Demand for streaming has increased because large parts of Europe are self-isolating at home due to the coronavirus outbreak. The video-streaming provider said lowering the picture quality would reduce Netflix data consumption by 25%.

But movies will still be high-definition or ultra-high definition 4K. The change will apply to the UK as well as other European countries.

Video quality

Several factors influence how much data is used when streaming a movie online.

One of them is video resolution, including whether a video is high-definition (HD) or ultra-high definition 4K.

Another is bitrate, which influences how clear and smooth videos look when streamed online. Videos with a higher bitrate tend to look less “blocky” or pixelated, but use more data.

Out of these two, Netflix says it will cut its streaming bitrates.

Customers who pay for ultra-high definition 4K movies as part of their subscription will still be able to watch 4K films.

The announcement came after a phone call with European officials.

Thierry Breton, the European Commissioner for the Internal Market, had earlier said people should “switch to standard definition when HD is not necessary”.

An hour of standard definition video uses about 1GB of data, while HD can use up to 3GB an hour.

Netflix also offers ultra-high definition 4K video for some of its programmes.

Netflix’s decision to reduce video bitrate by a quarter appears to be a compromise.

“Following the discussions between Commissioner Thierry Breton and Reed Hastings, and given the extraordinary challenges raised by the coronavirus, Netflix has decided to begin reducing bitrates across all our streams in Europe for 30 days,” the company said.

Commissioner Breton praised the “very prompt action” Netflix took just hours after the phone call, saying it would “preserve the smooth functioning of the internet during the Covid-19 crisis”.

Internet usage

Netflix has not yet said whether the bitrate reduction will be applied to other areas such as North America.

Internet usage has been heightened in the last few weeks as more people work from home and avoid going out.

Telecoms giant Vodafone reported a 50% rise in internet use in Europe earlier this week.

Facebook chief executive Mark Zuckerberg said on Wednesday that the platform was seeing “big surges” as users tried to stay connected with friends.

The social media boss said the company typically saw its largest surge in use on New Year’s Eve, but that recent demand had outpaced that.(BBC)
