TRP (target rating point) PROCESS





Television Rating Point (TRP) is a tool provided to judge which  programmes are viewed the most. This gives us an index of the choice of  the people and also the popularity of a particular channel.

                    For  calculation purpose, a device is attached to the TV set in a few  thousand viewers' houses for judging purpose. These numbers are treated  as sample from the overall TV owners in different geographical and  demographic sectors.

 The device is called as People's Meter. It records  the time and the programme that a viewer watches on a particular day.  Then, the average is taken for a 30-day period which gives the  viewership status for a particular channel.

In India INTAM (Indian Television Audience  Measurement) is the electronic rating agency which does this work. INTAM  uses two methodologies for calculating TRP.

    The 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.
