Introduction
Content added by users in the LAN zone will be ingested to all VOD servers for which they have permissions using the Add Video page. Users in the Internet zone have the Add Video page available only if they have permissions for at least one VOD server that is also in the Internet zone. Content added by LAN users is added to all configured servers that can handle the content (for example you cannot add MPEG content to a Windows Media server) and for which you have permission. The content available for viewing may also be limited by the server type. For example, Internet users will see only MPEG-4 and Windows Media content on VOD-D and VOD-WM servers respectively. LAN users however will see all content on all servers.

ETV Internet-Based Servers
ETV Portal Server supports the installation of LAN-based servers and Internet-based servers. As part of an ETV Server installation, you can configure a VOD-D or VOD-WM server (see Table 1) to run on your LAN or on the public Internet. Before server configuration, you assign a range of IP addresses that define the LAN domain, or vice versa, that define the Internet domain. Any IP address outside that range will assumed to be from an Internet source, or vice versa, from a LAN source. (See "Assign LAN/Internet Address Range" in Global Assignments on page 21.)
You can purchase an Internet-based Windows Media server from VBrick (in which case it is configured by VBrick) or you can purchase and configure it yourself using the Microsoft documentation (not recommended). You can also install a Darwin Open Source server which is fully-compatible with ETV Portal Server but is not sold or supported by VBrick. (For more about downloading, installing, and configuring a Darwin server, go to: http:// developer.apple.com/opensource/server/streaming/) As noted, ETV users can be on the Internet or on a LAN; Internet users can only access MPEG-4 and Windows Media content stored on Internet-based servers. LAN users can access all content on all servers both inside and outside the firewall. To summarize, Internet-basedservers and users are subject to the following limitations:
•Internet servers support MPEG-4 and Windows Media content only.
•Internet servers support unicast only (they do not support multicast).
•Internet ETV users can add video only to VOD servers in the Internet zone.
•Internet users can only see MPEG-4 and Windows Media content stored on Internet- based servers.
