Implementing SVC in WebRTC
A new technical approach can provide large-scale group WebRTC video conferencing despite WebRTC's lack of native support for Scalable Video Coding. One of the main issues with WebRTC is the lack of Scalable Video Coding (SVC) support for group video conferences. The WebRTC standard does not include SVC, and without it, a session with multiple participants--especially on a mobile platform--requires
Google’s Free Phone Manager Could Threaten a Variety of Services (Published 2009)

Google Voice is an expanded version of a service previously known as GrandCentral, a start-up th

ビデオ会議アプリはミュート中も音声を収集している？
新型コロナウイルス感染症の影響で、テレワークが一般的なビジネスシーンになった。テレワークをスムーズに進める方法の一つがビデオ会議だが、もしかするとそのビデオ会議システムはマイクをミュートにしている間も音声データの収集を行っているかもしれない。大学の研究者らが調査の結果、ビデオ会議アプリはミュート中もマイクへのアクセスを放棄しておらず、音声データの収集を行っていると指摘したのだ。 ウィスコンシン大学マディソン校(University of Wisconsin-Madison)の研究者らがこのほど、「You’re muted — or are you? Videoconferencing apps may listen even when mic is off」において、ビデオ会議アプリケーションの動作を解析し、マイクを「ミュート」に設定してもアプリがマイクへのアクセスを放棄しておらず、生の音

Google+ has made Twitter boring, here’s what Twitter should do about that
For the past few days I’ve been hanging out in Jackson Hole with a bunch of geeks and one thing I’ve noticed over and over is how boring Twitter has gotten when compared to Google+. Why has Twitter turned boring? I’ve found several areas: 1. First experience. 2. Pictures and videos. 3. Control over content distribution. 4. No API, no auto pushing of content. 5.

Modern codecs like AV1 can bring better quality video to the open web
Here’s a surprising fact: It costs money to watch video online, even on free sites like YouTube. That’s because about 4 in 5 videos on the web today rely on a patented technology called the H.264 video codec. A codec is a piece of software that shrinks large media files so they can travel quickly over the internet. In browsers, codecs decode video files so we can play them on our phones, tablets,
