fig. 2 is a flowchart of a second embodiment of a method for interactive operation of screen projection to a large-screen terminal according to the present invention.
Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
Example 1:
as shown in fig. 1, a method for performing screen-casting interactive operation on a large-screen terminal includes a user terminal, a screen-casting display terminal and a server, where the user terminal, the screen-casting display terminal and the server perform interactive operation according to the following steps:
firstly, a user terminal sends screen projection parameters to a screen projection display terminal; the screen projection display end analyzes the screen projection parameters and sends a screen projection request to the server end according to the analysis result; and the server controls the screen projection display end to play the screen projection content according to the screen projection request, and returns a screen projection result to the user terminal.
The user terminal can be a mobile phone, a tablet or a notebook, and the like, and corresponding screen projection software needs to be installed on the user terminal.
The screen projection parameters comprise content information and user information corresponding to the screen projection content.
If the screen projection content contains video content, the content information should include a video address and video parameters corresponding to the video content, the video parameters include the size, resolution, whether the video is legal or not and the like, the user information includes a user ID for identifying the user, and the server returns the screen projection result to the user terminal corresponding to the user ID when returning the screen projection result to the user terminal.
The user ID is a user virtual ID, so that the user privacy can be protected when the user terminal transmits and exchanges information with the screen projection display terminal and the server.
When the user terminal sends the screen projection parameters to the screen projection display terminal, the screen projection parameters can be sent through a remote controller or a voice control method displayed on the user terminal.
Example 2:
the difference between this embodiment and embodiment 1 is that the screen projection display end specifically includes, in analyzing the screen projection parameters: and judging whether the video content is a vertical screen or a horizontal screen according to the video parameters.
(1) If the video content is the horizontal screen content, the screen projection display end normally plays the screen projection content and returns a screen projection result to the user terminal;
(2) if the video content is vertical screen content, when the screen projection display end sends a screen projection request to the server end, the server end needs to judge whether the screen projection content contains advertisement content;
(21) the server analyzes the screen projection request to judge that the screen projection content contains the advertisement content, and then the server displays the corresponding advertisement content to the left side and the right side of the video of the screen projection display end;
(22) if the screen-casting content has no advertisement content, judging whether the screen-casting content has recommended content, if so, analyzing the recommended content, displaying the recommended content on the left side and the right side (vertical screen video) of the vertical screen video of the screen-casting display end, and if not, directly returning a screen-casting result to the user terminal.
It should be noted that, the server analyzes the screen projection parameters and determines whether the video content is supported by the screen projection display terminal and whether the source of the video content is a partner of the server according to the video parameters.
Specifically, the video content needs to be displayed on the screen projection display end and provided with screen projection service components corresponding to videos, such as DLNA, miracast, AirPlay and the like, and whether the video content is authorized to be played or not is judged at the same time.
For advertising content, it may be a static or dynamic picture, and the words "advertisement" or "promotion" are legitimately displayed on the advertising content. The user terminal may approve/disapprove the displayed advertisement contents or select the next advertisement contents.
For the recommended content, the recommended content should also be legally obtained from a partner of the server, when the video content is vertical screen content, the left and right sides of the video show the static or dynamic cover page images of the previous/next video program related to the current video content and the user information, and the video content corresponding to the next static or dynamic cover page image is automatically played or the video content corresponding to the previous/next static or dynamic image is played through the user terminal after the current video content is played, and similarly, the user terminal can also approve/cancel the approval of the current video content.
It should be noted that, a conventional algorithm for providing relevant recommended video according to the current video content and user information (such as a location, a browsing history, and the like) belongs to the current internet big data, and details are not repeated here.
When the screen projection display terminal starts to play a next selected video program, the screen projection parameters can load the information of the video program, and then the user terminal, the screen projection display terminal and the server interact the video content according to the same method.
