- What is digital television broadcasting?
Digital television broadcasting is the use of the digital technology in the transmission and reception of broadcasting services. The term ‘digital’ implies using digits or numbers in the representation of the information (again sound and pictures in broadcasting). However, instead of using the electrical signal directly, the digital technology takes representative samples of the original signal and converts these samples to digits, into what becomes a digital representation of the information. This digital information is then used in the application at hand.
- What is analogue television broadcasting?
Analogue television broadcasting is the use of the analogue technology in the transmission and reception of television broadcasting services. The analogue technology has been in existence since the use of technology in different everyday applications, including in telecommunication and broadcasting. The analogue technology essentially converts information (sound and pictures in the case of broadcasting) into electrical signals which are then used by the system to convey the information, say, through modulation of frequencies for the actual transmission.
Digital broadcasting migration means the introduction of the digital broadcasting technology in the provision of broadcasting services and moving away from the use of the analogue broadcasting technology in broadcasting. This migration is driven by the benefits that are associated with the digital broadcasting technology, which have seen most countries, the world over, embarking on the process to move over to the digital broadcasting technology
