What is 4K TV?
The terms “4K TV”, “4K Ultra HD”, “4K Ultra High Definition”, and “4K resolution” refer to the specific resolution of one type of high definition (HD) television. Resolution refers to very small visual elements known as pixels. Standard definition (SD) has a resolution of 480 by 540 pixels, HD has a resolution of 1280 by 720 pixels, full HD has a resolution of 1920 by 1080 pixels, quad HD has a resolution of 3840 by 2160 pixels, and 4K TV offers the greatest resolution of 4096 by 2160 pixels. A 4K TV has approximately 8 million pixels, and the “4K” in its name is in reference to the approximate horizontal pixel count of 4096. The reduced pixel size of 4K resolution is credited with 4K television’s greater picture quality.
The 4K TV entertainment experience is characterized by cinema-quality picture and crystal clear digital resolution. This type of viewing experience is fairly new to the television industry, while 4K works of digital cinematography and movie projection have previously been released. In order for manufacturers to pursue the production of a video device capable of displaying 4K resolution, a 4K camera or 4K video recorder needed to first be developed. Thus there are special 4K cameras and 4K video recorders on the market today which capture content in Ultra High Definition. In addition, the release of a 4K Blu-ray Player and 4K Blu-ray Discs is also scheduled in the coming months.
The Difference between HD and 4K Resolutions
The differences between HD and 4K resolution videos are best illustrated by a side-by-side comparison of actual image quality. A 4K Ultra HD TV has a broader range of colors and finer resolution—the combination of which result in a more lifelike and brilliantly vibrant viewing experience. Today, 4K Ultra HD TVs are available with LCD (liquid-crystal display), LED (light-emitting diode) and OLED (organic light-emitting diode) displays.
What is the innovation in 4K technology?
To better address the question of “what is 4K TV?” it is important to note the innovation behind 4K Ultra High Definition technology. In today’s highly digital age, it is possible to convert your favorite programs and movies from standard definition or high definition into 4K definition. This process, known as upconverting, has optimized many popular shows for 4K Ultra HD TVs. The increase of 4K camera manufacturing has also provided the opportunity for video content to be recorded or edited in 4K Ultra HD resolution. A 4K TV requires more bandwidth—approximately four times the amount used by standard or high definition televisions.
Another innovation of 4K television relates to advancements in 3D technology. Many Ultra HD TVs now include extensive support for 3D programming such as 3D movies and 3D TV shows. Viewers can enjoy a clearer picture and an intensified 3D entertainment experience all in the comfort of their own homes.
What will the future of 4K TV bring? Not only might cinema-quality content be available in homes around the world, but in due time, 8K TVs may also be a reality. The technology required to bring 8K televisions to the masses is currently in the works. Once produced, these 8K Ultra HD television screens would be made up of approximately 33 million pixels.
What are the benefits of Ultra High Definition?
One recognized benefit of 4K Ultra High Definition televisions is a superior home theater entertainment experience. Viewers are able to enjoy their favorite content on a big screen, right in their own home. 4K Ultra HD is rich with lifelike picture quality and the highest possible resolution available in the television industry.
To get the full benefits of 4K Ultra High Definition (4K UHD) television, you will need the following: a 4K TV, 4K movies or 4K TV shows, and a HDMI (High-Definition Multimedia Interface) cable coupled with a reliable bandwidth connection to transfer the content to your television set. When viewing 4K UHDTV digital content, it is recommended that you sit approximately 6-10 feet away from your TV set. This intimate viewing experience is optimal as there is a correlation between screen resolutions and viewing distances.
An additional advantage of 4K UHD TV is 4K streaming. Content in 4K resolution will soon be widely available to stream and download. Streaming 4K movies and TV shows in 4K Ultra HD quality is possible if broadband speeds exceed 15 megabits (Mb) per second.
If you are ready to consider the best 4K TV experience for your entertainment needs, remember that the quality, clarity and detail of the digital picture should be brilliant and your bandwidth connection speeds may need to increase. With 4K television, your favorite programming will truly come to life like never before!
