The central server 200 can generate the haptic media content by combining the haptic effect metadata received from the haptic media content editing framework 100 with the media content corresponding to the haptic effect metadata. For example, the haptic-type media content editing framework 100 can check the media content information contained in the haptic effect metadata and retrieve the media content corresponding to the confirmed media content information. The sensible media content can be generated by combining the sensory effect metadata received in the retrieved media content.

According to an embodiment, the central server 200 may receive the tasteful media content from the tasteful media content editing framework 100 and store it.

The central server 200 transmits the sensible-sensible-type media content generated by itself or the sensory-feeling-type media content received from the sensory-feeling-type media content editing framework 100 to the local server 300 existing in each region (country and city) .

The central server 200 can receive information on a preferred haptic effect for each region from the haptic-type media content editing framework 100. [ In this case, the central server 200 can modify the haptic effect metadata of the sensible-type media contents stored by the central server 200 based on the received haptic effect information.

The central server 200 can receive the modified haptic effect metadata reflecting the haptic effect preferable for each region from the haptic-type media content editing framework 100.

In step 311, the haptic-type media content reproduction device 500 can reproduce the haptic-type media content based on the analyzed user feedback information. The reproduction of the haptic-type media content may mean modifying the haptic effect metadata of the haptic-type media content. That is, it may mean modifying only the haptic effect metadata without modifying the media content.

At step 313, the haptic-type media content reproduction device 500 can transmit the reproduced haptic-aware media content to the local server 300. [ Accordingly, the local server 300 can provide the sensible-type media contents reproduced to the reproduction servers 400 managed by the local server 300. [

In step 315, the haptic-type media content reproduction device 500 may transmit the analyzed user feedback information to the haptic-type media content editing framework 100. [

In step 319, the haptic-type media content editing framework 100 can transmit information on a preferred haptic effect to the central server 200 in each region.

In step 321, the central server 200 may transmit information on a preferred haptic effect for each region to the local server 300 located in the corresponding region.

In step 323, the local server 300 can reflect the haptic effect received from the central server 200 on the haptic media content. For example, the local server 300 may modify the haptic effect metadata of the haptic-type media content based on the haptic effect information received from the central server.

Meanwhile, as another embodiment, the haptic-type media content editing framework 100 may generate haptic effect metadata for each region on the basis of a preferred haptic effect for each region. In this case, the generated haptic effect metadata for each region can be transmitted to the local server 300 via the central server 200. Alternatively, the central server 200 can reproduce the haptic-type media content by reflecting the region-specific haptic effect metadata, and transmit the reproduced haptic-type media content to the local server 300.

The packet analysis unit 410 may transmit the media content to the media content playback unit 420 and transmit the haptic effect metadata to the haptic effect providing unit 430. [

The media content reproducing unit 420 can reproduce the media content received from the packet analyzing unit 410. For example, the media content playback unit 420 may display a moving image on a video output device such as a video screen by reproducing the moving image content received from the packet analysis unit 410.

The hapticizer 430 may analyze the haptic effect metadata received from the packet analyzer 410 to perform an operation for providing a haptic effect. For example, when the haptic effect metadata is for providing a vibration effect, the hapticizer 430 may provide a vibration effect to the user by controlling a haptic device capable of generating vibration.

The hapticizer 430 may control the haptic effect based on the information managed by the haptic situation information management unit 440 when performing an operation for providing a haptic effect. For example, suppose that the haptic metadata defines a vibration effect of intensity 10 at a particular point in time. In this case, if the information managed by the haptic-feeling-information managing unit 440 specifies that the user is pregnant with the information, the haptic-effect providing unit may provide a vibration effect of intensity 1 instead of providing a vibration effect of intensity 10, It can be prevented from being provided at all.

The haptic situation information management unit 440 can receive and manage information to be used for providing the haptic effect.

The haptic situation information may include at least one of a user profile, haptic device information, and user environment information.

The user profile may include physical information such as sex, age, and height. The user profile may also include information about things that may negatively respond to physical effects such as impairment and pregnancy. The user profile may also include job and user setting information.

The haptic device information may include information on the type and performance of the haptic device.

The user environment information may include information that may affect the provision of a haptic effect. For example, the user environment information may include weather, time, user residence information, user location information, and information received from various sensors located around the user.

At step 501, the reproduction server may receive the sensible media content from the local server.

At step 503, the reproduction server may extract the media content and the haptic effect metadata from the haptic-type media content received from the local server.

In step 505, the reproduction server can create a haptic effect table using the extracted haptic effect metadata. For example, the reproduction server may include a device capable of providing each haptic effect based on the information contained in the haptic effect metadata, a control code instructing control of the haptic effect, and a time to provide the haptic effect A haptic effect table that defines at least one of the haptic effect tables can be created.

In step 507, the reproduction server can extract the current reproduction time information, which is the time information on the part currently being reproduced, while reproducing the media content.

In step 509, the reproduction server checks whether the haptic effect corresponding to the extracted current reproduction time information is defined in the haptic effect table, and proceeds to step 511 if it is defined.

At step 511, the reproduction server may perform an operation for providing a haptic effect. For example, the reproduction server can refer to the haptic effect table and transmit a control code corresponding to the current reproduction time information to the haptic device corresponding to the current reproduction time information.

According to the embodiment, the reproduction server may create a haptic effect table that specifies the haptic effect and the time to provide the haptic effect using the extracted haptic effect metadata. In this case, the reproduction server can generate the control code to be transmitted to the haptic device in consideration of the haptic situation information. For example, suppose that the haptic effect provided at the current playback time is temperature. In this case, as shown in Figs. 10 and 11, the reproduction server generates a control code for controlling the cooling device or the heating device in consideration of the ambient temperature obtained at the current point of time and outputs the generated control code to the haptic effect device Lt; / RTI >

At this time, the reproduction server can modify the experience effect to be provided to the user based on the pre-stored feeling information, or prevent the experience effect from being provided.
