In the panoramic video playing process, if the situation that the user selects any recommended visual angle corresponding to any video playing time is detected, returning the video playing time selected by the user again, and switching to the recommended visual angle selected by the user for playing.
In addition, in the invention, an option of 'automatic playing' and 'manual playing' can be added in the panoramic video playing control menu, if the user selects 'automatic playing' before or during playing, then for any video playing time with a recommended viewing angle, if the video playing time corresponds to a plurality of recommended viewing angles, the video playing time is played according to the corresponding first recommended viewing angle by default. If the user selects 'manual playing' before or in the playing process, then for any video playing time with a recommended visual angle, displaying the recommended visual angle corresponding to the video playing time to the user, and playing according to the recommended visual angle selected by the user.
In addition, when the recommended viewing angle corresponding to a video playing time is displayed to the user, the identification information of each recommended viewing angle, such as: numbers 1, 2, …, etc. are displayed to the user for selection by the user; the preview screen of each recommended viewing angle can also be directly displayed, and the preview screen can contain a target area, so that the user can select the target area intuitively, for example: and displaying the thumbnail preview list of all the recommended view pictures.
In addition, for any video playing time, when the video playing time corresponds to the position information and the enhancement information of the target area, whether the target area is in the current playing picture is judged according to the position information of the target area, if so, the target area is found according to the position information of the target area, and then the enhancement display is carried out on the target area according to the enhancement information of the target area. If a message and a presenting method thereof for the target area exist, after the target area is subjected to enhanced display, the user can be inquired in a dialog box whether the message needs to be played, and if a positive response returned by the user is received, the message is played according to a set presenting method (such as a display box, voice, text and the like).

For example: attack and defense are carried out simultaneously in a shot war scene, a recommended visual angle can be preset through the method for controlling the playing of the panoramic video, and the corresponding relation between the preset video playing time and the recommended visual angle is assumed as follows:
video playing time: 00:01:00, recommended viewing angle: (100 ) (attack perspective), (300 ) (defense perspective);
video playing time: 00:03:00, recommended viewing angle: (200 );
……
wherein aa: bb: cc represents aa hour bb minute cc second, and the recommended viewing angle is represented by the center coordinates of the recommended screen.
Assuming that the user selects "manual play" mode, playing at the default view angle for 1 minute will prompt the user to recommend view angle 1: (100 ), recommended viewing angle 2: (300 ), if the user selects the recommended view angle 1, switching the current playing view angle to the recommended view angle 1: (100 ) playing;
from then on, with the recommended viewing angle 1: (100 ) playing, and when playing for 3 minutes, prompting a recommended viewing angle to a user: (200 ), if the user selects the recommended viewing angle, switching the current playing viewing angle to the recommended viewing angle: (200 ) playing;
from this point onwards, with the recommended viewing angle: (200 ) playing;
in addition, recommended viewing angles corresponding to all video playing times can be listed in the pull-down menu, so that a user can select any recommended viewing angle of any video playing time at any time to play, for example: when the playing time reaches 5 minutes, if the user selects the video playing time in the pull-down menu: recommended viewing angle of 00:01: 00: (300 ), searching the video playing time in the panoramic video file: recommended viewing angle of 00:01: 00: (300 ) switching the current playing picture to the searched picture for playing according to the corresponding pictures, and then continuously displaying the pictures at the recommended visual angle: (300 ) playing until the user selects another recommended perspective.
By way of example, it can be seen that: by presetting the recommended visual angle, the user can completely browse all interesting events.

At present, a user can browse scenic spots through VR videos without going out. The method for enhancing the target area can explain and explain key scenic spots, landmarks, gourmets and other contents in the video in detail and provide better experience and cognition for users by combining the best viewing angle.
Taking a panoramic video of a scenic spot as an example, recommended viewing angles of different playing times in the video are preset, an interested target area is set, and enhanced display setting is performed on the target area.
For example: video playing time: 00:30:00, recommended viewing angle: (100 ), target area center point: (50,30), target area size: (300,200), region enhancement mode: flashing target area and explaining with voice.
Assuming that the user selects automatic play, when the panoramic video is played for 30 seconds, switching to the recommended viewing angle: (100 ), simultaneously detecting whether the target area appears in the recommended visual angle in real time, if so, flashing the target area (50,30), (300,200) and inquiring whether the user needs to play the voice of the target area in a dialog box mode, and if the user selects 'yes', playing the voice to the user.
After finding that the target area flickers, the user can also actively request to play voice, and the active request mode is as follows: a screen pause operation or an interface control button or triggered by staying in the target area for a long time. In addition, when the video has audio, the playing of the video with audio can be temporarily set when the voice of the target area is played, so as to eliminate the sound interference.
As shown in fig. 3, there are two target areas in the drawing for enhanced display, and the left message in the target area is presented in text: "Heart nourishing palace" and "Qianlong ethnic palace".
Through the embodiment, the user can see the scene area picture and hear the scene area explanation, and the viewing experience is enhanced.
Example 3: fast browsing of video content
The quick browsing list can be generated by recommending the view angle.
One possible playing mode is to generate a shortcut entry of a recommended view of the target area by analyzing the target area information. The shortcut entry may be a thumbnail or may be presented in other forms. One possible form is to present a thumbnail list of the target area before the playing starts, and the user can choose to browse the thumbnail contents directly according to personal wishes or jump to the corresponding video screen directly through the thumbnail.
As shown in fig. 4, a list of thumbnails of recommended viewing angles of target areas is generated below the screen, and the target areas are, from left to right: the entrance vestibule, the living room, the secondary bedroom bathroom, the entrance secondary bedroom, the dining room, the kitchen, the bedroom corridor, the prince bedroom, the prince bathroom, the main bedroom, the prince bedroom and the prince bathroom, and the user can browse the corresponding video pictures by clicking the interested thumbnail.
Example 4: VR video advertisement content replacement
Taking a VR live-action house as an example, a soft-design brand may be recommended when a particular scene is viewed at a particular time. The recommendation information may include pictures or/and text. The recommendation information is used as a part of the enhancement information of the target area, and the replacement of the recommended advertisement content can be completed through simple information editing. For example: the target area is a curtain, the enhancement information is a picture path, and the picture content is introduced to a certain brand. When a new soft-assembly partner exists, only the picture needs to be replaced.
The invention has the following beneficial technical effects:
the corresponding relation between the video playing time and the recommended visual angle is set, and the panoramic video is played by switching to the recommended visual angle according to the corresponding relation when being played, so that wonderful content cannot be omitted, a plurality of events which occur at the same time can be played according to the selection of a user, the viewing experience is improved, the playing control of the panoramic video is more flexible, and the intention of an author is better presented.
