Netflix turns to AI to help mobile users enjoy better video

Netflix has found a new use for artificial intelligence: keeping your online videos from buffering, Quartz reports from Mobile World Congress in Barcelona. That may sound superficial, but it will have big implications for data use.

The usual method for encoding online video compresses it uniformly for a specific internet speed. Videos for low-bandwidth connections are more compressed, leading to grainy images. Netflix has found a way to match the compression level to the scene's content, meaning an action scene gets more bandwidth than a low-movement scene.

The wireless impact: The new trick, called Dynamic Optimizer, is aimed at viewers who are increasingly using their mobile devices to view video, especially in emerging markets like India, Japan and South Korea.

Why it matters: The improved compression algorithms will use less capacity on carriers' networks. Netflix is one of the largest drivers of internet traffic and eats up an enormous amount of bandwidth, so freeing some of that up will improve Netflix's historically tense relationship with the companies it relies on to reach consumers.

President Trump said on Saturday he is considering a "short term" quarantine of New York, New Jersey and parts of Connecticut — areas congruent with the New York metro area, the epicenter of the novel coronavirus in the U.S.

Reality check: These states have already taken steps to quarantine residents and promote social distancing to combat COVID-19. The governors of New York and New Jersey issued statewide stay-at-home orders last week, and non-essential businesses in Connecticut were ordered to close as of this Monday.

New York — the epicenter of the coronavirus outbreak in the U.S. — has moved its presidential primary to June 23, Gov. Andrew Cuomo said on Saturday.

Why it matters: 23 other states and the District of Columbia haven't held primaries yet. The White House is recommending, for now, that Americans practice social distancing and gather in groups of no more than 10 people — while many states have issued stay-at-home orders.
