Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Currently, existing director system includes full-automatic and manual two kinds.Wherein, full-automatic director system is fixed by tracking
Position technology carries out camera lens movement and switching along with certain switchover policy.However, being currently applied to full-automatic director system
Tracking and positioning technology, such as infrared, laser positioning and video plus audio frequency tracking and positioning etc., are all highly prone to ring without exception
Border influences, especially for current various forms of classrooms and activity, such as grouping discussion type, various laboratories, reversion classroom
Complicated classroom form, may directly result in the collapse of full-automatic director system tracing-positioning system.Current full-automatic instructor in broadcasting
The original judgment methods such as whether instructor in broadcasting's strategy of system can only stand up according to people, whether where more, people walks about, completely not
Instructor in broadcasting's switching can be carried out according to actual activity content, the facial expression of people and on-site situation development etc., instructor in broadcasting's quality can not allow
People is satisfied.Thus to the higher important events of instructor in broadcasting's quality requirement, commonly used manual director system.But manual instructor in broadcasting
The equipment of system and manipulation are all complex, it is necessary to carry out instructor in broadcasting's manipulation by professional.And it is directed to general school and public affairs
The applications such as department do not have a large amount of professional instructor in broadcasting personnel offers of outfit and lead although having large-scale instructor in broadcasting's demand
The condition for broadcasting manipulation service, results in can not promoting the use of for manual director system.
It is led in view of the above-mentioned problems, the utility model embodiment proposes a kind of reduce while keeping higher instructor in broadcasting's quality

In order to better understand with application the utility model proposes a kind of director system and live streaming recording and broadcasting system, it is practical
Novel carry out following example, and the utility model is not only limited to following example.
Example one:
It is broadcast live in recording and broadcasting system, remote control equipment is the remote controler including at least three keys, and three keys are video respectively
Switching key, scene selection key and picture confirm key, and wherein video switching key corresponds to the video switching list of remote control equipment
Member, scene selection key correspond to the scene selecting unit of remote control equipment, and picture confirmation key corresponds to the recording elements of remote control equipment.
After entering network instructor in broadcasting, the video of instructor in broadcasting's picture can be switched by using the video switching key of remote controler
Source.When needing shooting of the quick calling camera preset seat in the plane to realize default scene, user can be cut using video first
It changes key and selectes camera views, subsequent usage scenario selection key is switched fast camera preset seat in the plane.If passing through video
Switching key selectes courseware and shows equipment, then can select different coursewares by scene selection key, such as notebook
The courseware that courseware or smart phone are shown by wirelessly throwing screen.
When being recorded, the video selection key on remote controler is clicked, the yellow frame in instructor in broadcasting's monitor is moved to
" beginning " clicks picture and confirms key, and into recording state, there is red icon flashing on instructor in broadcasting's monitor upper left side, and characterization is
It records.In this case, the video selection key on remote controler is clicked, the yellow frame in instructor in broadcasting's monitor is moved to " pause ",
Picture confirmation key is again tapped on, is selected " pause ", is interrupted and record.Similarly, " continuation " operation and " stopping " being carried out to recording
Operation.
This example greatly simplifies profession originally and complicated operation, and only needs three keys on remote controler can be complete
Recorded broadcast operation is broadcast live at whole instructors in broadcasting, so that a large amount of classroom or activity can be used for be broadcast live or record into resource at any time standby
With.Due to the simplification of operation, the people of the people that will be videoed and shooting is combined into one, it is movable due to attending class or presiding over
People is also simultaneously photographer, so that naturally combine together in shooting process, classroom or movable excellent place in content level
Host or speaker oneself become apparent from, and when need to shoot that camera lens also becomes apparent from oneself, simple remote controler behaviour
Make realization instructor in broadcasting, not only will not influence the speech process of speaker, additionally it is possible to dramatically improve instructor in broadcasting's mass, solve master
Say the waste of the time cost as caused by largely exchanging between people and instructor in broadcasting staff.
Example two:
Fig. 4 is a kind of live streaming recording and broadcasting system structural schematic diagram of the utility model embodiment, as shown in figure 4, live streaming recorded broadcast
System includes director system, streaming media server 202, cloud platform 405, local recording arrangement 203 and storage equipment 406.Wherein,
