摘要：
The present invention allows for efficient use of conditional access resources by providing a network comprising a plurality of host devices for rendering decrypted content and one or more conditional access modules to enable said decryption. The network is configured so that any of the host devices may send received content to whichever of the conditional access modules is configured to perform the decryption, depending on the scheme which was used to encrypt the received content.
