Description
2357626 APPARATUS FOR RECORDING AND/OR REPRODUCING MOVING PICTURE USING
KEY FRAME AND METHOD THEREOF The present invention relates to an apparatus for recording and/or reproducing a moving picture using a key frame and a method thereof, and more particularly, to an apparatus for recording and/or reproducing a moving picture using key frames by which the overall scenario of lo moving picture contents can be ascertained during a trickplay mode, and a method thereof.
In existing moving picture recording methods, moving picture data streams are recorded on a recording medium as is they are, and in existing moving picture reproduction methods, the thus-recorded moving picture data streams are reproduced at a normal speed or at a high speed according to a given reproduction speed factor. During a normal speed reproduction mode, reproduction is performed at a normal speed. During a high speed reproduction mode, reproduction is performed at a speed of 2 times, 4 times or 6 times the normal speed.
While conventional mov-ing picture reproduction methods are performed at a fixed speerl selected from predetermined reproduction speed factors. The same problem is even encountered during a high speed reproduction mode, such as a trick-play mode. In other words, in a trick- play mode, reproduction is performed at a speed selected from 2 times normal speed, 4 times normal speed or 6 times normal speed. Thus, it is difficult to reproduce only the key frame corresponding to a user's desired representative picture based on the conventional moving picture 2 reproduction method. Accordingly, it is quite difficult for a user to accurately detect a desired scene (e.g., the title of a movie) from moving pictures reproduced at a high speed, like in a trick-play mode, and to reproduce s the same.
To overcome the above-described problem, there has been proposed a method in which, while watching moving picture contents, a user directly marks every desired scene to be reproduced, the marked scenes to be used as key frames during reproduction. However, according to this method, the user must mark every desired scene manually while watching moving picture contents. As marking is done manually, it is not easy to accurately is mark only key frames representing the overall scenario of moving pictures occurring in real-time.
With a view to solve or reduce the above problems, it is an aim of embodiments of the present invention to provide a moving picture recording apparatus for automatically recording positions of repr(sentative scenes by which the overall scenario can be estimated, from input moving picture data streams.
It is another aim of embodiments of the present invention to provide a moving picture reproducing apparatus for automatically searching for the position of a representative picture recorded by the moving picture recording apparatus and reproducing the same.
It is still another aim of embodiments of the present invention to provide a moving picture recording and/or reproducing method of automatically recording the position 3 of a representative picture by which the overall scenario can be estimated from input moving picture data streams, and reproducing only the recorded representative picture.

Preferably,. in the case where the input moving -picture data streams are coded based on MPEG coding standards, when the period pattern of intra-frames of input moving picture data streams is out of the normal intra-frame period pattern compatible with the MPEG coding standards, the key frame detection and mark unit determines that there is a scene change, and then detects the intra-frame occurring for the first time as a key frame corresponding to a representative picture.
4 According to a second aspect, there is provided a moving picture reproducing apparatus including a recording medium having coded moving picture streams and a s representative picture position detected when there is a scene change, recorded thereon, and reproducing means for searching for the representative picture position recorded on the recording medium and reproducing a. representative picture.

6 For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings in which:
Figure 1 is a functional block diagram illustrating a moving picture recording and/or reproducing apparatus using a key frame according to embodiments.of the present invention; Figure 2 is an operational flow chart illustrating a moving picture recording method using a key frame according to embodiments of the present invention; and is Figure 3 is an operational flow chart illustrating a moving picture reproducing method using a key frame according to embodiments of the present invention.
The present invention will now be described in detail 20 with reference to the accompanying drawings.
1 Referring to Figure 1, a moving picture recording and/or reproducing apparatus according to an embodiment of the present invention includes a key frame detection and mark unit 10.', a recording processor 12, a recording medium 14, a key frame position search unit 16, and a reproduction processor 18. The. key frame detection and mark unit 10 and the recording processor 12 correspond to moving picture recording means. The key frame position search unit 16 and the reproduction processor 18 correspond to moving picture reproducing means.
7 The key frame detection and mark unit 10 detects whether or not there is a scene change when coded moving picture data streams are input, based on the coding standards of the input moving picture data streams, and detects the position of a key frame corresponding to a representative picture if there is a scene change. Then, the key frame detection and mark unit 10 marks the position of the detected key frame. The coded moving picture data streams are received from a predetermined lo broadcasting channel or supplied from an external system.
For example, in the case where the input moving picture data streams are coded based on MPEG coding standards, when the period pattern of intraframes of input moving picture data streams is out of the normal intraframe period pattern compatible with the MPEG coding standards, the key frame detection and mark unit 10 determines that there is a scene change. Af ter it is determined that there is a scene change, the intra-frame occurring for the first time is detected as a key frame corresponding to a representative picture., Also, in order to indicate that the detected intra-frame is a key frame, the position of the detected intra-frame is marked.
The recording processor 12 records the moving picture data stream having the representative picture position marked therein and the position of a scene representing a scene change on the recording medium 14. Here, the position data of the key frame may be recorded in a separate area of the recording medium 14 or may be recorded together with the moving picture data streams.
8 The moving picture reproducing means, including the key frame position search unit 16 and the reproduction processor 18, searches for the position data of a representative picture recorded on the recording medium 14 s and reproduces only the representative picture. In other words, the key frame position search unit 16 searches for the position data of the key frame recorded in a separate area of the recording medium 14 or recorded with the moving picture data stream.
In the case where the current reproduction mode is a trick-play mode (or fast forward play mode) for appreciating the overall scenario, based on the key frame position data found by the key frame position search unit 16, the reproduction processor 18 reads out only the moving picture data stream corresponding to the key frame while jumping the reproduction position of the recording medium 14, and restores the- read data stream into the uncoded original picture data, to then be displayed on a screen.
Therefore, in the moving picture recording and/or reproducing apparatus according to embodiments of the present invention, a usercan conveniently ascertain the overall scenario of the moving picture contents reproduced at a high speed and can switch the high-speed reproduction mode to a normal reproduction. mode when a user's desired scene appears. Thus, since the detailed moving pictures of the desired scene can be appreciated, the user's satisfaction with the reproduction mode can be enhanced.
9 Figure 2 is an operational f low chart of a moving picture recording method using a key f rame according to embodiments of the present invention.
If the coded moving picture data streams are applied, as shown in Figure 1, in step 21, it is detected whether there is a scene change. In step 22, the position of an intra-frame occurring for the first time after the scene change is detected is detected as the position of the key frame corresponding to a representative picture. In step 23, the detected key frame position is marked to indicate that it is the position of the representative picture. In step 24, the moving picture data stream having the position of the key frame corresponding to the is representative picture marked therein is recorded on the recording medium 14.
Figure 3 is an operational f low chart of a moving picture reproducing method using a key f rame according to 2o embodiments of the present invention.
If a trick-play mode for appreciating the overall scenario of moving picture contents is set, the position of a key. frame co-rresponding to a representative picture 25 is searched for f=om the recording medium 14.. in step 31. In step 32, while skipping all the unmarked frames between key frames based on the key frame position data found in step 31, the recorded moving picture data streams are read out. In step 33, the read moving picture data streams are 30 restored into the uncoded original picture data.
As described above, when coded moving picture data streams are recorded, a key frame representing a scene change is automatically detected and the position thereof is recorded. During a trick-play mode, the recorded key frame position is searched for and only the moving picture data stream corresponding to the key frame is reproduced s at a high speed, thereby easily ascertaining the overall scenario of moving picture contents without manipulation by a user.
Also, since appreciation of the overall scenario is allowed, a user can switch the reproduction mode to a normal reproduction mode when a user's desired scene appears in the course of watching the overall scenario, thereby easily accessing the user's desired contents among moving picture data streams.
is It will be apparent to those skilled in the art from the foregoing that, while particular forms of the,invention have been illustrated and described, various modifications can be made without departing from the spirit and scope of the invention. Accordingly, it is not intended that the invention be limited, except as by the appended claims.
