Abstract

Herein disclosed are an editing apparatus, an editing method, and an editing program allowing quick editing of video data. In order to clip a section in the video data and play it to be broadcasted as a replay, receiving a request to start playback from a desired position, an in-point is set in response to the request, and an out-point is set in response to a request to finish playback. Then, other video data from the video data of a section between the in-point and the out-point is generated.

Claims

1. An editing apparatus, comprising:

playback means for playing back video data;

first setting means for setting a first reference point, in response to a request to start playback of the video data, at a position in the video data that is being played when the request is made;

second setting means for setting a second reference point, in response to a request to finish playback of the video data, at a position in the video data that is being played when the request is made; and

generating means for generating other video data from the video data of a section between the first reference point and the second reference point.

2. The editing apparatus according to claim 1, further comprising:

a resetting unit that resets the first reference point, in response to a request for resetting while the video data is being played by the playback means, at a position in the video data that is being played when the request is made, wherein

the video data generating means generates the other video data from the video data of a section between the first reference point that has been reset and the second reference point.

3. The editing apparatus according to claim 1, wherein the playback of the video data by the playback means includes variable speed playback and pausing of the playback.

4. The editing apparatus according to claim 1, further comprising:

third setting means for making a third reference point accompanying the video data being played while the video data is being played for preview playback by the playback means; and

fourth setting means for setting a fourth reference point, in response to a request for reverse playback of the video data during preview playback, at a position in the video data that is being played when the request is made, wherein

the video data generating means generates, in response to a request for setting the first and the second reference points, other video data from the video data of a section between the third reference point and the fourth reference point.

5. An editing method comprising the steps of:

setting, in response to a request to start playback of video data, a first reference point at a position in the video data at which the playback starts;

playing back, in response to the request to start playback, the video data;

setting, in response to a request to finish playback of the video data, a second reference point at a position on the video data that is being replayed when the request is made; and

generating other video data from the video data of a section between the first reference point and the second reference point.

6. The editing method according to claim 5, further comprising, between the steps of setting the first reference point and setting the second reference point, the step of:

resetting the first reference point, in response to a request for resetting the first reference point, at a position in the video data that is being played when the request is made.

7. The editing method according to claim 5, wherein

the playback of the video data in the step of playing back the video data includes variable speed playback and pausing of the playback.

8. The editing method according to claim 5, further comprising the steps of:

forward playing the video data for preview playback of the video data before the step of playing back the video data;

setting, in response to a request for reverse playback, a third reference point at a position in the video data that is being replayed when the request is made;

reverse-playing, in response to the request for reverse playback, the video data; and

generating other video data, in response to the setting of the first reference point, from the video data of a section between the first reference point and the third reference point.

9. An editing method, comprising the steps of:

forward playing video data for preview playback of the video data;

setting, in response to a request for reverse playback, a third reference point at a position on the video data that is being played when the request has been made;

reverse playing, in response to the request for reverse playback, the video data;

setting, in response to a request for setting the fourth reference point, a fourth reference point by making the fourth reference point accompany the video data that is undergoing reverse playback; and

generating other video data from the video data of a section between the third reference point and the fourth reference point.

10. An editing program executable by a computer to carry out the steps of:

setting, in response to a request to start playback of video data, a first reference point at a position on the video data at which the playback starts;

playing back, in response to the request to start playback, the video data;

setting, in response to a request to finish playback of the video data, a second reference point at a position on the video data that is being replayed when the request has been made; and

generating other video data from the video data of a section between the first reference point and the second reference point.

11. An editing program executable by a computer to carry out the steps of:

forward playing video data for preview playback of the video data;

setting a third reference point, in response to a request for reverse playback, at a position in the video data that is being replayed when the request is made;

reverse playing, in response to the request for reverse playback, the video data;

setting, in response to a request for setting the fourth reference point, a fourth reference point by making the fourth reference point accompany the video data that is undergoing reverse playback; and

generating other video data from the video data of a section between the third reference point and the fourth reference point.
