Embodiment 1

[0043] (1) Structure of the embodiment

[0044] Fig. 2 is a block diagram showing a video camera according to an embodiment of the present invention. It should be noted that although the camera 1 according to the present embodiment includes an audio data processing system provided corresponding to a video processing system, this audio data processing system is omitted in FIG. 2. In the camera 1, the camera section 2 acquires the imaging result as an animation according to the control of the control section 3, and outputs the image data of the imaging result to the DSP (Digital Signature Processor) of the camera.

[0045]That is, in the camera section 2, the optical block 11 is driven by the optical block driver (driver) 12 to change the aperture, zoom factor, focus, etc. to collect incident light, so that the CCD (Charge Coupled) located behind the optical block 11 An optical image of an object is formed on the imaging surface of a device (charge coupled device) solid-state imagin...

Embodiment 2

[0152] Fig. 10 is a schematic diagram showing an AV file created by a camera according to the second embodiment of the present invention compared with Fig. 1. In this embodiment, the AV file is formed by integrating stream data and representative images. That is, in the AV file, similar to the AV file described above with reference to Embodiment 1, the real data forming the audio data is grouped into a media data frame in a certain block and the media data frame used to control the reproduction of these real data A movie frame in which control information is grouped into a certain block of control information.

[0153]Here, in the same manner as the above-mentioned embodiment 1, a sample of streaming data, a representative image, and audio data are all set in the media data frame. In addition, the media data frame is composed of a series of continuous chunks such as stream data, representative images, and audio data.

[0154] On the other hand, a movie frame is formed by adding a ...

Embodiment 3

[0161] 13A and 13B are schematic diagrams illustrating setting of representative images in an AV file according to Embodiment 3 of the present invention and comparing FIG. 6. In this embodiment, the representative images are created in the display order from the start screen. That is, as shown in FIG. 13B, in this embodiment, based on the closed GOP, consecutive pictures are sequentially set as B pictures B0 and B1, I picture IDR2, B pictures B3 and B4, and I picture P5, etc., and The pictures are arranged in the encoding order for encoding, thereby creating streaming data.

[0162] In this embodiment, the image data of the representative image is created by reducing the resolution of the B picture B0, which is the start picture in the display order of the GOP before the pictures are rearranged at the time of encoding. Therefore, in this case, once the data compression of the stream data of one GOP is performed, the reproduced picture first becomes the B picture B0 corresponding t...
