A move from tape-based systems provides flexible programming.

360 Systems Maxx 6T

As with almost all components of today's audio/video production universe, corporate communications are moving away from tape-based systems to adopt file-based protocols. At the heart of this migration is the increasing use of digital media servers to get the corporate message out to boardrooms, training facilities, meeting centers, lobbies, and the Internet.

Media servers, which can be either single- or multichannel designs, bring with them the benefit of flexible programming, increased storage capabilities and, best of all, significant cost savings. Many corporate IT departments are therefore making the same discovery that broadcast newsrooms have known for a while — the savings gained by eliminating the maintenance cost of tape systems and communicating from servers can pay for the whole installation in a relatively short period of time.

By definition, a media server is a computing device that stores, manages, and shares media of all types. That can range from network-attached storage (NAS) to a media center's desktop PC or a commercial web server. Actually, any networkable computer with a large hard drive or sufficient solid-state storage can be considered a server, which means any desktop PC with the proper software and a network connection could qualify. (Although systems with multicore CPUs and even RAID storage will get the message out with greater efficiency.)

According to Douglas I. Sheer, CEO of DIS Consulting in New York, a leading supplier of syndicated market research reports, the role of servers in corporate and institutional installations is continuing to expand as file-based video predominates, and users continue to retire videotape recorders in exchange for disk and hard drive solutions.

“In the latest global survey, Broadcast Servers World 2007, we see that of the overall server channels reported, 29,013 installed channels were attributed to institutional users, of which corporate comprised about 20 percent (or 5,802 channels),” Sheer says. “Of those channels purchased in 2006, 7,007 were institutional channels, with 20 percent of them, or 1,401, derived from corporate purchasers. Planned institutional purchases in 2007 were expected to be 7,836 channels, with 20 percent or 1,567 expected to be corporate channels. Although the corporate market was a bit late in adopting servers, it appears to be making up for lost time in the VTR replacement trend, and their channel purchases are expected to ramp up rapidly in the next few years as they build out server capacity.”

Unlike their broadcasting cousins, corporate servers are not locked into using over-the-air TV's ubiquitous MPEG-2 compression, and they are free to more easily incorporate newer technologies such as H.264 (MPEG-4, level 10) compression for greater efficiency. Able to squeeze more than twice as much information into the space needed by MPEG-2, H.264 is often called “AVC” (for Advanced Video Coding) in the multimedia world.

Flash video from Adobe, containing video bitstreams that are a variant of the H.263 video standard under the name of Sorenson Spark, is also a common file format for delivering information over the Internet because it can be read on almost any desktop PC running free Adobe Acrobat Reader software.

Now, Microsoft is coming out with Silverlight, a competitive format that the company describes as “a cross-browser, cross-platform plug-in for delivering the next generation of .NET-based media experiences and rich interactive applications for the Web.” Silverlight has been code-named “Windows Presentation Foundation/Everywhere” or “WPF/E.” A beta version of Silverlight is currently available from, while the final edition is scheduled to be out by the end of summer.

With the proliferation of servers, many manufacturers are designing systems with unique capabilities. Therefore, this article will specifically focus on purpose-built media servers intended for corporate installations — as opposed to PCs loaded with third-party software. It should be noted that several companies that make mainframe servers for broadcast and data applications, such as IBM and Harris, politely suggested their systems not be included in this article because they are not specifically designed for corporate communications. Still, keep in mind that elements of technology from those companies are being used in various ways by the corporate market.

A recent trend in corporate servers is the need to interface with popular broadcasting nonlinear editing systems (NLEs), such as Apple Final Cut Pro, Avid Media Composer, and Adobe Premiere Pro. With the cost of video production equipment becoming affordable, including gear for shooting and editing high-definition video, inhouse media departments are increasingly being asked to create their own programming. Naturally, the servers intended to distribute these productions need to be HD capable as well, and a growing number of servers can now ingest files directly from those sophisticated NLEs.

Therefore, the technology inherited from broadcast-quality servers is raising the bar for all the players in this game. With all that in mind, here is a look at many of the most interesting media servers designed for corporate use.

Doremi Labs V1-HD/LE


The latest media server from 360 Systems is its Maxx 6T, which can deliver more than 700 hours of programming from its 6TB of RAID-6 storage. Maxx 6T functions as a video recorder, 3-channel playout server, and a graphics store with key-and-fill.

Its standard features include composite and SDI video ports, a frame synchronizer for recording satellite feeds or other sources, and a complete set of audio formats including AES/EBU digital, +4 balanced analog, and SDI-embedded audio. 360 Systems' Maxx 6T can simply drag and drop MPEG-2 files (including IMX) and DV-25 files over Gigabit Ethernet directly from NLEs, letting it interface seamlessly with a corporation's graphics, training, or public affairs departments.

Having already delivered 60,000 embedded media devices globally, Adtec Digital now offers the edje4000, a realtime streaming AVC/H.264 (AVC) encoder with broadcast-quality video. It features composite and SDI inputs through a time-base correcting video pre-processing block that removes spatial noise and temporal artifacts, and generally improves encoding efficiency with pre-processing balanced analog and embedded audio via SDI. Industry-standard RS-422 (9-pin) device control is optional, as is the ability to capture live video and audio.

For HD plasma and LCD displays, Adtec Digital also offers the displayMate featuring AVC/H.264 and MPEG-2 high-definition and standard-definition file playback from 4GB or 8GB solid-state storage and IP stream decoding. A corporate IT department can stream content to the displayMate over IP for point-to-point or multicast playout, and the media server automatically scales the content with advanced scalar algorithms to match a monitor's needs up to 1080i for improved HD playback. Adtec Digital servers support closed captioning, which is required for most government contracts.

Unlike many other dedicated high-definition video players, the Digital Video Machine HD from Alcorn McBride plays MPEG-2 at extremely high bit rates — up to 50Mbps — delivering very high picture quality. The Digital Video Machine HD can also synchronize perfectly to external sources, so multiple units can be frame-locked together for multiscreen or 3D stereoscopic applications.

All ATSC video formats are supported, including 1080i/30 and 720p/60. Video output is either component RGBHV or YPbPr. The Digital Video Machine HD Pro model also includes HD-SDI (SMPTE-292M) digital video output, and it provides either bi-level or tri-level sync on its analog YPbPr output. Control of the Digital Video Machine HD uses serial RS-232 or Ethernet, through which the operator can create complex sequences with playlists, or use the realtime scheduler for completely automated operation.
