What is TRP (Television Rating Point)?

 The most important term in the media and entertainment field is Television Rating Points better known as TRP. Television Rating Points is an index which provides the details about the viewership of television channels as well as the shows telecasted on them. It helps in deciding the time-slot of the shows and also the slot for advertisements. In India TAM (Television Audience Measurement) and aMap(Audience Measurement & Analytics Limited) are the electronic rating systems for measurement of TRP.

 In case of TAM, for calculation purpose two methodologies are used one being the frequency monitoring and the other is picture matching technique. In the frequency monitoring technique ‘people meters’ are attached to the TV sets in sample homes which records the details about the channels watched by the family members at a particular point of time, their frequency of changing the channel and the maximum viewership time-slots. The ‘People meter’ reads the frequencies of channels, which are later, decoded into the name of the channels and the agency prepares a national data based on the readings from the TV sets of sample population. To determine the final TRP of a channel or its shows an average of the entire week is considered and accordingly the success of a show for the particular week is judged .

 The sample homes for the purpose of calculation are based on different geographical, demographic or SEC sectors. The numbers of ‘people meters’ sample as per the Ministry of Information and Broadcasting (MIB) has to be ramped up to 20,000.The drawback in this 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 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 records of all the channels’ data in the form of small picture portion is also collected. Data collected from the sample homes is later on matched with the main data bank to interpret the channel details and subsequently national rating is produced.

 aMap is an audience measurement system that provides data on television in India via aMap Digital. AmapDigital is an overnight DTH (Direct-to-home) TV audience measurement panel. aMap provides data on television ratings, gross rating points (GRP), reach, time spent, market share, target groups, connectivity of channels, content analysis .The sample size for this technique is 6000 metered homes.

It is the only system in India that gathers and disseminates connectivity data on an overnight basis, for three times of the day. To aMap’s subscribers, data is provided on an overnight basis by market and by band. Data is disseminated via the following bands Prime band, Colour Band, S Band, Ultra High Frequency (UHF) and Hyper Band. It gives the percentage of homes that receive a channel on a particular band. The greatest advantage of this method is that it provides data on daily basis unlike TAM which delivers on weekly basis.
