Abstract

According to the invention every asset (metadata or essence) is labelled with a unique identifier and with the last action applied to this asset.

A problem to be solved by the invention is to faclitate storage of a recording, thereby storing the essence (A/V) of a recording on one storage medium and the metadata belonging to this recording on another storage medium.

Claims

1. Method for making a consistency decision, wherein meta-data are checked automatically or electronically for consistency, characterised by the steps:

requesting search for a link for an identifier in a LogEntry, e.g. a UUID or GUID;

analysing the LogEntry whether an identifier was found;

in case no LogEntry was found;

examining a LogEntryHistory for a matching identifier;

analysing the LogEntryHistory for an identifier found;

determining whether more than one matching identifier is available;

if this is true, consistency checking for the best matching identifier based on the action item;

returning the location of the matching identifier.

2. Method according to claim 1, wherein the action items include, but are not limited to:

creating an asset;

copying an asset;

cutting the head and/or tail of an asset;

appending an asset.

3. Method according to claim 1, wherein the identifiers and the corresponding action items are stored within the structure of the LogEntry.

4. Method according to claim 1, wherein a LogEntryHistory encompasses obsolete LogEntry elements in case a copy of an A/V stream is being generated.

5. Method according to claim 1, including using a decision table that provides a control mechanism for the identifier, the LogEntry and the LogEntryHistory, wherein the decision table contains all the processes executed on the assets.

6. Apparatus for matching assets by automatically or electronically checking said assets or part of said assets for consistency, including:

means for requesting the search for a link for an identifier in a LogEntry, e.g. a UUID or GUID;

means for analysing the LogEntry whether an identifier was found, and in case no LogEntry was found for providing this information to;

examining means for examining a LogEntryHistory for a matching identifier;

means for analysing the LogEntryHistory for an identifier found;

means for determining whether more than one matching identifier is available;

means for checking, if more than one identifier was found, the consistency of the identifiers found and for selecting the best matching identifier based on the action item;

an identifier-location provider to which the location of the matching or best matching, respectively, identifier is returned.

7. Apparatus according to claim 6, wherein the action items include, but are not limited to:

creating an asset;

copying an asset;

cutting the head and/or tail of an asset;

appending an asset.

8. Apparatus according to claim 6, wherein the identifiers and the corresponding action items are stored within the structure of the LogEntry.

9. Apparatus according to claim 6, wherein a LogEntryHistory encompasses obsolete LogEntry elements in case a copy of an A/V stream is being generated.

10. Apparatus according to claim 6, including a decision table memory that provides a control mechanism for the identifier, the LogEntry and the LogEntryHistory, wherein the decision table contains all the processes executed on the assets.
