That is, in each embodiment, a plurality of signals transmitted at a predetermined time interval or transmitted after receiving a response signal from a counterpart device may be expressed as one signal name for convenience.

A schematic configuration of an entire video content transmission/reception system including the video content output device 100 and the video content transmission server 200 according to an embodiment of the present invention is as shown in FIG. 1.

In the figure, the video content transmission server 200 provides video content according to the request of the video content output device 100, and in this embodiment, it is assumed that the video content is provided.

The functional blocks representing specific features of the video content transmission server 200 will be described after the video content output device 100 is first described.

The video content output device 100 receives and displays video content from the video content transmission server 200 according to a user's manipulation. Although a portable wireless communication terminal is shown in FIG. 1, the video content output device is not limited thereto. 100 may be a wired communication terminal such as a personal computer.

A detailed functional block diagram of the video content output device 100 is illustrated in FIG. 2.

As shown in the figure, the video content output device 100 according to an embodiment of the present invention includes a content extraction unit 110, a viewer determination unit 120, a comparison determination unit 130, and a content output control unit 140. , Identification information generation unit 150, image content generation unit 160, storage unit 170, may be configured to include a first camera module, a second camera module.

Here, the storage unit 170 includes data, information, or applications necessary for the operation of the video content output device 100, and further, data generated during the operation of the video content output device 100 or received from outside You can also store information.

The content extraction unit 110 performs a function of extracting user identification information included in the video content when a video content output is requested.

Here, the video content may be stored in the storage unit 170, but in this embodiment, it is assumed that it is received from the video content transmission server 200 as described above.

To this end, the video content must include user identification information in advance. For example, if the file header of the video content or the video content consists of a plurality of video frames, the above-described user identification information may be included for each video frame. Alternatively, when video content is received from the video content transmission server 200 in a streaming method, user identification information may be included in a predetermined header area of the streaming transmission unit.

Here, the user identification information is, for example, information input by a person who created the corresponding image content (for example, a photographer), and may be generated based on the outline of a face photographed by the photographer himself or an iris image of the photographer. .

The viewer determination unit 120 performs a function of generating viewer identification information by photographing a face of a viewer of video content using an already equipped camera module, that is, a first camera module.

That is, the first camera module is configured to photograph a predetermined subject, and may be composed of an image pickup device and a device for controlling the same. The configuration and function of the camera module for photographing a predetermined subject itself corresponds to a known technology. Detailed description is omitted.

In particular, since the first camera module is required to continuously or periodically shoot a viewer who wants to view video content (such as viewing a video), it is configured in the direction in which the display unit (not shown) of the video content output device 100 is located. This is desirable.

Here, the viewer determination unit 120 may generate viewer identification information based on at least one of an image photographing an outline of at least a portion of a face of a viewer of the video content and an image photographing an iris.

Since the face recognition technology and the iris recognition technology itself by photographing are known technologies, a more detailed description will be omitted.

The comparison determination unit 130 compares the user identification information extracted by the content extraction unit 110 with the viewer identification information generated by the viewer determination unit 120 to determine whether they match within a preset reference range. Perform.

For example, the comparison determination unit 130 may determine whether the user identification information and the viewer identification information exactly match, or as another example, may determine whether the error ratio is within 10%.

The content output control unit 140 controls the video content to be output when the user identification information and the viewer identification information match as a result of the determination by the comparison determination unit 130.

For example, the content output control unit 140 controls the video content to be output only when the user identification information exactly matches the viewer identification information.

As another example, the content output control unit 140 may control the output of the video content only when the error rate between the viewer identification information and the user identification information is within 10%. These error rates can be set in various ways.

Here, controlling the image content to be output means displaying the image content on the corresponding display unit when a predetermined display unit is already provided, and when interlocking with a predetermined display device (not shown), the display unit It means to transmit video content.

The output of video content means video playback in the case of a video, and still image display in the case of a still image.

In addition, the content output control unit 140 performs a function of controlling so that the video content is not output when the user identification information and the viewer identification information do not match.

For example, if the discrepancy between the user identification information and the browsing identification information is confirmed before the output of the video content, the content output control unit 140 does not output the video content itself, and further, the user identification information after the video content is output. If a discrepancy between and viewing identification information is confirmed, the output of the video content can be stopped and terminated.

That is, even after the video content is output by the content output control unit 140, the user identification information is extracted by the content extraction unit 110, the viewer identification information is generated by the viewer determination unit 120, and the comparison determination unit 130 The comparison determination between the user identification information and the viewer identification information may be made continuously or at a preset time interval, and at this time, the content output control unit 140 continuously or periodically by the comparison determination unit 130 even after the video content is output. It is possible to determine whether to continue the output of the video content currently being output based on the comparison determination made at a set time interval and to perform control according thereto.

Here, the preset time interval may be a physical time interval, or when the image content is a video content, it may correspond to a video frame interval.

Meanwhile, in the above description, each component has been described on the premise that user identification information is included in the video content, and such user identification information may be included by the video content output device 100.

To this end, the identification information generation unit 150 performs a function of generating photographer identification information by photographing a photographer's face using a camera module (ie, a first camera module) already provided when photographing a subject.

In this case, a camera module for photographing an actual subject and a camera module for photographing a photographer's face may be different from each other.

That is, in FIG. 1, the first camera module performs a function of photographing a photographer's face, and the second camera module performs a function of photographing a predetermined subject according to the intention of the photographer.

For example, the first camera module may be provided on the rear surface of the image content output device 100 (that is, the surface that the photographer can see when shooting), and the second camera module is the front side of the image content output device 100 (In other words, it may be provided on a side that the photographer cannot see when shooting).

Here, the photographer identification information generated by the identification information generation unit 150 may be the same as the viewer identification information generated by the viewer determination unit 120 and may be generated based on the photographer's face contour or iris image.

In particular, when photographing a subject is a video recording, the identification information generation unit 150 may generate the photographer identification information based on the face of the photographer photographed at the start of photographing by using the first camera module when photographing the subject video.

That is, the user identification information included in the image content extracted by the content extraction unit 110 may be the same as the photographer identification information generated by the identification information generation unit 150, for example, the image captured by the photographer and himself/herself. In the event that the content is to be viewed, the user identification information and the photographer identification information are eventually the same.

The image content generation unit 160 generates image content according to photographing a subject, but performs a function of including the photographer identification information generated by the identification information generation unit 150 in the image content.

That is, the video content generation unit 160 generates video content based on the result of photographing the subject through the second camera module and the result of photographing the face of the photographer through the first camera module. 2 To include the photographer identification information generated by the identification information generator 150 for each frame of the video content generated through the camera module or in the entire header of the video content.

At this time, when the subject is photographed as a video, the video content generation unit 160 generates the photographer identification information generated by the identification information generation unit 150 for each frame at a preset interval of the video content ( Each frame, every four frames, or every frame of a preset time interval) may be included.

In this case, the photographer identification information may be included in a specific area of each frame of the image content so that the photographer identification information is not displayed when the image content is reproduced.

Alternatively, the video content generation unit 160 may include the photographer identification information generated by the identification information generation unit 150 in a file system header area of a video content file generated according to photographing a subject video.

That is, if the photographer identification information is included only in the file system header area of the content file, one photographer identification information is included in one completed content file, and if the photographer identification information is included for each captured image frame, one A plurality of photographer identification information may be included in the completed content file.

On the other hand, when the video content is received from the video content delivery server 200, the video content delivery server 200 may perform special processing on user identification information, which will be described with reference to FIG. 3.

As shown in the figure, the image content transmission server 200 may include an image content selection unit 210, an extraction unit 220, an image content transmission unit 230, and a storage unit 240.

Here, the storage unit 240 includes data, information, or applications necessary for the operation of the video content transmission server 200, and further, data generated during the operation of the video content transmission server 200 or received from outside You can also store information.

The video content selection unit 210 performs a function of selecting the requested video content when a video content request signal is received from the video content output device 100.

For example, when a plurality of video content is stored in the storage unit 240, the video content selection unit 210 selects specific video content by analyzing a request from the video content output device 100.

In this embodiment, it is assumed that user identification information is stored in the header area of the video content file.

The extraction unit 220 performs a function of extracting user identification information included in the header of the video content selected by the video content selection unit 210.

The content transmission unit divides the video content selected by the video content selection unit 210 into a transmission unit and transmits it to the video content output device 100, and the user identification information extracted by the extraction unit 220 is sent to the header of each transmission unit of the video content. Can be dynamically included in the domain.

That is, when the video content transmission server 200 provides video content to the video content output device 100 in a streaming method, the video content can be divided into predetermined sizes according to network conditions, and provided. The transmission server 200 is capable of including user identification information in a header area of each division unit.

In this case, even if only one user identification information was included in the file header area of the video content, the user identification information may be included in the header area for each division unit of the video content received by the video content output device 100. As described above, the video content output device 100 may perform output control for each division unit during video content playback.
