Chapter 10 Streaming (MCU and IP VCR)

Introduction

Both the MCU and the IP VCR support streaming on RealPlayer™ or QuickTime™ via web browsers or

standalone applications. Streaming participants can watch and listen to a conference but not take active part

in it. Equally, browsers can connect to the IP VCR and play back a recording.

Configuring streaming

The MCU supports unicast streaming (a direct connection to one browser) and multicast streaming

(transmitting a single copy to more than one browser simultaneously) - see below.

Streaming on the IP VCR is always unicast; that is each browser selects a recording to watch independently.

Two or more browsers can select and play back the same recording simultaneously but each one will occupy

one port.

See the online help topics “Using streaming to view conferences” (MCU) or “Using streaming to view

recordings” (IP VCR) that explain the options streaming viewers can select. This includes the bandwidth

and viewer to be used.

Multicast streaming on the MCU

You can set up the MCU to provide unicast, multicast streaming or both.

If you set the MCU up for multicast streaming (or both unicast and multicast), there are a number of

options you may want to set such as the Media transmit IP address range. In general the defaults will work,

but if you want to change them go to

Settings > Streaming and see the online help topic “Configuring

streaming settings”.
