 * < **Advantages of DTV in comparison to Analogue** ||< **Disadvantages of DTV in comparison to Analogue** ||
 * < The picture is better (not grainy and disturbed) also the sound is better (clearer) ||< The procedure of transmitting television data is longer ||
 * < It is more user friendly without flipping to every single channel to see what is on and what is not we can use a listing which shows the programs running on each channel ||< You either get a very good picture or you get none at all- unlike in Analogue you can get picture even if the quality is degraded ||
 * < A larger number of channels can be transmitted over the same cable or over the air frequency this is due to the ability to be able to compress the transmission to take up less bandwidth. ||< Television sets do not have the facility to tune to these new digital waves. This problem can be solved by either buying a new generation television or else buying the digital tuner that can be attached to your normal television to provide the same effect.
