Abstract

An image data processing apparatus includes recording means for recording contents data containing moving image data, which is encoded by a first scheme, moving image decoding means for loading the contents data recorded in the recording means and decoding the moving image data, still image encoding means for obtaining image data, which corresponds to the image to be displayed at a predetermined time, as data of a still image of image data, which is the moving image data decoded by the moving image decoding means and encoding the image data by a second scheme, and time information creating means for creating information on the time when the still image is shot based on information added to the encoded moving image data.

Claims

1. An image data processing apparatus comprising:

recording means for recording contents data containing moving image data, which is encoded by a first scheme;

moving image decoding means for loading the contents data recorded in the recording means and decoding the moving image data;

still image encoding means for obtaining image data, which corresponds to the image to be displayed at a predetermined time, as data of a still image, which is the moving image data decoded by the moving image decoding means, and encoding the image data by a second scheme; and

time information creating means for creating information on a time when the still image is shot based on information added to the encoded moving image data.

2. The image data processing apparatus according to claim 1, wherein the time information creating means creates the information on the time when the still image is shot based on the shot times of the moving images corresponding to chapters in the encoded moving image data and counter information created by dividing the play time of the moving image data by a predefined unit time.

3. The image data processing apparatus according to claim 2, further comprising moving image encoding means for encoding moving image data by the first scheme,

wherein the moving image data contained in the contents data to be recorded in the recording means is supplied as data in a DV (Digital Video) format and is encoded by the first scheme by the moving image encoding means before recorded.

4. The image data processing apparatus according to claim 1, wherein the time information creating means creates information on the time when the still image is shot based on the shot times of images in a predetermined frame of the moving images, which is multiplexed and added along with the moving image data, in the encoded moving image data, and the number of frames by which the moving image data is decoded and reproduced by the moving image decoding means.

5. The image data processing apparatus according to claim 4, wherein the moving image data contained in the contents data to be recorded in the recording means is moving image data, which is encoded by the first scheme in advance and is supplied.

6. An image data processing method comprising:

loading contents data containing moving image data encoded by a first scheme, which is recorded in recording means, and decoding the moving image data;

obtaining image data, which corresponds to the image to be displayed at a predetermined time, as data of a still image, which is the decoded moving image data;

creating time information on a time when the still image is shot based on information added to the encoded moving image data; and

encoding the obtained still image data by a second scheme along with the created time information.

7. A computer-readable program comprising:

controlling loading contents data containing moving image data encoded by a first scheme, which is recorded in recording means, and decoding the moving image data;

controlling obtaining image data, which corresponds to the image to be displayed at a predetermined time, as data of a still image, which is the decoded moving image data;

controlling creating time information on a time when the still image is shot based on information added to the encoded moving image data; and

controlling encoding the obtained still image data by a second scheme along with the created time information.

8. A recording medium recording the program according to claim 7.

9. An image data processing apparatus comprising:

a recording section recording contents data containing moving image data, which is encoded by a first scheme;

a moving image decoding section loading the contents data recorded in the recording section and decoding the moving image data;

a still image encoding section obtaining image data, which corresponds to the image to be displayed at a predetermined time, as data of a still image, which is the moving image data decoded by the moving image decoding section, and encoding the image data by a second scheme; and

a time information creating section creating information on a time when the still image is shot based on information added to the encoded moving image data.
