When the registrant stops the screen, the IPTV set-top box 14 extracts (captures) several frames before and after the thumbnail based on the still picture of the time zone (location) where the registrant requests the screen stop, and shows them together. The registrant can select his own still image. At this time, the still image selected by the registrant is stored in the location information database (DB) 12.

Subsequently, when the location registration function is used in the still image, the electronic map from the electronic map providing server 11 is displayed on the screen, and the registrant directly designates his / her desired location, or the place name / mutual name / building name / address / telephone. A specific location may be searched on the electronic map using information such as a number. When a registrant designates a location and then registers, location information designated by the registrant is tagged on a specific still image of the video content.

The tagged information is stored in the location information database (DB) 12 including a registrant identifier, a registration date and time, time offset information, a spot identifier, and a still image identifier so that other users can check the location of the current video content on a map. It can be used for various interactive services. The registrant's electronic map location information registration and the user's location information confirmation procedure are all implemented in a simple interface based on the electronic map, so that the user can easily use it.

As described above, according to the present invention, after viewing the video content selected by the registrant, the video is stopped in a specific scene, and the actual location information corresponding to the still picture is selected through the interactive service and the electronic map of the IPTV. Register with information.

In addition, the present invention stores the time offset information of a specific still picture of the moving picture content (real time video or moving picture, etc.) selected by the registrant, and the identifier information of the spot registered or selected by the registrant on an electronic map in a table form. Provides electronic map-based location-based service to other users when playing the video content (real time video or video).

In addition, the present invention captures (extracts) a specific still image selected by the registrant, tags and registers a spot on the electronic map registered or selected by the registrant, and uses this information to provide the other user with an electronic map based location-based service. To provide.

Next, in order to help the understanding of the present invention, the treatment process according to the present invention will be described as follows.

First, a viewer who requests tagging location information on a specific still image of the video content or a user who wants to receive a service through location information registered by another registrant is requested to watch the video content through an IPTV service.

Thereafter, the registrant who wants to tag the location information on the specific still image of the moving image content is requested to stop the moving image content (real time image or moving image).

Then, in order to provide an accurate still image desired by the registrant, frames of the previous and second frames are extracted based on the current still image frame, and the still images are displayed to the registrant.

Thereafter, a specific still picture frame is selected by the registrant.

Subsequently, the location information of the extracted still image is searched for by a place name, a trade name, a building name, an address, a telephone number, or the like on the electronic map, or the target location of the extracted still image is found through the electronic map manipulation of the registrant. Directly assigned by the registrant.

Thereafter, the designated target location is registered as a spot or a spot that another registrant has already registered is selected from the registrant.

Thereafter, the time offset information of the still image selected by the registrant and the location information on the electronic map are tagged to the video content.

Thereafter, the registered or tag the selected still picture on the spot selected by the registrant.

Meanwhile, the user informs the user of the location information tagged with the location information while watching the video content through the IPTV service.

Subsequently, the location-based service associated with the location information of the video content is provided to the user by using the interactive service of the IPTV.
