Description
Technical Field
The present invention relates to the field of information processing technologies, and in particular, to a video cataloging method, a video cataloging system, an electronic device, and a storage medium.
Background
With the rapid development of broadcast television industry, media resources are increasingly abundant, and media asset management has grown. In order to increase the integration of the broadcast television media asset system and thus to make the media asset permanent, resource and productive, there is an urgent need for a digitalized and intelligent cataloging system which is convenient for searching and auditing.
Currently, when cataloging advertisements and programs in a television, the existing system mainly loads a player plug-in through a web page to play video files. Meanwhile, advertisements or program starting and ending time is searched by dragging a progress bar of the player in the process of the player, so that results are cataloged.
However, such cataloging systems often suffer from inaccurate boundaries of the cataloging results. Because the starting and ending time of the result is searched by dragging the progress bar, the boundary time point can be confirmed approximately only by feeling, and the marked result boundary is inaccurate, so that accurate statistics cannot be completed when the result duration is counted, especially when whether the advertisement broadcasting duration is illegal or not is confirmed. Moreover, cataloging in such systems often requires repeated cataloging of the same content multiple times, resulting in a significant increase in redundant cataloging operations. For example, the same advertisement may be played multiple times a day, which means that the same advertisement needs to be repeatedly cataloged multiple times when cataloging in such a system, and that the cataloging information such as the result name needs to be written for each result of the cataloging. When searching advertisement boundary on web page, it is difficult to drag progress bar of player smoothly, and when editing, it is very easy to clip, and efficiency is low. The input of the result name is mainly manual, and time and labor are wasted.

s3: the catalogue information of each segment of the video is determined and catalogue information is written; and
s4: automatically discovering fragments with the same content and carrying out batch bibliography on the discovered fragments with the same content to obtain the same catalogue information.
In this embodiment, various terms or phrases used herein have a common meaning well known to those of ordinary skill in the art, and even though the present invention is intended to be more fully described and illustrated herein. If the terms and phrases referred to herein have a meaning inconsistent with the known meaning, the meaning expressed by the present invention; and if not defined in the present application, have meanings commonly understood by one of ordinary skill in the art.
Specifically, video and audio data having a use value that can be used for producing a program are referred to as materials; the complete video and audio data which have independent theme significance and are manufactured are called programs; a combined program which is divided according to the content and the property of the television broadcast and has a fixed name and a broadcast period is called a column; a continuous video and audio segment of a program or material, which is composed of more than one scene associated with each other, is called a segment; a continuous video-audio portion of a program or material consisting of one or more shots that are temporally or spatially correlated with a background or scene that is constant is referred to as a scene; the continuous pictures shot by the same camera at one time are called a lens or a lens picture; the process of analyzing, summarizing and recording the content and formal features of video and audio material is called authoring/indexing; recording items for revealing the content and form characteristics of audio-visual data are called copybooks (also called catalogue information); the process of writing, indexing, or otherwise examining the content and formal features of the video and audio material for review or retrieval is referred to as cataloging.
In this embodiment, it should be noted that the video cataloging method includes: the fast preview video S2 specifically includes:
s21: extracting partial frame pictures of the video according to a preset time interval;
s22: storing part of the frame picture; and
s23: and displaying part of the frame picture.
Specifically, the preview manner of the video includes, but is not limited to: by shortcut key control, by mouse control, etc. More specifically, after the video is loaded into the cataloging system, the cataloging system automatically extracts video frames from the video content at set time intervals, and records the extracted video content into a memory, thereby rapidly browsing the video content and rapidly locating the boundary points of the results by means such as operating a shortcut key.
For example, the predetermined time interval may be set to 30 seconds, 1 minute, 2 minutes, 3 minutes, 5 minutes, or the like; however, although only the embodiments of the time intervals described above are described herein, it is apparent that the embodiments of the present invention are not limited thereto and those skilled in the art can select an appropriate time interval according to actual working needs.
In particular, video typically has at least 25 frames per second, so one day has at least 2160000 frames of video. However, a huge amount of frames cannot be completely browsed by a preloading manner, and thus, precise determination of catalogue information cannot be completed. Based on this, the present invention further provides embodiments such as the following to further achieve more accurate cataloging effects.
In this embodiment, it should be noted that the video cataloging method includes: the cataloging information of each segment of the video is determined and cataloging information is recorded S3, which specifically comprises:
s31: determining time boundary information of the clip based on the picture wall and the audio waveform map;
s32: identifying result name information of the segment by identifying text within the selection area;
s33: inputting information to be checked of the fragment; and
s34: and recording based on the time boundary information, the result name information and the information to be checked of the fragments.
Although S3 includes a plurality of specific steps described above, one of ordinary skill in the art may adjust, delete, or add sequences of steps as desired. For example, step S31 of the present invention may exchange order with S32, S33.
Specifically, the variety of cataloging information includes, but is not limited to: time boundary information (i.e., start time information and end time information of a program or a section), result name information (i.e., topic name information of a program or a section), to-be-checked information (e.g., result type information, result attribute information, violation type information, etc.), and the like. However, embodiments of the present invention are not limited thereto, and those of ordinary skill in the art may determine and write more catalogue information according to actual working needs.
For example, the information to be checked includes, but is not limited to, result type information, result attribute information, violation type information, and the like. Specifically, the result attribute information includes a plurality of primary result attribute information, each of the plurality of result attribute information includes at least one secondary result attribute information, respectively, and each of the partial secondary result attribute information includes at least one tertiary result attribute information, respectively.
Specifically, the primary result attribute information includes, but is not limited to: advertisement, channel propaganda, news propaganda, cultural and cultural science education, life service, variety entertainment, movie and television drama, standby and other categories. For example, the advertisement class serves as primary result attribute information, including, but not limited to, the following secondary result attribute information: general commercial advertisements, micro-commercial advertisements, medical advertisements, shopping short advertisements, affiliate advertisements, collection advertisements, and the like. Further, the generic commercial serves as secondary result attribute information including, but not limited to, the following tertiary result attribute information: education, home decoration, cosmetics, leisure and entertainment, drinks and foods, living goods, wearing goods, household appliances, agricultural services, industrial services, digital communication, propaganda services, books, audio and video, computer offices, transportation, real estate, financial services, tobacco and wine, general commercial advertisements and the like. As another example, news campaigns are used as primary result attribute information, including, but not limited to, the following secondary result attribute information: comprehensive political news, news messages, news topics, news live broadcasts, politics topics or historical literature sheets, news campaigns, and the like. As another example, the cultural relics class serves as primary result attribute information including, but not limited to, the following secondary result attribute information: cultural moral classes, scientific and teaching classes, sports classes, corporate and teaching propaganda classes, cultural relic and scientific and teaching other classes, and the like. As another example, the lifestyle service class serves as primary result attribute information including, but not limited to, the following secondary result attribute information: employment, beauty/apparel/fashion, diet, health, psychological/emotional consultation, dating, travel, home/property, automobiles, investment financial programs, weather forecast, television lottery, traffic, shopping programs, life service other categories, and the like. As another example, the variety entertainment class serves as primary result attribute information including, but not limited to, the following secondary result attribute information: interactive entertainment, variety shows, contest pulls, entertainment conversations/themes, genuine shows, variety entertainment reports, talk shows, large entertainment activities, entertainment other categories, and the like. As another example, a movie series class serves as primary result attribute information including, but not limited to, the following secondary result attribute information: television dramas, movies, column dramas, cartoon, film and television dramas, and the like. However, the embodiments of the present invention are not limited thereto, and those skilled in the art can select and write more result attribute information according to actual working needs.
Similarly, the violation attribute information and the violation type information also include various information that one of ordinary skill in the art can select according to actual working needs.
In this embodiment, it should be noted that the video cataloging method includes: the time boundary information S31 of the clip is determined based on the picture wall and the audio waveform map, which specifically includes:
s311: generating a picture wall of the segment;
s312: generating an audio waveform diagram of the segment;
s313: determining abrupt points of the picture wall and the audio waveform diagram near the time boundary points of the fragments; and
s314: recording the mutation points as time boundary information of the fragments, and calculating the duration of the fragments based on the time boundary information.
Although S31 includes a plurality of the specific steps described above, one of ordinary skill in the art may adjust, delete, or add the order of the steps as desired. For example, step S311 of the present invention may exchange order with S312.
In particular, the audio waveform map may be an audio feature map of the extracted video clip. In other words, in order to more conveniently, quickly and accurately determine time boundary information, the system extracts audio in video and performs time sequence presentation in a waveform manner. When clicking on the waveform, the system presents video content near the time node in real time on the picture wall.
For example, a discontinuity may be a temporal node (or referred to as a point in time) at which a significant change in a picture or waveform characteristic occurs. Specifically, the significant change in the picture characteristic may refer to a time node at which the scene or the shot of the extracted clip or the like is significantly switched, and the significant change in the waveform characteristic may refer to a time node at which the amplitude or the frequency or the like of the audio of the extracted clip is significantly changed.
In this embodiment, it should be noted that the video cataloging method includes: the generating a picture wall S311 of a clip specifically includes:
s3111: extracting each frame picture of the segment frame by frame;
s3112: storing each frame picture;
s3113: extracting a specified time point and all specific frame pictures in a specified time interval before and after the specified time point from each frame picture; and
s3114: and performing thumbnail processing on the specific frame picture, and performing visual display according to the time sequence to generate a picture wall.
In order to more accurately determine the time boundaries of the results in the video segments, the inventorizing system of the present invention provides the ability to browse each frame of picture in the video. The time boundary of the result is further determined on the basis of the above-mentioned audio waveform map by browsing each frame of picture. In other words, the audio waveform diagram and the picture wall cooperate to complete the function of determining time boundary information in the cataloging system, and in this way, the accuracy of cataloging is significantly improved.
In particular, a picture wall may be a picture set for each frame picture of the extracted video clip, i.e. a set comprising each frame picture extracted from frame to frame.
Furthermore, the cataloging system adopts a local real-time extraction function to dynamically release images which are not browsed recently in the memory in the picture wall, and only displays each frame picture within a specified time interval range of a specified time node, so that the resource loss of a machine is saved, and the requirement of the system on machine hardware is reduced, and meanwhile, the requirement of an accurate cataloging purpose is met. For example, the specified time interval may be 3 seconds.
In this embodiment, it should be noted that the video cataloging method includes: the result name information S32 for identifying the clip by identifying the text within the selection area specifically includes:
s321: selecting a designated area of a screen outputting the clip;
s322: recognizing characters in the selected appointed area in real time; and
s323: result name information of the segment is generated based on the recognized text.
The specified area may be an area of any area, any location of the screen on which the video clip is displayed.
In this embodiment, it should be noted that the video cataloging method includes: the result name information S4 for identifying the clip by identifying the text in the selection area specifically includes:
s41: creating a template based on the clips for which the copybook has been completed;
s42: retrieving segments in the video that are consistent with the template; and
s43: and utilizing the template to carry out batch writing on the fragments consistent with the template.
Specifically, after the segments are cataloged by the system, a relevant template is automatically created based on the cataloging result of the segments, then segments consistent with the template content based on the segments are searched in the video of the whole day, and the batch cataloging information of the same searched segments is recorded.
More specifically, when a certain brand of advertisement segment appears in the video of the whole day for a plurality of times, only one segment appears in the video is required to be recorded with inventory information once, and then the system creates a template on the basis, searches a plurality of segments consistent with the brand of advertisement segment, and records the same inventory information with the plurality of segments consistent with the template, thereby avoiding repeated and continuous inventory work of the inventory information with the same segment and improving the inventory efficiency of the inventory system.
The video cataloging system provided by the invention is described below, and the video cataloging system described below and the video cataloging method described above can be correspondingly referred to each other.
