The Discover Video Live Transcoder
(DVT) receives live MPEG-2 video
multicast video streams and standard Windows Media streams and converts them in real time to live H.264
and WM streams.
Up to 30 simultaneous transcode streams are supported. With the
optional Media Server, you can deliver live streams directly to
iPhone/iPad/iTouch as well as to Flash Players, Silverlight, and
more.
For organizations that have deployed live MPEG-2 multicast from
VBrick and others, or have live MPEG-2 from satellite links such as
Exterity, Breeze, and others, the Live Transcoder allows you to deliver your
existing live video to viewers over the public Internet The Live Transcoder can achieve better than 100:1
compression, allowing you to convert a high speed live MPEG-2 video to
any bit rate you desire, such as 300 Kbps.
For organizations that have deployed standard Windows Media
streaming (unicast or multicast), the DVT allows you to stream in
one format, yet deliver your stream in multiple formats without
using additional uplink bandwidth.
- Educational Institutions -- Deliver your existing live
MPEG-2 TV channels to other schools and buildings using the
public Internet
- Transportation Departments -- Send your live highway surveillance video feeds to
multiple districts, state officials, emergency workers, etc.
- Streaming Service Providers -- Convert your new or existing
Windows Media streams to live H.264 and deliver to Flash player
and mobile devices.
- Commercial Organizations -- Add public Internet or private network low speed delivery to your
existing MPEG-2 infrastructure
- Government / Defense -- Transmit one, some, or all existing live MPEG-2 video feeds to remote
locations over virtually any network, including cellular.
- Commercial Broadcasters -- Use your existing MEPG-2
Transport Stream infrastructure to deliver
simultaneous webcasting for commercial linear broadcasting over
the web, or for monitoring you feeds. Customers that use
VC-1/Windows Media (e.g. U-Verse) can instantly deliver the
video in Flash format.
- Satellite Receivers -- Receive direct broadcasts from
satellite and use IP receivers (e.g. Exterity) which will send
each channel as a MPEG-2 stream. Rather than multicasting high
bandwidth (e.g. 5 Mbps) streams, deliver using H.264 multicast
directly from the DVT, and/or deliver over the public Internet
via Flash player.
High Quality
Organizations typically selected MPEG-2 video to achieve broadcast
quality video distribution. MPEG-2 requires 3 to 8
Mbps to achieve this quality, which is not an issue in
multicast-enabled local area networks. H.264 provides an order of magnitude
improvement in compression efficiency and can deliver the same
quality at about half the bandwidth. Stunning live transcoded video
delivery can be achieved at 500 Kbps, very good quality at bit rates as low as 200 Kbps,
and applications such as video monitoring are supported at rates as low as
40 Kbps. Of course, you can also maintain existing broadcast quality
and even send H.264 via multicast at substantially reduced streaming
rates.
Save Money
If you have existing MPEG-2 encoders, the Live Transcoder can be much more cost effective than replacing the MPEG-2
encoder with a H.264 encoder. The Live Transcoder can cost under $400 per transcoded
stream vs. many thousands of dollars for a new encoder appliance.
Moreover, any organization that could not deliver their live
MPEG-2 video to a remote location because they did not have
sufficient bandwidth can now deliver it with ease.
Send your new or existing live
MPEG-2 or WM video via multicast within your LAN, and use the Live
Transcoder to deliver your live video
virtually anywhere via your private network or via the public Internet.
Windows Media users
can now stream in their native WM format, but also in Flash or
QuickTime format. The alternative is typically to run two encoders
which often requires more bandwidth than may be available and adds
complexity.
Flash, QuickTime or Windows Media
The output of the Live Transcoder is H.264 or WM at user-definable video
rate, frame rate, resolution, and audio rate. Per industry standards
and conventions, each output stream may be standard RTP or Adobe
RTMP. For RTP, the Live Transcoder automatically creates a SDP
file that you may use on a compatible streaming server such as
Darwin, Helix, Wowza, etc. and view via H.264 players such as
Apple QuickTime player. For Adobe RTMP, the Live Transcoder
does a live "push" to a compatible Flash server such as Adobe, Wowza,
etc. and you can view your live video using Flash player. If the output is set to
Windows Media, then either push or pull is available for each stream.
Mobile -- iPhone/iPad/iTouch, Blackberry, Android
DVT allows you to stream to virtually any mobile device when coupled
with the optional Media Server. DVT overcomes the common issue
of needing to provide high quality / high rate stream for desktops
yet lower rate streams for 3G mobile devices.
Integration
The Live Transcoder behavior can be configured with simple XML
files. This makes it very easy to integrate with 3rd party and
custom system. No "SDK" is required.
Reliability
Live Transcoder runs as a Windows Service that automatically starts
when Windows starts. The system automatically recovers if the source
MPEG-2 multicast stops and starts, allowing you to control your
stream by simply starting or stopping the source multicast.
The system has been designed to run 7 x 24.
Simultaneous Capacity
Depending on the host platform, up to 30 simultaneous live
transcodes are possible. Discover Video offers the transcoder
in several platforms, and as a software system for your own
computer. The actual capacity depends on the input and output
settings (fewer live transcodes are possible at higher resolutions
and rates).
Optional Wowza Media Server
The DVT can come with an optional custom Wowza Media Sever.
The server will automatically detect your live transcoded video and
deliver directly to iPhone / iPad / iTouch devices, to Flash
Players, and to Silverlight players.
With the optional Wowza server, you have one platform that allows
you to stream your MPEG-2 and Windows Media streams to virtually all
playback devices.
Windows Media / Reflecting
DVT supports the ubiquitous Windows Media forma for both inputs and
outputs. This allows you to deliver your existing MPEG-2
streams in WM format, eliminating the need to install a player on
most enterprise desktops. It also allows you to do enhanced
"reflecting" -- transmit your WM video at one high rate and deliver
it via either push or pull to viewers at multiple rates.

FAQ |
| How do I control DVT? |
DVT has a
service
manager that
you can open
to view and
manage DVT
channels.
Configuration
of each
channel is
via
conventional
XML files.
You can
easily edit
each XML
file to set
you channel
values, and
you can
easily
integrate
with
higher-level
management
systems that
can modify
these XML
files as
desired.
Any change
to an XML
file is
automatically
detected
on-the-fly.
Some
customers
like to edit
the XML
manually;
some elect
to upload
new XML
definitions
via FTP;
some use
server-side
script. |
| Does DVT support 16x9
and other video sizes and resolutions? |
Yes, you can
set your
output frame
rate, video
rate, audio
rate, and of
course width
and height
as desired.
16x9 HD
resolutions
are commonly
used for
commercial
free-to-air
satellite
broadcasts,
and
increasingly
for pure
Internet
streaming. |
| Does DVT support file
transcoding? |
Yes.
You can set
any channel
to be a file
transcoder.
A file
transcoder
will detect
a video file
(.mpg, .wmv,
.avi, .mp4)
in input
folder "A"
and
transcode it
to WM or
H.264 and
put it in
output
folder "B". |
| Can I add my watermark
to the output? |
Yes. You can
specify a
"watermark"
image,
overlay
location,
transparency,
etc.
This allows
you to
easily brand
your output
stream.
You can even
change this
on-the-fly,
making it
useful for
real-time
banners,
news, lower
third's
titles, etc. |
| Does DVT support
snapshots? |
Yes. You can
configure
DVT to
create a
jpeg image
every N
seconds for
each input
stream. You
can have do
snapshots-only
if desired. |
| Do I need the Media Server Option? |
Without the
Media
Server, you
can stream
directly to
CDN or other
Media Server
in Flash,
WM, or RTP
format. You
can deliver
live
multicast
via RTP.
With the
Media
Server, you
can deliver
unicast
streams
directly to
client. |
|
What can
I set
for the
output
video? |
For each
channel, you
can set
video and
audio rates,
resolutions,
frame rate,
snapshot
size and
frequency,
and type
(RTP, RTMP,
WM). |
|
Does DVT
support
iPhone and
Blackberry
mobile
devices? |
Yes. i-Devices support H.264 video. You must of course
deliver it
via a
compatible
Media Server
or CDN
(Discover
Video can
provide such
CDN service
if desired). |
|
Does DVT
support
Flash? |
Yes. DVT
streams
directly to
compatible
Media Server
or CDN using
RTMP. |
|
Does DVT
support
Windows
Media? |
Yes. DVT
streams
directly to
compatible
Media Server
or CDN using
Windows
Media push
or pull. |
|
Does DVT
support
satellite
broadcasts? |
Yes. Most
Free-To-Air
broadcasts
are MPEG-2
Transport
Streams. |
|
What are the
input types? |
Live WM or
live MPEG-2.
Other types
coming soon. |
|
Why not
stream in
multiple
formats to
begin with? |
You
certainly
could.
But many
locations
simply do
not have
enough
bandwidth to
support
multiple bit
rates and
multiple
formats for
the live
uplink,
especially
from
temporary
venues.
DVT allows
you to
stream at
the highest
rate
possible and
deliver your
live stream
in multiple
formats,
resolutions,
and rates. |
|
Who uses
DVT? |
DVT is in
use by the
U.S. state
transportation
departments,
