    複数ユーザーで構成されるビデオセッションのユーザー体験を最適化する Improve the Efficiency of Your Multi-Party Video Experiences JP

    この記事はDonal Toomeyこちらで公開した記事(英語)を日本語化したものです。

    教育、社会交流、職場のコラボレーションなどのシナリオでは、誰もが会話に参加するために、複数ユーザーでも円滑に動作する優れたビデオ環境が不可欠です。その必要性や価値は明らかですが、ブラウザーやモバイルデバイス向けの、複数ユーザー対応の高性能なビデオアプリケーションの構築は困難です。構築するビデオUIは、直感的であるとともに、ユーザーが使用するデバイスやネットワークの種類を問わず優れたビデオ体験を提供する必要があります。

    2019年、Twilioはネットワーク帯域幅プロフィールAPIを導入しました。このAPIは、ユースケースに基づき帯域幅を特定の参加者に割り当てるのに役立ちます。今回Twilioでは、ネットワーク帯域幅プロフィールAPIの機能強化版をリリースしました。機能強化版では、帯域幅とCPUの両方について、複数ユーザー利用を意識した効率的なビデオアプリケーションの構築を支援します。この効率性により、ユーザーのコンピューターのファンがうるさく回転する状況がなくなり、ビデオ品質は向上し、開発者サポートの負担が軽減されます。その他のアップデート項目として、ビデオトラックのスイッチオフのきめ細かい制御や、ユニークなレイアウトの作成が可能となっています。本稿では、ネットワーク帯域幅プロフィールAPIの機能強化版を使用する利点と、その使用例をご紹介します。

    Improve the Efficiency of Your Multi-Party Video Experiences Improve the Efficiency of Your Multi-Party Video Experiences

    A good multi-party video experience is critical for education, social, and workplace collaboration use cases, so that everyone can be part of the conversation. While the value is clear, building a performant multi-party video application for a browser or mobile device is hard. You need to create a video UI that is intuitive for your users that also delivers a great experience regardless of the device and type of network they are using.

    In 2019, we introduced the Network Bandwidth Profile API to help developers allocate bandwidth to specific participants based on the use case. Today, we are delighted to introduce the new and improved Network Bandwidth Profile API to empower developers to create multi-party applications that are more efficient with both bandwidth and CPU. This efficiency prevents users' computer fans from going haywire, improves video quality, and reduces the support burden on developers. In addition, this update provides fine-grained …

    Twilio Videoがますます使いやすく〜背景画像のぼかし機能〜 Give Your Video Application an Instant Makeover with the New Virtual Background Library JP

    この記事は、プロダクト管理担当のDonal Toomeyが、こちら(英語)で執筆した記事を日本語化したものです。

    ウェブ会議の分野では、仮想背景は目新しいものではありません。主なSaaSサービスプロバイダーは、カスタム背景の挿入やぼかしの機能を提供しています。しかし、これまでは、ブラウザベースのビデオアプリケーションを開発する開発者にとって、この機能は簡単には利用できませんでした。

    今回、Twilio Video上で構築されたビデオアプリケーションに仮想背景機能を追加する、Video Processor JavaScriptライブラリが新たに利用可能になりました。仮想背景機能は、現在ChromeとEdgeブラウザで利用可能です。

    主要な機能メリット

    • リモートおよびハイブリッドコラボレーションをサポート - エンドユーザーが自宅で仕事をしていても、プロフェッショナルな外観を損なうことはありません。

    Give Your Video Application an Instant Makeover with the New Virtual Background Library Give Your Video Application an Instant Makeover with the New Virtual Background Library

    Virtual backgrounds are nothing new in the video conferencing space, with the main out-of-the-box providers offering the ability to insert custom backgrounds and/or blurring. However, historically this functionality has not been easily available to developers who build their own browser-based video applications.

    Today, this changes with the availability of a new Video Processor JavaScript library which gives developers the tools to add virtual background support to video applications built on Twilio Video. Virtual backgrounds are currently available in the Chrome and Edge browsers.

    Virtual backgrounds can be applied for a variety of use cases, such as for professionals in the financial services, healthcare, education, and customer service spaces, as well as in more playful contexts like social video applications.

    Key benefits

    • Support remote and/or hybrid collaboration: Your end users can work from home and not compromise on their professional look

    Creating memorable moments with Twilio Video Creating Memorable Moments with Twilio Video

    Humans are inherently social beings and communication is at the core of these connections. Twilio provides developers with a wide array of channels, from voice, to messaging, email, to SMS, and of course, video.

    While consumers have been gravitating towards video in social media for quite some time, organizations are now adopting video at a much higher velocity. A study by Twilio showed that the pandemic accelerated digital transformation at companies by 6 years. That same pattern is playing out with Twilio Video. While not a material portion of Twilio's business, Twilio Video has experienced a 540% year-over-year increase in weekly minutes compared to this time last year.

    This year, Twilio invested in new Video features and we’ve seen adoption by a range of customers including Telehealth, Education, and Virtual Visits. What has made our customers successful is that they’ve created customized video applications centered around user experience. …
