perform screen projection of PPT playing, and when the switching process of each page of PPT involves interface switching, even if the content in the same page of PPT changes, such as increasing or decreasing, interface switching is involved. If the display image changes, determining that the real-time picture state information is interface switching; and if the display image is not changed, determining that the real-time picture state information is that the interface is not switched.
In this embodiment, a socket transmission channel is provided between the terminal device and the display device for transmitting video data, and the transmitted video coding packet is expanded, and when the real-time picture status is that the interface is not switched, the terminal device will record the screen, and send the video coding packet obtained by recording the screen to the display device. When the real-time picture state is interface switching, the terminal equipment stops local screen recording operation at the moment, and the terminal equipment still performs interface switching at the moment, namely, the conversion between the two interfaces is realized, and only the screen recording operation is not performed, so that video data when the two interfaces are switched is not obtained. At this time, the terminal device may acquire a target interface after completing the interface switching, where the target interface is a still picture after completing the interface switching. After the target interface is obtained, the terminal device in this embodiment further obtains a switching mode corresponding to the target interface based on the target interface. In this embodiment, since the switching between the two interfaces is already completed at the terminal device, a corresponding switching mode can be obtained while the target interface is obtained, where the switching mode may be a mode of "fade-in and fade-out", "fly-in", etc., which is reflected in how the old interface disappears and how the new interface appears. When the switching manner is obtained, the embodiment may further determine, based on the switching manner, a switching time corresponding to the switching manner, where the switching time refers to a time taken to implement switching between two interfaces by using the switching manner. In one implementation manner, in this embodiment, a mapping relationship between a switching manner and a switching time is preset, for example: the 3 seconds of the gradual in and gradual out, the reflected time for realizing the switching between the two interfaces by using the switching mode of the gradual in and gradual out is 3 seconds. Therefore, after the terminal device in this embodiment obtains the switching manner, the switching manner is matched with the preset mapping relationship, so that the switching time corresponding to the switching manner can be obtained. After the target interface, the switching mode and the switching time are obtained, the embodiment can take the target interface, the switching mode and the switching time as the switching display information. Therefore, in the embodiment, only three parameters in the switching display information are obtained, so that the data volume is greatly reduced, and only the three parameters are required to be transmitted when the switching display information is transmitted to the display device in the subsequent step.
In one implementation, the switching mode in this embodiment may be set as encoded information, which may be numbers, letters, or a combination of numbers and letters. For example, the code 1 corresponding to the fade-in and fade-out, and the code 2 corresponding to the fade-in and fade-out are flown. In this embodiment, the switching manner is set to the encoded information, so that the amount of data included in the switching display information is further reduced, and therefore, the amount of data is not increased when the switching display information is transmitted to the target device, and is greatly reduced compared with the conventional video data.
After the terminal equipment obtains the switching display information, the terminal equipment sends the switching display information to the display equipment, and the display equipment realizes switching of the two interfaces according to the switching display information after receiving the switching display information. The switching display information is obviously reduced in data volume relative to the video data, so that the display device does not have the phenomenon of blocking and delaying when performing screen-casting display and interface switching. In one implementation, since the switching mode in the switching display information is the coding information, the display device can obtain the coding information for reflecting the switching mode after receiving the switching display information, and then find the corresponding switching mode according to the coding information, so as to realize interface switching according to the switching mode. Therefore, in this embodiment, the correspondence between the switching mode and the encoded information is stored in the display device in advance, so that the display device can directly obtain the corresponding switching mode based on the encoded information. After the terminal equipment finishes the transmission of the switching display information, the terminal equipment resumes the local screen recording operation, continues to record the screen, and then transmits the video obtained by the screen recording to the display equipment for screen casting display.
