A Target Rating Point (TRP) is a measure of the purchased television rating points
representing an estimate of the component of the target audience within the gross
audience. Similar to GRP (short for Gross Rating Point) it is measured as the sum
of ratings achieved by a specific media vehicle of the target audience reached by
an advertisement. For example, if an advertisement appears more than once, reaching
the entire gross audience, the TRP figure the sum of each individual GRP multiplied
by the estimated target audience in the gross audience.
In the case of a TV advertisement that is aired 5 times reaching 50% of the
gross audience with only 60% in the target audience, it would have 250 GRPs (= 5
x 50) -- ie, GRPs = reach x frequency - TRP in this case should be 60% out of 250
GRPs = 150 TRPs - this is the rating point in the target, 60% of the gross rating.
Both of these metrics are critical components to determine the marketing effectiveness
of a particular advertisement.

Television Rating Points - TRP is the criterion that indicates the popularity of
a channel or programme and this data is very useful for the advertisers Presently,
INTAM (Indian Television Audience Measurement) is the only electronic rating agency
functioning in India. INTAM uses two methodologies for calculating TRP. First is
frequency monitoring, in which 'people meters' are installed in sample homes
and these electronic gadgets continuously record data about the channel watched
by the family members. 'People meter' is a costly equipment, which is imported
from abroad. It reads the frequencies of channels, which are later, decoded into
the name of the channels and the agency prepares a national data on the basis of
its sample homes readings. But there is a drawback in the technique, as cable operators
frequently change the frequencies of the different channels before sending signals
to the homes. It may be very misleading to read a channel according to a particular
frequency even if the down linking frequency is same all over India.
Second technique is more reliable and relatively new to India. In picture
matching technique people meter continuously records a small portion of the picture
that is being watched on that particular television set. Along with this agency
also records all the channels' data in the form of small picture portion. Data
collected from the sample homes is later on matched with the main data bank to interpret
the channel name. And this way national rating is produced.
Adevertisement is Calculated on the basis 10 Sec Pulse Rate
