Abstract
The recording medium includes a data structure having a clip stream file and a clip information file associated with the clip stream file. The clip stream file includes at least video data for a still image, and the clip information file including at least an entry point map. The entry point map includes an entry point, and the entry point provides at least an address of the still image.
Claims20
A recording medium storing an executable data structure for managing reproduction of at least one still image by a reproducing apparatus, comprising:
- a data area storing first and second clip stream files, the first clip stream file including at least video data for the at least one still image and not including audio data, the second clip stream file including at least audio data to be reproduced with the at least one still image synchronously;
- and
- a management area storing at least one playlist file, the playlist file including at least one playitem and at least one sub-playitem, the play item indicating in-point and out-point of the first clip stream file to reproduce the at least one still image, the sub-playitem indicating in-point and out-point of the second clip stream file to reproduce audio data and including first sync information indicating the playitem associated with the sub-playitem such that the at least one still image and the audio data are played in synchronization with one another,
- wherein the playitem includes first duration information indicating whether to display at least one still image for one of a finite and an infinite period of time, and the playitem includes second duration information indicating a length of time to display at least one still image when the first duration information indicates to display at least one still image for a finite period of time.

A method of recording a data structure for managing reproduction of at least one still image, comprising:
- recording first and second clip stream files and at least one playlist file on a recording medium, the first clip stream file including at least video data for the at least one still image and not including audio data, the second clip stream file including at least audio data to be reproduced with the at least one still image synchronously, the playlist file including at least one playitem and at least one sub-playitem, the playitem indicating in-point and out-point of the first clip stream file for reproducing the at least one still image, the sub-playitem indicating in-point and out-point of the second clip stream file for reproducing audio data and including first sync information indicating the playitem associated with the sub-playitem such that the at least one still image and the audio data are played in synchronization with one another,
- wherein the playitem includes a first duration information indicating whether to display at least one still image for one of a finite and an infinite period of time, and the playitem includes second duration information indicating a length of time to display at least one still image when the first duration information indicates to display at least one still image for a finite period of time.
A method of reproducing a data structure for managing reproduction of at least one still image, comprising:
- reproducing first and second clip stream files and at least one playlist file, from a recording medium, the first clip stream file including at least video data for the at least one still image and not including audio data, the second clip stream file including at least audio data being reproduced with the at least one still image synchronously, the playlist file including at least one playitem and at least one one sub-playitem, the playitem indicating in-point and out-point of the first clip stream file to reproduce the at least one still image, the sub-playitem indicating in-point and out-point of the second clip stream file to reproduce the audio data and including first sync information indicating the playitem associated with the sub-playitem such that the at least one still image and the audio data are played in synchronization with one another,
- wherein the playitem includes a first duration information indicating whether to display the at least one still image for one of a finite and an infinite period of time, and the playitem includes second duration information indicating a length of time to display at least one still image when the first duration information indicates to display at least one still image for a finite period of time.
An apparatus for recording a data structure for managing reproduction of at least one still image, comprising:
- a pick up configured to record data on a recording medium;
- and
- a controller configured to control the pick up to record first and second clip stream files and at least one playlist file, the first clip stream file including at least video data for the at least one still image and not including audio data, the second clip stream file including at least audio data to be reproduced with the at least one still image synchronously, the playlist file including at least one playitem and at least one sub-playitem, the playitem indicating in-point and out-point of the first clip stream file to reproduce the at least one still image, and the sub-playitem indicating in-point and out-point of the second clip stream file to reproduce audio data and including first sync information indicating the playitem associated with the sub-playitem such that the at least one still image images and the audio data are played in synchronization with one another,
- wherein the playitem includes a first duration information indicating whether to display the at least one still image for one of a finite and an infinite period of time, and the playitem includes second duration information indicating a length of time to display at least one still image when the first duration information indicates to display at least one still image for a finite period of time.
