Your question is about comparing resolution with storage formats with some encoding standards which is not comparable at all, so let me explain step by step:
First, understand what is resolution and pixel density
Think of your TV screen as a grid, having pixels in rows and columns. Now if the resolution is 720p, that means it has 720×1280 pixels.
This further means that 720 pixels across the screen rows and 1280 pixels down the screen as columns.
Based on this resolutions are defined as Np where N is pixels across the width, and p stands for progressive scan, i.e. non-interlaced.
Standard Definition standards –
- 480p – 480 denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio (480 × 4⁄3 = 640)
- 560p – DVD quality for SD formats
High Definition standards –
- HD displays are measured in terms of the pixels going across the screen in width having an aspect ratio of 16:9
- 1080p – resolution of 1920×1080 (2.1 megapixel)
- 4K or UHD – resolution of 3840 pixels × 2160 lines(8.3 megapixels)
240p, 480p, 720p, etc. are Video Resolutions which denote the vertical resolution. However “P” does not stand for “pixels” but for “progressive”.
720p means that all 720 lines are drawn in each frame.
It is the opposite to Interlaced (denoted as “i”) where just half of the lines are drawn each frame. So the numbers give you vertical resolutions.
Most Common Video Resolutions are the following ones:
- 352 x 240 (240p) (SD)
- 480 x 360 (360p)
- 858 x 480 (480p)
- 1280 x 720 (720p) (Half HD)
- 1920 x 1080 (1080p) (Full HD)
- 3860 x 2160 (2160p) (Ultra-HD) (4K)
1080p – 1080 lines of vertical resolution i.e. 1080 pixels per horizontal line, p stands for the Progressive scan. If we consider resolution 1920×1080 resolution, there will be 1080 pixels per each of the 1920 vertical lines, giving us a total of 1920*1080 = 2073600
720p – 720 lines of vertical resolution
480p – 480 lines of vertical resolution
Blu-Ray – It is nothing but an optical disk that is capable of storing large amounts of data that are typically required for 1080p resolution files, (now even 4k which is nothing but a resolution of 4096×2160). Which is 25GB for single layer and 50GB for dual layer
The various Rips are the pirated versions compressed further to reduce their size. They are just taken from the discs and converted to the typical formats such as .avi or .mkv
1080p/720p/480p: the number represents the number of horizontal lines the video has from top to bottom while the p stands for progressive scan.
A 480p video is made up of 480 lines stacked one on top of another, with each line being 852 pixels wide – that’s what it means when people say a video’s resolution is 852×480. Accordingly, a 720p video has 720 lines that are each 1,280 pixels wide, meaning that it is more than twice as sharp as a similar 480p video and can be viewed on a much larger screen while the 1080p video has 1080 lines that are each 1920 pixels wide.
WHAT IS BLOCKCHAIN?
In recent years, blockchain has been used in many social and corporate conversations, and everyone has heard about Blockchain technology, but most populations do not really know exactly what it means. To clearly tell us that what blockchain technique really means, allows us to give a brief section about history how money transactions have evolved. Historically, whenever people used to exchange valuable items, there were middlemen whose sole purpose was to record the authenticity of both sides and build trust among them.
The use of banks and brokers has continued over time and with the emergence of digital assets such as stocks, electronic money, and intellectual property, the need for a more secure method has emerged. This is because digital assets are usually files within a computer, which are therefore weak for manipulation and theft. Thus blocked technology enables the parties to openly and transparently deal in order to ensure that the exchange is safe and efficient.
THE FUTURE & USE OF BLOCKCHAIN TECHNOLOGY
Blockchain has the ability to completely disrupt the financial industry, social media interrupted the mainstream media, or in the same way, Netflix destroyed Blockbuster movies. Blockchain has the capability to use technology in the form of a platform that provides financial services to any person in the world, including people from developing countries who may not have access to traditional banking services and they will be able to make big transactions. Can not afford the necessary rates. This technique has the potential to make major successes in almost all major industries, which are usually tampered with by large corporations.
Blockchain technology in education can be used to know the students, who really need the scholarship and who can afford it. This is because some students are getting financing except the system. This will actually be harmful to the needy students who are ending up to leave or earn a lot of debt, which makes them work almost. After all, a large number of people are hiding their heads in the sand because they have a desire to go to Blockchain but this piece of technology is definitely not going anywhere. In the near future, we will all do business using blockchains as part of our daily activities, our great grandchildren will read about money and ATM machines such as how we read about Barter trade and gold.
