Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for converting a live video into a fragmented video on demand according to an embodiment of the present invention, where the embodiment is applicable to a situation where a live video starts to perform a fragmented video on demand on a video content that has already been played, and the method can be executed by a device for converting a live video into a fragmented video on demand. The method specifically comprises the following steps:
and step 110, synchronously recording the live video which is currently live.
In a specific embodiment of the present invention, live video may include live television and live webcast. Live television broadcasting comprises live broadcasting and recorded live broadcasting, wherein the live broadcasting refers to real-time video signal acquisition and audio signal acquisition on activities in the process of live broadcasting, and is transmitted to terminal equipment such as a television and the like at a user end in real time in a microwave signal form after the signals are quickly processed, such as a live broadcasting evening party or a sports event and the like; the recorded live broadcast refers to a live broadcast that can be performed only by a television station with a copyright for videos such as a manufactured program or a television play, for example, each television station has a corresponding video broadcast at a specific time every day. The live television can be transmitted to a designated website through a network, and live broadcast is carried out in real time in a live network broadcast mode. Meanwhile, the network live broadcast at least also comprises a video live broadcast which is only live broadcast on a network platform, such as a video live broadcast of a network play or a personal live broadcast. It is understood that the live video in the embodiment of the present invention refers to a video that is played in a television or a network for the first time, and therefore, only the relevant producer or copyright holder of the video owns the corresponding video file before the video is played.
In this embodiment, since the live video is still in the middle of live broadcasting, there is no video file corresponding to the part of the live video that has been broadcast in the television or the network at this time. In general, video resources of corresponding videos only exist in the network when live broadcasting is finished or after the zero point of the day when live broadcasting is finished. Therefore, when the live video starts to be played directly, the live video is synchronously recorded, and the recorded video file corresponding to the live video of the on-demand service is obtained in real time. In this embodiment, the synchronous recording mode of the live video is not limited, and at least the synchronous recording of the live video by using screen recording software is included.
Illustratively, when providing real-time fragmented on-demand services for live video, the live time of the live video is generally known in advance. Therefore, when the live video starts to be played directly, the synchronous recording of the live video is started, and the recorded video file corresponding to the video content of the live video which is already played can be obtained in real time. For example, if the news simulcast starts to be live at 19:00 on time, synchronous recording of the news simulcast is started at 19:00 on time or in advance, and a recorded video file corresponding to video content already broadcasted by the news simulcast can be obtained in real time. For example, when a news simulcast is live for 3 minutes, a recording video file corresponding to the time point from when recording is started to 19:03 may be obtained at this time.
And 120, according to the broadcast content of the live video, performing real-time strip splitting processing on the live video to obtain a fragmented video of the live video.
Specifically, the stripping refers to dividing a continuous video stream into video segments with specific semantics by using a video segmentation technology. In a specific embodiment of the present invention, in order to obtain fragmented videos corresponding to one or more video segments in a live video at a first time when a complete video segment with one or more specific semantics in the live video ends, the present embodiment may monitor and browse the content of the live video that is being played in real time, and according to the content of the live video that is being played, when a certain video segment with specific semantics in the live video is played completely, in a recording file of a live video that is synchronously recorded and recorded, a start position and an end position of the video segment are dotted, that is, timestamps are respectively established at the start position and the end position of the video segment. Or extracting the voice audio and/or video pictures of the live video in real time, processing the voice audio and/or video pictures in real time by adopting advanced technologies such as a lens detection technology, an audio fingerprint technology, a video database organization and index technology, a video retrieval technology based on motion characteristics, query-oriented characteristic extraction and matching and the like, and automatically dotting and stripping the live video by synthesizing a real-time processing result so as to obtain fragmentation processing corresponding to a part of the live video which is already played in real time.
Illustratively, for a news program being live, such as a news simulcast, according to the broadcast content of the news, when the first news broadcast is finished, the first news is stripped within the first time, so as to obtain a fragmented video corresponding to the first news in real time. Or, the mouth broadcasting voice of the broadcaster is extracted in real time, semantic analysis is carried out on the voice, the playing of the first news is judged to be finished according to the semantic analysis result, and then the first news is stripped in the first time. For example, when the mouth-broadcast voice of the broadcaster is "please see next news" next, the first news is determined to be played over according to semantic analysis or keyword matching, and the recorded video file is further processed by dotting and splitting. By analogy, fragmented videos corresponding to each piece of news of the news simulcast can be obtained in real time respectively.
Preferably, matching the broadcast content of the live broadcast video with a pre-established advertisement library in real time, and determining advertisement segments inserted in the live broadcast video; and segmenting and deleting the advertisement segments.
In the embodiment of the invention, even if the video is live, the video also contains additional information such as advertisements. For example, during the midfield rest period of a live sports event, additional advertising information is added via video rebroadcast of a television station, or the live program itself adds additional advertising information for advertising. In this embodiment, since the number of the advertisements is limited, by creating an advertisement library containing almost all the advertisements in advance, in the live broadcast process of the video, the live broadcast video is constantly matched with the advertisements in the advertisement library in real time, so that the video segments belonging to the advertisements in the live broadcast video are determined, and are segmented and deleted. And then while eliminating the additional advertising information in the fragmented video providing the on-demand service, can also merge the program video segments separated by the advertisement but having the same semantics, have improved the integrity of the semantic content in the fragmented video, and has improved users' viewing experience.
Illustratively, at least one advertisement is inserted in the process of live program broadcasting, and video segments belonging to the advertisement in the live video are determined according to the real-time matching result with the advertisement library and are segmented and deleted. Or, if a host broadcasts a series of advertising words in the live program process, determining video segments belonging to the advertisements in the live video according to analysis of the voice broadcast by the host and matching with the advertisement library, and segmenting and deleting the video segments.
And step 130, editing the fragmented video and putting the fragmented video on the shelf to an on-demand website.
In the specific embodiment of the invention, the real-time dotting and strip splitting processing is carried out on the video which is broadcasted from the live video, and after the fragmented video with complete semantics corresponding to the video content which is broadcasted from the live video is obtained, the fragmented video is edited according to the video content of the fragmented video. The editing of the fragmented videos comprises cataloguing and classification processing, attribute information such as characters convenient to recognize is added to the fragmented videos, the fragmented videos are classified according to the attribute information, and the fragmented videos are put on the shelf to corresponding columns of the on-demand website according to classification results, so that users can quickly select and watch the videos. In this embodiment, starting with live broadcast of live video, splitting one or more videos with complete semantics, and then editing and shelving split videos, the whole production process of fragmented video is completely performed simultaneously with live broadcast of live video, and the time delay between the production completion time of one fragmented video and the live broadcast completion time of a live video segment corresponding to the fragmented video is very small. Therefore, when the live video is live, the user can abandon passive watching of the live video, and select active on-demand watching of fragmented video on the video content which is live out from the on-demand website, so that the user can watch the fragmented video corresponding to the live video in real time, the watched video does not contain any additional information such as advertisements, and the user can also adjust the playing progress of the video at will according to personal requirements or directly select the interested video content for watching.
According to the technical scheme, the current live broadcast video is synchronously recorded, the played part of the live broadcast video is separated into independent fragmented videos in real time, the fragmented videos are edited, and the fragmented videos are automatically uploaded to the on-demand website. The invention can display the video content which is live in the on-demand website in an independent video form within a very short delay time while the program is live by performing real-time strip splitting processing on the live video. The method provides a fragmented video browsing mode during live broadcasting for the user, and the user can directly select the fragmented video meeting the user requirement for on-demand watching from the broadcasted video content before the live broadcasting is finished.
Example two
In this embodiment, on the basis of the first embodiment, an optimal implementation of the method for converting the live video into the fragmented on-demand video is provided, which is capable of performing accurate and real-time strip breaking processing on the recorded video file of the live video according to the broadcast content of the live video. Fig. 2 is a flowchart of a method for converting a live video into a fragmented video on demand according to a second embodiment of the present invention, and as shown in fig. 2, the method includes the following specific steps:
and step 210, synchronously recording the live video which is currently live.
In the embodiment of the invention, when the live video starts to be played directly, the live video is synchronously recorded, so that the recorded video file corresponding to the live video of the on-demand service to be provided is obtained in real time.
And step 220, determining the division time point of the live video according to the broadcast content of the live video.
In the embodiment of the present invention, the fragmented video files provided for the user when the user requests the video file are usually video clips with complete semantics. For example, a complete news story in a news feed, or a complete song or a complete gadget in a live broadcast at a evening party. Therefore, the fact that the obtained fragmented video is a video clip with complete content at the first time of live video live broadcast of the user is guaranteed, and watching experience of the user is not influenced. Therefore, real-time monitoring of the broadcast content of the live video is particularly important to accurately and timely determine the split time point of the live video.
Preferably, the broadcast content of the live video is monitored in real time; and according to the broadcast content of the live video, when the broadcast of the program segments is finished, dotting the starting positions and the ending positions of the program segments in the synchronously recorded live video.
In a specific embodiment of the present invention, the content of the live video that is being played may be monitored and browsed in real time, and according to the content of the live video that is being played, when a certain video segment with a specific semantic meaning in the live video is played, the start position and the end position of the video segment are dotted in the recording file of the live video that is synchronously recorded, that is, timestamps are respectively established at the start position and the end position of the video segment. For example, if a real-time on-demand service is provided for a news simulcast, an editor synchronously watches the live broadcast of the news simulcast in real time, and when it is determined that a piece of news is played completely according to the live broadcast content, news introduction and switching of video pictures of a news simulcast host, the editor performs dotting on the start position and the end position of the piece of news, and establishes a timestamp for a video clip of the piece of news.
Or, preferably, extracting the voice audio and/or video picture of the live video in real time; and determining the segmentation time point of the live video according to the analysis result of the voice audio and/or the video picture.
In the specific embodiment of the invention, the real-time extracted voice audio and/or video pictures of the live video can be processed and analyzed in real time by adopting advanced technologies such as a lens detection technology, an audio fingerprint technology, a video database organization and index technology, a video retrieval technology based on motion characteristics, query-oriented characteristic extraction and matching and the like in an artificial intelligence mode, and the live video is automatically dotted and stripped by synthesizing the results of the real-time processing and analysis. For example, the mouth-broadcast voice of the broadcaster is extracted in real time, semantic analysis is performed on the voice, when the mouth-broadcast voice of the broadcaster is "please see next news" next, the playing of the first news is determined to be finished according to methods such as semantic analysis or keyword matching, and then dotting and strip breaking processing is performed on the recorded video file. By analogy, fragmented videos corresponding to each piece of news of the news simulcast can be obtained in real time respectively.
And step 230, performing video segmentation on the live video according to the segmentation time points.
And 240, acquiring a fragmented video corresponding to the program segment which is played currently by the live video according to the video segmentation result.
In a specific embodiment of the present invention, after the video segmentation time point of the live video is determined at the first time, a video segmentation technology may be adopted to perform video segmentation processing on the recording file of the live video, and segment the video segment with specific semantics into independent video files.
And step 250, cataloging the fragmented videos according to the video contents of the fragmented videos.
In the specific embodiment of the invention, the fragmented video is catalogued, that is, the fragmented video is added with additional attribute information such as characters and the like which are convenient to identify, including information such as video naming, abstract introduction writing, video live broadcast time, mark classification, coding parameters and the like, so that a user can intuitively select the fragmented video file through the catalogued information when the user does not open the video file, and the management of the system and the user on the fragmented video is convenient. For example, for a certain news broadcast in a news simulcast of 2 month and 10 days in 2018, the catalogable is as follows: 2018-2-10 news simulcast + news content + news evaluation.
And step 260, classifying the fragmented videos according to the cataloguing information.
In the embodiment of the present invention, since the catalog information is information content displayed in a text description form completely corresponding to the video content, the fragmented video can be classified according to the catalog information. For example, videos may be categorized into categories of video genres such as news, fantasy, sports, movies, and television shows, or subject matter such as winter olympics, spring evenings, and the like, which are currently popular.
And 270, according to the classification result of the fragmented videos, shelving the fragmented videos into corresponding columns of the on-demand website.
In the specific embodiment of the invention, correspondingly, different columns are set in the on-demand website, the columns can be set in multiple stages, and can be subdivided and sorted according to the date. Generally, videos which are split into strips and put on shelves in real time are arranged at the forefront position, namely, the forefront position of a column corresponding to an on-demand website of the video arrangement closest to the current time is arranged according to the live broadcast time of live videos, so that a user can obtain the latest or most timely fragmented videos at the first time. And the same video can be put on shelf to different columns in the on-demand website, so that the videos of the interested categories of the user can be selected in a classified manner according to different requirements of the user when the user browses the on-demand website.
For example, sports items may be further categorized into sports events such as football, basketball, etc. For a real-time game video in the winter Olympic Games, the video can be ranked into a specific game type column in sports columns according to classification, and meanwhile, the video can also be ranked into a column with the theme being the winter Olympic Games.
According to the technical scheme, the current live broadcast video is synchronously recorded, the recorded video files of the live broadcast video are accurately and timely stripped according to the broadcast content of the live broadcast video, the parts which are already broadcast in the live broadcast video are stripped into independent fragmented videos in real time, and the fragmented videos are cataloged and classified and automatically uploaded to the on-demand website. The invention can display the video content which is live in the on-demand website in an independent video form within a very short delay time while the program is live by performing real-time strip splitting processing on the live video. The method provides a fragmented video browsing mode during live broadcasting for the user, and the user can directly select the fragmented video meeting the user requirement for on-demand watching from the broadcasted video content before the live broadcasting is finished.
