View Live MPEG-2

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.Transcoder 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 Serverwowza
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, Internet streaming service providers, educational institutions, and major corporations.
