VOD System Content

1. Streaming Media Server Configuration:

In the VOD system, you must first configure a Streaming Media Server, and the client can be used for VOD. There are many streaming media servers. Here we use the built-in media player server in windows.

System Requirements: Windows2003 Server

The following is an article about the installation of the streaming media service.Article,Streaming Media Server ConstructionI will not discuss the installation of the streaming media service in detail.

Publishing a streaming media site is similar to publishing a website in IIS. Follow the system Wizard to configure the site.

2. Video Encoder

Microsoft released the 9 series encoder for Windows Media Encoder, which can be downloaded from the Microsoft website. It is mainly used to encode video files in different formats, such as wmv and ASF. In addition, screen capture can be performed to record user Screen operations and encode them into video files in WMV format. The installation of this tool is described in the Streaming Media Server SETUP document.
