It is an excellent feature data transmitter.

  The preferred embodiment of the present invention will be briefly described by showing the operation of the present invention.

  When feature data is extracted from a broadcast video broadcast from a broadcaster's broadcast station, and this feature data is transmitted to the server of the video sharing site (administrator), the feature data and the feature of the uploaded video data on the server Are compared to determine whether the video is an illegal video, and the video data is deleted.

  At this time, in the feature data transmitting apparatus of the present invention, for example, by adding electronic program guide information (so-called iEPG information) on the Internet to the feature data, information (metadata) for clarifying the original broadcast video manually. The original broadcast video of the feature data can be clarified without the need to create data).

  Therefore, according to the present invention, for example, it is not necessary to manually search for illegal videos from video contents uploaded to a video sharing site, and feature data extracted from broadcast videos that are always broadcast from a broadcasting station is stored in a server. It can be automatically transmitted, so that most of the work can be automated and the burden on manpower can be greatly reduced.

  In addition, for example, when the feature data transmission device includes a format adjustment unit that adjusts the feature data to a format that conforms to the format used by the illegal movie determination unit of the server, the format of the feature data is determined as an illegal movie determination. Video content uploaded immediately on the server side (video sharing site administrator side) without having to adjust the format on the server that received the feature data because it can be sent to the server in a state adjusted to the format used by the means It can be determined whether or not is an illegal video.

  Specific examples of the present invention will be described.

  In this embodiment, a client terminal having feature data extracting means for extracting feature data from a broadcast video broadcast from a broadcasting station, and transmitting means for transmitting the feature data to a server, and the feature transmitted from the client terminal. In an illegal video determination system configured with a server having illegal video determination means for comparing data and characteristics of uploaded video data uploaded to determine whether the video is illegal, the client terminal includes the feature data Electronic program guide information adding means for adding electronic program guide information including at least the program name and broadcast date and time of the broadcast video, and a format for adjusting the feature data to a format used by the illegal video determination means of the server Adjusting means, and the transmitting means is for each predetermined amount or every predetermined time. The feature data is automatically transmitted to the server, and the feature data can be identified by the transmission means in a state where the original broadcast moving image can be identified and can be immediately used by the illegal moving image determination means. Is configured to automatically transmit to

  As the server and client terminal (feature data transmission device) of the present embodiment, a computer having a general function can be adopted. Specifically, an arithmetic processing unit such as a CPU functions as each of the above-described units based on a program stored in a storage device (storage unit) such as an HDD. , A CPU, and storage devices such as RAM, ROM, and HDD, which are connected to each other via a system bus, and the CPU performs four arithmetic operations based on OS programs and application programs stored in the HDD and the like. And various hardware operations and hardware control. In addition to the CPU and the storage device, a computer including a pointing device such as a mouse, an input device such as a keyboard, a display device such as a display, a storage medium reading device such as a recording medium drive, and the like can be employed as necessary.

  The server and the client terminal are each connected to a network (electronic communication line) such as the Internet and configured to be able to communicate with each other.

  In this embodiment, for example, the client terminal is a PC used by a content sender such as a broadcaster (a broadcasting station that broadcasts various broadcast programs) and capable of capturing (recording) video signals, and the server Will be described below as a server such as an administrator of the video sharing site.

  In the client terminal, a broadcast program from a broadcasting station is recorded (stored in a storage device), and electronic program guide information (iEPG information) on the Internet is acquired (stored in a storage device) via the Internet. The iEPG information includes channel information, broadcast date, broadcast start and end times, at least a program ID that is uniquely determined within the same day, and a program title.

  Then, the feature data is extracted from the recorded broadcast program (recorded in the recording device until the end of the broadcast) by the feature data extraction means, which will be described later, and the iEPG information is used by the electronic program guide information adding means. At least the program name and broadcast date and time (program title, broadcast date, broadcast start and end time) corresponding to the extracted program are extracted, and the original broadcast video (program) of the feature data can be identified. Attach (associate) and store in the storage device. Note that a technique for associating the electronic program guide information with specific data is a known technique, and thus detailed description thereof is omitted. Data based on the electronic program guide information is used as metadata in the server.

  The technique for extracting feature data and using this to search for videos having similar characteristics from a myriad of video data is a well-known technique, so detailed description is omitted, but feature data extraction means and illegal video determination are omitted. As a means, for example, a part of a moving image that is cut out as a still image and a moving image including a similar still image is determined as an illegal moving image can be employed.

  Specifically, in the present embodiment, the feature data extraction unit is configured to take out still images at arbitrary intervals from a program recorded in the client terminal. Further, the format adjusting unit resizes the stored still image so as to have a size and storage format that matches the format used by the illegal moving image determination unit of the server, and stores the same in the storage device as compressed data such as a JPG file. It is composed. Therefore, the feature data does not require format adjustment in the server, and can be immediately compared with the uploaded moving image data.

  Further, when the feature data is received by the server, the illegal movie determination means searches and extracts movie data having the same feature data from the uploaded movie data stored in the storage device, and stores it in the storage device. Uploaded video data that has been searched and extracted may be configured to be automatically deleted (or made unviewable), or after manual confirmation, the selected specific data is deleted (or made unviewable) ). Note that it is possible to recognize the identity of a program (works) if there is a still image of one frame per few minutes.

  Further, the feature data is automatically transmitted to the server every predetermined amount or every predetermined time by the transmitting means. For example, feature data is automatically extracted from all programs broadcast from a broadcasting station received at the client terminal and stored in the storage device, and each data is linked to the electronic program guide information and sequentially or at a predetermined timing. By configuring each means to collectively transmit to the server via the Internet, it becomes possible to search and delete illegal videos related to the program immediately after the broadcast program is automatically broadcast for 24 hours.

  In the present embodiment, the configuration is as described above. However, the format adjustment means may be provided on the server side.

  Since the present embodiment is configured as described above, the feature data is extracted from the broadcast video broadcast from the broadcasting station, the feature data is transmitted to the server of the video sharing site (administrator), and the video uploaded on the server When comparing the feature of the data and the feature data to determine whether it is an illegal movie, and deleting the movie data, etc., by adding iEPG information on the Internet to the feature data, the original broadcast one by one The original broadcast video of the feature data can be clarified without having to create information for clarifying the video.

  In addition, since the format of the feature data can be transmitted from the client terminal to the server in a state adjusted to the format used by the illegal video determination means, the server side (video sharing It is possible to search and determine whether or not the video content immediately uploaded by the site administrator) is an illegal video.

  Accordingly, it is not necessary to manually search for illegal videos from the video content uploaded to the video sharing site, and the feature data extracted from the broadcast video broadcast from the broadcasting station is automatically transmitted to the server for 24 hours. It is possible to search, so that most of the work can be automated, and the burden on manpower can be greatly reduced.
