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 parties and 500 audio parties 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. An HD video experience is ensured even with a packet loss rate as high as 50%.

• Network QoS requirements

  QoS Item	QoS Specifications
  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 the video meeting and sharing scenario, each type of terminals requires 4 Mbit/s bandwidth. The following table lists the bandwidth requirements in pure video scenarios.

  Terminal Type	Video Resolution	Frames Per Second	Bandwidth
  Mobile app	720p (1280 x 720)	20	2 Mbit/s
  PC client	720p (1280 x 720)	20	2 Mbit/s
  		30	3 Mbit/s
  Hard terminal	4CIF (704 x 576)	30	512 kbit/s
  	720p (1280 x 720)	30	1 Mbit/s
  	1080p (1920 x 1080)	30	2 Mbit/s

• SVC & AVC dual-protocol compatibility

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

Hardware Acceleration, Beautification, and Noise Reduction

• A 720p video codec for the mobile app, iOS software and hardware encoding, but with heating generated 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 packet loss rate as high as 20%, the latency is reduced to 150 ms, and the jitter is reduced to 50 ms. The mouse shape is synchronized during data sharing.

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