Up until now, there is no clear way of telling if device that creates media (such as a PVR) infects the media with DRM restrictions.  For example, many manufacturers happy promote the number of hours, the quality, etc. their device can record, but make no mention of whether the content made can be played else or even what devices it may be played back on.  For example, many PVRs offer no user friendly to directly copy their content to another device and some that do will only allow copying to devices that are compatible with its DRM to prevent any further copying or transferring.  To help promote devices that create DRM-free content, the Consumer Electronics Manufacturer Neuros Technology has created the Unlocked Media Trademark, which is intended to be used as a consumer friendly way of saying "DRM Free".

The trademark will be made available free to anyone that uses open standard technology and makes it available on a non-discriminatory basis.  Neuros is currently in the process of looking for an independent third party to administer and manage this trademark.  It also hopes to promote the Unlocked Media brand and to get organisations involved in creating devices that record content free of DRM to unite and use the trademark.  The purpose of the trademark is to benefit the consumer and to promote the device as capable of creating media that can be played and stored virtually anywhere. 

It will be interesting to see how many manufacturers would be willing to take this on, as it would let consumers who see the logo know that this device does not restrict content created by it.
