Abstract
The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory or storage device) for a session-based encryption (e.g., a common-tier encryption) for delivering a content (e.g., video, data, multi-media content and the like) on demand using multiple encryptors. According to an embodiment, the STB's request for a VOD session may be routed by a session resource manager (SRM) to receive content from an appropriate encryptor chosen from multiple encryptors based on a predefined criteria. This approach can minimize a number of encryptions/encryption devices (such as ECM generators) needed in a cable network. However, the simulcrypt encryptor can be also used, if necessary, e.g., when CAS-only encryptors are fully loaded with a traffic.
