For example, you can input RTP and TS (transport streams) into the DME and output those same streams as RTMP (Flash) or HLS (for Apple iOS devices). The DME also provides video content caching, storage, and serving to ensure that stored content is delivered from a DME as close to the end user as possible.

    Vbrick currently supports a variety of shelf and rack-mount models. See the latest DME Release Notes for a detailed description of DME models and specifications. There are no absolute rules for sizing a multipurpose device like the DME but there are some basic guidelines that can help you select the right model.

  • Page 55: Configure A Dme Stream

    The diagram below shows the most common input and output streams supported by the DME. The DME Input Streams shown on the left in the diagram are live inputs from a Vbrick encoder or streams from another live source—these streams can be inputs to either the RTP server or to the Multi Protocol server in the DME.
  • Page 56 9000 encoder. Please refer to this document when configuring the DME. This document is found on the Vbrick documentation website. The DME supports Adobe Flash Multicast as of v3.6. It is provided as an output from the multi-protocol server. For this diagram, this would be considered Out-13, Flash Multicast.

    RTP Server or the Multi-protocol server. This is determined by DME port that the stream is sent to. In general, In-2 is preferred to In-3. The only situation where In-3 should be used is if the UDP protocol is required. since IN-2 does not support UDP.
  • Page 60 The second name source is the incoming program name. In some cases, multiple streams with different bit rates are to be sent to the DME. In these cases, the unique program names are preserved using the Announce Session Name Override parameter to override the common program name.

  • Page 62: In-5 < Pull (Rtmp)

    2. This stream can now be redistributed in several ways by the DME. It can also act as a source for uses case Out-4 > Serve (RTP) and Out-11 > Push RTP via RTSP.

  • Page 63: In-6 < Pull (Rtsp)

    The stream packets are received as RTP and used as a source for any of the output protocols. Another use of this protocol is to pull the live stream from the DME's RTP server and deliver it as a source for one of the Multi Protocol server’s output protocols or as a source for transrating.
  • Page 64 To configure a pull (RTSP) input:  Objective: Pull an RTSP unicast RTP stream(s) from a source as input to the DME. If the stream is coming from an external server, like a Vbrick H264 encoder, follow steps 1 and 2, and 3.

  • Page 65: In-7 < Pull Transport Stream Using Rtsp

    For both of these options you will need to manually fetch the SDP file from the encoder and FTP it to the root folder (or a subfolder) on the DME. The SDP file has information describing the stream such as profile, bit rate, addressing, and transmission method.

  • Page 66: Dme Output Streams

    3. Select a transmitter to use for selected stream and setup the Destination Port parameter to send the stream out of a port that is not already used on the DME. This is a manual process to determine which other streams are on the DME. Usually, choosing a high number in the 20000 range is likely safe and will not conflict.

  • Page 67: Out-1 > Serve (Rtmp)

    H.264 video are supported, but for transport streams which are brought into the DME using a transport stream protocol and are transmitted using transport stream protocol, any codec will be supported. This allows support of MPEG-2 video in transport stream for this use case.

  • Page 68: Out-3 > Serve (Rtp)

    RTSP/RTP server to utilize. Live This output option requires no explicit configuration on the DME but is available for all live content present on the Multi-Protocol server, whether brought directly into the server or Pulled from the RTP server using an internal In-6. An example of a live publishing point is: rtsp://<dme_ip_address:port>/<streamname>...

  • Page 69: Out-4 > Serve (Rtp)

    Configure a DME Stream The RTP server on the DME serves RTP files. Play the stream in StreamPlayer, QuickTime, or VLC using a URL similar to this: rtsp://server:port/publishing_point.sdp Since the Multi Protocol RTP server uses an non-standard RTSP port – default 5544 – normally the port must be explicitly included in the URL.

    Unicast/Multicast RTP or In-3 < RTP Auto Unicast, or most commonly via an internal Push form the Multi Protocol server (Out-10), to be served via an RTSP server from the DME to clients that support RTSP streams. Additionally this server is commonly used for delivering VOD content.

You can play the stream in an appropriate player (see the table below) for example in a QuickTime, Flash, or HLS (iPhone) respectively using a URL similar to these: http://<ip_address>/filename.wmv...
  • Page 78 Objective: This use case allows files to be delivered via HTTP to a destination client. Files of type .wmv (Windows Media) cannot currently be served via the DME. Files can however be delivered via HTTP progressive download. This u is not restricted to WMV files, and almost any file type can be served via HTTP.

    Network IPV4 Network Interface 1 The DME supports up to four network interface (NIC) cards you can use to increase the bandwidth and throughput available to the DME. A DME with one NIC card has an overall bandwidth limitation of 1GB for all output streams. A DME with the load shared over four NIC cards provides 4GB of bandwidth.

    To avoid ambiguity in the handling of packets, a one-to-many NAT alters higher level information such as TCP/UDP ports in outgoing communications and maintains a translation table so that return packets can be handled correctly. The DME allows stream access through a direct IP address, a Natted IP address, or both.

    The DME identifies the stream as an Akamai stream. The DME will pull the requested content from Akamai, cache it, and deliver the content to the player. Other subsequent requests are pulled from the local DME cache, Mesh, directly from Akamai (in this order) and delivered to those players.

    M e s h w i t h R e v C a c h i n g C o n f i g u ra t i o n DME Mesh Architecture If you are using Rev with your DME(s), you will automatically utilize a shared cache that takes advantage of the DME mesh architecture. The goal of this architecture is for all your DMEs to communicate and reduce out-of-network bandwidth costs as a result.
  • Page 104 This is the general solution when dealing with HTTP based content. If it is not local, then the Mesh is inspected. If it is found in the mesh, it is cached on the second DME. If it is not in the Mesh, then the player will fall back to Rev delivery.
  • Page 105 When moving into the DME mesh, the following guidelines should be considered: • Do not add DMEs to Rev during peak use times. Adding a DME will cause a mesh update across all DMEs. This will cause playback disruptions as the mesh resets.

    The number of streams supported depends on the model of the DME. MPG2TS Streams The DME can accept a live unicast or multicast MPEG2TS (with an MP2 or MP4 H264 payload) and deliver it from the DME as unicast or multicast. (A live MPEG2TS is typically pushed from a a VB6000/7000/9000 Vbrick MPEG-2/H.264 encoder or another DME.)

    It is important to note that this feature only supports HLS streams originating from either (1) a DME HLS originated stream, or (2) via a Vbrick 9000 Encoder by way of RTMP push to Akamai (Stream Packaging) with HLS. No other HLS streams are supported at this time.
  • Page 131 Read only: Disabled | Connected | Receiving. Stream Preparation for HLS Pull In order to optimize the DME HLS Pull feature, the HLS stream should meet certain specifications. Specifically, within the DME all the HLS segments are combined into the native stream.

For example, when using the Vbrick 9000 Encoder, the setting is on the Encoder Configuration > Video Encode page, seen here.

    Possible destinations for Flash push include a Flash server or a CDN (content delivery network) like Akamai or EdgeCast. This is the preferred protocol for sending streams to another DME.
