Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.(Science Trek music) JOAN CARTAN-HANSEN, HOST: In order to get streaming video to your device, sometimes the video has to be compressed.
A video stream is broken up into frames or bits of data.
All of the information needed for the picture is sent in the first frame.
But in the next frame, the only information sent is what has actually changed.
Say, the arm moved, but everything else stayed the same.
By not sending all the information on each frame, the file carrying that information can be smaller.
That's called compression.
So, why would you want a file to be smaller or compressed?
Streaming video that goes from the provider to your device, like your phone, goes over some kind of connection.
It could be a cellular connection or over WIFI.
If a file is too big, it can't load properly, and you get buffering.
Say, your connection isn't fast enough or large enough to keep up with the streaming file.
Your device will stop until the data catches up and then play the video properly.
So, by compressing video, your provider can send a large amount of data efficiently to your device.
