Abstract

According to one embodiment, an authoring apparatus configured to generate writing data to be stored in an optical disc from a video content data, includes an indexing processor configured to generate face image indexing information includes face images extracted from the video content data and time stamp information representing a time point at which each extracted face image appears in the video content data, a setting module configured to set segments along with a time axis in the video content data, wherein a number of the segments is not larger than a number of chapters being able to be set in the writing data, and a generation module configured to generate menu screen data for displaying a menu screen displaying buttons on a display screen, the buttons on which face images are displayed respectively and for jumping to the segments in which the face images appearing.

Claims

1. An authoring apparatus configured to generate data from a video content data, the data to be stored in an optical disc, comprising:

an indexing processor configured to generate face image indexing information comprising face images in the video content data and time stamp information indicative of a time when each face image appears in the video content data;

a segment alignment module configured to align segments in a time-line in the video content data, wherein a number of the segments is equal to or smaller than a predetermined number of chapters;

a selection module configured to select a single face image from the face images in each segment based on the face image indexing information for each segment;

a menu screen generator configured to generate menu screen data comprising buttons on a display screen, the buttons comprising the selected face images and to navigate to the segments comprising the selected face images; and

a data generator configured to generate the data comprising information of the video content data, the generated menu screen data, and navigation information to each segment based on the time stamp information.

2. The apparatus of claim 1, wherein the selection module is configured to select a face image appearing in the beginning of the video content data or a thumbnail image of an image in the beginning of the video content data, and to select a face image appearing in the beginning or the end of a segment comprising the end of the video content data.

3. The apparatus of claim 1, wherein the selection module is configured to select images other than a face image appearing within a predetermined time from the beginning of the segment and a face image appearing within a predetermined time from the end of the segment.

4. The device of claim 1, further comprising:

an optical disc device configured to write the data in the optical disc.

5. The apparatus of claim 1, wherein

a number of buttons simultaneously displayed in the menu screen on the display screen is equal to or smaller than a predetermined number.

6. The apparatus of claim 1, wherein

the selection module is configured to select a thumbnail image of an image in substantially the middle of the segment when no face image appears within the segment.

7. An authoring method of generating data from video content data, the data to be stored in an optical disc, comprising:

generating face image indexing information comprising face images in the video content data and time stamp information indicative of a time when each face image appears in the video content data;

aligning segments in the video content data in a time-line in the video content data, a number of segments is equal to or smaller than a number of chapters;

selecting a single face image from the face images in each segment based on the face image indexing information for each segment;

generating menu screen data comprising buttons on a display screen, the buttons comprising the selected face images and to navigate the segments comprising the selected face image; and

generating the data comprising the information of the video content data, the generated menu screen data, and navigation information to each segment based on the time stamp information.

8. The method of claim 7, further comprising:

selecting a face image appearing in the beginning of the video content or a thumbnail image in a screen in the beginning of the video content; and

selecting a face image appearing in the beginning of the segment comprising the end of the video content data or a thumbnail image of an image in the beginning of a segment comprising the end of the video content data.

9. The method of claim 7, further comprising:

selecting images other than a face image appearing within a predetermined time from the beginning of the segment and a face image appearing within a predetermined time from the end of the segment.

10. The method of claim 7, further comprising:

selecting a thumbnail image of an image in substantially the middle of the segment when no face image appears within the segment.
