[. . . ] Remember to disable multicasting by entering in the IP address of the PC to which you want to stream. For example, if you want another PC to view the stream, save the SDP file to a share folder on the local drive. The other PC can open the SDP file and the stream can be played in a Quicktime or other MPEG-4 compatible streaming player. Since MPEG-4 encoding can be CPU intensive, it is not recommend that you view the stream on the same system as the Niagara SCX encoder unless you have a very powerful system (dual-core processors or better). Doing so may overtax the host CPU, which will cause video quality degradation and encode session failure. After you have input your settings, click the Submit button at the bottom of the Web Interface page to save your settings. NOTE: If you click away to another web page without first clicking Submit, your changes will be lost. -53- Real Encoder Settings (Helix) Real (Helix) is both a storage format and a streaming format. In addition to the ability to output to a file, the Real Encoder can stream to a Helix Server. The settings for the Real Encoder include the ability to adjust parameters for connecting and streaming to the server. Broadcast Method: There are several different broadcast types for streaming Real format video to a Helix Server, set forth as follows. · · Push, Account-Based Login (Helix Server) o Account-based, push broadcasting allows you to send a stream to Helix Server version 9 or later. In this method, Niagara Pro maintains a monitoring connection to Helix Server. This connection allows it to pass a user name and password to authenticate access to the server. Helix Server uses this connection to send statistics about the broadcast stream back to Niagara Pro. Push, Password-Only Login (Helix Server) -54- · · · o Unlike account-based broadcasting, password-only broadcasting does not establish a monitoring connection. Therefore, this type of broadcasting requires less network overhead, but receives no feedback from Helix Server. This broadcast method allows you to send a live stream to Helix Server version 9 or later. However, you must set up the server as a receiver in a splitting arrangement. Push, Multicast (Helix Server) o In a multicast, Niagara Pro can deliver the same broadcast stream to any number of Helix Servers without increasing its outgoing bandwidth. The Helix Servers will need to be pre-configured for a multicast from Niagara Pro. Pull (Helix Server) o In pull broadcasting, Niagara Pro begins to generate broadcast packets as soon as you start the encoding. However, it does not deliver the broadcast stream until Helix Server requests the stream, which occurs when the first RealPlayer® user requests the broadcast. In that way, Pull broadcasting saves bandwidth between Niagara Pro and Helix Server when no one is viewing the broadcast. This broadcast method allows you to send a stream to Helix Server version 9 or later. Legacy Push (8. x, 7. x, G2) o The legacy push method is similar to the account-based push method.

Default Directory Setting NOTE: ViewCast strongly recommends you do not alter this default setting unless you understand the risk of saving your files to a directory not located on drive <D:>. If you save your files to another drive on Niagara Pro, these files could be deleted if you use the Restore to Niagara Pro Factory Defaults feature. NOTE: Only drive <D:> on the Niagara Pro has available storage to save your files. NOTE: Drives <C:>, <E:>, and <F:> are used strictly for Niagara Pro operational programs. [. . . ]
