New Virtual Classroom Major Version - "Next-Generation" Application Build (03/16/2019)

We've rolled our a new virtual classroom build across all global locations. This new build introduces some amazing features and improves overall stability of the app.

New Features:


1) Introducing "New Enhanced Recorder"

  • New Enhanced Recorder (isRecordingLayout=1) is designed to record the entire browser tab including all the app icons and layout. Customers can choose between current standard and all-new enhanced recorder layouts for recorded videos. If isRecordingLayout=1 is not specified in the API call, default layout of isRecordingLayout=0 will be automatically assumed be the current standard recorder.

2) Improved DPI for uploaded documents

  • Improved DPI (dots per inch) offers improved quality for all your documents on the whiteboard. Documents in general with a higher DPI will look much better when compared with those of a lower DPI. Now, the documents will look amazing across all the devices.

3) Plugin free Screensharing for Chrome 70+ browsers

  • Similar to our plugin-free screen sharing with Firefox browsers, this new update introduces the same technology with Chrome browsers version 70+ and above. This offers faster and improved performance when sharing entire desktop screen, application window or Chrome tab.

5) Improved look for the stacked videos

  • Removed unnecessary black areas on the videos stacked on the right top of the application screen and increased the quality.

6) Show angle when drawing straight lines

  • Teaching maths is now lot of fun. With this new feature, you can dynamically find out the angle of a straight line. Angles are measured in degrees, written °. The maximum angle is 360°. This is the angle all the way round a point. Half of this is the angle on a straight line, which is 180°. Snip20190317_87.png

7) Text editor support

  • Introducing dynamic text editor support to select font, size and colors when writing text on the whiteboard using the 'text tool'. Snip20190317_88.png

8) Improved bandwidth usage and CPU consumption

  • Improved bandwidth consumption when switching between video conferencing, screen sharing and recording by adapting to the conditions and lowered CPU usage across all devices.

Enter Virtual Classroom 30 mins in advance as Teacher

Introducing TLS 1.3 protocol support for maximum security and performance

Starting today, BrainCert platform and services will serve requests in TLS v1.3 protocol with 0-RTT support.

What is TLS 1.3?

TLS 1.3 is the newest, fastest, and most secure version of the TLS protocol. SSL/TLS is the protocol that encrypts communication between users and your website. When web traffic is encrypted with TLS, users will see the green padlock in their browser window. By leveraging the TLS 1.3 feature, traffic to and from BrainCert platform and all service endpoints will be served over the TLS 1.3 protocol when supported by clients.

What is 0-RTT?

0-RTT is a feature that improves performance for clients who have previously connected to BrainCert. It allows the client’s first request to be sent before the TLS connection is fully established, resulting in faster connection times.

New Virtual Classroom Major Version - Performance Build (01/01/2019)

  • [IMPROVEMENT] Default video tool window size should fit the video without any dark areas on the left and right side of the recorded videos output file
  • [IMPROVEMENT] "Enhanced video recorder" feature that automatically recovers corrupted or partially recorded videos by checking the file integrity and compare the data points from the session and produce a video recording file

This tool helps to create a 'blueprint' for the session by analyzing various metrics such as compute resources available in a global datacenter, optimal network path required to achieve very low-latency, switch to dynamic SFU or MCU configuration (core technology), low bandwidth optimizations and congestion control.

Planned Accomplishment in next version (2-3 weeks from now)

  • Add expand button for media player pop-up to enlarge it in whiteboard area (similar to code editor)

Virtual Classroom - Minor Patch (11/30/2018)

A minor patch for virtual classroom has been updated to fix the following issues and improve overall performance:

  • Fix insert image issue with Firefox browser
  • Chat message window shifting upwards bug with Firefox browser
  • Low volume output in a live virtual classroom session
  • Improve the adaptive bitrate algorithm to deliver the best possible audio & video performance in low bandwidth situations
  • Improve network congestion control feature to improve overall transmission performance and stability
  • Some of the old recurring classes were using old cached DNS hostnames of the VC server clusters in multiple locations. Recent updates has forced everyone to use new backend servers automatically which is transparent to end users. However, few users running very old recurring schedule were affected and this issue has been resolved by pointing to new DNS entries without any further changes
  • Improve recording bandwidth consumption and produce complete recorded video in low bandwidth situations

'Auto select nearest datacenter region' fix and the new 'Capacity' feature in virtual classroom

The previously reported issue of all the traffic going to Dallas, TX location when using 'auto select nearest location' (isRegion=0 API call) feature is now fixed. When you schedule a live class and leave the default isRegion=0 option, it will now assign class to the nearest datacenter location and/or takes the least congestion free network path in to consideration.

Furthermore, we've improved this feature to include 'capacity' in to consideration. When you schedule a class with high number of attendees, the built-in 'capacity' tool will find the best performing servers from our cluster pool and reserve it for the class to offer the best possible performance.

Introducing Amsterdam Data Center

We're excited to announce the launch our new virtual classroom region: Amsterdam, Netherlands! This brings our datacenter coverage to 15 global locations worldwide making BrainCert the largest virtual classroom provider!

As always, we bring the same high-performance and reliable technology stack that we have developed over the years and that is in use in all our previous data centers. Our latest Amsterdam datacenter offers high performance and low latency performance to the rest of the world and provides fault tolerance to other European locations that BrainCert offers - Frankfurt, London, Milan and Paris.

Use isRegion=15 to use the new Amsterdam location.

VC issues related to 'isVideo=1' and 'auto select datacenter location' features

We are currently investigating issues related to session recording and intelligent routing to nearest datacenter feature.

1) Customers are advised NOT to use isVideo=1 parameter that concatenate multiple video files into a single video file. Due to a bug with current version, the final video is not produced in few situations. This has been fixed in the upcoming major version anticipated in 2-3 weeks.

2) "Auto select nearest datacenter location" feature is routing most of the classes to Dallas, TX location which maybe congested due to high volume of traffic. Customers are advised to manually select a datacenter location.
