Abstract
Abstract For multiple moving-image recorded on a storage medium, one piece of meta-data or each of multiple pieces of meta-data recorded for a part or all of the moving-image is managed by meta-data indices. A meta-data index keeps invalidity information indicating whether a piece of meta-data is going to be invalid and validity information indicating validity of the current piece of meta-data in the same form, when operations such as editing and processing are performed on a part or all of a moving-image that is an object of a piece of meta-data. When cutting-out occurs on a section of a moving-image that is an object of a piece of meta-data and the piece of meta-data cannot be recalculated, the invalidity information is copied to the validity information. In this manner, a meta-data added to the moving-image can be adapted and be used after the moving-image is edited.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
205 words
A moving image management hardware device for recording and managing plural pieces of meta-data for a part or all of a moving-image for multiple moving-images recorded on a recording medium, comprising: a unit configured to record invalidity information indicating which one of “valid”, “invalid” and “partly valid” states will exist, with regard to each of the plural pieces of meta-data, when a part or all of a moving-image that is an object of the plural pieces of meta-data is edited; a unit configured to record validity information indicating one of “valid”, “invalid” and “partly valid” states as current validity of a piece of meta-data in the same storing form as that of the invalidity information, with regard to each of the plural pieces of meta-data; and a unit configured to attempt to recalculate the piece of meta-data in order to keep the piece of meta-data valid as much as possible, with regard to each of the plural pieces of meta-data, when a part or all of a moving-image that is an object of a piece of meta-data is edited, and to copy the invalidity information to a storage area for validity information of the piece of meta-data if the piece of meta-data cannot be recalculated.
Claim 2
Dependent Claim
205 words
A moving image management hardware device for recording and managing plural pieces of meta-data for a part or all of a moving-image for multiple moving-images recorded on a recording medium, comprising: a unit configured to record invalidity information indicating which one of “valid”, “invalid” and “partly valid” states will exist, with regard to each of the plural pieces of meta-data, when a part or all of a moving-image that is an object of the plural pieces of meta-data is edited; a unit configured to record validity information indicating one of “valid”, “invalid” and “partly valid” states as current validity of a piece of meta-data in the same storing form as that of the invalidity information, with regard to each of the plural pieces of meta-data; and a unit configured to attempt to recalculate the piece of meta-data in order to keep the piece of meta-data valid as much as possible, with regard to each of the plural pieces of meta-data, when a part or all of a moving-image that is an object of a piece of meta-data is edited, and to copy the invalidity information to a storage area for validity information of the piece of meta-data if the piece of meta-data cannot be recalculated.
Claim 3
Dependent Claim
78 words
The device according to claim 1 , further comprising a unit configured to record information on overlapping and cutting-out of a part or all of an area of a moving-image that is an object of a piece of meta-data caused by a part or all of an area on which the editing operation is performed, when an editing operation is performed on a part or all of a moving-image that is an object of the piece of meta-data.
Claim 4
Dependent Claim
61 words
The device according to claim 1 , further comprising a unit configured to record, when a part of a moving-image is cut out, information indicating if only a forward-part is cut out, only a back-part is cut out, or both a forward-part and a back-part are cut out, for a meta-data corresponding to the moving-image part of which is cut out.
Claim 5
Dependent Claim
25 words
The device according to claim 1 , further comprising a unit configured to copy the invalidity information to a storage area for the validity information.
Claim 6
Dependent Claim
214 words
A moving image management method for recording and managing plural pieces of meta-data for a part or all of a moving-image for multiple moving-images recorded on a recording medium, comprising: a step of, with regard to each of the plural pieces of meta-data, recording invalidity information indicating which one of “valid”, “invalid” and “partly valid” states will exist when a part or all of a moving-image that is an object of the plural pieces of meta-data is edited; and a step of, with regard to each of the plural pieces of meta-data, recording validity information indicating one of “valid”, “invalid” and “partly valid” states as current validity of a piece of meta-data in the same storing form as that of the invalidity information; and a step of, with regard to each of the plural pieces of meta-data, attempting to recalculate the piece of meta-data in order to keep the piece of meta-data valid as much as possible when a part of all of a moving-image that is an object of a piece of meta-data is edited, and to copy the validity information to a storage area for validity information of the piece of meta-data if the piece of meta-data cannot be recalculated, wherein the steps are performed using a moving image management hardware device.
Claim 7
Dependent Claim
214 words
A moving image management method for recording and managing plural pieces of meta-data for a part or all of a moving-image for multiple moving-images recorded on a recording medium, comprising: a step of, with regard to each of the plural pieces of meta-data, recording invalidity information indicating which one of “valid”, “invalid” and “partly valid” states will exist when a part or all of a moving-image that is an object of the plural pieces of meta-data is edited; and a step of, with regard to each of the plural pieces of meta-data, recording validity information indicating one of “valid”, “invalid” and “partly valid” states as current validity of a piece of meta-data in the same storing form as that of the invalidity information; and a step of, with regard to each of the plural pieces of meta-data, attempting to recalculate the piece of meta-data in order to keep the piece of meta-data valid as much as possible when a part of all of a moving-image that is an object of a piece of meta-data is edited, and to copy the validity information to a storage area for validity information of the piece of meta-data if the piece of meta-data cannot be recalculated, wherein the steps are performed using a moving image management hardware device.
