Methods and apparatus for loading and roll-off of reference media assets

At least one non-transitory computer readable medium comprising instructions which, when executed, cause one or more processors to at least:

• determine whether a first condition to prune a reference media asset is satisfied;
• in response to a determination that the first condition is satisfied, determine whether a second condition to prune the reference media asset is satisfied;
• in response to a determination that the second condition is satisfied:
• segment the reference media asset into a plurality of segments based on a length of the reference media asset;
• prune a first one of the segments;
• and
• retain a second one of the segments in a database to compare with meter data to credit media exposure associated with the reference media asset and;
• in response to a determination that the second condition is not satisfied:
• determine whether the reference media asset was segmented previously;
• and
• in response to a determination that the reference media asset was segmented previously, retrieve a complete version of the reference media asset from an archive, the complete version of the reference media asset including the first one of the segments previously pruned from the reference media asset.

A method comprising:

• determining, by executing an instruction with at least one processor, that a first condition to prune a reference media asset is satisfied;
• in response to a determination that the first condition is satisfied, determining, by executing an instruction with the at least one processor, that a second condition to prune the reference media asset is not satisfied;
• in response to a determination that the second condition is not satisfied:
• determining, by executing an instruction with the at least one processor, that the reference media asset was segmented previously into a plurality of segments based on a length of the reference media asset;
• and
• in response to a determination that the reference media asset was segmented previously, retrieving, by executing an instruction with the at least one processor, a complete version of the reference media asset from an archive, the complete version of the reference media asset including a first one of the segments previously pruned from the reference media asset.
