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.
