Cupertino has been mum about the purchase, but the deal reportedly closed in January, and WaveOne employees are said to have been absorbed into Apple’s machine learning groups. WaveOne’s codecs use machine learning to squeeze more picture out of less bandwidth, including optimizing for signal interruptions, so the picture doesn’t freeze or disappear, making it ideal for mobile. As Netflix and YouTube tout picture improvements, WaveOne could potentially advantage Apple TV+ and a mixed reality headset. Continue reading Apple Eyes AI Video Compression with WaveOne Acquisition

YouTube is experimenting with a higher bitrate 1080p format for Premium subscribers. The enhanced 1080p Premium reportedly provides a better viewing experience. For now, 1080p Premium is only available to a very small group. The existing 1080p HD resolution on YouTube remains unchanged, according to the company. “1080p Premium is an enhanced bitrate version of 1080p which provides more information per pixel that results in a higher quality viewing experience,” explains spokesperson Paul Pennington, clarifying “there are no changes to the existing quality offerings for 1080p (HD) resolution on YouTube.” Continue reading YouTube Testing ‘1080p Premium’ with Its Paid Subscribers

Meta Platforms says its vision for the metaverse will rely heavily on compression technology “to deliver high-quality, uninterrupted experiences for everyone.” With that in mind, it’s trained its Fundamental AI Research (FAIR) lab on developing “hypercompression” solutions. First up is EnCodec, an audio technology it says compresses at 64 kbps, with no loss in quality, and at 10 times the efficiency of MP3. The EnCodec protocol has the potential to  greatly improve the sound and reliability of speech over low-bandwidth (like when your mobile phone is only getting one bar). It also works for music.

University of Ottawa researchers have done some groundbreaking work on lenses, using nanotechnology to develop so-called metalenses that dramatically shrink down optics. But lenses still rely on space to produce images and the researchers have presented the concept of an optical “spaceplate” that propagates light for a distance much longer than the plate thickness, enabling future imaging systems to shrink even further. A spaceplate can be used to miniaturize all kinds of devices that manipulate light. “It’s a possibly revolutionary development in the field of optical science,” suggests photography and camera news site PetaPixel. Continue reading Researchers Use Nanotechnology to Shrink Optics for Devices

At CES 2020, the non-profit standards organization Bluetooth Special Interest Group announced that LE (Low Energy) Audio would be incorporated into its technology, improving a standard signal’s ability to manage and share wireless audio streams between devices — without stressing the batteries. In fact, since 2012, Bluetooth has incorporated LE features, dubbed Bluetooth Smart and BLE, to allow wearables and sensors to stay connected and minimize battery drain. But it has had no impact on wireless audio devices, which LE Audio hopes to remedy. Continue reading CES: Bluetooth SIG’s Low Energy Audio Slows Battery Drain
