DLNA and UPnP AV in the business

Originally posted: 5 January 2009, Updated 6 July 2009

Very often, DLNA and UPnP AV are typically marketed as being for use in the home due to the reduced amount of configuration needed for devices that comply to these standards. But devices based on these standards can appeal to business use, especially to small “mum and dad” shops, community / religious organisations and other similar businesses who don’t have regular access to “big business” IT resources.

The functionality is typically available as low-cost or free software or, in some cases like Windows XP and Vista, available as part of the operating system. There are some “business-grade” network-attached storage boxes that have the functionality for business continuity as well as the ability to work as DLNA-compliant media servers.

The main issue that one will have with this kind of setup will be that the network that you intend to connect the equipment on must be on the same subnet or logical network, served by the same DHCP server. This will be fine for most small-business, and SOHO networks, including the “private” segment of networks that provide Internet access to the public such as wireless hotspots and Internet cafes.

If you are concerned about security of business data or the integrity of business systems, you could run a separate server for the DLNA-presented media data rather than use the main server for this purpose. Then you can lock down the main server as tightly as it should be for the data.

Visual Merchandising

DLNA-based setups can come in to their own when it comes to all sorts of visual merchandising applications. This is more so for small businesses who cannot afford to buy business-grade "digital signage" or find the "digital signage" difficult to manage due to complex setup requirements.

You can have images or videos of products that are always kept fresh and up-to-date and can intermingle these images and videos with up-to-date “electronic signage” that you create with programs like Microsoft PowerPoint. The best example of this being used would be the real-estate agent who uses the setup to show pictures of the houses he has currently for sale or a beauty salon showing examples of the most fashionable hairstyles they have done lately.

A DLNA-compliant network electronic picture frame like the Kodak EX1011 or the D-Link DSM-210 can work wonders here as can any DLNA-compliant network media receiver (or games console) hooked up to a large flat-screen TV or monitor. Similarly, a DLNA-compliant flat-screen TV like one of Sony’s recent LCD TVs can fulfil the same needs here, especially now that the cost of these sets in in affordable territory and the sets are available from most electrical retailers.

The media server can be part of the file server’s functions or can be hosted on a separate box such as a network-attached storage unit. You just need to add the media to this server by using a standard network file-transfer protocol like SMB or FTP.

You will need to make sure that the media server presents the files either by keywords (tags) and / or folders of the file system so that you can file the pictures how you want to file them. Windows Media Player and TwonkyMedia do support working by keywords and folders.

If you use a presentation program like Microsoft PowerPoint to create “electronic signage”, you just need to export all of the slides in your presentation as JPEG files in to a folder available to the media server. This is done in PowerPoint by opening the presentation and selecting “File” – “Save As” and selecting “JPEG” as the file type. You then have the option of exporting the current slide as a JPEG or exporting all the slides in the presentation as JPEG files in a folder named after the title of the presentation.

Background Music

If you are sick and tired of the radio or those business-to-business music services, you can use a computer as a music server, with the music playing out through a DLNA-compliant network media player such as one of those Internet radios.

As I have mentioned in my previous DLNA feature articles, it is very easy to do whether you decide to use a computer or a network-attached storage box as a media server. Most of the network-enabled music players support shuffle-play which can be very useful for this application and a lot of them have a line-out connection so you can connect them to a public-address amplifier or music-on-hold interface.

Education – The media library

A DLNA-based media system can work well when it comes to education. It doesn’t matter whether the idea is to show a video to a class or whether a student is viewing a video they saw in class “once more” in the library.

A capable DLNA media server with a properly-indexed media collection can work wonders here, with the users selecting the AV material through the DLNA media player’s user interface. Most such players can connect to existing AV equipment or the DLNA functionality can be part of the equipment’s functionality.

Similarly, if the media server provides it, you could allow Web-based access via any computer connected to the facility’s network. This can allow wireless-linked computers to be used to “pull up” the learning resources.

Other business-based DLNA applications

DLNA is eventually heading in the direction of a common IP-hosted data system for transferring media between portable and fixed devices. A typical application may include uploading images and movies from a digital camera or camcorder to a “base” computer for editing and viewing. Similarly, there may be the application of downloading AV material from a computer to a smartphone so it can be viewed on that phone’s display.

Conclusion

What needs to happen is that DLNA needs to be viewed as not just being for the home but being for business and educational life as well.

My Comments:

Previously, I had made some comments about the NETGEAR Digital Entertainer Elite network media receiver / server that was previewed last year. I had mentioned about Netgear considering the possibility of extending its functionality as a DLNA media server, especially since it has a user-replaceable 500G SATA hard disk built in.  The original model that was talked up happened to be the EVA-9000 but this model that is now released is the EVA-9150, but this unit is part of the same series.

Now it is released worldwide rather than being “dribbled out” in to different countries over the year. It is selling for a manufacturer’s retail price of USD$399 which may mean a likely street price of USD$300-350. This may make the unit more suitable for people who have invested in good-quality flat-screen installations.

It would also come off as being useful in the “small-business” context for “digital signage” and similar applications, whether you upload the pictures to the hard drive or hook the unit up to a computer or NAS running a suitable DLNA server. Here, a “showcase” of regularly-used material can be kept on the hard disk, but other material can be held on computers that are on the business network.

I am certain expecting that this could bring Netgear further in to the network media receiver market and will make this market competitive.

My comments

Now Netgear is raising the bar as far as these network media receivers is concerned. It is an attempt to provide a UPnP-complint high-end network media receiver for those of us who want to bring the video files held on the NAS unit to the home theatre that has the big plasma screen and surround-sound.

The built-in hard disk option could be improved upon in the form of being able to be a UPnP AV / DLNA media server. This can then lead to the unit being an entry-point media server or supporting the provision of “load ‘n’ show” media being available on other DLNA media devices in the home network. This is if the purpose of the optional hard disk isn’t just for downloading content as part of an rental-based or subscription video-on-demand service. Another ideal function would be to be under the control of another UPnP AV control point, whih can allow it to play audio content without the user needing to have the TV on to choose the content.

It will be interesting to see what the reviews in the computer press and the blogosphere think of this unit and its usability.
