Microsoft Teams introduces AV1 codec: reducing bandwidth requirements and improving screen sharing clarity

Microsoft recently announced that their Microsoft Teams application has successfully integrated the AV1 codec. The introduction of this technology is expected to significantly reduce bandwidth requirements while providing users with a clearer screen sharing experience.

AV1 is a well-known open video coding format with efficient compression, which can significantly reduce bandwidth consumption while ensuring high-quality video streams. In a press release, Microsoft detailed the advantages of integrating AV1 encoding into Teams applications. Through A/B testing, Microsoft found that AV1 can reduce bandwidth requirements by 63% during screen sharing transmissions in Teams compared to the H.264 video codec. This means that when sharing static content, the bandwidth required is typically less than 200Kbps, and when sharing mobile content, such as when scrolling a page, the bandwidth required is only about 1.2Mbps.

As the data editor understands, this update of the Microsoft Teams application will bring two significant benefits to users. When bandwidth is limited, AV1 encoding can significantly improve the clarity of shared content, whether it is detailed spreadsheets, vivid presentations, or dynamic videos, all presented with higher definition. This will result in clearer text and more vivid images, making the meeting experience more effective and engaging. At the same time, AV1's bandwidth efficiency will also save organizations money. By reducing the amount of data required to transmit screen sharing, AV1 can alleviate network congestion and reduce demand on internal networks, thereby saving costs for enterprises. At the same time, this also means that the service is more scalable and can support a growing user base, and the reduction in data transmission volume will also reduce the load on the server.
