The Dion corporate communications platform, developed by IT holding T1, has improved video communication quality and functionality through the introduction of new codecs.
The Dion desktop application now uses the VP9 codec for video calls, which has reduced the amount of data transmitted by 35% and improved image quality by 25%. This made it possible to abandon the outdated VP8 codec and Simulcast technology. As the developers explained, previously, due to it, the user's device with the camera turned on was forced to send several copies of video streams at once, which created an excessive load on the application and the network.
The AV1 codec is used for screen sharing in the desktop application and web version, which saves bitrate compared to the VP8 codec and reduces the load on the network infrastructure by about 20% with the same image quality.
Roman Cherednikov, Director of the Dion project portfolio, emphasized:
The introduction of the VP9 codec for video calls allows us to meet less stringent network requirements, and AV1 for screen sharing, in turn, ensures the transmission of the clearest possible image with minimal load on the Internet channel.
