Preferably, described viewpoint data capture unit, what comprise in following subelement is one or more,

Viewpoint mover unit, carries out the movement of upper and lower, left and right and rotation to viewpoint, the angle of described dragging is 0-30 degree;

Any viewpoint selection subelement, selects position to display arbitrarily;

Seat in the plane viewpoint selection subelement, chooses the seat in the plane of panoramic video;

Touch gestures recognin unit, according to gesture on the touchscreen, identifies various viewpoint selection request.

Preferably, panorama display unit, also comprises, video buffer subelement, the video that disposable whole buffering is all, or according to selected viewpoint, the full screen video data that only the selected viewpoint of buffering is corresponding.

And/or also comprise, definition chooser unit, for switching the definition of SD, high definition, super clear, 1080P.

Method and system of the present invention may be used for the player for showing panoramic video in mobile terminal, thus the experience sense of adding users.Viewpoint selection variation, user can specify arbitrary viewpoint, to obtain the required video appreciated, provides recommendation viewpoint simultaneously.There is viewpoint seat in the plane, with the viewpoint required for obtaining rapidly in live, provide simultaneously and recommend seat in the plane viewpoint, achieve the optimization appreciated angle and seat in the plane and switch fast.

Accompanying drawing explanation

Fig. 1 is the method for display panoramic video according to a particular embodiment of the invention;

Fig. 2 is the system of display panoramic video according to a particular embodiment of the invention.

Embodiment

Below in conjunction with drawings and Examples, the present invention is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, illustrate only part related to the present invention in accompanying drawing but not entire infrastructure.

See Fig. 1, show the method for display panoramic video according to a particular embodiment of the invention, comprise the steps:

S110: read panoramic video data;

S120: obtain viewpoint data;

S130: the panoramic video playing up corresponding viewpoint according to described viewpoint;

S140: broadcast described panoramic video.

Therefore, the present invention, from server, obtain panoramic video resource play in the player of client, in panoramic video resource, the size of each two field picture is all greater than the display size of player window, that is, the current picture that user sees in player window is a part for panoramic video current frame image.Therefore, viewpoint data must be obtained, and then obtain corresponding panoramic video according to described viewpoint, finally for playing.

Preferably, described viewpoint comprises default viewpoint and/or recommends viewpoint, and described default viewpoint is the middle part of panoramic video two field picture, and described recommendation viewpoint is adopt the mode of recommending to show to comprise the abundantest position of video content.The abundantest position of this video content can be calculated by large data algorithm.Certainly, in the present invention, the viewpoint that described default viewpoint also can be watched for last video, or the viewpoint that user specifies arbitrarily.

Further preferably, in acquisition viewpoint data step, can move viewpoint, comprise the movement of upper and lower, left and right and rotation, the angle of described movement is 0-30 degree, further preferably, the angle of described movement is 0-360 degree, thus carries out omnibearing movement.

Further preferably, in acquisition viewpoint data step, the selection of any viewpoint can be carried out, adopt the mode of similar electronic chart, select position to display arbitrarily.

Further preferably, in acquisition viewpoint data step, can seat in the plane viewpoint selection be carried out, the seat in the plane of panoramic video can be chosen.Such as adopt numeral to carry out serial number to several conventional viewpoint, and store using as seat in the plane, so that select.Such as, for live, as: football match, user can formulate corresponding seat in the plane in advance according to the position of ball in court, when watching panoramic video, carries out the switching of different seat in the plane rapidly, provides other seats in the plane to select for user simultaneously.Meanwhile, in the present invention, also can obtain recommending seat in the plane viewpoint by algorithm.

Further preferably, in acquisition viewpoint data step, touch gestures recognin step can also be carried out, according to gesture on the touchscreen, identify various viewpoint selection request.Such as, the upper and lower, left and right of viewpoint and rotation, the mitigation and amplification of video.

In the described panoramic video step S140 of broadcast, in order to accelerate the broadcasting of video, also there is video buffer sub-step, can all video of disposable whole buffering, namely the panoramic video that disposable download is all, to watch panoramic video in time, or according to selected viewpoint, the full screen video data that only the selected viewpoint of buffering is corresponding, to improve the fluency of display in the slack situation of user network.Only have and drag behavior when user has carried out picture, in other words, when viewpoint changes, just cushion the part that will show.

Preferably, in the described panoramic video step of broadcast, also there is definition chooser step, for switching the definition of SD, high definition, super clear, 1080P.

Above-mentioned panoramic video display packing may be used for the player for showing panoramic video in mobile terminal, thus the experience sense of adding users.Viewpoint selection variation, user can specify arbitrary viewpoint, to obtain the required video appreciated, provides recommendation viewpoint simultaneously.There is viewpoint seat in the plane, with the viewpoint required for obtaining rapidly in live, provide simultaneously and recommend seat in the plane viewpoint, achieve the optimization appreciated angle and seat in the plane and switch fast.

Further, the invention also discloses a kind of system showing panoramic video, comprise as lower unit:

Panoramic video data-reading unit 210: for reading panoramic video data;

Viewpoint data capture unit 220: for obtaining viewpoint data;
