What is 1440p?

1440p is a newer resolution of high -resolution television and high -resolution movies that refers to the image of the image itself. Number 1440 refers to the vertical resolution of the image, which points to 1440 pixels in the vertical axis. It is understood as combined with a standard 16: 9 aspect ratio on a high -resolution television, indicating a 2560 horizontal resolution. 30 years, although TVs considered high resolution, would now be considered rather low definitions. Until the sixties, when the Japanese first began experimenting with truly colorful high -resolution TVs, this high -definition television has become a real possibility. In the age of 80, technology from these Japanese TVs began to get to the United States, where they immediately took all the storms. In fact, Ronald Reagan first saw a TV with a high -rayHe said that he should be a national priority to gain high resolution in every house. FCC, however, has seen extremely high requirements of a high -resolution zone bandwidth as a technology rendering and refused to approve it.

As soon as digital technologies have reached the TV, this problem with the bandwidth has disappeared. Digital compression techniques allow images to be extremely compressed to a fraction of their size and transmitted by relatively small bandwidth. Standards began to be created, with one area of ​​timely debate with the final ratio of this new high -resolution television. Several ideas were presented and finally decided 16: 9 as a reasonable compromise between the 5: 3 ratio found on the Earlier Japanese TVs with high definition and many others and the ratio of foreigners used in most film cinemas. The original high -resolution television specification includedThe resolution of 1080i and 1080p, but did not have a resolution of 1440p or a lower 720p resolution, which was decided that there was no really high definition.

However, it was a 720p distinction that would make the first actual penetration into network television into high -resolution broadcasting. Many networks, including ABC, ESPN and FOX, use 720p as a resolution. Another predominantly used resolution, 1080i, has a higher pixel resolution, but since the picture is interleaved to save the bandwidth, it may seem a little nervous. These networks chose 720p because it is a more convenient format for things that require fast scanning, such as sports, while channels like NBC and HBO chose 1080i for their image quality.

1440p, although not widely accepted, is probably the successor of 720p. It is in many ways the same format, but with a much higher number of pixels. The resolution axes are exactly doubled, creating a four -fold increase in total pixels: 3,686 400 for 1440p unlike 921 600 for 720p. This creates a much sharper, much cleaner image and compression technology of width and improves and the bandwidth capabilities grow rapidly, the added cost of the bandwidth becomes less and less worrying.
