At Google I/O 2014 today, Google announced some forthcoming updates to its popular Chromecast streaming dongle for televisions. In addition to a new app discovery engine that will work across iOS, Android and Chrome devices, Google is cutting the Wi-Fi ties that require users to be on the same network as the Chromecast they wish to ‘cast’ to, adding a baked-in screen mirroring options, and offering a new ‘Backdrop’ feature for display customization.

Casting goes social

Presently, if you want to cast content to a Chromecast dongle, your device must be on the same Wi-Fi network the Chromecast is on. But that’s about to change, as Google announced that, soon, users will be able to cast to any Chromecast or Android TV within close proximity, no Wi-Fi connection needed.

Google said it would use ‘various technologies’ to verify that someone is, indeed, in the same room as the television they wish to cast to, but as a fallback measure, a PIN will be displayed on-screen through the Chromecast which will allow users to authenticate themselves and get casting, free of Wi-Fi bonds.

Baked-in screen mirroring for Android devices

Until now, Android device users have had to employ the use of a third-party app to mirror anything from an Android phone on a big-screen TV through the Chromecast. That app cost money, and worse, the “mirroring” it offered suffered from occasional latency and was restricted to photos, music and stored video. In other words, it wasn’t true screen mirroring.

Now, thanks to an update for Android devices expected later this year, true, real-time screen mirroring will be a reality. In a demonstration at the I/O developer conference, Google showed an Android phone’s screen mirrored in real time, stutter free. Even when the demonstrator opened up the camera app, the video feed was shown instantaneously and without hiccup. From the live demonstration, this appears to be huge coups for Google, as screen mirroring from mobile devices has, thus far, been an involved, often expensive process.

The screen mirroring feature will be introduced first to the following list of devices, with support for more Android devices coming soon.

  • HTC One M7
  • LG G2
  • LG G2 Pro
  • Nexus 4
  • Nexus 5
  • Nexus 7 (2013)
  • Nexus 10
  • Samsung Galaxy Note3
  • Samsung Galaxy S4
  • Samsung Galaxy S5

Your TV, as a picture frame

One of the chief complaints uttered by Chromecast users since the device’s introduction is that there was no easy way to control what the dongle displayed when TV wasn’t being watched. Now, with the addition of what Google is calling “Backdrop,” users will be able to stream artwork or personal photos to the television, essentially turning the television into a giant picture frame.

For personal photos to be displayed, the images will have to be stored in a Google + account. Other images, such as well-known works of art, will be available directly from Google, and categorized under different headings, such as Art, Places, Lifestyle, Weather, and News. Google has also tweaked mobile device integration so that users can use voice search to find out more about the art that is being displayed on the screen.

A better way to find Chromecast apps

Presently, finding Chromecast-compatible apps is a real chore. But Google aims to change that with a new discovery system that will work across Android, iOS, and Chrome devices. The update is highlighted by a new Chromecast app store within Google Play, where all available Chromecast apps will be searchable by category and/or through the use of filters. Google stated the new discovery engine will be available “later this year.”

Are more Chromecast apps on the way?

Google spent plenty of time discussing the Chromecast’s successes and milestones, and highlighted its increasing useage. The company also reminded developers that its Chromecast SDK (software developer kit) is completely open, prodding developers to get on board. Though Chromecast app development has been a little slow to start, perhaps seeing how widely used the device has become will be the encouragement necessary to bring some more original apps to the table. Only time will tell, but at this point it is clear that the Chromecast is no stepping-stone technology, but a device Google has clear plans on leveraging heavily going forward.

GoldenEar Speakers joins Paradigm, MartinLogan, and Anthem
GoldenEar T66

After the news last month that Bose had acquired the McIntosh Group, we have another interesting shift in the premium audio world. PML Sound International -- the parent company of storied audio brands Paradigm, MartinLogan, and Anthem -- has welcomed GoldenEar Speakers into the fold. It was just under five years ago when it was announced that GoldenEar had been bought by The Quest Group, the owner of AudioQuest and DragonFly, upon the retirement of GoldenEar co-founder Sandy Gross.

Starting January 1, GoldenEar will be known as GoldenEar Studio Inc. PML has announced the operations will pause for the month of January to ensure a smooth transition. During that time, GoldenEar orders will not be processed or fulfilled, with operations resuming on February 3. PML has also assured that "existing warranties and service support will be honored, and they will continue to receive the same level of product quality and customer service when business resumes."

Here’s how Apple’s AirPods Pro hearing assistance stacks up to professional results
Apple's hearing test in iOS 18.1.

Apple made waves when it announced that its AirPods Pro 2, when combined with iOS 18.1, could fulfill the role of OTC hearing aids. Given that OTC hearing aids can often run as much as $1,500, it seemed too good to be true that the same hearing benefits could be had for just $249 or less. Better yet, given the popularity of Apple's wireless earbuds, there's an excellent chance that those who could benefit already own them (if you live in a country where Apple's hearing aid feature has been approved).

So how good are the AirPods Pro 2 as OTC hearing aids?
