SA to switch on digital TV signal

[Visi_Ace]

The problem is that with the current spectrum (of frequencies) is full. They cannot add more analogue signals to the current spectrum. In order to alleviate the problem, they have decided to go digital. This means that for the same frequency they can combine 8 signals through a multiplexing technology. Although it is possible to go HD with this, it takes more "bandwidth". So they first have to convert the analogue to digital and free up spectrum and then they can convert from SD to HD. Compare this to an HDD that is full. You can then go through an excercise of zipping your files to free up space before you can put on new files. In effect you have then much more files on your HDD compared to when they were not zipped. The multiplexing of signals will also make it possible to increase the number of channels in terrestrial zones whrere thereare low "bandwidth" signals that can currently only disstribute a few channels. Furthermore, it would be possible to use a standard RGB TV. It will also be able to work through the DSTV decoders. One will only have to upgrade ones TV once the signal is HD only or if you prefer to watch HD from other sources on your TV. The signal should be better as it reduces interference and it would be possible to get clear pictures in areas where you previously had "ghost" images witht he analogue signal.
