YouTube joins other video streaming sites in limiting video quality to Standard Definition

Not just YouTube, other giants like Facebook, Amazon Prime, Netflix have also announced that they will lower the quality of streaming videos on their respective platforms to tackle internet congestion amidst the surge in the number of viewers due to COVID-19.

YouTube has decided to limit the streaming quality of videos on its platform to Standard Definition (SD) to ease internet traffic during the novel coronavirus, or COVID-19, pandemic.

Due to a 21-day lockdown in India and several parts of the world, employees have been directed to work from home wherever possible. For smoother access to the productive class, lowering the quality of videos for everyone would ease the load on internet bandwidth. 

Typically, YouTube limits the quality of a video based on the viewer’s internet speeds. As a part of its pre-emptive measures, YouTube will load videos in SD for a month. However, users can still opt to watch content in High Definition (HD) by manually selecting the option in settings.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
