  • AVB
  • RTSP/RDT
  • VNC (RFB)
  • MPEG-DASH

Trade-off Latency

vs

Reliability

Adaptivity

  • None
  • Server-side
  • Client-side

Local network only

  • Uncompressed high bandwidth

– SDI – SMPTE ST2110

  • Uncompressed video over RTP
  • Layer 2 with reserved bandwidth

– AVB

Local network only: IP based

  • RTP

– With dynamic config: RTSP/UDP

  • Security cameras

– Without: plain RTP

  • Legacy: MPEG-TS over UDP
  • Avoid NDI

just plain evil …

Lowest latency

  • SRT

– MPEG-TS transport – Guarantees order, not delivery – Tries to retransmit – Popular in TV/Broadcast world

  • RTP based
slide-11
SLIDE 11

11

RTP/UDP Based

  • MPEG-TS stream

– RIST, much less popular than SRT

  • Legacy VoIP

– SIP (or XMPP)

  • Modern video call

– WebRTC

Medium latency

  • CDN scalable
  • Pushed over TCP
  • Specialized
  • Legacy

CDN scalable

  • Client adaptive
  • Low latency MPEG-DASH
  • Low latency HLS
slide-15
SLIDE 15

Pushed over TCP

  • Security camera

– RTSP/TCP

  • Upload to live cloud streaming

– RTMP (but consider SRT is available)

  • Internet Radio

– HTTP Streaming / Icecast

Specialized

  • Desktop sharing

– VNC (RFB)

Legacy interop

  • RealPlayer

– RTSP / RDT

  • Microsoft players

– MMS
