Digitisation

TV signals are currently distributed in the country in analog as well as in digital and terrestrial formats. A digital format provides better picture quality & sound and other benefits leading to a better quality service. Most cable operators in the country are providing analog TV service while all DTH operators are providing a digital TV service. Digitisation means that all cable TV households would receive digital TV signals through a Set Top Box. As part of Digitisation, every cable operator will be legally bound to transmit digital signals, which can be received at the subscriber's home only through a Set Top Box, often called a STB.

A bill aimed at digitising the cable has been passed by the Central government. This bill mandates that all cable TV operators will have to transmit TV signals in an encrypted format through a digital addressable system. This will be done through the installation of Set Top Box in every cable TV home and is being carried out in four phases.

Digitisation is the process of providing cable television signals in digital rather than analog mode. This requires television signals to be routed through a digital Set Top Box to the television.

The system used to control the distribution of digital television signals is called a Conditional Access System or CAS. This ensures that only the signals chosen and paid for by a subscriber are able to be received by that subscriber.

Post implementation of Digitisation, a Set Top Box will be necessary to continue receiving signals from the service provider of your choice (Cable operator/DTH operator). The Set Top Box can be either procured from your existing cable operator or you can upgrade to a DTH operator of your choice. If you don't buy a Set Top Box before that you may not be able to continue watching cable television.

Cable operators who do not provide a Set Top Box may no longer be able to continue their service. All such cable TV homes may not be able to watch TV channels without a Set Top Box.

Before 31 March 2013 you will have to buy a Set Top Box to continue receiving cable or DTH signals on your TV in the above cities. Considering there will be likely a last minute rush which will result in hassle & complication of Set Top Box availability, delay in installation etc., it is a good idea to make the transition as early as possible. As buying a Set Top Box is inevitable, it is advisable to upgrade now to a Set Top Box and start enjoying the digital TV experience. For example, you can start enjoying the India Australia cricket series, the upcoming IPL cricket tournament or any of your favorite serials or movies in digital quality rather than postponing it.

While you have the choice of buying a Set Top Box from your cable operator, it is advisable to evaluate all the options available in the market before buying any Set Top Box.
