Digital rights management to protect copyrighted materials is a common element of consumers accessing content for a variety of uses including business and recreational. Such techniques have been generally deployed on small items of multimedia content such as individual tracks of music. However, at present despite the penetration of portable electronic devices for texting, telephony, email, and music their use by consumers for video, film, and large multimedia content has been limited in part due to the issues of downloading and handling individual files of hundreds or thousands of MB. It would therefore be beneficial to provide a means to download large multimedia content files and render these upon a variety of portable electronic devices whilst allowing the downloaded multimedia content to be securely stored within a portable memory device allowing the user to render the content upon their own electronic devices or other electronic devices without re-distributing the content.
