Cisco TelePresence MCU 4200 Series

Picture takes some seconds to build up when multicasting to a PC from an MCU

Is it normal for the picture to take some seconds to build up when multicasting to a PC from a Cisco TelePresence MCU?

It is perfectly normal for the picture to form over 3 to 5 seconds. This is because keyframes are not sent out on initial connection with multicasting because the Cisco TelePresence MCU has no way of knowing when a new viewer has started to watch. Therefore, the picture builds up gradually.

This article applies to the following products:

  • Cisco TelePresence MCU 4200 / MSE 8420
  • Cisco TelePresence MCU 4500
  • Cisco TelePresence MSE 8510 blade
