The VBrick Distributed Media Engine (DME) provides dynamic live stream creation, bandwidth optimization, and automated and intelligent video-on-demand (VoD) sharing and prepositioning. A typical deployment has one or more central DMEs connected to edge DMEs. A single stream of media from a central site can support tens of thousands of live views and then be stored locally for on-demand access by thousands more. Combined with VBrick Rev, an enterprise video management platform, the DME becomes a powerful, integrated component that intelligently and automatically delivers borderless live and stored content to users.
The DME also uses the DME Mesh, which is a set of technologies that provides a self-managing, self-optimizing ability to share, distribute, and cache VoD content Mesh capabilities also enable video content location across DMEs and first-request caching. This capability allows administrators to selectively preposition content, and enables DMEs to locate and pull that requested content from the closest DME on the network, using bandwidth and storage only when necessary. Focusing on these operational savings is a vital part of an eCDN that allows you to make high-quality video available to massive, geographically dispersed audiences, all without overloading your WAN. Plus, the DME supports video ingest and recording for a variety of endpoints, including popular smartphones and media tablets.

Origin streaming server
The DME has Real-Time Transfer Protocol (RTP), Real Time Message Protocol (RTMP), HTTP Live Streaming (HLS), and HTTP Progressive Download server capabilities for stored (VoD) files. When a software client requests a served stream, the DME server examines the file to determine transport type, video rate, audio rate, and other parameters and then plays the stream using optimal settings adjusted for bandwidth, frame rate, and other parameters.
-
Pushed streams
The DME also pushes live streams to configured endpoint destinations. In pushed stream mode, the DME is always transmitting and does not wait for a client request. The DME transmits if the client is reachable and listening (in the case of unicast). The streams are transmitted across the network with RTP, RTMP (unicast only), or transport stream.
-
Pulled streams
The DME can receive or pull from an encoder, a Flash server, a video conferencing device, or another DME. The DME can also serve streams or push streams to an RTMP server, RTP server, or another DME. The DME supports unicast (one to one) and multicast (one to many) for both input and output. Multicasting can save substantial network bandwidth when multiple clients are accessing the same stream.
-
Transrated streams
The DME can transrate live video streams by converting a stream from one bit rate and resolution to another. A common example is to ingest a single bit rate stream and transrate it into smaller bit rates. Those streams are then commonly combined into a single HLS adaptive bit rate delivery for platforms from mobile (lower bit rate) to PC or desktop (higher bit rate).
-
Transmuxed streams
The DME can transmux live video streams from one file format or streaming protocol to another without changing the compression method. An example of transmuxing is when a unicast stream is converted to multicast or when an RTP stream is converted to RTMP. The DME supports a wide range of input streams and live output streams.
-
Unicast to multicast
The DME can receive unicast streams, by the mechanisms list above, and create multicast streams. This capability is highly useful for bandwidth savings between origin servers and remote offices. Converting into multicast also conserves bandwidth on the LAN, and avoids the network load of many, multiple unicasts.
