Set-Top-Box Lexicon: Every Second Counts in Measurement
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.
In the last couple of weeks we explored measurement terms that were common to both the current measurement marketplace and the STB and Addressable arenas. The advantages of STB data include the ability to create finer measurement metrics than average minute. Here are some examples of standard measurements that have been modified to reflect more granular STB language and measurement ability:
