wherein said LCS determines that the digital content being delivered to the LCS is authorized for use by the LCS by comparing a watermark present in said digital content with an LCS watermark associated with said LCS, thereby making a watermark match determination, and only if said watermark match determination indicates a match then said LCS storing said digital content in said first LCS domain in said non-transient LCS rewritable storage medium in encrypted form, and only if said watermark match determination indicates a mismatch then said LCS rejecting said digital content from said first LCS domain so that said digital content is not stored in said first LCS domain;
said LCS determining if a watermark is present in said digital content, thereby making a watermark determination;
only if said watermark determination indicates no watermark is present in said digital content, said LCS degrading said digital content resulting in degraded digital content and then storing said degraded digital content in encrypted form in said first LCS domain in said non-transient LCS rewritable storage media; and
only if said watermark determination indicates a watermark is present in said digital content, said LCS making said watermark match determination;
wherein said LCS is designed to transmit either said digital content stored in said first LCS domain or said degraded digital content stored in said first LCS domain via said interface to said SU;
wherein said SU is designed to watermark the digital content that the SU receives from said LCS with an SU watermark, wherein said SU watermark is unique to said SU;
wherein the SU is designed to play the digital content;
transmit the digital content to a player other than the SU;
or both.

Abstract
A local content server system (LCS) for creating a secure environment for digital content is disclosed, which system comprises: a communications port in communication for connecting the LCS via a network to at least one Secure Electronic Content Distributor (SECD), which SECD is capable of storing a plurality of data sets, is capable of receiving a request to transfer at least one content data set, and is capable of transmitting the at least one content data set in a secured transmission; a rewritable storage medium whereby content received from outside the LCS may be stored and retrieved; a domain processor that imposes rules and procedures for content being transferred between the LCS and devices outside the LCS; and a programmable address module which can be programmed with an identification code uniquely associated with the LCS. The LCS is provided with rules and procedures for accepting and transmitting content data.
