Based on the above mobile terminal hardware structure and the communication network system, various embodiments of the method of the present invention are provided.
Fig. 3 is a flowchart of an embodiment of a file transfer control method provided in the present application. Once triggered by a user, the process in this embodiment automatically operates through the mobile terminal, where each step may be performed sequentially as shown in the flowchart, or may be performed simultaneously according to a plurality of steps in actual situations, which is not limited herein. The file transmission control method provided by the application comprises the following steps:
step S310, acquiring a screen-throwing video stream, and sending the screen-throwing video stream to the display equipment through the screen-throwing connection channel so that the display equipment can display the content corresponding to the screen-throwing video stream;
step S320, receiving a file transmission instruction, and determining a target file sent to the display device;
Step S330, determining transmission parameters of a screen-throwing connection channel;
step S340, in response to the transmission parameter, determining a transmission timing for controlling the transmission of the target file to the display device.
Through the embodiment, the problem of screen throwing and blocking caused by sending larger files can be avoided to the greatest extent, and the user experience is improved better.
The above steps will be specifically described with reference to specific embodiments.
In step S310, a cast video stream is acquired.
Specifically, a screen-throwing connecting channel is established between the mobile terminal and the display equipment, and the mobile terminal and the display equipment realize the screen-throwing effect through the screen-throwing connecting channel. After the mobile terminal and the display device establish screen projection, the mobile terminal can display the content in the display interface of the mobile terminal in the display device. In this embodiment, the display device may be a device with a display screen having communication capability, for example, a notebook computer. The mobile terminal acquires the display content of the current interface in real time and packages the display content into a data packet to form a screen-throwing video stream, and the screen-throwing video stream is sent to the display device through the screen-throwing connection channel so that the display device can display the content corresponding to the screen-throwing video stream. It should be noted that, in the process of sending the screen-projection video stream to the display device through the screen-projection connection channel, a certain bandwidth of the connection channel needs to be occupied, so that the bandwidth provided for transmitting the screen-projection video stream determines the screen-projection effect on the display device, for example, if the bandwidth is insufficient, the screen-projection screen is blocked.
In step S320, a file transfer instruction is received, and a target file sent to the display device is determined.
In particular, the file transfer instruction is to transfer file data other than user interface content for presenting the mobile terminal on the display device. In this embodiment, step S320 may be to receive a backup instruction, where the backup instruction is used to trigger the mobile terminal to send the backup file to the display device. Specifically, when the mobile terminal performs screen projection with the display device, a user operates the mobile terminal to perform data backup to the display device, and when the mobile terminal receives a backup instruction, the data to be backed up is prepared as a target file. When the file transmission instruction is received, the backup operation is not performed immediately after the target file is prepared, and the specific timing for sending the target file to the display device is determined according to the transmission parameters determined in the subsequent steps.
In step S330, transmission parameters of the screen-drop connection channel are determined.
Specifically, in an alternative embodiment, the transmission parameters of the screen-throwing connection channel may be determined by calculating the transmission parameters once at preset time intervals, and then storing the current latest transmission parameters. When the subsequent steps need to be executed, the current latest transmission parameters are directly used. In an alternative embodiment, step S330 may trigger the step of determining the transmission parameters after the screen-on connection channel is established. In an alternative embodiment, step S330 may trigger execution when a file transfer instruction is received.
In an alternative embodiment, step S330 may include the steps of:
in step S3301, a data volume type of the video stream is determined, where the data volume type is a type determined according to a size of the data volume.
Step S3302, determining channel communication quality of a screen-projection connection channel between the mobile terminal and the display device.
And step S3303, determining the transmission parameter according to the data volume type and the channel communication quality.
By the implementation mode, whether the current transmission channel has enough broadband to support file transmission can be accurately determined, and the screen throwing effect is not affected.
Specifically, in step S3301, during the screen-casting process, the data amounts of different screen-casting video streams are different, which results in that the bandwidths required for the different screen-casting video streams may be different, or the tolerance of the user to the screen-casting effect may be different. The data size type represents the size of the data size of the current screen-drop view stream. In the present embodiment, step S3301 may include the steps of:
step S33011, acquiring a currently running application type, where the application type includes at least one of the following: game classes, video classes, social classes, and text editing classes;
And step S33012, determining the data volume type of the screen-throwing video stream according to the application program type.
Wherein, the data volume of the video stream of the screen-throwing generated by the mobile terminal running different application programs is different. For example, the method can be used for entering a calendar, weather and other small applications, and larger data are not needed for screen projection. In this embodiment, the application type includes at least one of the following: game classes, video classes, social classes, and text editing classes. In implementation, the data volume types corresponding to different application programs may be preset, for example, the data volume represented by the data liner type corresponding to the game application program is large, and the data volume represented by the data liner type corresponding to the text editing program is small. The mobile terminal detects the application package name of the currently opened application program, determines the type of the application program through the application package name, and can determine that the data volume required by screen projection is smaller when judging that the application program is opened like a calendar, weather and the like, thereby determining the corresponding data volume type.
According to the embodiment, when the application program of which the opening instruction is received currently or the running application program is detected, the data size of the screen projection video stream in the screen projection process can be predicted, and further the data size can be rapidly used as a judging basis for whether to send the target file or not, so that the calculation efficiency is improved.
In step S3302, the screen-projection connection channel may be a bluetooth connection channel between the mobile terminal and the display device, or a wireless connection channel, or a combination of the bluetooth connection channel and the wireless connection channel. The connection channel has the problem of data transmission rate in the connection process, namely, the faster the data transmission rate is, the better the channel quality is represented, and the slower the data transmission rate is, the worse the channel quality is represented. It should be noted that the basis for evaluating the quality of the channel may be various, and is not particularly limited. In the present embodiment, step S3302 may include the following steps:
step S33021, counting the transmission time of a preset number of screen-throwing video streams transmitted to the display equipment;
and step S33022, determining the channel communication quality according to the sending time.
Specifically, the present invention relates to a method for manufacturing a semiconductor device. The channel communication quality is divided into good quality and poor quality. When the method is implemented, the data of the frame sent by the socket of the display equipment is statistically monitored, and the statistics is carried out once every 1 ten thousand frames, so that the network speed is very slow when the judgment time is longer, and the channel communication quality is better when the judgment time required for throwing the 1 ten thousand frames is shorter.
By the embodiment, the network quality can be determined in real time, and the accuracy and the instantaneity of the judged channel communication quality are improved, so that the sending time of the target file meeting the current situation can be made.
In step S3303, transmission parameters are determined comprehensively according to the data size type and the channel connection quality, so as to determine the timing of transmitting the target file. In the present embodiment, step S3303 may include the steps of:
step S33031, determining a number identifier corresponding to the data volume type, where the number identifier includes a first identifier and a second identifier, the first identifier indicates that the corresponding data type is smaller in data volume, and the second identifier indicates that the corresponding data type is larger in data volume;
step S33032, determining a quality identifier corresponding to the channel communication quality, wherein the quality identifier comprises a third identifier and a fourth identifier, the third identifier indicates that the corresponding channel communication quality is better, and the fourth identifier indicates that the corresponding channel communication quality is worse;
step S33033, determining a combination of the number identifier of the current data volume type and the instruction identifier of the current channel communication quality as the transmission parameter.
Specifically, marks corresponding to different data volume types and quality marks corresponding to different channel communication qualities are preset, and when the method provided by the application operates, the combination of the number marks and the quality marks is determined to serve as a current transmission parameter. For example, after the mobile terminal and the computer screen are established, the mobile terminal detects the name of an application package opened by the current user, and when judging that the application is opened like a calendar, weather and the like, the mobile terminal can judge that the data volume required by the screen is smaller, and then determine that the quantity mark is a mark A; the method comprises the steps of carrying out statistics monitoring on screen-end socket sending frame data of a screen, counting once every 1 ten thousand frames, determining that the quality mark is a mark B1 when judging that the time required for the screen-throwing of 1 ten thousand frames is short and the network speed is good, and further determining that the transmission parameters are A and B1, that is, the occupied bandwidth of a current screen-throwing connecting channel is small and the network transmission speed is high, so that the method is suitable for sending target files. If the transmission parameters are other combinations, the transmission target file is not suitable.
In step S340, a transmission timing to control transmission of the target file to the display device is determined in response to the transmission parameter.
Specifically, the transmission opportunity refers to when the target file is transmitted to the display device. And determining the time for sending the target file to the display device according to the conditions of different transmission parameters. In this embodiment, determining a transmission timing to control transmission of the target file to the display device includes at least one of: controlling the target file to be immediately sent to the display equipment after receiving the file transmission instruction; and controlling the target file to be delayed to be sent to the display equipment after receiving the file transmission instruction.
