Set the Broadcast stream options

A Live Broadcasting Project supports two types of live streaming modes: Broadcast mode (also referred to as pull mode, because other sources are pulling the content from Microsoft Expression Encoder) and Publishing Point mode (also referred to as push mode, because you are pushing content to a server). This topic only covers using Broadcast mode. For more information on Publishing Point mode, see Set Publishing Point options.

When you stream using Broadcast mode, you are specifying that the host, such as a portable computer, will broadcast the stream to a local port. A remote client then initiates streaming or pulls the content from the encoder. This client could be Windows Media Player, a Microsoft Silverlight player, or a Windows Media server.

Broadcast mode is useful for the following reasons:

  • You can stream the content to a limited number of clients. You can specify the number of possible client connections, up to 50.

  • You can allow each of several distribution servers, or individual clients that connect at different times, to connect to the content at the time that they want to receive the content.

  • If a server is behind a firewall, but the encoder is set up on a public network (for example, at a conference), pulling from the encoder allows the firewalled server to keep the content protected by pulling it through a firewall and then putting the stream on a distribution server in the protected network.

To set Broadcast options

  1. In the Output panel, select Broadcast.

  2. In the Port box, type the local port to which you want to send your streaming content. A remote client then pulls the content from the encoder using the port that you specify.

  3. In the Max Connections box, type the maximum number of users that you will allow to log on to your computer. You can also drag the value to change it.

  4. Click Launch Preview to preview your broadcast in a Silverlight template. This template is for preview purposes only. You cannot save or modify it.
