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 streams.
Up to 30 simultaneous transcode streams are supported.
For organizations that have deployed live MPEG-2 multicast from
VBrick and others, or have live MPEG-2 from satellite links such as
Exterity, 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.
- 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.
- 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
A Lot Of Money
If you have existing
MPEG-2 encoders
(e.g. VBrick 6000
series), 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
$1000 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 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.
Flash or QuickTime
The output of the Live Transcoder is H.264 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.
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.

FAQ |
- Does the Live Transcoder support file recording?
- Not currently. The Live Transcoder delivers live H.264 as a RTP or
RTMP stream. Recording can be done by receiving and
recording the live stream.
- Does the Live Transcoder support Adobe Flash?
- Yes. If RTMP is selected, you can send your live
transcoded video to a Flash Media Server, Wowza server,
compatible CDN, etc. You can receive the live video using
Adobe Flash Player 10 or above.
- We do not currently support live RTMP input.
- Does the Live Transcoder support multicast output?
- Yes. For multicast output, you would use RTP and set the
output multicast address and ports. The Live Transcoder then
creates the necessary SDP file which you use to view the
live video (i.e. via QuickTime player).
- Can I use the Live Transcoder with other live MPEG-2
video sources?
- Yes, the Live Transcoder supports standard MPEG-2
Transport Stream ("raw" format), as delivered by many
encoders and systems. You can check compatibility by
using the
free VBrick StreamPlayer, or the
free VLC
player.
- Can I input standard WM streams?
- Yes, most standard WM streams are supported.
- Server-side playlists are not currently supported,
although this is under development (as of 8/2010)
- Can I input any MPEG-2 stream?
- Not exactly. DVT supports MPEG-2
Transport Streams only. There are some streams that are sent
in Program Stream or other formats that will not work.
- The MPEG-2 audio must be conventional
MPEG1/Layer2. AC3 audio is not currently supported (as
of 8/2010)
- Can I stream to iPhones / iPad / iTouch?
- Yes, using the optional Wowza Media
server. The Media Server will stream directly to
players from the server. You may also be able to push or
pull the stream to a CDN for increased scale.
-
Does the system support satellite broadcasts?
- Yes. The system work with direct satellite receivers
such as Exterity and others.
