Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived from the embodiments of the present invention by those skilled in the art based on the description, are within the scope of the present invention.
Fig. 2 is a flowchart of a video split-screen display method provided in an embodiment of the present invention, where the method is applied to a play controller in a vehicle-mounted video playing system, where the vehicle-mounted video playing system further includes a plurality of target display screens, and as shown in fig. 2, the method includes the following steps:
In the embodiment of the invention, the original video comprises a plurality of picture frames, and each picture frame is formed by splicing a plurality of different picture windows. For example, fig. 3 is a picture frame in the original video, and as shown in fig. 3, picture frame 310 of the original video in fig. 3 is formed by splicing picture window 301, picture window 302, picture window 303, and picture window 304. For another example, fig. 4 shows a frame in an original video of a multi-people live broadcast category, and as shown in fig. 4, a frame 410 of the original video in fig. 4 is formed by splicing a frame window 401 and a frame window 402.
In the embodiment of the invention, each split picture window can be classified according to the area where the picture window is located relative to the spliced boundary in the picture frame of the original video; for each type of picture window, determining each picture window belonging to the type as a split video according to the time stamp sequence of the picture window; wherein, each picture window with the relatively spliced boundary in the same region in each picture frame of the original video is the same type of picture window; the time stamp of each picture frame of the original video is the same as the time stamp of each picture window spliced to form the picture frame.
For example, fig. 5 is a schematic diagram of two picture frames of the same original video, and as shown in fig. 5, the picture frame 510 and the picture frame 520 are two picture frames in the same original video X; and the picture frame 510 has a time stamp of t 510 The time stamp of the picture frame 520 is t 520 . The image frame 510 is split into the image window 501 and the image window 502, and the time stamps of the split image window 501 and the split image window 502 are also t 510 (ii) a Splitting the picture frame 520 can split the picture window 503 and the picture window 504, and the time stamps of the split picture window 503 and the split picture window 504 are also t 520 . As shown in fig. 5, the area of the picture window 501 in the picture frame 510 corresponds to the area of the picture window 503 in the picture frame 520, so that the split picture window 501 and the split picture window 503 belong to the same type of picture window; similarly, the area of the picture window 502 in the picture frame 510 corresponds to the area of the picture window 504 in the picture frame 520, and therefore, the split picture window 502 and the split picture window 504 belong to the same type of picture window. For each type of picture window, each picture window belonging to the type may be determined as a split video according to the sequence of the timestamps of the picture windows, for example, for the type of picture windows including the picture window 501 and the picture window 503, each picture window may be sorted according to the sequence of the timestamps of each picture window in the type of picture window (for example, the picture windows may be sorted according to the timestamp t of the picture window 501 510 And a time stamp t of the picture window 503 520 The image windows 501 and 503 are sequenced in order), each sequenced image window forms a split video, and the split video can be used as a split video corresponding to the image window. As shown in fig. 5, two split videos may be determined.
And step 204, displaying each split video on different target display screens.
For example, fig. 6 is a schematic diagram of a split video displayed on different target display screens. As shown in fig. 6, an original video 601 may be split into: split video 602 and split video 603. And, the split video 602 and the split video 603 are respectively displayed on different target display screens.
In the embodiment of the invention, the vehicle-mounted video playing system can further comprise a screen splitter.
In the embodiment of the invention, before each split video is displayed on different target display screens, the identifier of each target display screen can be obtained; specifically, in this step, identifiers may be allocated to the split videos according to the identifiers of the target display screens; and then, each split video is sent to a screen splitter, and each split video can be sent to a target display screen with the same identification for display by the screen splitter.
For example, fig. 7 is a structural diagram of an in-vehicle video playing system. Referring to fig. 7, if the identifications of the target display screen 1, the target display screen 2 and the target display screen 3 are "xsp1", "xsp2" and "xsp3", respectively, the identifications "xsp1", "xsp2" and "xsp3" of the target display screen 1, the target display screen 2 and the target display screen 3 may be transmitted to the play controller. The play controller may allocate an identifier to the split video 1, the split video 2, and the split video 3 according to the identifiers "xsp1", "xsp2", and "xsp3", for example, may allocate an identifier "xsp1" to the split video 1, allocate an identifier "xsp2" to the split video 2, and allocate an identifier "xsp3" to the split video 3. Then the playing controller can send the split video 1, the split video 2 and the split video 3 to the screen splitter, the screen splitter can send each split video to the target display screen consistent with the identifier of the split video for displaying, as shown in fig. 7, the screen splitter can send the split video 1 with the identifier of 'xsp 1' to the target display screen 1 consistent with the identifier of the split video for displaying, and similarly, the split video 2 can be sent to the target display screen 2 consistent with the identifier of the split video for displaying, and the split video 3 is sent to the target display screen 3 consistent with the identifier of the split video for displaying.
In the embodiment of the present invention, the split video is specifically displayed on the target display screen in the following manner a or manner B:
mode A: the picture proportion of each split video is a first picture proportion; if the screen proportion of each target display screen corresponding to each split video is the first screen proportion, each split video can be displayed in each target display screen according to a display mode (for example, a 16; or, displaying each split video in each target display screen according to a display mode (for example, a display mode of 16; or, performing full-screen display on each split video in each target display screen (for example, a 16.
The first picture proportion is the aspect ratio of the picture, and the first screen proportion is the aspect ratio of the screen; the first picture scale is smaller than the first screen scale, e.g., the first picture scale may be 4.
Mode B: the picture proportion of each split video is a second picture proportion; if the screen proportion of each target display screen corresponding to each split video is the second screen proportion, each split video can be displayed in each target display screen according to a display mode (for example, a display mode of 4; or, displaying each split video in each target display screen according to a display mode (for example, a display mode of 4; or, performing full-screen display on each split video in each target display screen (for example, the full-screen display mode may be 4.
The second picture proportion is the aspect ratio of the picture, and the second screen proportion is the aspect ratio of the screen; the second picture scale is larger than the first screen scale, for example, the second picture scale may be 16.
By adopting the method provided by the embodiment of the invention, the original video is obtained; splitting each picture frame of the original video based on the splicing boundaries of different picture windows in the picture frames, and splitting each picture window from each picture frame of the original video; determining a plurality of split videos based on the split picture windows; and displaying each split video on different target display screens. The split videos obtained based on the original video are displayed on different display screens, so that the problem of mutual interference generated by a plurality of windows in the picture of the same original video is avoided, and the use experience of watching the videos by a user is improved. And moreover, the accuracy of splitting each picture window from each picture frame of the original video is also ensured by judging whether the picture dividing line is coincident with the splicing boundary.
Fig. 8 is a flow of splitting an original video frame, and as shown in fig. 8, in a possible implementation, the splitting, in step 202, is performed on each picture frame of the original video based on a boundary of splicing different picture windows in the picture frame, which may specifically include:
And step 803, splitting each picture frame of the original video according to the picture splitting lines.
For example, referring to fig. 9, fig. 9 shows a picture frame obtained from an original video, and the picture frame is formed by splicing a picture window 910 and a picture window 920. Each picture frame of the original video may be split according to the picture splitting line 901 by performing image recognition on the picture frame, recognizing a boundary where the picture window 910 and the picture window 920 are spliced, and then generating a corresponding picture splitting line 901 based on the recognized boundary. In this step, the frame dividing line 901 generated for the original video and the source identifier of the original video may be correspondingly stored in the play controller.
Fig. 10 is another flow of splitting an original video picture frame, as shown in fig. 10, in a possible embodiment, the splitting, in the step 202, for each picture frame of the original video based on a boundary of splicing different picture windows may specifically include:
And step 1003, if yes, splitting each picture frame of the original video according to the picture splitting line.
The source identifier of the original video may be a source device identifier, for example, an device identifier of a video source device storing the original video, and specifically, the source identifier of the original video may be provided by EDID (Extended Display Identification Data): the EDID provides manufacturer information and/or brand code information and/or product serial number information of a video source device storing the original video to the play controller through an interface connecting the original video input/output as a source identifier that can identify the original video.
For example, if the product serial number information of the video source device storing the original video, which is provided by the EDID to the play controller, is "xyz", the source identifier of the original video may be obtained as "xyz", and then, whether a correspondingly stored picture dividing line for the original video exists may be found in the play controller according to the source identifier "xyz", and if the correspondingly stored picture dividing line α is found, each picture frame of the original video may be divided according to the picture dividing line α.
The source identification of the original video may also be a unique tag assigned to the original video that characterizes the source of the original video.
In a possible implementation manner, before splitting each picture frame of the original video according to the picture dividing line, whether the picture dividing line is overlapped with the splicing boundary of each different picture window in any picture frame of the original video or not can be judged; if not, the picture dividing line can be adjusted, so that the adjusted picture dividing line can be overlapped with the splicing boundary of different picture windows in any picture frame of the original video.
For example, referring to fig. 9, it may be determined manually whether the picture dividing line 901 coincides with a splicing boundary between the picture window content 910 and the picture window content 920 in the picture of the original video, and if the picture dividing line 901 coincides with the splicing boundary, each picture frame of the original video may be split according to the picture dividing line 901; if not, the position of picture split line 901 can be adjusted so that the adjusted picture split line can coincide with the border where picture window content 910 and picture window content 920 in the original video are spliced.
Referring to fig. 11, fig. 11 is a view of an in-vehicle video playing system according to an embodiment of the present invention, including: a play controller 1101 and a plurality of target display screens 1102;
the play controller 1101 is configured to obtain an original video, where the original video includes a plurality of picture frames, and each picture frame is formed by splicing a plurality of different picture windows; splitting each picture frame of the original video based on the splicing boundaries of different picture windows in the picture frames, and splitting each picture window from each picture frame of the original video; determining a plurality of split videos based on the split picture windows;
the play controller 1101 is further configured to send each split video to a different target display screen 1102;
