• Nielsen Admosphere Bulgaria runs a national TV audience measurement project
• Currently both live and time-shifted TV viewing are measured and reported.
• Time-shifted TV audience = viewing a program on a TV set later after its live broadcast.
• Various types of devices and/or services enable this: PVR, HDD, IPTV, Smart TV etc.
• In Europe there are about 20 countries in which the time-shifted audience to some
extent is part of the television measurement.
• Most often time-shift up to 7 days is measured (as well as in Bulgaria and the Czech
Republic), rarely occur different maximum number of days (3, 6 or 28).
What is Timeshift viewing and how it can happen?
• Watching of some the TV stations broadcast, but later than the time of live broadcast.
• This delay can be minutes to several days.
Practically Timeshift viewing occurs in many different ways
• Using the "Timeshift" on devices (TVs, set-top boxes) with Hard Disk Drive (HDD).
• "Manual" program recording (at HHD, DVD, USB, etc.) and later watching of it.
• TV archive service usage (video library, back views...) of IPTV or cable operator.
• Using functions of Smart TV and OTT devices (HbbTV, other applications) for accessing
the TV archives.
• Using the TV set as a screen for viewing the TV program played on a computer or
How do we measure it?
Using an audiomatching technology, i.e. by comparing the audio fingerprints from
households with reference databases of the TV stations broadcast – so the methodology
is the same as with live TV audience.
This is the way it is measured in vast majority of developed European countries.
Timeshift audience is measured in all households in the panel and on all the TVs in these
7 days horizon means that we measure viewership up to the end of the 7th day following
the date of the live broadcast (remember that TV day begins and ends at 6:00 a.m.).
• i.e. we mark the TV live broadcast day as the "zero" day, then we measure viewership during „zero“ day,
first, second, ..., up to seventh day, it means we measure in 1 + 7 = 8 days.
How do we report it?
It is reported always to the time of live broadcast – important is not the time when the
viewing happened but what program was viewed (position in the live broadcast).
Data on timeshift viewing of a program (or spot) are delivered to users gradually:
• The next morning you have Timeshift viewing for „Day 0" (= VOSDAL = Viewed On Same Day As Live).
• The next morning figures for „Day 1“ are added etc.
• Complete timeshift audience data (days 0-7) are available only after 7th day from the live broadcast.
In Adwind Kite you can calculate with any subset of live + days 0-7 (defined in the
The basic indicator of Timeshift TV audience is (as with live) "rating", either as % of TV
population or thousands of viewers
• If someone watches a program in Timeshift „mode“ more than once, rating counts him more than once.
• So we work (as well as all markets) with a cumulative rating.
The total audience (live and timeshift) is defined as a sum of live and timeshift audience,
again according to usual practice.
Timeshift audience makes additional 2 %, slightly increasing
Timeshift TV as % out of live TV
Timeshift makes an additional
2 % of TV audience for 18-49.
This level is comparable to e.g.
Germany, Spain, Italy or France.
USA, UK, Ireland, Netherlands
and Scandinavian countries
exhibit much higher levels
of timeshift TV audience
(5-15 % out of live).
