How are penetration rates calculated?
All penetration rates are calculated as penetration of television households.
What's the difference between primary and total homes?
Digital homes are increasingly multiplatform so the concept of the primary set is now central to forecast methodology. The primary set refers to the primary viewing platform in the home. It is independent of the number of television sets in the household as a single set (for example an integrated digital television that also receives a pay TV service), may receive content from two separate platforms. The primary set thus refers to the primary platform or service used to view television. Data that is referred to as primary set data sums to 100 per cent of television households as only one platform or service is counted in each household regardless of how many platforms or services the household has access to.
The converse is total homes which also remains an important measure. It is, of course, still important to know the total number of digital terrestrial homes regardless of whether that home uses digital terrestrial as its main means of viewing. Total homes will often sum to more than 100 per cent of TV homes because a home with two platforms is counted twice.
Which exchange rate do you use?
All our revenue models are calculated in local currency and then converted to Euros (if applicable) and US dollars. We have standardised on the use of current exchange rates meaning the average exchange rate for the applicable year is used so that local currency in year 2005 is converted using the average rate for year 2005. Currency for year 2006 is converted using the average rate for year 2006 etc. Forecasts are converted at most recent actual full year average rate.
What period does the data cover?
Data in columns headed with a year is year-end data. Data in columns headed with a quarter is as of the end of the specified relevant calendar quarter. All quarterly data is calendarised regardless of a company's fiscal reporting timetable.
