Benefits of Digital Migration
Digital TV will enhance viewer experience through;
Better picture quality
Digital Television Broadcasting will offer sharper; brighter picture, and reduced interference. Viewers will also enjoy improved sound quality.
Digital signals take up much less bandwith and therefore more channels can be broadcast. The Kenya Government’s Broadcasting Digital Migration Policy encourages more free-to-air channels for the diverse Kenyan population including the youth, women and farmers among others.
The Set Top Box (STB) which will be used to receive the digital signal also has the capability to interface with devices such as a cell phone, memory card or internet modem. This will provide viewers with access to many more services and information.
Better viewing pleasure
With analogue you are only able to have standard definition television . With Digital Broadcasting High definition television is possible . High Definition Television is the premium version of digital television, offering picture and sound quality which is much better than today's analog television. The reason is that it offers up to twice the vertical and horizontal resolution of a traditional analog (PAL) signal. The higher resolution picture is particularly suited to large screen television displays.
This means that the benefits of HDTV are particularly noticeable on larger screen sets and when using projection equipment. HDTV will be in widescreen format and provide cinema-quality viewing with Dolby surround sound
Electronic Program Guides (EPGs)
Electronic Programme Guides (EPGs) are a feature of digital television broadcasting that come fitted in the Set Top Box. An Electronic Program Guide (EPGs) can be used by viewers to navigate between channels, identify the currently screening program and the next program ('now and next') on each channel. More sophisticated EPGs can be used to set reminders for program viewing, provide a short synopsis of the content of programs, identify programming in advance for several days, search for programs by genre, and provide access to some enhancements among others.
Better utilization of frequencies
A digital signal carries much more data than an analogue signal. Therefore, more than one channel of television programs can be broadcast at the same time. This is known as multi-channeling. This efficient utilization of channels reduces the number of frequencies required for the broadcasting sector. The CCK is therefore able to deploy the unused frequencies for use in other services.
