Optionally, the screen projection control device may further include a camera, a Radio Frequency (RF) circuit, a sensor, an audio circuit, a WiFi module, and the like. The television performs communication with other devices via the network interface 1004.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the projection control device and may include more or fewer components than shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, the memory 1005 may include an operating system, a network communication module, a user interface module, and a screen projection program.
In the terminal shown in fig. 1, the network interface 1004 is mainly used for connecting to a backend server and performing data communication with the backend server; the user interface 1003 is mainly used for connecting a client (user side) and performing data communication with the client; and the processor 1001 may be configured to call a screen projection program stored in the memory 1005 and perform the following operations:
receiving a screen projection instruction which is sent by a first terminal and carries first content;
responding to the screen projection instruction, and judging whether target content exists or not, wherein the target content is the same as the first content picture, and the quality dimension of the target content is larger than that of the first content;
and if the target content exists, performing display operation on the target content.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating an embodiment of a screen projection method according to the present application, wherein the screen projection method includes the following steps:
step S10, receiving a screen projection instruction which is sent by a first terminal and carries first content;
the first terminal is a delivery device for delivering the current playing content to other equipment, such as a mobile phone, a tablet computer, a notebook computer and the like; the screen projecting end is a terminal capable of receiving a screen projecting instruction sent by the first terminal, obtaining first content sent by the first terminal according to the screen projecting instruction, and projecting the first content to a display interface, such as a computer, a television, a smart screen, a tablet and the like. The screen projecting end receives a screen projecting instruction of first content carried by a first terminal connected with the screen projecting end, and the first content is projected to a display interface according to the screen projecting instruction. For example, when a television receives a screen projection instruction sent by a mobile phone which establishes a connection in the same WiFi environment, first content carried by the screen projection instruction is acquired and played. The screen projecting instruction is an instruction which is sent to a screen projecting end by the first terminal so that the screen projecting end receives the instruction and finishes the projection of the first content according to the instruction; the first content is the content sent by the first terminal to the screen projection end for projection, the content can be directly sent to the screen projection end or the address information of the first content is obtained at the first terminal when the screen projection end receives the address information, the address information is obtained, and then the projection of the first content is completed, and the screen projection end can be connected with the first terminal through wireless WIFI, Bluetooth and the like to receive the information sent by the first terminal.
Step S20, responding to the screen projection instruction, judging whether a target content exists, wherein the target content is the same as the first content picture, and the quality dimension of the target content is larger than that of the first content picture;
the screen projecting end responds to a screen projecting instruction of the first terminal, obtains parameter information of the first content according to the first content projected by the first terminal, and judges whether target content which is the same as a first content picture and has a quality dimension higher than that of the first content exists or not according to the parameter information.
It can be understood that the screen projecting end receives the first content projected by the first terminal after establishing connection with the first terminal, and searches whether the target content same as the first content picture exists while displaying the first content. The quality dimension is a parameter for measuring the first content and the attribute of the picture (picture) such as resolution, definition, color depth, format and the like of the target content. The screen projection terminal can search whether the target content identical to the first content picture exists in a local database and a server according to the first content. Optionally, whether the content identical to the picture exists in the local database may be searched according to the first content picture information, and then the quality dimension of the content picture is determined, and then whether the target content exists in the local database is determined according to the determination result.
And step S30, if the target content exists, performing display operation on the target content.
When the screen projection end determines that the content with the quality dimension higher than that of the first content picture and the same as the first content picture exists, the content is determined to be the target content capable of replacing the first content, and the target content is displayed on the screen projection end according to the display rule, wherein the quality dimension is parameters measuring the image playing quality of the playing content (including the first content and the second content), such as color depth, resolution ratio and the like.
Optionally, when it is determined that the target content exists, it may be determined whether the target content needs to be delivered on a screen delivery side by receiving a first operation instruction. The first operation instruction is an instruction of whether the user allows the target content to be displayed at the screen projection end. When the target content exists, the information of whether the target content superior to the first content in quality dimension is selected or not can be sent to the first terminal in a popup mode at the screen projection end, so that the user can send the first operation instruction, and when the first operation instruction is an instruction that the user allows the target content to be displayed at the screen projection end, the operation of displaying the target content at the screen projection end is executed.
Optionally, the target content may be sent to the first terminal, for example, when the target content is a picture, the screen projection end may push the picture information when pushing the target content to the first terminal; when the target content is a video, a video frame which is the same as a video frame displayed at the screen projection end at present can be intercepted and sent to the first terminal, and the intercepted video frame is a video frame (a first content frame) played by the screen projection end and is superior to the video frame which is projected from the first terminal to the screen projection end in quality dimension. When the target content is delivered to the first terminal, a second operation instruction is received, the second operation instruction is an instruction for judging whether the user allows the target content to be displayed on the screen-projecting end, and if the second operation instruction is judged that the user allows the operation content to be displayed on the screen-projecting end, the target content is delivered to the screen-projecting end to replace the first content. It should be noted that, when the first content is a video, and the screen-casting end receives an instruction for determining to cast the target content, that is, the first content currently being cast is replaced by the target content for playing, the playing information (the playing position of the first content) of the current first content at the screen-casting end is obtained, and the starting position of the playing of the target content is shifted to the position of the playing of the first content.
In the application, after the target content is sent to the first terminal, the first terminal can execute the action of sharing the target content, and the target content can be shared by back-delivering the target content to the first terminal. For example, a video (target content) which is back-cast to a mobile phone on a television is sent to a friend by Wechat through an instant chat tool. It is worth noting that if the first content which is currently put is the picture content, the screen throwing end directly throws the picture back to the first terminal; and if the currently released first content is the video content, the screen releasing end releases the video frame or the video address information of the currently played content to the first terminal.
The specific implementation process of this embodiment may be, for example, that a user needs to put video information currently played using an Tencent video from a mobile phone (a first terminal) onto a television for playing, the user may establish a connection with the television through a local area network and send a screen-throwing instruction carrying the video information to the television, and the television receives the screen-throwing instruction, obtains a position watched by the user on the mobile phone, and jumps to the playing position. Meanwhile, a picture of the video is intercepted, a currently played video is known as a Tang people street quest through obtaining first parameter information (the fact that actors in the drama or a specific scene can be identified) in the picture, a related video of the Tang people street quest is obtained, parameters such as definition and color depth of the related video are obtained, the related video is screened according to the parameters and compared with the currently played video in quality dimension, if the video is better than the video which is currently transmitted to a television through a mobile phone, a message of whether to replace the video is sent to the mobile phone is sent, and when a received instruction is replacement, the played video of the current terminal is replaced by the clearer video.
In this embodiment, when the screen projection end receives a screen projection instruction of the first terminal, the first content delivered by the first terminal is acquired, whether target content superior to the first content in quality dimension exists or not is determined according to the first content, and when the target content exists, the first content currently delivered by the screen projection end is replaced with the target content. By the method, the content which is thrown to the screen throwing end by the first terminal can be replaced by the content with higher quality displayed on the screen, and the user does not need to manually search and replace the content, so that the step of obtaining the content with higher quality is simplified, and the intelligence of screen throwing is improved.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating a process of determining whether target content exists according to another embodiment of the present application, including:
step S21, finding a second content in a first database according to a first parameter set corresponding to the first content, where the first parameter set is a parameter reflecting a content picture;
step S22, if a plurality of second contents are obtained, obtaining a first sequence composed of the plurality of second contents;
step S23, determining a target sequence according to the first sequence, and sending the target sequence to the first terminal;
step S24, receiving a third operation instruction sent by the first terminal, where the third operation instruction is an instruction sent by a user through the first terminal according to the target sequence, and selecting a certain second content in the target sequence as the target content according to the third operation instruction.
In this embodiment, when the screen projecting end receives a first content carried by a screen projecting instruction of the first terminal, a first parameter set of the first content is acquired and searched in the first database, where the first parameter set is a parameter reflecting a content picture, where the first parameter set includes parameters of a name, a director, an actor, a dialog, a format, a duration, and the like when the projected content picture is a video picture, and the first parameter set includes parameters representing picture attributes such as a resolution, a color depth, a format, a picture name, and the like when the projected content picture is a picture. The screen projection end searches local data D1 (a first database) according to the acquired first parameter set of the first content to obtain second content, when a plurality of second contents exist, a first sequence formed by the plurality of second contents is acquired, the contents of the first sequence are further screened to determine a target sequence, and the target sequence is sent to the first terminal, so that a user can determine a certain second content capable of replacing the currently played first content in the target sequence as the target content. After the user determines the target content, a third operation instruction is sent to the screen projection end at the first terminal, so that the screen projection end determines the target content according to the third operation instruction.
It can be understood that, since the content information of the first sequence is obtained according to the first parameter set of the first content delivered from the first terminal to the screen-projecting end for playing, the content of the first sequence is similar to or identical to the picture of the first content. For example, when the content picture of the first content played by the screen projection end is a certain actor, the face information and/or dressing information of the actor are acquired and searched based on the first database to obtain a plurality of second contents similar to the actor, and the plurality of second contents form a first sequence. A set of contents made up of a plurality of second contents is referred to as a sequence in this application. Wherein the first sequence is a sequence formed by a plurality of second contents acquired in the first database based on the first parameter set of the first content.
When a target sequence formed by a plurality of second contents is sent to the first terminal, the second contents can be sequenced according to the quality of the second contents in the target sequence, so that a user can select the target contents according to the sequence of the second contents.
Optionally, when the number of the second content found in the first database is smaller than or equal to the preset threshold, a search needs to be performed in the second database (D2 in the database operated by the server), and the second content found in the second database is supplemented into the first sequence. For example, when the first content is a picture, the screen projection terminal acquires a first parameter set of the picture to search in a local database, acquires the picture related to the first parameter set as a second content, and when a plurality of second contents exist, acquires the plurality of second contents to form a first sequence. Wherein, the quantity of the second content can be set by the user. For example, when the first content is a picture, the preset threshold is 20, when the number of the second content searched by searching the local data D1 is less than or equal to 20, the second content is searched and supplemented in the database operated by the server according to the first parameter set D2, and if the number of the second content is less than 20, the second content is requested to be obtained from the network database D3 so as to meet the preset threshold of the second content, a first sequence is formed, and the target sequence is determined according to the first sequence. And after the target sequence is determined, sending the target sequence to the first terminal. And the first terminal sends a third operation instruction to the screen projection end after receiving the target sequence so as to play the target content selected by the user from the target sequence at the screen projection end.
Referring to fig. 4, the step of determining a target sequence according to the first sequence includes:
step S231, obtaining a second parameter set corresponding to each second content in the first sequence, where the second parameter set is a parameter set reflecting content quality;
step S232, determining the target sequence according to the second parameter set corresponding to each second content in the first sequence.
After determining the first sequence, a target sequence is further obtained according to the first sequence. The corresponding second parameter set of each second content in the first sequence may be obtained, so as to determine the target sequence. In this embodiment, the second content in the first sequence, in which the resolution is greater than the preset resolution and the color depth is greater than the preset color depth, is obtained in a form based on the second parameter. And forming a third sequence by the second content, and taking the third sequence as a target sequence with target content.
Optionally, in this embodiment, determining the target sequence may be performed by intercepting the first N second contents of the first sequence, and taking a sequence formed by the first N second contents as the target sequence. The method comprises the steps of obtaining a first content picture displayed at a screen projection end at present, cutting the first content picture based on the picture size, dividing the first content picture into A parts, obtaining second content corresponding to parts (face, hair style and makeup) similar to the first content picture in a first sequence based on each divided picture, comparing each second content with the picture of the first content, obtaining second content with higher similarity, and further obtaining a target sequence.
In this embodiment, the acquired content is further optimized by filtering the acquired content of the first sequence, so as to ensure that the target content determined to exist after the processing is the optimal content capable of replacing the first content.
Referring to fig. 5, fig. 5 shows a further embodiment of the present application, wherein the second parameter sets are resolution and color depth parameter sets, and the step of determining the target sequence according to the second parameter set corresponding to each of the second contents in the first sequence comprises:
step S2321, intercepting the first N second contents of the first sequence to obtain a second sequence;
step S2322, a resolution corresponding to each second content in the first sequence is obtained, the plurality of second contents in the first sequence are sequenced according to the order of the resolutions corresponding to the second contents, and the first K second contents are intercepted to obtain a third sequence;
step S2323, obtaining a color depth corresponding to each second content in the first sequence, sorting the plurality of second contents in the plurality of first sequences according to a sequence of the color depths corresponding to the plurality of second contents, and intercepting the first L second contents to obtain a fourth sequence;
step S2324, acquiring the second content in the second sequence, the third sequence and the fourth sequence, and taking a sequence formed by the second content in the second sequence, the third sequence and the fourth sequence as the target sequence.
In this embodiment, the similarity of each second content in the first sequence (a specific parameter or a combination of parameters of the first parameter set) is compared with the similarity of each second content in the first sequence displayed on the screen projection end, so as to obtain the first N second contents with higher similarity, where the first N second contents form the second sequence.
It can be understood that, in this embodiment, the resolution of each second content in the first sequence is obtained, the second contents are sorted according to the order of the resolution, and then K second contents before sorting are obtained to obtain a third sequence, where the value of K may be set by a system or a user.
Further, the color depth corresponding to each second content is obtained in the first sequence, sorting is performed according to the color depth, and the second content with higher color depth is screened to form a third sequence. Optionally, when the first sequence includes more second contents, the color depth of each of the second contents in the first sequence may be compared with the color depth of the current screen-projection-end first content image, and the second contents in the first sequence whose color depth is greater than the color depth of the current first content image are screened to obtain a fourth sequence.
The first sequence obtained in the present application is subjected to screening processing through a first parameter set, resolution and color depth, so as to obtain a second sequence, a third sequence and a fourth sequence. And further obtaining a common part of the second content contained in the second sequence, the third sequence and the fourth sequence, and determining the common part as a target sequence needing to be acquired. Optionally, in this application, the target sequence may be further sorted by obtaining a payment required for viewing each second content, and in a case that the quality dimension of the second content in the target sequence is higher than that of the first content, the second content with lower payment is preferentially sorted in the target sequence.
Specifically, in the process of determining the target sequence in this embodiment, the first terminal may be a mobile phone, and the screen projection terminal may be a television, for example, as follows: the mobile phone is connected with the television through the local area network and sends a picture of the piglet photo to the television, the television searches in the local database D1 through the search module according to the first parameter set of the picture of the piglet photo to obtain a first sequence, and the first sequence can be understood as a sequence formed by a plurality of second contents preliminarily acquired based on the first parameter set of the first contents. At this time, the similarity between all the second contents and the first contents (i.e. the similarity between each picture included in the second sequence and the currently released piglet photo in the television) can be compared in the first sequence, and the second sequence is obtained by cutting out the first N pictures.
