JP5620038B2 - How to automatically archive and use video that suits your purpose - Google Patents

Description

  The present invention relates to a method for minimizing the storage capacity of a video archive device and facilitating video search.

  In recent years, the use value of video has increased, and the demand for accumulating and confirming past video has increased. However, in order to accumulate all video for several years, a device with a huge storage capacity is required and it is too expensive to spread. Therefore, there is a need for a method for narrowing down the video to be accumulated. In addition, there is a need for a method for searching for the necessary video from the vast archived video.

  Up to now, when archiving videos automatically, there is only a large-scale system that stores only the videos broadcast by the local station, such as those in broadcast stations, in units of programs, and all necessary videos across multiple broadcast stations. It is impossible to automatically archive files, and a method of accumulating pieces on a DVD or a hard disk has been taken.

  However, even today, when the importance of archiving accumulated video and searching and using it when it is needed has increased, metadata relating to the required video and its contents is automatically archived according to predetermined rules. There was no way to do it.

  The present invention has been made in view of the above circumstances, and if it is a broadcast program, it records all the programs of all the broadcast stations selected by the user and converts the content of the video and the program title into text, For metadata with national broadcasting station codes and accurate time codes in seconds, etc., information on the required video is set in advance or afterwards using one or more keywords, and the metadata is automatically set. The video corresponding to the extracted metadata is automatically edited and cut out according to the national broadcasting station code, the accurate time code in seconds, etc., saved on the hard disk etc. with the extracted metadata, and the video is required At that stage, search for extracted metadata using one or more keywords, the time of recording, etc. Shown, the user has an object to provide a method for viewing desired video by selecting the text.

According to the first aspect of the present invention, the contents and titles of all the video files formed by recording and accumulating all the broadcasting programs of all broadcasting stations are recorded 24 hours a day, and converted into texts. A metadata forming means for generating metadata by setting a keyword based on video content or a title and generating metadata, and giving a precise time code of a unit, and forming a metadata file and storing it in a database. A metadata file forming means for extracting a predetermined metadata from the database to form a metadata file based on the above, and a video corresponding to the metadata file is extracted from all the video files to create a cut video file Cut-out video file creation means, the metadata file and the metadata file And having a cut already video file storage means for storing cut already picture file corresponding to Le.
The invention according to claim 2 is characterized in that the automatically cut video is automatically saved together with metadata related to the video in real time or in batch processing in units of one day or several days.
In the invention according to claim 3, when searching for the necessary video from the archived video, the metadata stored together with the video is searched at the time when one or a plurality of keywords and recordings are performed. , Text related to the viewing candidate video is displayed on the screen of the video archive device main unit or a PC connected to the LAN or the Internet, and by selecting any text on the screen, the national broadcasting station code of the metadata and the accuracy in seconds It is possible to search and display by a time code and to classify and manage archived video and metadata.
In the present invention, all programs of all broadcast stations selected by the user as long as they are broadcast programs are MPEG-2, MPEG-4, H.264. The digital video recording is performed on the video archive device in a state where the video is compressed using a method such as H.264.

  The video content and program title are converted into text, and metadata with national broadcasting station codes and accurate time codes in seconds is created and stored in the database. A database storing this metadata may be provided by a vendor.

On the other hand, necessary video information is set in advance or afterwards using one or more keywords, and metadata acquired or created using the set one or more keywords is automatically searched. The video corresponding to the extracted metadata is automatically cut according to the national broadcasting station code, the accurate time code in units of seconds, etc., and stored together with the extracted metadata in a storage device such as a hard disk.

  When a video is needed, search for the extracted metadata stored in the archive device using one or more keywords or the time when the video was recorded, etc. By making the user select the text of the desired content, the user can view the video of the content desired by the user from the extracted national broadcasting station code and the accurate time code in seconds.

Moreover, in the case of television broadcasts, the broadcast programs of all broadcast stations selected by the user are recorded 24 hours a day, recorded daily and sorted by one or more keywords, and only the minimum necessary images are recorded. By cutting out, you can save about 5 years of video on a collective hard disk of only about 2 terabytes.

  In addition, the system of the present invention is a low-cost video archive for all programs of all broadcast stations selected by the user, even for large broadcast stations such as NHK. It can meet the needs of individuals and companies that are creating the need to store increasingly large volumes of video.

  In addition, when the storage capacity of the archive device becomes full, the necessary video can be archived for another five years by additionally installing another new archive device on the local network.

  In the present invention, all broadcast programs of all broadcast stations selected by the user are automatically recorded every day for 24 hours and stored in all video files 1.

  The video contents and program titles stored in all video files 1 are converted into text by recognition technology or manual work, and a video content text file 2 is created.

  The video content text file 2 is provided with a national broadcasting station code and an accurate time code in units of seconds and stored in a database, and a video metadata database 3 is created. This operation is performed by the metadata forming means. The video metadata database 3 may be provided by a vendor.

  The video metadata database 3 is searched with one or a plurality of keywords set in advance or afterwards, and as a result, an extracted metadata file 4 is created. The above operations are performed by the metadata file forming means.

  Only the portion of the video corresponding to the extracted metadata file 4 is automatically copied or moved into the cut video file 5. This operation is performed by the cut-out video file creation means.

  The cut video file 5 is stored together with the extracted metadata file 4. This work is performed by the video file storage means.

  The video stored in all video files 1 is automatically deleted from video that has passed a certain period since recording.

  When the user of the present invention searches for a desired video, the extracted metadata file 4 is searched by one or a plurality of keywords, the time when recording was performed, or the like.

  If an extracted metadata file 4 that matches one or a plurality of keywords input by the user, a recording time, etc. is found, it is displayed on the screen in the form of candidate video text 6.

  When the user selects an arbitrary one from the candidate video text 6, the corresponding cut video file 5 can be viewed.

  As a result of viewing, the extracted metadata file 4 corresponding to the video that the user determines to be particularly important or to be managed separately can be copied to the selected grouped metadata file 7.

It is possible for users of the embodiments of the present invention to efficiently archive videos by using metadata and keywords, and to efficiently find and view desired videos from among the vast archived videos. It is explanatory drawing explaining the concept of the method to make.
