MPEG Features
Billboard
The Billboard feature allows you to display text and/or graphics on a TV monitor. The
displayed billboard can span multiple pages with each page displayed for a specified period of
time. Some uses of the billboard feature are to announce a daily calendar of events, directions
to a particular conference room or even a slide presentation in conjunction with displayed
video. VBrick models 62xx, 52xx and 53xx have a built in mini-browsers that support viewing
limited HTML pages. The pages can either be kept inside the VBrick as part of the file
system, or can be located on a remote HTTP server. Each page of the billboard is laid out as
an HTML page with text and graphics created using the HTML tags supported. If billboard is
to be supported on a remote server, the appliance requires read access to the HTTP server
and may need to be configured. See the MPEG-2 or MPEG-4 Admin Guide for
configuration details.
Picture-in-Picture
(PIP) VBrick Decoder Picture-in-picture (PIP) is a video display mode in which a small video
image is superimposed on a quadrant or smaller area of a video screen. This small image or
window can be opened in order to display a second video input source on a monitor. The
MPEG-2 decoder provides picture-in-picture capability, which allows the input from the
local encoder to be displayed on the local decoder's output. This is a useful capability when
using the appliances in video-conferencing mode by allowing the near-end user to view him/
herself in a small window while simultaneously viewing the far end. Note that PIP can only be
used to display local encoder input and is available for encoder/decoder models only. PIP does not
operate when closed captioning is enabled.
Embedded Web Browser
VBrick appliances have an embedded Web Browser that allows users to display HTML pages
on the decoder's output (i.e: a monitor). This is a powerful tool that can be used for data
collaboration across a network during video conferences. The web browser is a great tool for
allowing data collaboration between remote sites. Benefits and features include:
• It allows for exchange of .jpg, and .gif images and .html pages.
• Images or pages can reside inside the box (in flash memory) or on an external web
server.
• It can be turned On or Off through
Billboard key in both the IWS and on the remote
control.
• It operates with VBrick's SCAT program, allowing instant capture of Windows desktops
and transferring that image to a VBrick (or to any Web server).
Example 1
An HTML page and graphic image resides in flash. This is by default and when shipped from
the factory an HTML page example is loaded into flash memory. It will display several .JPG
images automatically when the billboard is turned On. There are 4 HTML pages with each
having a JPG image inside of it. HTML page 1 points to page 2, page 2 points to page 3, etc.
Note If closed captioning is enabled while PIP is enabled, closed captioning will not be
displayed on the monitor until PIP is disabled.
