Digital Rights Management is one of the main concepts in the field of digital media. Digital Rights Management arose as a set of steps that prevent the piracy of copyrighted content. DRM arose as a preventive measure, when the online piracy is at its peak. Online piracy increased with widespread usage of peer to peer networks. A group of technological companies joined hands together to stop this issue. As per the proposal made from the joined companies, DRM consists of embedding some instructions along with the copyrighted material in order to prevent its illegal use.
Digital Rights Management
What is it?
Digital content owners serving copyrighted material faced a serious problem because of online piracy. They had no control over how their copyrighted content gets distributed. DRM enables the authors to manage control over their copyrighted content over any network. As stated above, DRM involves adding some instructions along with the copyrighted material. These instructions imposes various restrictions on the digital content in the internet.
What are the DRM rules?
The embedded instructions along with the copyrighted material in DRM imposes the following restrictions
- The list of software in which the content can be executed or opened
- The hardware devices in which the media can be played
- The number of times the content can be copied
- The reading time or the amount of content that can be modified
The above said scenarios are the common ways. Many providers implement much more stricter rules based on the corresponding application domains.
What are the advantages?
The main and the most important advantage that the publisher gets through DRM is better control over the copyrighted content. Before DRM got introduced, the copyrighted content author had no idea of how the content is distributed. DRM provides a better level of control.
How is this useful for Samsung Smart TV?
Samsung Smart TV has a multitude of media related applications ranging from On-Demand, Streaming apps etc. These contents may be free to use for everyone or may require a license for viewing it. DRM helps the media owner in the second case, that is if the content is a restricted or a copyrighted one. Samsung Smart TV provides various provisions in its SDK to integrate DRM into its applications. The various APIs that provide DRM integration into the SDK. We will discuss the technical details of the DRM integration in Samsung Smart TV applications in the next article
What are the limitations of DRM?
Even Though DRM provides control to the copyrighted content developer, there are a number of limitations in implementing it successfully. There are certain cases where the DRM fails to provide complete protection from illegal usage of copyrighted content. The following are some of the common limitations
- Finding out who is replicating the content. The legitimate owner may take a copy of the content for backup purposes
- Reproducing the content by taking snapshots.
- Crack of the allowed list of software, in which a little modification may enable certain application options that enable the copy of the restricted content.
- Legitimate user intentionally providing the required tools or the access credentials for others to access.
Even Though DRM provides various advantages, there are lot of limitations in implementing it. DRM in the future is incorporating various technologies and methods to provide better control over copyrighted contents. It also aims at minimising the existing list of loopholes in the current DRM implementation. We will discuss on how to implement the DRM inside a Samsung Smart TV application in our next article.
