Abstract

There is provided a recording/reproducing apparatus that includes an image recording unit for recording moving picture, an audio recording unit for recording audio, a reproduction information recording unit for recording in parallel, at the time of recording moving picture and audio, reproduction information of moving picture and audio, and a reproducing unit reproducing moving picture and audio based on reproduction information, wherein the reproduction information recording unit records, for each chunk of audio data, audio synchronization information for synchronizing video and audio at the time of recording the reproduction information.

Claims

1. A recording/reproducing apparatus, comprising:

an image recording unit for recording moving picture;

an audio recording unit for recording audio;

a reproduction information recording unit for recording information for reproducing said moving picture and said audio together with, at the time of recording said moving picture and said audio; and

a reproducing unit for reproducing the recorded moving picture and audio based on said reproduction information, wherein

said reproduction information recording unit records, for each chunk of audio data, audio synchronization information for synchronizing moving picture and audio, in parallel with said reproduction information at the time of recording said reproduction information.

2. A recording/reproducing apparatus according to claim 1, wherein

said reproducing unit synchronously reproduces said moving picture and said audio based on said audio synchronization information recorded for each chunk of the audio data.

3. A recording apparatus, comprising:

an image recording unit for recording moving picture;

an audio recording unit for recording audio; and

a reproduction information recording unit for recording information for reproducing said moving picture and said audio together with, at the time of recording said moving picture and said audio, wherein

said reproduction information recording unit records, for each chunk of audio data, audio synchronization information for synchronizing moving picture and audio, in parallel with said reproduction information at the time of recording said reproduction information.

4. A reproducing apparatus, comprising:

a reproducing unit for reproducing moving picture and audio based on the information for reproducing said moving picture and said audio recorded in parallel with, at the time of recording said moving picture and said audio, wherein

said reproducing unit synchronously reproduces said moving picture and said audio based on audio synchronization information contained in said reproduction information for synchronizing said moving picture and said audio recorded for each chunk of audio data.

5. A recording method, comprising:

an image recording step of recording moving picture;

an audio recording step of recording audio; and

a reproduction information recording step of recording information for reproducing said moving picture and said audio together with, at the time of recording said moving picture recorded in said image recording step and said audio recorded in said audio recording step, wherein

said reproduction information recording step records, for each chunk of audio data, audio synchronization information for synchronizing moving picture and audio, in parallel with said reproduction information at the time of recording said reproduction information.

6. A reproducing method, comprising:

a reproducing step of reproducing moving picture and audio based on the information for reproducing said moving picture and said audio recorded together with, at the time of recording said moving picture and said audio, when reproducing said moving picture and said audio, wherein

said reproducing step synchronously reproduces said moving picture and said audio based on audio synchronization information contained in said reproduction information for synchronizing said moving picture and said audio recorded in parallel with said reproduction information for each chunk of audio data.

7. A computer program for enabling a computer to execute processing that includes:

an image recording step of recording moving picture;

an audio recording step of recording audio; and

a reproduction information recording step of recording information for reproducing said moving picture and said audio together with, at the time of recording said moving picture recorded in said image recording step and said audio recorded in said audio recording step, wherein

said reproduction information recording step records, for each chunk of audio data, audio synchronization information for synchronizing moving picture and audio, in parallel with said reproduction information at the time of recording said reproduction information.

8. A computer program for enabling a computer to execute processing that includes:

a reproducing step of reproducing moving picture and audio based on the information for reproducing said moving picture and said audio recorded together with, at the time of recording said moving picture and said audio, when reproducing said moving picture and said audio, wherein

said reproducing step synchronously reproduces said moving picture and said audio based on audio synchronization information contained in said reproduction information for synchronizing said moving picture and said audio recorded in parallel with said reproduction information for each chunk of audio data.
