An apparatus for providing an improved content protecting and packaging system for protecting content may include an extractor for extracting a content package into a plurality of content segments including a first portion and a second portion. An enveloper may envelop each of the content segments in the first portion separately to thereby create one or more protected content segments. Further, a packager may package the protected content segments with the second portion of the content segments into a protected content package, which may then be uploaded to a distributor for distribution to user terminals. A corresponding method and computer program product are also provided.
