Abstract

A method and apparatus are provided for generating emotional information including a user'"'"'s impressions in relation to multimedia content or meta data regarding the emotional information, and a computer readable recording medium storing the method. The meta data generating method includes receiving emotional information in relation to the content from at least one client system which receives and reproduces the content; generating meta data for an emotion using the emotional information; and coupling the meta data for the emotion to the content. Accordingly, it is possible to automatically acquire emotional information by using the facial expression of a user who is appreciating multimedia content, and use the emotional information as meta data.

Claims

1. A method of providing content, the method comprising:

receiving emotional information in relation to the content from a client that is generated by;

providing the content to a user;

acquiring multiple images of the user;

extracting facial information from the user images; and

generating the emotional information corresponding to the facial information;

generating information about a representative type of emotion associated with the emotional information received from the client;

updating an Electronic Program Guide associated with the content or a header of the content using the information about the representative type of emotion; and

providing the content with the updated Electronic Program Guide or the updated header to the user so that the user can reproduce portions of the content based on the emotion.

2. The method of claim 1, further comprising:

providing the content with the updated Electronic Program Guide or the updated header to a client system which requests the content.

6. The method of claim 1, wherein the updating comprises:

adding the information about the representative type of emotion to existing emotional information in meta data of the content in the Electronic Program Guide or in the header.

7. The method of claim 1, wherein the receiving comprises receiving the emotional information from several client systems of different users, and

the generating comprises integrating the emotional information received from the several client systems to determine the representative type of emotion.

3. A non-transitory computer readable recording medium storing a computer program for performing a method of providing content, the method comprising:

receiving emotional information in relation to the content from a client that is generated by;

providing the content to a user;

acquiring multiple images of the user;

extracting facial information from the user images; and

generating the emotional information corresponding to the facial information;

generating information about a representative type of emotion associated with the emotional information received from the client;

updating an Electronic Program Guide associated with the content or a header of the content using the information about the representative type of emotion; and

providing the content with the updated Electronic Program Guide or the updated header to the user so that the user can reproduce portions of the content based on the emotion.

4. An apparatus for providing content, the apparatus comprising:

a communication unit which receives emotional information in relation to the content from a client that is generated by;

providing the content to a user;

acquiring multiple images of the user;

extracting facial information from the user images; and

generating the emotional information corresponding to the facial information; and

a meta data correcting unit which reflects the emotional information to existing meta data of the content, by;

generating information about a representative type of emotion associated with the emotional information received from the client, and

updating an Electronic Program Guide associated with the content or a header of the content using the information about the representative type of emotion, wherein the content with the updated Electronic Program Guide or the updated header is provided to the user so that the user can reproduce portions of the content based on the emotion.

5. The apparatus of claim 4, wherein the communication unit transmits the content with the updated Electronic Program Guide or the updated header to a client system which requests the content.

8. A method of providing content, the method comprising:

receiving emotional information in relation to the content from a client that is generated by;

providing the content to a user;

acquiring multiple images of the user;

extracting facial information from the user images; and

generating the emotional information corresponding to the facial information;

generating information about a representative type of emotion associated with the emotional information received from the client;

updating an Electronic Program Guide associated with the content using the information about the representative type of emotion; and

providing the content with the updated Electronic Program Guide or the updated header to the user so that the user can reproduce portions of the content based on the emotion.

9. A method of providing content, the method comprising:

receiving emotional information in relation to the content from a client that is generated by;

providing the content to a user;

acquiring multiple images of the user;

extracting facial information from the user images; and

generating the emotional information corresponding to the facial information;

generating information about a representative type of emotion associated with the emotional information received from the client;

updating a header of the content using the information about the representative type of emotion; and

providing the content with the updated Electronic Program Guide or the updated header to the user so that the user can reproduce portions of the content based on the emotion.

10. An apparatus for providing content, the apparatus comprising:

a communication unit which receives emotional information in relation to the content from a client that is generated by;

providing the content to a user;

acquiring multiple images of the user;

extracting facial information from the user images; and

generating the emotional information corresponding to the facial information; and

a meta data correcting unit which reflects the emotional information to existing meta data of the content, by;

generating information about a representative type of emotion associated with the emotional information received from the client; and

updating an Electronic Program Guide associated with the content using the information about the representative type of emotion, wherein the content with the updated Electronic Program Guide is provided to the user so that the user can reproduce portions of the content based on the emotion.

11. An apparatus for providing content, the apparatus comprising:

a communication unit which receives emotional information in relation to the content from a client that is generated by;

providing the content to a user;

acquiring multiple images of the user;

extracting facial information from the user images; and

generating the emotional information corresponding to the facial information; and
