Step S110: use business object to throw in the screen arranged in template in the auditorium overlapped and throw in business object to be put, with while playing the real-time audio and video data of showing stadium, in the screen arranged in the auditorium of the stadium of broadcasting displaying, the broadcasting displaying of business object is carried out in position.
Wherein, the business object of input can be advertisement.The broadcasting of business object is shown can adopt static form broadcasting, such as: show the word corresponding to business object and/or image in the screen arranged in auditorium; Also dynamic form can be adopted to play, such as: the word corresponding to business object and/or image are play in screen with the form rotating animation.
Preferably, business object is thrown in template and is arranged screen when throwing in business object to be put, forms an overturn screen, also can be described as turnover panel with the formal expansion of audience wave.
Certain screen is not limited to when throwing in business object to be put and throws in business object with the form of overturn screen, those skilled in the art can be arranged input form according to the actual requirements, such as: with reference to the form of PPT projection, the input form of screen is set to the business object of throwing in the formal expansion of " shutter ", or directly represents the business object of input with the form of plane.
The method of the input business object provided by the present embodiment, while the real-time audio and video data playing competitive sports, play position in stadium auditorium throws in business object, input due to business object do not affect race playing progress rate, also can not take sports field, the expense of therefore throwing in business object is low therefore, it is possible to save publicity cost.In addition, the method of the input business object that the present embodiment provides, business object is be embedded in the audio, video data of broadcasting in real time when throwing in, spectators just can get the business object information of input while watching the match, neither affect that spectators watch the match, time also not outside occupying volume, this input mode is easily received, and the spectators come to matches can see the business object of input, therefore, there is good the effect of publicity.Visible, the method for the input business object that the present embodiment provides, the method for more existing input business object, had not only saved publicity cost but also the effect of publicity that can play.
Embodiment two
With reference to Fig. 2, show a kind of flow chart of steps of throwing in the method for business object according to the embodiment of the present invention two.
The concrete steps of throwing in the method for business object in the present embodiment comprise:
Step S202: jettison system, according to the demand of throwing in business object in the position, auditorium of stadium, obtains the business object corresponding to position, auditorium and throws in template.
Wherein, business object is thrown in the auditorium of the stadium in template and is provided with at least one screen; For the setting of screen number and size, can be arranged according to the actual requirements by those skilled in the art, such as: according to the length of auditorium arrange screen number, to throw in the area of auditorium in template according to business the screen that size is applicable to be set.Jettison system can be the work station in mobile control room.Information interaction is carried out between work station and the The Cloud Terrace controlling video camera in mobile control room.Such as: in mobile control room, work station can adjust the angle of video camera by The Cloud Terrace, and in mobile control room, work station can also receive the real-time audio and video data that video camera is uploaded.The audio, video data got can be relayed by the work station in mobile control room in the terminal such as TV, computer.
When throwing in business object, although be all throw in business object in auditorium, different position, auditorium correspondences has different business objects to throw in template.Such as: the auditorium in the audio, video data that video camera is recorded may be positioned at the corner of stadium, so recorded auditorium length is shorter, auditorium length in the corresponding business object corresponding with it input template is also shorter, the size of set screen and the limitation of number larger.Auditorium in the audio, video data that video camera is recorded may be also the auditorium of whole of stadium, so recorded auditorium length is then longer, the auditorium length that the corresponding business object corresponding with it is thrown in template is also longer, and the size of set screen and the degree of freedom of number just can be high.And, the width of the auditorium shown in the audio, video data recorded also is different, have may be one section of auditorium of amplifying and what have may be the one section of auditorium reduced, one section of its width of auditorium amplified is narrower than the width of the one section of auditorium reduced, visible, the position of the auditorium in the audio, video data of recording and size are different.The position of the auditorium in audio, video data is determined by the angle of the video camera of recording audio/video data and the camera lens depth of field.
The variation of the position of the auditorium in the audio, video data recorded determines the variation that business object throws in template.Certainly, also can there is corresponding relation in the input template of the angle of video camera, the depth of field of camera lens and business object.
Step S204: jettison system selects the video camera of the audio, video data recording position, auditorium.
The business object being previously stored with position, multiple auditorium in jettison system throws in template, and stores and throw in the adjustment parameter for adjusting video camera corresponding to template with each.
In the present embodiment, for the selection of video camera of audio, video data of recording position, auditorium, because business object well can not be shown in the auditorium in the stadium that the video camera of other seats in the plane is recorded.Therefore, select the video camera being positioned at main frame position to record the audio, video data of position, auditorium, no matter main frame position is the whole plane adopting large full shot or little full shot can be recorded to auditorium.
A kind of preferred selection mode is: the large full shot that selection main frame position also adopts is to record the audio, video data of the position, auditorium in stadium, one section of longer auditorium can be recorded by the large full shot in main frame position, corresponding business is thrown in the auditorium in template can arrange multiple screen simultaneously, throw in more business object by the multiple screens arranged simultaneously, and, the audio, video data that large full shot is recorded is switched often, correspondingly, business object is demonstrated to the number of times of spectators also just more, has better the effect of publicity.Certainly the video camera being positioned at seat in the plane, stadium side can also be selected to adopt large full shot to carry out recording audio/video data.
Step S206: jettison system obtains the adjustment parameter of the video camera selected, according to the angle of adjustment parameter adjustment video camera.
Wherein, adjust parameter to comprise: at least one group of parameter in the transducer delay parameter of video camera, seat in the plane parameter, camera lens basic parameter, rotating shaft parameter, anchor point parameter and zoom parameters.
When the transducer delay parameter adjustment video camera according to video camera, obtain the transducer delay parameter of video camera, according to the transducer of transducer delay parameter adjustment video camera, the real-time audio and video data that video camera is recorded are play after extending to the duration of transducer delay parameter instruction and are shown.Such as: delay parameter is adjusted to 85ms that is 85 milliseconds, by adjustment delay parameter can realize record audio, video data and stadium in real scene synchronous.
