Part relevant to related invention is illustrated only in description, attached drawing.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The numbers such as first, second hereinafter only distinguish, and have no other meanings.
Fig. 1 is the application system structural schematic diagram of recorded broadcast data provided by the invention, as shown in Figure 1, the recorded broadcast data
Application system includes: recorded broadcast platform 101, first network equipment 102, second network equipment 103, first server 104 and second
Server 105.
Recorded broadcast platform 101 is arranged in each educational institution in multiple educational institutions of first area, every for receiving
In a educational institution, audio-frequency information, at least one video acquisition of at least one audio collecting device acquisition in each classroom are set
The video information of standby acquisition and the courseware-related information of classroom terminal device；Then keyword extraction is carried out to the audio-frequency information, and obtained
The time location information for extracting keyword is taken, and according to time location information, the first keyword is labeled in video information, is connect
Integration processing carried out to the video information, audio-frequency information and the courseware-related information that are labelled with the first keyword, generate files in stream media.
Specifically, first area can be some area in some city, for example, Changping District, Beijing, educational institution be can be
School, school can be senior middle school, be also possible to vocational school, can also be primary school etc., the application does not limit this.
In each classroom of each school, audio frequency apparatus and video equipment can be set.For example, there are 12 religions in A school
Room, number are followed successively by classroom 1 to classroom 12, and multiple audio collecting devices have can be set in each classroom and multiple video acquisitions are set
It is standby, for example, have 4 video equipments and 4 audio frequency apparatuses, video equipment 1 can be followed successively by video equipment 4, audio frequency apparatus 1 to
Audio frequency apparatus 4, each video equipment can be set in different orientation, and similarly, each first video equipment also can be set
Different orientation.As a result, by acquiring the audio/video information of the same scene of giving lessons in same classroom from each different orientation, guarantee
