​
Video Display Delay

  • Streaming can introduce a delay due to buffering.
  • To reduce buffering, increase the speed ratio to 400%, which bypasses the buffer.
  • Side effect: This may cause video stuttering if the network connection is unstable.

​
Multicast vs. Unicast

​
Multicast

  • Sends one stream to multiple clients instead of creating separate streams for each viewer.
  • Reduces server/network load by avoiding duplicate data transmission.
  • Best for large-scale streaming environments.

​
Unicast

  • Each viewer receives an independent copy of the stream.
  • Uses more bandwidth than multicast.
  • Best for personalized or private streaming.

​
Considerations for Streaming

  • Streaming consumes more bandwidth than playing locally stored videos.
  • Multicasting can help reduce network usage (consult your network administrator for details).
  • If the network connection fails, the stream will stop playing.

​
Performance Optimization Tip

  • To reduce playback delay, set the speed ratio to 400%.
  • Possible side effect: If the connection is unstable, the video may stutter.
