Introduction to Digital Rights Management - DRM

DRM Digital Assets

A digital asset is a digital file or data that represents a valuable form of media. Digital assets may be in the form of media files, software (e.g. applications) or information content (e.g. media programs).

Digital content is raw media (essence) that is combined with descriptive elements (metadata). Metadata is information (data) that describes the attributes of other data. Metadata or Meta tags are commonly used to provide technical and descriptive information about other data. (Metadata is data that describes other data). A television program may contain technical metadata that describes the media encoding formats and duration of the media along with descriptive metadata that provides information about the title and actors.

In addition to digital assets that may be acquired or originally recorded (such as video from a sports game), digital assets may be combined to create new digital assets through the production and editing process. This process produces secondary content. An example of secondary content is the creation of “sports highlights” from a series of games that were previously broadcasted.

Digital assets are typically stored in a high-resolution version so they that can be converted (transcoded) into lower resolution formats as required. High-resolution digital assets require an extensive amount of storage area so older or less used digital assets are commonly moved to offline repositories. The original digital assets (master files) are commonly stored in a secure area (called a “vault”) which usually has restrictions on use or have usage costs associated with the content. This vault may be an electronic storage facility (e.g. videodisks) that is protected by a password system and data network firewalls.

Some of the key types of digital assets include digital audio, images, video, animation and application programs. There can be many other types of digital assets including web pages, scripted programs (e.g. Javascript files), fonts and other types of media that can be represented in digital form.
