Digital Signage Standard by POPAI

Currently digital signage implementations are mainly proprietary, and that means once you choose a vendor you are stuck with it, unless you completely change your network and the way you manage your content or handles separate systems. If the digital signage industry really wants to take off some standards are needed. One of the first standard for digital signage has been released by POPAI (Point of Purchase Advertising International).

POPAI also used to provide some media samples to test your system previously available at www.popai.com/DS/ContentSamples but the link is […]

Digital Signage Features – A Quick Guide to Select Your Digital Signage Solution

There are a lot of different digital signage solutions around and it may be difficult to find which one is right for you since there can be quite a few different features and options. So I’ll do my best to explain the main features to guide your choice if you are planning to purchase a digital signage solution (embedded signage player, content management software and server).

Where to get video, audio and image samples

If your system is dealing with media files such as video, audio and image you’d better get some samples to make sure your system can play most of them or at least can match (or beat) the competition using the same platform. So I’ve collected some links for just doing that. mplayer test samples: http://samples.mplayerhq.hu/ – Over 42 GB / a few thousand files of diverse audio and video files. Microsoft HD Showcase – http://www.microsoft.com/windows/windowsmedia/musicandvideo/hdvideo/contentshowcase.aspx – A must to test wmv, wma and wma pro decoding capabilities. For testing MKV videos, you’ll most likely need to download some videos using bittorrent or emule. To search for video you can use sites such as http://www.isohunt.to or http://www.verycd.com/. Very CD is actually one of the top website in China in terms of traffic. You can also convert some other videos to MKV using some MKV editors my favorite being mkvtoolnix. For graphics […]
