While Netflix Watch Instantly movie streams are mostly useful for casual viewing, if you’re interested in the actual quality of the video provided you may have noticed a few changes recently. Chronicled in a thread on AVS Forum and reported to us by several tipsters, more than a few users have noticed their streams on 1080p-capable hardware ( PlayStation 3 , WDTV Live) no longer rock the “X-High” notification (on PS3, hit select to view more information bout your streaming details) that had previously let them know they were getting the highest quality possible. We checked with Netflix, and according to the company, it’s rolling out better encoding that improves picture quality despite using a lower bitrate. That means 1080p works even for people with slower connections, and increases detail on “textures, shadows, skies, and particularly faces.” As a result, what was previously called “X-High HD” is now being labeled a tier lower. While it wasn’t mentioned specifically, some are theorizing the move is tied into Netflix’s use of eyeIO’s video encoding tech , which it announced earlier this year, to shrink the size of streams. eyeIO claims it can chop bandwidth by more than half for a 720p stream, something we’re sure a company that’s pushing as much data as Netflix would appreciate. Still, some viewers in the thread are claiming a noticeably softer picture as a result. Check after the break for the statement from Netflix, then take some time for “research” and let us know if you’re noticing any changes in picture quality lately.

Netflix 1080p streams no longer called X-High, company credits improved encodes
Nerval’s Lobster writes “Netflix has released Hystrix, a library designed for managing interactions between distributed systems, complete with ‘fallback’ options for when those systems inevitably fail. The code for Hystrix—which Netflix tested on its own systems—can be downloaded at Github, with documentation available here, in addition to a getting-started guide and operations examples, among others. Hystrix evolved out of Netflix’s need to manage an increasing rate of calls to its APIs, and resulted in (according to the company) a ‘dramatic improvement in uptime and resilience has been achieved through its use.’ The Netflix API receives more than 1 billion incoming calls per day, which translates into several billion outgoing calls (averaging a ratio of 1:6) to dozens of underlying systems, with peaks of over 100,000 dependency requests per second. That’s according to Netflix engineer Ben Christensen, who described the incredible loads on the company’s infrastructure in a February blog posting. The vast majority of those calls serve the discovery user interfaces (UIs) of the more than 800 different devices supported by Netflix.” Read more of this story at Slashdot.
