In the period of quarantine applications, video calling have become a must-have for staying in touch with our friends, family and other loved ones. Among all the options, one of the most popularity has earned it the Google Duo, continues to improve at a rapid pace.
If few days ago we knew they had increased the limit of users for video 12, today we know other big news, is that now the calls are going to spend less on mobile data. How much? Why?
Google adopts the best codec in the industry to use less data
It is possible that you are not what you’ve raised, but the inner workings of a video call is extremely complex. Don’t speak of the simple fact that the camera captures the video and send it by internet, but in how it must design infrastructures to support millions of calls simultaneously.
Of all the activities we do on the internet, the streaming video is more data to consume. In the case of the video consumption increases even more, having to send and receive video simultaneously.
To solve this there is a compression that is applied by the codec, algorithms that are responsible for encoding and decoding videos. While best is a codec, the higher quality it is able to keep up with a lower consumption of data.
One of the codecs latest in the industry is the codec AV1, a codec supported by the majority of technology companies and which, after several years after its launch, is starting to implement. This codec was already intoducido for Netflix to maintain the same quality eating a lot less data.
In the Google data, the difference in quality, taking a bandwidth of 30 Kbps is abysmal, which means that from now on, the video of this service will begin to spend much less data.
On the other hand, we also have a new function to take a picture during the video call. It is not a feature disruptive, but would be appreciated.
The entry Google Duo dramatically improve your consumption of data and a new function appears first in Android Free.
