Technical Specifications

Ultra-Large Meeting Support

Servers are distributed across multiple locations, so there are resources capable of supporting ultra-large meetings.

  • Up to 500 video participants and 500 audio participants can join a meeting.
  • Meetings can be up to 30 hours long.
  • Meetings can be scheduled a full year in advance.

Superb Network Adaptability

No dedicated networks are required. Huawei Cloud Meeting is highly adaptable. It can dynamically adjust the audio and video quality to match the available bandwidth. A smooth video experience is ensured even with a packet loss rate as high as 50%.

  • Network quality of service (QoS) requirements

    Delay

    150 ms

    Jitter

    50 ms

    Packet loss concealment

    50% for video, 80% for voice, 50% for data, 80% for presentation audio, and 20% for presentation video (in the case of non-continuous packet loss)
  • Bandwidth requirements: In a video meeting with data sharing, each type of terminals requires 4 Mbit/s bandwidth. The following table lists the bandwidth requirements in pure video meetings.

  • Scalable Video Coding (SVC) & Advanced Video Coding (AVC) compatibility

    SVC supports flexible feed layout, and AVC has strong backwards compatibility with existing infrastructure.

Hardware Acceleration, Beautification, and Noise Reduction

  • Hard codecs of the mobile app (including hardware and software encoders of the iOS app) deliver 720p video, but with power consumption more typical of 360p content.
  • GPU acceleration reduces CPU consumption by up to 80%, ensuring smooth video on even low-end devices.
  • Video background noise is eliminated to reduce eyestrain, and your appearance can be touched up in real time.

4K Full HD Collaboration

  • 4K HD data meetings with dynamic annotations
  • Low latency and anti-network loss for remote control

    Mouse delay is less than 200 ms. Data sharing experience is not affected even with a 20% packet loss rate, 150 ms delay, and 50 ms jitter. The mouse shape is synchronized during data sharing.

  • A next-generation HD video codec provides a more accurate image and clearer text edges.
