Television broadcasting systems used today do not always meet the requirements of the viewer for image quality. Experts around the world work tirelessly to improve the quality of television pictures.

Step 1
Often, when viewing a television image at a close distance, a line structure is visible, sometimes color distortions and some other defects can be observed, which reduce the horizontal and vertical clarity. As a result, the clarity of the image is significantly inferior to the clarity of photographs and modern films. The search for new ways to improve the quality of the image is due precisely to these listed disadvantages.
Step 2
Back in the 80s of the last century, a digital coding standard for studio television equipment was adopted, which was a fundamentally important step forward in the field of television broadcasting. A completely new approach to the development of television systems was formed, which has yet to influence the future of television.
Step 3
Engineers are working to create advanced television systems, offering the possibility of adopting separate but interconnected multi-line standards for studio equipment, data transmission systems and playback devices. Almost all developments regarding image quality are carried out in three main directions.
Step 4
The first direction is associated with the use of the reserves of modern television systems by introducing additional analog and digital signal processing at the transmitting and receiving sides. We are talking about improved versions of existing systems, which allows you to get a higher quality image.
Step 5
The second direction is based on changing the system for transmitting a television signal over a radio channel. This helps to improve not so much the quantitative as the qualitative characteristics of the received image. The reception of the image of standard quality is ensured by a conventional receiving device, as well as by a special receiver, which gives an image of increased clarity.
Step 6
The third development option is the use of multi-line television systems with a much larger number of lines and a frame format than current standards. These multi-line systems are already called high definition or high definition television systems.
