Better bandwidth:

• One of the main advantages is that they are more efficient when it comes to bandwidth usage than analog transmission.

• Furthermore, the image quality delivered by digital signals is more efficient when it comes to image quality.

• In fact, high definition televisions can only display images with the use of digital data.

• The digital signals are divided into 5 signal patterns which can accommodate various aspect ratios. This in turn improves the quality of the images displayed on television.

Automatic Tuning:

• Digital signals can be tuned automatically and auto selects the suitable resolution for digital television. This in turn allows television to display clearer and more detailed images.

• It also gives assurance that television will work regardless of its bandwidth capability. Multiple Reception Outlets:

• Digital broadcasting also allows television to receive television signals through various methods.

• One of the most common methods used is through a cable connection which is also known as digital cable.

• It also allows televisions to receive digital signals with the use of satellite dish.

• This also allows setting up a computer to television system which is great for entertainment.

• Some systems have USB ports that can be connected to a telephone line allowing us to contact service provider as well as do other electronic transactions.

Capability to Record Programs:

• It also allows recording television programs so that anyone can view them at their own convenient time.

• It improves the quality of images that the television displays. The digital format is also compatible with any resolutions, giving assurance that broadcasting will work regardless of the size of television screen.
