Throughout the disclosure, like reference numerals refer to like parts throughout the various figures and embodiments of the present invention.
In general, when a contents consumer consumes contents, a sensory effect may be reproduced by a corresponding sensory reproduction apparatus according the consumed contents. Since relations and compatibilities between the consumed contents and the sensory reproduction apparatuses may be different, a sensory reproduction apparatus compatible with contents is required to reproduce sensory effects for the contents.
Meanwhile, the sensory effect is used as a means that enables a contents consumer to more realistically experience contents, but the sensory effect for reproducing colors intended by a contents provider in a sensory reproduction apparatus is not provided. That is, since contents providing environment and characteristics of the sensory reproduction apparatus are different, it is difficult to reproduce pictures identical to original pictures of the contents in the sensory reproduction apparatus.
In accordance with the present invention, color correction effect information on contents is provided to a sensory reproduction apparatus, so that colors intended by a contents provider can be reproduced in the sensory reproduction apparatus. That is, in accordance with the present invention, color information on original pictures of contents and information on a target for color correction are provided to a sensory reproduction apparatus, so that pictures intended by a contents provider or pictures identical to the original pictures of the contents can be reproduced in the sensory reproduction apparatus.

The sensory reproduction apparatus 113 may represent colors of original pictures for the contents with reference to the Color Correction Parameter.
As illustrated in
At the step S6401, the USP metadata generating unit 103 generates USP metadata including consumer preference information on a sensory effect.
At step S6403, the USP metadata generating unit 103 transmits the USP metadata to the sensory reproduction apparatus engine unit 109. The sensory reproduction apparatus engine unit 109 receives the USP metadata transmitted from the USP metadata generating unit 103 so as to analyze the USP metadata and generate control information on the sensory reproduction apparatus 113.
The consumer preference information on the sensory effect may include preference information on the color correction effect as described in

The reproduction capability information may include reproduction capability information on the color correction effect for the contents as described in
As illustrated in
At the step S6601, the sensory reproduction apparatus engine unit 109 receives SEM including sensory effect information. The sensory reproduction apparatus engine unit 109 may receive the SEM inputted from the SEM generating unit 101.
At step S6603, the sensory reproduction apparatus engine unit 109 transmits SDCmd metadata to a control device for controlling the sensory reproduction apparatus 113. The control device for controlling the sensory reproduction apparatus 113 may be a control device included in the sensory reproduction apparatus control unit 111 or the sensory reproduction apparatus 113.
Meanwhile, the method in accordance with the embodiment of the present invention may further include receiving USP metadata including consumer preference information on the color correction effect or receiving SDCap metadata including reproduction capability information on the color correction effect of the sensory reproduction apparatus 113. The sensory reproduction apparatus engine unit 109 may generate and transmit SDCmd metadata by additionally analyzing the USP metadata or SDCap metadata.
The sensory effect may be a color correction effect for contents. Thus, the SEM may include color correction effect information on the contents, and the USP metadata may include consumer preference information on the color correction effect. The SDCap metadata may include reproduction capability information on the color correction effect of the sensory reproduction apparatus 113.
The sensory reproduction apparatus 113 that receives the SDCmd metadata including the color correction effect information on the contents may represent the color correction effect based on the SDCmd metadata. That is, the sensory reproduction apparatus engine unit 109 analyzes the color correction effect information including color correction parameters and generates the SDCmd metadata so that the sensory reproduction apparatus 113 can represent the color correction effect according to the color correction parameters. The sensory reproduction apparatus 113 may represent the color correction effect according to the color correction parameters, or may represent the color correction effect according to the Spatio Temporal Locator and the Spatio Temporal Mask for a color correction range.
As illustrated in
At the step S6701, the sensory reproduction apparatus 113 receives control information on a sensory effect of the sensory reproduction apparatus 113. The control information on the sensory effect may be inputted from the sensory reproduction apparatus control unit 111 that receives SDCmd metadata, or may be inputted in the form of SDCmd metadata from the sensory reproduction apparatus engine unit 109.

According to the embodiment of the present invention, metadata for various sensory effects may be generated depending on the metadata description structure described above, and the various sensory effects may be represented in the sensory reproduction apparatus. For example, the sensory reproduction apparatus for representing sensory effects has base device command type metadata, and the base type metadata may be extended to metadata for the type of each sensory reproduction apparatus. Various metadata may be included as elements of reproduction apparatus type metadata or sensory effect information of the sensory reproduction apparatus and parameter information related to the sensory effect in the extended metadata. Here, the various metadata includes original color restoration setting information on contents, illuminance reproduction setting information, vibration setting information, temperature reproduction setting information, reproduction intensity setting information of each sensory reproduction apparatus, and the like.

In Tables 30 to 34, the SEM produced by the advertisement producer is shown in an XML instance form. Specifically, Tables 30 to 34 show SEM metadata for describing parameters for original color correction intended by the advertisement producer, correction information (range and changed position) on a color correction object, an illumination effect, a temperature effect, a wind effect, and the like. Tables 30 to 34 are shown in the consecutive XML instance form.
The advertisement contents and the advertisement moving picture contents 6300 may be generated in the form of a multimedia application format (MAF). The generated advertisement moving picture contents 6300, i.e., media are transmitted to the sensory reproduction apparatus engine unit 109, and a consumer of the advertisement moving picture contents 6300 can see that there exists a sensory effect for the advertisement contents.
Thus, the consumer selects whether or not to apply the sensory effect for the transmitted advertisement moving picture contents 6300. That is, the consumer may select the presence of preference for the sensory effect using a graphic user interface (GUI) of the sensory reproduction apparatus 113. Accordingly, the generated USP metadata is transmitted to the sensory production apparatus engine unit 109.
In Table 35, the USP metadata showing preference of the sensory effect for the advertisement moving picture contents 6300 is represented in an XML instance form. That is, Table 35 shows the USP metadata for describing sensory effect reference information of the consumer. Here, the USP metadata use all the original picture color correction effect, the main illumination effect, the peripheral illumination effect, the temperature effect and the wind effect, and describe a degree of the reproduction effect of illumination, temperature and wind control.
The sensory reproduction apparatus engine unit 109 receives the SEM 200 for reproducing the sensory effect of the advertisement moving picture contents 6300, the SDCap metadata 4300 of a peripheral device (a main illumination and peripheral illumination (LED), an air conditioner or the like) connected to the sensory reproduction apparatus control unit 111, and the USP metadata 3400 that are sensory effect reproduction preference information of the consumer so as to generate the SDCmd metadata 5200.
In Table 36, the SDCap metadata 4300 generated from the sensory reproduction apparatus control unit 111 is shown in an XML instance form. Table 36 describes the reproduction capability range of a main illumination device (dimmer), a peripheral illumination device (LED), and a temperature and wind control device (air-conditioner).
While the advertisement contents are reproduced, the sensory reproduction apparatus engine unit 109 analyzes the SEM 200 and the SDCap metadata 4300 and decides a currently available sensory reproduction apparatus in the sensory effect intended by the contents provider. Then, the sensory reproduction apparatus engine unit 109 finally analyzes consumer preference information based on the USP metadata of the consumer and transmits the generated SDCmd metadata 5200 to the sensory reproduction apparatus control unit 111.
In Tables 37 to 39, the SDCmd metadata 5200 generated from the sensory reproduction apparatus engine unit 109 is shown in an XML instance form. Tables 37 to 39 show the SDCmd metadata 5200 including control information on a sensory effect, controlled based on the USP metadata 3400 of the consumer, and describe control information on the original color correction effect, the main illumination and peripheral illumination (LED) effect, and the temperature and wind control effect. Tables 37 to 39 are shown in a consecutive XML instance form.

The sensory reproduction apparatus control unit 111 transmits a control signal to each of the sensory reproduction apparatuses based on the SDCmd metadata 5200. The sensory reproduction apparatus 113 that receives the control signal reproduces (represents) the sensory effect intended by the advertisement producer to the consumer in response to the control signal.
For example, a beer advertisement will be described as advertisement contents. In a case where pictures of cool sea under intense sunlight are reproduced, a specific range or the original color sense of an object (beer or sea) or all the pictures is displayed as an advertisement producer intends. Further, illumination may be intensely spotlighted, and a peripheral LED (peripheral illumination) may emit blue light. Furthermore, cool wind of an air-conditioner may be blown from the back of a consumer. The consumer may feel the urge to purchase an advertisement product while watching such advertisement media.
In a case where the consumer does not prefer a sensory effect, pictures without a color correction effect intended by the contents provider are displayed in a display device. That is, pictures according to color characteristic of the consumer's display device are displayed in the display device, and the advertisement effect for the consumer may be reduced.
In Table 40, the USP metadata when a consumer does not prefer a sensory effect is shown in an XML instance form. Table 40 describes that the original color correction effect, the main illumination and peripheral illumination (LED) effect, and the temperature and wind control effect are not used.
As described above, the method for providing metadata for a sensory effect and the method for reproducing the sensory effect in accordance with the present invention can be written using computer programs. Codes and code segments constituting the programs may be easily construed by computer programmers skilled in the art to which the invention pertains. Furthermore, the created programs may be stored in computer-readable recording media or data storage media and may be read out and executed by the computers. Examples of the computer-readable recording media include any computer-readable recoding media, e.g., intangible media such as carrier waves, as well as tangible media such as CD or DVD.
A computer-readable medium in accordance with an embodiment of the present invention includes SEM including sensory effect information on contents. The sensory effect information includes color correction effect information on the contents.
A computer-readable medium in accordance with another embodiment of the present invention includes USP metadata including consumer preference information on a sensory effect. The preference information includes preference information on a color correction effect of contents.

The reproduction capability information includes reproduction capability information on a color correction effect of contents.
A computer-readable medium in accordance with another embodiment of the present invention includes SDCmd metadata including control information on a sensory effect of a sensory reproduction apparatus. The control information on the sensory effect includes control information on a color correction effect of contents.
Hereinafter, an apparatus and method for implementing sensory effect metadata using binary representation of the sensory effect metadata will be described.
