Why the digital switch was better ?
If there’s one device that has played a prominent role in entertaining people it has to be the television. The esteemed T.V. has always kept us entertained; with favourite cartoon shows for the kids, ‘Whodunit’ for the budding teens, blockbusters for the young adults and the old classics of the elderly. The television has a special place in the hearts of many young adults and senior citizens of today’s generation, as it was a major source of entertainment and pastime for them when the Internet was just starting to establish itself.
However, through the ages, the television and the way of broadcasting TV shows has gone through some fundamental changes. The most noticeable change seen in recent times is the switch from analogue to digital TV. The advent of the digital age has ushered in a lot of changes in our lives and in the world of broadcasting as well. In October 2012, the switching from older analogue signal systems to newer digital systems was completed in the United Kingdom. This article will attempt to look through the reasons why this change was necessary and the implications that this has had on our viewing experiences as consumers of television.
Television, As We Knew It!
Previously broadcasting used to be analogue in nature. This meant that the TV signals were sent and received over the air, using the UHF band of Radio Frequency Spectrum (UHF stands for Ultra High Frequency). There were several issues with using analogue systems, and it soon became necessary to make the switch to digital. For instance, analogue signals did not efficiently utilise the UHF band.
Advent of the Digital Age
Digital signal systems have helped a lot to solve the problems faced by the analogue system. With digital signals, it is now possible to squeeze multiple channels into the same frequency band. This process of cleverly broadcasting a number of channels into a single block is called multiplexing. Today, there are over 50 free-to-view channels available in the digital broadcasts, and they together make up the ‘Freeview’ set of channels. These are becoming increasingly popular, with the majority of household now containing free to air tv, with a variety of channels for viewing.
There are several advantages of going digital. With the digital TV, customers get some features that just can’t be beaten:
Better Quality: With digital signals, the quality of the video and audio broadcasts improves considerably. With digital TV, streaming of HD (High Definition) content becomes an amazing possibility.
More Channels: Using digital signals allows for more number of channels to be broadcast over a single block of frequency. This translates to more channels and more entertainment for viewers.
Interactive TV: Digital TV allows incorporating interactive programming, which translates to a better entertainment experience for the viewers.
Electronic Programme Guides: Being able to get more info about what’s currently on air and what is to come is another nifty feature that viewers today enjoy with the digital TV.
