Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In order to make the technical solutions provided in the embodiments of the present application better understood and make the above objects, features and advantages of the embodiments of the present application more comprehensible, the technical solutions in the embodiments of the present application are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a flow chart of a recorded and broadcast video summary generating method provided in an embodiment of the present application is schematically shown, where the recorded and broadcast video summary generating method is applied to a recorded and broadcast host in a recorded and broadcast system, as shown in fig. 1, the recorded and broadcast video summary generating method may include:
and S100, acquiring a recorded and played video picture and a courseware picture.
In the embodiment of the application, the recorded broadcast host can acquire recorded broadcast video pictures (namely classroom video pictures) through the front-end camera and acquire courseware pictures through a computer for playing teaching courseware.
For example, a PC playing the teaching courseware may be connected to the recording and playing host computer through a VGA (Video Graphics Array) or HDMI (High Definition Multimedia Interface) line, and transmit the courseware image to the recording and playing host computer in real time.
It should be noted that, in this embodiment of the application, the recording and playing host may further obtain audio data of the teaching classroom through an audio device (such as a sound pickup) to be used for the recording and playing host to generate a recorded and played video, and specific implementation of the recording and playing host may refer to related implementation in an existing recording and playing system, which is not described herein again in this embodiment of the application.
And step S110, determining summary information according to the courseware picture.
In the embodiment of the application, after the recording and broadcasting host acquires the courseware picture, the summary information can be determined according to the acquired courseware picture.
In an embodiment of the application, the determining the summary information according to the courseware image may include:
when detecting that the courseware picture changes, capturing the courseware picture;
the captured image is identified to determine summary information.
In this embodiment, after the recording and broadcasting host acquires the courseware image, the courseware image may be detected to determine whether the courseware image changes.
Optionally, when the recording and broadcasting host detects that a pixel change occurs in the courseware image and the number or the proportion of the changed pixels exceeds a preset threshold, the recording and broadcasting host may determine that the courseware image changes.
In this embodiment, when the recording and broadcasting host detects that the courseware image changes, the recording and broadcasting host can capture the courseware image, identify the captured image, and determine the summary information according to the character information obtained by identification.
It should be noted that, in the embodiment of the present application, the recording and playing host may also determine the summary information directly by performing intelligent analysis on the courseware image, and the specific implementation thereof is not described herein again.
In one example, the recognizing the captured image to determine the summary information may include:
and identifying a preset area of the captured image to determine summary information.
In this example, considering that there may be more characters in the teaching courseware, if the snapshot of the whole courseware screen is directly identified, there are more characters to be identified, and if the identified characters are directly taken as the abstract, the abstract is too cumbersome, so an area (referred to as a preset area herein) for acquiring abstract information may be selected in advance in the courseware screen, so that the recording and broadcasting host may not need to identify the snapshot of the whole courseware screen, and the efficiency of determining the abstract information and the simplicity of the determined abstract information are improved.
Accordingly, in this example, after the recording and broadcasting host captures an image of the courseware picture, a preset area of the captured image may be identified to determine summary information.
For example, the courseware title area may be determined as a preset area, the recording and playing host computer may identify the courseware title area, and the identified characters (i.e., courseware title) may be used as summary information.
Further, in this example, in consideration of the fact that multiple consecutive pages of courseware may have the same title in the courseware, in this case, in order to avoid multiple consecutive identical summary information, after the recording and broadcasting host determines the summary information, the determined summary information may be compared with the summary information determined last time, and if the two are not identical, the determined summary information is saved; otherwise, the determined summary information is refused to be saved.
It should be noted that, in the embodiment of the present application, if the recording and playing host does not recognize the character when recognizing the preset area of the courseware screen capture, the recording and playing host may not generate new summary information.
It should be appreciated that, in the embodiment of the present application, the above-mentioned manner of determining the summary information by identifying the preset area of the screenshot of the courseware image is only a specific example of determining the summary information according to the courseware image in the embodiment of the present application, and is not limited to the protection scope of the present application, for example, the recording and playing host may also identify the screenshot of the whole courseware image, and use the top identified continuous character as the summary information, and the specific implementation thereof is not described herein again.
And step S120, generating the recorded and broadcast video comprising the summary information according to the recorded and broadcast video picture and the summary information.
In the embodiment of the application, after the recorded broadcast host determines the summary information, the recorded broadcast video including the summary information can be generated according to the acquired recorded broadcast video picture and the summary information.
In an embodiment of the present application, the generating a recorded broadcast video including summary information according to a recorded broadcast video frame and the summary information may include:
generating recorded and broadcast video according to the recorded and broadcast video picture;
and storing the recorded and broadcast video and the summary information in an associated manner.
In this embodiment, after the recorded broadcast host determines the summary information, the recorded broadcast video may be generated according to the recorded broadcast video frame, and the recorded broadcast video and the summary information may be stored in an associated manner.
For example, the recorded broadcast host can store the recorded broadcast video and the corresponding summary information in a continuous storage space; or, the recorded broadcast host may store the recorded broadcast video and the corresponding summary information in different storage spaces, and record an association relationship between a storage address of the recorded broadcast video and a storage address of the corresponding summary information.
It should be noted that, in the embodiment of the present application, the recorded broadcast host generates a recorded broadcast video and determines summary information, which may be performed concurrently; or, the recorded and broadcast video can be generated firstly, and then the summary information is determined; alternatively, the summary information may be determined first, and then the recorded and broadcast video is generated, which is not limited in the embodiment of the present application.
Further, in an embodiment of the present application, after the generating the recorded video including the summary information according to the recorded video picture and the summary information, the method may further include:
and when a playing instruction for the recorded and played video is received, displaying the summary information in a specified area of a playing interface of the recorded and played video.
In this embodiment, when the user plays the recorded and broadcast video, the recorded and broadcast host may obtain the summary information corresponding to the recorded and broadcast video, and display the summary information in the specified area of the playing interface of the recorded and broadcast video, and the specific implementation thereof will be described below with reference to specific examples, which are not described herein again in this embodiment of the present application.
In an example, after the summary information is presented in the designated area of the playing interface of the recorded and played video, the method may further include:
when a selection instruction for any abstract in the abstract information is received, playing a recorded and played video corresponding to the abstract; and the recorded and broadcast video corresponding to the abstract is the recorded and broadcast video of the time period corresponding to the abstract.
In this example, the user may view the recorded video segment of interest by selecting the summary from the summary information presented in the designated area of the playing interface of the recorded video.
Correspondingly, when the recording and broadcasting host receives a selection instruction for any abstract in the abstract information, the recording and broadcasting host can play the recording and broadcasting video in a time period corresponding to the abstract.
The time corresponding to the abstract is the system time when the recording and broadcasting host acquires the picture capture of the courseware picture of the abstract.
For example, if the recording and broadcasting host captures an image of a courseware image at time t1 and identifies a preset region of the captured image of the courseware image to obtain an abstract a, the time corresponding to the abstract a is t 1.
In order to enable those skilled in the art to better understand the technical solutions provided in the embodiments of the present application, the following describes the technical solutions provided in the embodiments of the present application with reference to specific application scenarios.
Referring to fig. 2, an architecture diagram of a specific application scenario provided in the embodiment of the present application is shown in fig. 2, where the application scenario may include a recording and playing host, a front-end camera (including a teacher trackball and a student trackball), a PC, a sound pickup, and a recording and playing video playing device (including a display and a projector).
Wherein:
the front-end machine is used for collecting classroom pictures;
the sound pick-up is used for acquiring audio data in recorded and played videos;
the PC is used for playing the teaching courseware and collecting courseware pictures;
the recorded broadcast host is used for generating and storing recorded broadcast videos;
the recorded and played video playing device is used for playing recorded and played video.
Based on the application scenario shown in fig. 2, in this embodiment, the implementation flow of the recorded and broadcast video summary generation scheme is as follows:
on the one hand, the recorded broadcast host acquires classroom pictures shot by the front-end camera in real time through the broadcast guide channel, acquires audio data in a classroom through the sound pick-up, and further generates recorded broadcast videos according to the acquired teacher pictures and the audio data.
The specific implementation of the recorded and broadcast video generated by the recorded and broadcast host can be referred to the related implementation in the existing recorded and broadcast system, and the details of the embodiment of the present application are not repeated herein.
On the other hand, after the signal of the PC is accessed, the teacher plays teaching courseware on the computer, and the signal is accessed to the recording and playing host computer through the VGA/HDMI line to form courseware signal video. The recording and broadcasting host detects the video picture of the courseware signal (namely the courseware picture) in real time and analyzes whether the courseware picture has change. When it is detected that the courseware image changes and reaches a certain threshold (that is, there is a pixel change, and the number or proportion of the pixel change exceeds a preset threshold), the recording and broadcasting host captures a picture from the courseware signal video, and then sends the picture and the recognition area information to the intelligent OCR analysis module to complete character recognition analysis, so as to obtain summary information, where a flow diagram may be as shown in fig. 3A.
In order to recognize and extract the summary information in the courseware signal video, it is first necessary to configure in the recording and broadcasting host which area of the courseware image the summary information is in, for example, a courseware title area can be used as a recognition area.
For example, taking the courseware shown in fig. 3B as an example, the courseware title area may be determined as the identification area, and after the recording and broadcasting host captures a picture from the courseware signal video, the picture and the coordinate information of the courseware title area may be sent to the intelligent OCR analysis module to complete character recognition analysis, so as to obtain summary information.
In this embodiment, the recording and playing host may store the content of the summary information and the time information (system time when capturing pictures) in association with the recording and playing video to the hard disk, so as to obtain the recording and playing video including the summary information, and a schematic diagram thereof may be as shown in fig. 3C.
The user can log in the recorded and broadcast host computer through the web, retrieve the recorded and broadcast video and the associated summary information thereof, and play the recorded and broadcast video including the summary information through the projector or the display.
The playing interface of the recorded and played video including the summary information may be as shown in fig. 3D, the playing interface of the recorded and played video including the summary information may include an area for displaying the summary information (which may be referred to as a summary displaying area, such as an area on the right side of the video player in fig. 3D); in addition, when the user views the video playing progress, the summary information corresponding to the recorded and played video in the time period can be displayed in the video progress display area in real time. Furthermore, the user can trigger the recorded and broadcast host to play the recorded and broadcast video corresponding to the selected summary information by clicking the summary information displayed in the summary display area or dragging the progress bar according to the summary information displayed in the video progress display area.
For example, a teacher uses PPT courseware on a history course on the recording and broadcasting system, and courseware subjects are Qin dynasty history, Han dynasty history, Su dynasty history, Tang dynasty history and the like respectively. At the moment, a student wants to see the inertial heading history explanation in the course, enters a web interface, sees the inertial heading history of the video abstract index, and then clicks the abstract, and the equipment is used for positioning and playing the inertial heading history explanation video corresponding to the abstract.
In summary, in this embodiment, the recorded broadcast video summary generation and the recorded broadcast video playing process may be as follows:
(1) and configuring a course summary information detection area (namely the identification area).
And a course summary information detection area is configured on the recording and broadcasting host computer to avoid the identification of non-summary information and excessive identification information.
