Enhanced Browser Content Redirection (BCR) with Webex Progressive Web App (PWA)
In this article
Feedback?Enhance your Virtual Desktop Infrastructure (VDI) collaboration experience by pairing the Webex App for web with a VDI application that supports BCR, such as Omnissa Horizon. This setup eliminates the need for installing a built-in application, providing you with a seamless user experience.
BCR is a technology that virtualization providers use to improve the user experience of video technologies in VDI environments.
Enhanced BCR is optimized for use on Chromebooks, requiring ChromeOS as the local operating system and Windows as the virtual operating system. Support for other operating systems may vary depending on the virtualization providers. Install the Webex App for web (web.webex.com) as a PWA in your environment. As a PWA, it operates in a standalone window, providing functionality similar to traditional desktop applications.
