Abstract
A Video On Demand (VOD) method consistent with certain embodiments involves processing content by selecting first portions of the content for encryption under a selective encryption system and selecting second portions of the content to remain unencrypted. The first and second portions are stored on the VOD server. If a request is received from the a device having decryption capabilities associated with a first decryption method only the first portions are routed to the encryption device and the second portions are routed around it. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
