Maximum audio/video delay for peer to peer communication

Question

Is there any standard for tolerable delay in audio and video communication for web ? I have noticed delay using my WebRTC application and want to compare it with the standard (if any).

Wikipedia has mentioned following delays:

• Live audio : several hundred ms to a few seconds,
• Telephone Calls : 200ms,
• IP calls: min 20ms, max 150ms
• Computer audio: 500ms

From book "Deploying QoS for Cisco IP and Next Generation Networks: The Definitive Guide" By Vinod Joseph, Brett Chapman:

• Voice : 150ms one way
• Interactive video: 150ms (upto 200ms)
• live : 150ms
• video on demand : 150ms
• Multimedia conferencing and streaming: >400ms

Which one should i compare with ? Interactive video, Multimedia conferencing or IP calls ?

Answer 1

There is for instance several recommendations of the ITU (International Telecommunication Union):

• Y.1541: Network aspects (network delay, jitter, packet loss, etc.)
• G.114: Mouth-To-Ear delay ( < 200ms OK, > 400ms KO ) - audio only
