[. . . ] 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 GoStream 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. -52- TUTORIAL: GETTING TO KNOW YOUR GOSTREAM 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, 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, GoStream maintains a monitoring connection to Helix Server. This connection allows it to pass a user name and password to -53- TUTORIAL: GETTING TO KNOW YOUR GOSTREAM · · · · authenticate access to the server. Helix Server uses this connection to send statistics about the broadcast stream back to GoStream. Push, Password-Only Login (Helix Server) 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. Please refer to Helix Server documentation for details. Push, Multicast (Helix Server) o In a multicast, GoStream 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 GoStream. Refer to your Helix Server documentation for details. Pull (Helix Server) o In pull broadcasting, GoStream 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 GoStream 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. [. . . ] Any modifications to these drives can permanently damage your system and void your warranty. The Default AV Folder is the directory that GoStream stores AV files created whenever you select the Save to File option in an encoder profile. Refer to the Save to File option under AVI, Flash, Real, and the Windows Media Encoder Properties section for information on setting an encoder profile to create an AV file. High Temperature Alert You can enable an alert if the GoStream reaches a predefined maximum temperature level. To set the level, select the drop-down menu. [. . . ]
