In addition, the I-picture data chunk size is 32 kbytes.
DM_PCK is appropriately added to this data block so that it is several times larger.
Can be added. A still image is formed by adding DM_PCK.
ECC block for all I-picture data block sizes
When matched to the unit (integer multiple of 32k bytes)
Benefits. For example, a plurality of sheets are continuously recorded on the medium shown in FIG.
Replacing a part of the selected still image group with another still image
(Or delete) the replacement part (erase
The still image (I-picture) of the last part is the same as the original still image.
Even if the noise is different, it becomes the ECC block unit.
Of the part that is not replaced (the part that is not deleted)
The ECC block unit of the I-picture is not broken. For this reason, a part of the still image group is later transferred to another static image.
Even if it is replaced (or erased) with a still image, it will not be replaced.
ECC code of I-picture of part (part not to be erased)
There is no need to redo. This ECC coordination
The operation of the RTR recorder is as much as it is unnecessary to redo
Since it is faster, editing still images after recording (some still images
Replacement, deletion, etc.) can be performed smoothly. However, the size of the still image to be replaced is the original size.
If it is larger than the still image size, the size of the still image to be replaced
A part of the data is moved to another recording location and recorded. Tsuma

Describe the relevant parts together. A] 1 VOB or 1 PTT has a plurality of
Still image information can be included. B] When recording a plurality of still images, 1 VOB
Has at least two pieces of still image information continuously in the empty area.
Can be recorded. [0408] c] Consecutive multiple sheets with cell information (S_CI)
Still image information can be specified. The effects of a) to c) above are the same for each embodiment.
It is communication. In other words, what is a high-performance digital camera?
1,000 or tens of thousands of still images can be recorded. Data on optical disc
Group data for multiple sheets.
Recording on an optical disc will make the process easier,
Transfer time is short. [0411] Thousands of high-performance digital cameras
Tens of thousands of still images can be recorded. Each still image
If VOB is configured and VOB information is created, management information
The news becomes enormous. Management information is greatly increased by the method of the present invention.
Can be reduced. [0412] Furthermore, with a digital camera, each sheet is stationary.
Since the image information is in separate files,
It was complicated. Grouping multiple sheets with this invention
Therefore, management and search are facilitated. [0413] Also, in the digital camera, each still image
Since the information is in separate files, one file at a time
The still image contents could not be confirmed without opening the file. This

Seamless (continuous connection between still images)
Is possible. [0420] Further, the V on which the still image itself is recorded.
_PCK and the top address of A_PCK where audio information is recorded
Since the images are listed separately, only the still image information
If you want to play only audio information,
It becomes easy. As a result, audio information in a specific VOB is mapped.
When using a still image for another VOB
Seamless display (only information can be accessed at high speed)
Is possible. F] Target specified by cell information (S_CI)
Objects are individual still images in the VOB. Therefore, the individual still images themselves during playback
Can be specified (VOBU map or VOB map
Can be accessed at high speed, and multiple still images can be sequentially
Seamless display is possible when displaying. [0423] Also, during playback, each still image itself is pointed to.
As shown in FIG.
