National Rentrak Live Only with Demos Surveys

National Survey Information - STRATA VIEW v2.4a
Survey	New Format TV5
	Broadcast calendar definition. Broadcast weeks M-Su definition.
	Single day, quarter hour data and program titles between 6a-6a.
	Stations may be reported as SD and HD where available. During processing, SD and HD station data are merged under the "-TV” station call letter and HD station data is reported as "-HD”.
	Stations are sorted alphabetically by call letter.
	Data delivery is monthly.
	"Rentrak” Service label will be used to indicate that the only Rentrak supplied data is for Households.
Household Data	Household Rtgs, HUTs and Populations are available from the HH Rentrak Feed.
Demo Data	Demo data is available. PUTs are not available. **See Demo PUT Methodology section below
	Demographics do not reflect viewing by individuals within a given segment. Rather, they reflect viewing by households with a member in the segment.
Projections / Averages  Support	Projections and Averages are supported.
Copyright	Rentrak Corporation Audience Estimates Copyright (c) YYYY Rentrak Corporation. Rentrak-derived minimum thresholds have not been applied to these estimates; the thresholds will be applied on a go-forward basis in a future Rentrak release. Audience estimates for total households and age/gender only are available based on market tiers.
Minimum Threshold	TBD - Rentrak will be providing minimum threshold and IFR suppression rules for demographics in the future.

STRATA Demo PUT Methodology for Rentrak Demo Data

Demos Rtgs are only provided for a subset of stations (broadcast stations) by Rentrak at this time. STRATA has decided to estimate Demo PUTs (starting with the October 2016 data) so that our users can project demo viewership.

Using only the subset of stations with reported demo ratings, we calculate the "total” reported station viewing for HH and Demo and the "total” reported station HH Shrs by day and quarter hour. Although Households have viewing and usage estimates for cable networks and broadcast stations, using the subset of stations where demo ratings exist will be a better representation of PUT levels since there are no cable demo ratings available at this time.

Based on the "total” reported stations HH Shrs, we estimate the Demo PUT for the "total” reported stations by day and quarter hour.

Total Station = set of stations that contain both HH and Demo reported viewing.

For each day and quarter hour:

Total Station HH Imps = Sum of HH Imps for stations with reported demo viewing

Total Station HH Shrs = Total Station HH Imps / HH HUT

Total Station Demo Imps = Sum of Demo Imps for stations with reported demo viewing

Demo PUT = Total Station Demo Imps / Total Station HH Shrs

Once the Demo PUTs are derived by day and quarter hour, Demo viewing estimates for any station can be expressed over the calculated Demo PUT to derive Demo Shrs.

Once Rentrak starts supplying Demo PUTs and Shrs, we will stop producing Demo PUT estimates. Depending on how Rentrak derives their Demo PUTs and Shrs, methodology can vary. The STRATA methodology for producing Demo PUTs was discussed with Rentrak.
