Researchers use AI to banish choppy streaming videos
Nobody likes it when their binge watching is disrupted by a buffering video. While streaming sites like Netflix have offered workarounds for connectivity problems (including offline viewing and quality controls), researchers are tackling the issue head on. In August, a team from MIT CSAIL unveiled its solution: A neural network that can pick the ideal algorithms to ensure a smooth stream at the best possible quality. But, they're not alone in their quest to banish video stutters. The folks at France's EPFL university are also tapping into machine learning as part of their own method. The researchers claim their program can boost the user experience by 37 percent, while also reducing power loads by almost 20 percent.
Netflix adds data-saving quality controls to its mobile apps
Back in March, Netflix revealed that it was working on a "data saver" feature for its mobile apps. Keeping its word, the streaming service announced today that the cellular data tool that allows users to adjust video quality to save data is available in its iOS and Android apps. In fact, we're seeing the new feature in both Netflix apps here at Engadget HQ. By default, the software adjusts video quality to allow for about 3 hours of streaming per gigabyte of data. The company says that tests showed this to be the best balance of data use and quality when streaming over a cellular connection.
Plex Android app updated with remote control from mobile devices, new transcoding
While it was exciting to hear that XBMC is making its way to Android, the Plex media center has been on the platform since last year and was recently updated with a few new features. Version 2.2.0.5 of the $5 app adds the ability to accept remote control commands from any of the company's other mobile clients, so if your phone or tablet is dangling from the TV, you can still control playback or browse media without getting up. Also new is the "QuickSilver" media transcoder from the latest Plex Media Server release which we're assured we will hear more about in the future, it's currently expected to provide improved video quality, particularly on the Kindle Fire. Since the feature is still experimental you'll have to specifically enable it in the settings menu, hit the official blog for more details on how to get it running, the full changelog and newly expanded list of devices that support HTTP Live Streaming.
Poll: Have you been affected by over-compressed HD feeds?
Talk about an onslaught. Within the course of a few weeks we've seen Shaw, Rogers and Comcast all get flamed for purportedly compressing their signals to a point beyond acceptable, and as if that wasn't enough, a recent research report found that video quality issues (shocking, we know) were the primary reason for call-in complaints. All the while, Verizon is taking the chance to toot its own horn and boast about its ability to pass along HD signals sans additional tweakage. So, are you right in the middle of this firestorm? Or are you gleefully looking in from the outside with a gorgeous HD picture on your set? Give us your story below, won't you?[Image courtesy of Vidiot] %Poll-12224%
Operators select video quality issues as primary reason for complaints
We can't say we're shocked to hear it, but new data released by Symmetricom explains that cable operators have identified video quality problems as the primary reason customers call in with complaints. Potentially more disturbing, however, is the note that "only 31-percent [of carriers surveyed] said they use network monitoring tools to discover quality problems," while 61.9-percent learn of said issues via angry subscribers. As expected, these very facts are the same reasons given for high customer churn (along with high prices), and while 40-percent of respondents suggested that VOD is causing the most quality concerns today, 51.6-percent stated that HD is "expected to produce the most quality problems one year from now." Here's a tip -- stop shoving three HD channels on a single 6MHz slot, and we'd bet the quality complaints drop significantly.[Image courtesy of Donna Earl Training]
