Introduction
Overview
VBrick's EtherneTV Media Distribution System consists of a group of products that includes 
the EtherneTV Portal (ETV Portal Server), EtherneTV Encoders, the EtherneTV-NXG 
Video-on-Demand Server, EtherneTV Set-Top Boxes and StreamPlayer software. This 
integrated system delivers both live and on-demand audio and video over an IP-based 
infrastructure. The ETV Portal Server functions as a video portal, permitting end users to 
view live and on-demand MPEG-1, MPEG-2 and MPEG-4 and other streams on a PC, 
Macintosh, or Set-Top Box. The ETV Portal Server comes as software-only solution that can 
be installed on a Windows Server or as a pre-configured hardware/software combination.
Downloaded Components
For Windows-based PC users only, ETV Portal Server uses VBrick StreamPlayer software-
based components to decode video streams on the user desktop. The Portal Server 
downloads these components to each user machine the first time you access the Portal Server. 
No download is necessary for subsequent access. If this is a new installation, you must answer 
Yes
 to security requests to download these components. The EtherneTV Portal Server may 
require the installation of up to five components. If you check the box 
Always trust content 
from VBrick Systems Incorporated
, any required components will be automatically 
downloaded the next time they are needed. You don’t have to restart your computer.
The standard method to download these components is by using CABs. When a user 
connects to the Portal Server for the first time, the CABs are downloaded automatically to the 
user computer. In certain circumstances however, the use of CABs is not allowed or 
impracticable. In these cases, VBrick provides an 
.msi
 installer called 
VBrickComponents.msi
. This installer installs the same components and allows end-users 
who cannot use CABs to gain full Portal Server functionality. This installer is located in the 
utils
 directory under Portal Server. Go to 
Program Files\VBrick\MCS\utils
 to run this 
utility.
