Currently, tv signals are sent via analog, digital and terrestrial formats. the digital format offers better picture and better sound, is interactive and has a whole host of benefits that make it better than cable services.the digitalisation bill will mandate that all tv will be digitally transmitted, and that subscribers will need a digital set top box to watch television. cable operators use analog formats and this will no longer be supported.

Through the digitalisation bill, the central government aims to switch the entire cable industry from analog to digital format by the 31st of december, 2014. the bill requires that any tv operators transmit encrypted tv signals through a system that is digitally addressable. that is what the digital set top box is for.

Digitalisation means that television signals are now digital, instead of analog. a digital set top box will be needed to use digital signals.
The system that distributes digital television signals is called a conditional access system or cas. this ensures that only what is paid for can be accessed by a subscriber.

The digital format provides better picture and sound quality, as well as an enhanced viewing experience with hd. it also includes interactive services like video on demand, and the freedom to pay only for the channels you choose from our extensive bouquet.

After digitalisation kicks in, a digital set top box will be necessary to decode the encrypted digital signals that all operators must broadcast by law.

Cable operators who do not provide a digital set top box will not be permitted to continue their service. after digitalisation occurs, everyone must have a digital set top box to watch television.
