Chapter 1
Using the ETV Portal Server
Introduction
The VBrick EtherneTV Portal Server is a web-based portal for accessing Live and On-
Demand audio and video files. A key component of VBrick’s EtherneTV Media Distribution
System, the ETV Portal Server provides a simple interface to easily locate available media
assets from Windows PCs, Apple Macintoshes, and Set Top Boxes. Upon accessing the main
portal page, users can navigate or search for specific videos, select the video, and immediately
begin viewing television quality video. For on-demand videos, users can Fast Forward/
Rewind and Seek to specific points in the video. Details on the specific functionality are
included later in this document.
The EtherneTV Portal Server can be accessed by Windows-base PCs, Macintoshes, or by the
EtherneTV Set Top Box (STB). For the most part, the operation of the Portal Server is the
same from a Windows-based PC, an Apple Macintosh (see note below), or an STB but there
are some subtle differences. The majority of this document is written from a PC perspective,
so certain screen shots may be slightly different for Macintoshes or STBs. For example, the
Macintosh client uses QuickTime Player to display the video, so the player window will look
different from the screen shots provided here.
Topics in this chapter
Introduction
Watch Live Broadcasts
Browse Video Library
Scheduled Programs
Menu Commands
Desktop Requirements
Note For Macintosh users, the ETV Portal Server uses the QuickTime player to display
the video. The QuickTime player supports MPEG-4 video; therefore Macintosh
users can only view MPEG-4 video. MPEG-1 and MPEG-2 videos on the system
will not display for Macintosh users.
Note The user interface in the ETV Portal Server is designed for viewing at a screen
resolution of 800 x 600 or 1024 x 768. Screen resolutions lower or higher than this
may not display appropriately.

Downloaded Components
For Windows-based PC users only, the ETV Portal Server uses VBrick StreamPlayer
software-based components to decode video streams on the desktop. ETV Portal Server
downloads these components to your machine the first time you access the server. No
download is necessary for subsequent access. If this is a new installation, you must answer
Yes to security requests to download components. The ETV 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.
ETV Portal Server Home Page
The ETV Portal Server Home page is automatically displayed when you login with a valid
Username and Password. Depending on your user privileges, all ETV Portal Server
functionality and commands are available from this page.
TTo launch the ETV Portal Server Home Page:
1. Open an Internet Explorer browser. (ETV Portal Server supports Internet Explorer 5.5
and above. No other browsers are supported.)
2. Enter the ETV Portal Server hostname or IP address (e.g. http:// mcsservername) in
the address bar to display the following window.

Watch Live Broadcasts
The Watch Television page lets you view live streams (for example, TV channels) available on
the network. The list of available streams is determined by the VBrick or other encoders in
your network. The administrator can assign a channel number to a live video stream in the
administration section. The channel appears as a number in a column to the left of each live
stream. To launch a live broadcast, simply click on any live channel and it will launch in the
Preview Window.

Customizing Live Channels
Live streams can only be customized by administrators. (See the ETV Portal Server
Administrator Guide for details). Live streams that have been customized will have an Info
button that displays additional information about the stream. For example it may have a
description or keywords that can be used for searching, as well as links to external web sites
and desktop files. You must have the appropriate application installed locally, for example
PowerPoint, in order to open a PowerPoint presentation.
Note Users cannot customize live channels. Administrators can customize live channels by
changing the name, channel number, keywords, etc. Live channels are broadcast by
VBricks and auto-discovered by the Portal Server. They cannot be added or
removed except at the VBrick layer using the IWS (Integrated Web Server)
program.

Browse Video Library
If the ETV Portal Server installation includes an EtherneTV-VOD Video on Demand server, the
Video on Demand link on the Home Page displays a list of content stored in folders and files on
the server. Note that you will only see those folders for which you have been given permission. To
launch a stored video, simply click on any video and it will launch in the Preview Window.

of the clip (see Create Thumbnail on page 14), as well as information about the
clip such as duration and keywords.

lets you move up one folder level.
Scroll Up/Down The scroll bar on the right of the table of available videos allows the user to scroll
up or down through the entries. Users can also scroll up or down through the
entries by using a mouse wheel or standard keyboard keys such as Page Up and

Emergency Broadcast
An emergency broadcast is a scheduled event that can be executed by ETV Portal Server
users with appropriate permissions. It broadcasts a live or stored video to specified VBricks
or STBs in case of an emergency. The broadcast is launched instantly, for a specified duration,
and preempts all other broadcasts. When done (or manually stopped) all preempted schedules
automatically resume. Emergency broadcast templates are pre-defined in advance by
administrators. See the ETV Portal Server Administrator Guide for more information.
TTo launch an emergency broadcast:
1. Go to MENU > Emergency Broadcast.
2. Select a template name.
3. Enter a Duration in minutes (or click No Limit).
4. Click Start Emergency Broadcast and confirm. (A message will indicate the broadcast is
in progress. Any stream currently in progress will be preempted and replaced by the
emergency broadcast.) When done, click Stop Emergency Broadcast.

You can create thumbnails only for videos stored on a VOD server. If given permission, you have
the ability to replace the generic video clip icon with a snapshot of the video or any image you
choose. The folders to which you can upload thumbnails are configured by an ETV Portal
Server administer. Note that thumbnail images created for VoD servers that exceed 512 K in
size are not displayed in the VoD list on a Set Top Box. A special icon is used instead.

Add Video
If given permission, you have the ability to Add Video to the EtherneTV-VOD Video-on-
Demand server. The folders to which you can Add Video to are configured by your
Administrator. The folder list that you can Add Video to may be different from the folders
from which you may view content. If you have an MPEG-1, 2, 4 or WM video saved on your
PC (which may be acquired by recording with StreamPlayer Plus or a VBrick VBStar), then
you can publish this to the on-demand server by using the Add Video page.
Note When creating an MPEG-4 thumbnail on a Macintosh, you can only create a
snapshot of the first frame in the video. The thumbnail will always be the first frame
even if you take a snapshot in the middle of the video.
