Set-Top-Box Lexicon: Log Rolling

CIMM is taking a pro-active role in advancing new media nomenclature and processes with both its Lexicon(terms and definitions associated with Set-Top Box data measurement) and Asset Identification Primer (glossary of asset terms). These documents form the basis of the Word-A-Week column which offers a common language for Set-Top Box nomenclature that can expedite the rollout of the data for its many industry applications.

The ability to accurately measure usage from STB data rests not just on the data but also the content and line-up logs to which the data is matched. There are generally two categories of logs: As Scheduled logs and As Run logs. Scheduling logs are created before the fact and are often used to determine which string of data correctly corresponds to a specific program or advertisement. But changes to the line-up leading up to air are sometimes not reflected in these pre-to-air logs. Did a program actually run at its anticipated scheduled? Was anything pre-empted or moved? That is why As Run Logs, which reflect the actual line-up airings after the fact, are important components in STB measurement. They offer the ability to more accurately match tuning data to the actual line-up as it really aired.
