Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, fig. 1 is a block diagram of a video implementation system 100 according to an embodiment of the present invention, where the video implementation system 100 includes: the system comprises a wireless screen projector 120, a control terminal 110, a local video terminal 130 and a remote video terminal 140, wherein the wireless screen projector 120 is wirelessly connected with the local video terminal 130, the wireless screen projector 120 is connected with the control terminal 110, and the local video terminal 130 is connected with the remote video terminal 140.
The control terminal 110 is configured to transmit currently played multimedia data to the local video terminal 130 through the wireless screen projector 120 for synchronous playing.
The local video terminal 130 is configured to send the multimedia data to the remote video terminal 140 for synchronous playing.
As shown in fig. 2, the wireless screen projector 120 is connected to the control terminal 110 through a USB interface 150, and the wireless screen projector 120 is connected to the local video terminal 130 through a wireless manner, such as WiFi or bluetooth, so that the wireless screen projector 120 can transmit multimedia data sent from the control terminal 110 to the local video terminal 130 through a wireless manner, and thus multimedia data can be played through the local video terminal 130 in any place in a conference room, and the problems of position limitation and incapability of remote screen projection caused by screen projection in a wired manner in the prior art are solved.
In the embodiment of the present invention, the control terminal 110 may include, but is not limited to, a portable electronic device such as a smart phone, a tablet computer, and a personal computer. The local video terminal 130 and the remote video terminal 140 may include, but are not limited to, a smart television, a desktop computer, and other display devices that support a screen-projection function.
The wireless screen projector 120 is a device that can forward multimedia data to the local video terminal 130, and the wireless screen projector 120 and the local video terminal 130 can perform data interaction through a predetermined protocol, for example, the wireless screen projector 120 establishes a connection with the local video terminal 130 through a Digital Living Network Alliance (DLNA) protocol or an Airplay protocol, or a WiFi protocol, or a bluetooth protocol.
In addition, in order to perform a long-distance video communication, the local video terminal 130 and the remote video terminal 140 establish a communication connection through a network, so that the local video terminal 130 can also synchronize to the remote video terminal 140 when performing multimedia data playing, and the remote video terminal 140 can also perform synchronous playing of the multimedia data, so that participants in a conference room can use screen projection to remotely share the multimedia data to other participants at any position, and the use experience of video sharing is improved.
It should be noted that the multimedia data may include, but is not limited to, audio, video, pictures, PPT, Word documents, and the like, which can be displayed on the control terminal 110.
Since multimedia data is generally large, in order to effectively transmit the data, the control terminal 110 may compress the currently played multimedia data into a compressed packet before transmitting the multimedia data to the wireless screen projector 120, so as to save data transmission time and improve data transmission efficiency, and then transmit the compressed packet to the wireless screen projector 120; the wireless screen projector 120 then sends the compressed packet to the local video terminal 130 in a wireless manner, and then the local video terminal 130 decompresses the received compressed packet, so as to obtain decompressed multimedia data and play the decompressed multimedia data.
The local video terminal 130 may also send the compressed packet to the remote video terminal 140, so that the remote video terminal 140 decompresses the compressed packet and plays the decompressed packet, thereby implementing synchronous playing of multimedia data by the local video terminal 130 and the remote video terminal 140.
Because the control terminal 110 has negotiated the compression algorithm and the decompression algorithm of the multimedia data with the local video terminal 130 and the remote video terminal 140 in advance, when compressing the multimedia data, the control terminal 110 can compress the multimedia data into a compression packet according to a preset compression algorithm, that is, the control terminal 110 can directly compress according to the preset compression algorithm, and after receiving the compression packet, the local video terminal 130 and the remote video terminal 140 decompress the compressed multimedia data according to the preset decompression algorithm corresponding to the preset compression algorithm, thereby saving the compression time of the control terminal 110 and the decompression time of the local video terminal 130 and the remote video terminal 140.
In addition, as an embodiment, in order to ensure the integrity of data playing, the remote video terminal 140 may further parse the received multimedia data to determine whether the multimedia data is lost, and if so, send an error signal to the local video terminal 130, where the error signal is used to instruct the local video terminal 130 to notify the control terminal 110 to resend the complete multimedia data.
Specifically, when the local video terminal 130 sends the multimedia data to the remote video terminal 140, the size of the multimedia data is carried, for example, 50M, if the size of the multimedia data found after the remote video terminal 140 analyzes the multimedia data is 49M, it indicates that the multimedia data may be lost in the sending process, at this time, an error signal is sent to the local video terminal 130, so as to inform that the multimedia data received by the local video terminal 130 is incomplete, and the local video terminal 130 needs to send the multimedia data again, then the local video terminal 130 informs the control terminal 110 that the multimedia data is incomplete, and needs to send the multimedia data again, then the control terminal 110 can send the multimedia data to the local video terminal 130 again, and then the local video terminal 130 sends the multimedia data to the remote video terminal 140 again.
Of course, the integrity of the multimedia data may be detected in other manners, such as detecting whether the data packets of the multimedia data are missing or not, detecting whether the data packets of the multimedia data are sent in sequence, and the like, and all other manners of detecting the integrity of the multimedia data are included in the scope of the present invention.
As an implementation manner, in the screen projection process of the local video terminal 130 by the control terminal 110, the control terminal 110 may further receive a first preset operation performed by a user on the control terminal 110, monitor the first preset operation, determine a first instruction corresponding to the first preset operation, determine, based on the first instruction, first screen projection information corresponding to multimedia data currently played by the control terminal 110, and send the first screen projection information to the local video terminal 130 through the wireless screen projector 120, so that the local video terminal 130 plays the multimedia data based on the first screen projection information.
Specifically, the first preset operation may be preset by the control terminal 110 through a client, such as a video client, for example, when the control terminal 110 starts the corresponding video client and clicks a video played on the video client, the control terminal 110 may enter a capturing process of the first preset operation, that is, may monitor the operation of the user, and when it is monitored that the user performs the first preset operation on the control terminal 110, a first instruction corresponding to the first preset operation may be determined according to the first preset operation, where the first instruction is used to instruct to trigger the control terminal 110 to perform screen projection on the local video terminal 130, that is, to send the multimedia data to the local video terminal 130 through the wireless screen projector 120.
The first preset operation is a non-touch screen operation executed by the control terminal 110, and it should be noted that the first preset operation may be set by a user in a self-defined manner, for example, the first preset operation may be to flick the control terminal 110 once, or to flick the control terminal 110 twice continuously, or to directly perform click triggering on a display page of the control terminal 110, and the like.
In addition, the first preset operation may also be an operation of establishing a connection between the wireless screen projector 120 and the control terminal 110, for example, when the control terminal 110 detects that the wireless screen projector 120 is inserted into the control terminal 110 through the USB interface, the control terminal 110 detects the first preset operation, that is, the connection between the wireless screen projector 120 and the control terminal 110 is performed, so that the control terminal 110 can project a screen to the local video terminal 130 through the wireless screen projector 120.
In the embodiment of the present invention, for monitoring the first preset operation by the control terminal 110, a gyroscope built in the control terminal 110 may be used for implementation, and specifically, when the user performs the first preset operation on the control terminal 110, such as swinging the control terminal 110 once, the strength and the distance of the swinging of the control terminal 110 may be monitored by the gyroscope built in the control terminal 110, and whether the user performs the first preset operation on the control terminal 110 is determined according to the strength and the distance of the swinging. Here, the swinging force range and the distance range of the control terminal 110 corresponding to the first preset operation need to be preset, and when the swinging force range and the distance range of the control terminal 110 are detected to be respectively located in the preset swinging force range and the preset distance range of the control terminal 110 corresponding to the first preset operation, it can be determined that the user has performed the corresponding first preset operation on the control terminal 110.
The first screen projection information at least includes index information of the multimedia data or the multimedia data, and of course, the first screen projection information may also include play progress information of the multimedia data.
The index information of the multimedia data may include link information, local address information, or identification information that can identify the address information, and the like, which is not limited herein in the embodiments of the present invention. For example, when the multimedia data is a video, the link information corresponding to the video may be clicked through the link information provided by the server to obtain a played video, and then the video is subsequently sent to the local video terminal 130; the identification information capable of identifying the address information can be identified to determine the address information, and then the played video is obtained through the determined address information, so that the video is sent to the local video terminal 130 subsequently; or the played video can be directly obtained through the local address information, and then the video is subsequently sent to the local video terminal 130; when the multimedia data is a picture, the picture can be directly sent to the local video terminal 130. Therefore, the local video terminal 130 plays the multimedia data based on the obtained first screen projection information.
In addition, after the control terminal 110 sends the first screen-casting information to the local video terminal 130, the control terminal 110 is further configured to monitor a second preset operation of the user on the control terminal 110, determine a second instruction corresponding to the second preset operation, and control the playing progress of the multimedia data played by the local video terminal 130 based on the first screen-casting information based on the second instruction, or control the control terminal 110 to perform the next screen-casting to the local video terminal 130 after the multimedia data is played.
Here, in the process of performing screen projection on the local video terminal 130, after the control terminal 110 receives the feedback information of successful screen projection generated based on the first screen projection information and sent by the local video terminal 130, the capture process of the second preset operation may be entered. For example, when the local video terminal 130 plays the multimedia data, if the control terminal 110 monitors that the user performs a second preset operation on the multimedia data, a second instruction corresponding to the second preset operation may be determined according to the second preset operation, and the playing progress of the multimedia data played by the local video terminal 130 is controlled through the second instruction. For example, if the control terminal 110 monitors that the user performs a second preset operation on the control terminal 110, such as swinging the control terminal 110 laterally, the control terminal 110 may generate a seek (seek) instruction and transmit the seek instruction to the local video terminal 130, and the local video terminal 130 may implement operation functions of fast forward, fast backward, volume control, and the like on the multimedia data playing based on the seek instruction. For example, if the control terminal 110 is swung to the left and horizontally, the multimedia data played by the local video terminal 130 can be controlled to fast backward; by swinging the control terminal 110 to the right, the multimedia data played by the local video terminal 130 can be correspondingly controlled to be fast-forwarded.
When the playing of the multimedia data on the local video terminal 130 is finished, if the control terminal 110 monitors that the user performs the second preset operation on the multimedia data, the second instruction corresponding to the second preset operation may be determined according to the second preset operation, and the control terminal 110 is controlled to perform the next screen projection on the local video terminal 130 through the second instruction. Here, taking multimedia data as an example of video, when the control terminal 110 makes the next screen projection to the local video terminal 130, the local video terminal 130 will play the next video, which may include a new video and the current video being played. Specifically, the new video may include the next video, the next video or the previous video, etc., and if the local video terminal 130 plays the current video again, the playback of the current video is performed. For example, if the projected video is a tv series, the control terminal 110 may play the next episode of the tv series when performing the next screen projection; if the projected video is an integrated art program, the control terminal 110 may play the next stage of the integrated art program when performing the next screen projection; if the projected video has no corresponding next period, next set or previous set, previous period, the control terminal 110 may determine the video that the user may like according to the historical playing data and the type of the current video being played, recommend the determined video to the user, and control the local video terminal 130 to automatically play the recommended video.
For example, in one embodiment, the control terminal 110 may be controlled to play the next set or the next period of the current video by swinging the control terminal 110 laterally to the right, and then the next set or the next period of the current video played by the control terminal 110 is projected onto the local video terminal 130 for playing; the control terminal 110 may also be controlled to play the previous video collection or period by swinging the control terminal 110 laterally to the left, and then the previous video collection or period played by the control terminal 110 is projected onto the local video terminal 130 for playing. Of course, in another embodiment, the control terminal 110 may be controlled to perform the next screen projection to the local video terminal 130 only by the second instruction, but the present disclosure is not limited thereto, as to whether the local video terminal 130 plays the multimedia data projected by the control terminal 110.
It should be noted that the second preset operation may be set by a user in a customized manner, for example, the second preset operation may be laterally swinging the control terminal 110 leftward or rightward, or may also be any other non-touch screen operation performed on the control terminal 110, which is not limited herein.
