Netflix goes the extra mile for mobile viewing

Netflix has its own cell towers. Netflix wants to test its app running on mobile devices under a variety of conditions available around the world, so the company decided to bring the operating equipment of six cell towers to its Los Gatos offices. “Minus the towers,” quipped Scott Ryder, the company’s director of mobile streaming.

...Each of these boxes can house dozens of devices, and emulate certain mobile or Wi-Fi conditions. “We can make a box look like India, we can make a box look like the Netherlands,” Ryder said. Altogether, Netflix runs over 125,000 tests in its mobile lab every single day.

...Netflix just re-encoded its entire catalog, again. To optimize videos for mobile viewing, Netflix recently re-encoded its entire catalog on a per-scene basis. “We segment the videos into shots, we analyze the video per shot,” said the company’s director of video algorithms Anne Aaron.

Now, an action scene in a show may stream at a higher bit rate than a scene featuring a slow monologue — and users with limited bandwidth are set to save a lot of data. A few years back, 4 GB of mobile data would get you just about 10 hours of Netflix video, said Aaron. Now, members can watch up to 26 hours while consuming the same amount of data.

I know, CSB, but it is kind of cool. Not that they would do it, but that they've been able to stretch the bandwidth so much further.
