摘要： A method and system for controlling access to media content distributed within a premises is described. One embodiment of the system receives, at the premises, digital content and associated rating information; decodes the digital content to produce decoded content, the decoded content including a particular program from the digital content; embeds with the particular program in the decoded content a rating indicator corresponding to rating information associated with the particular program to produce rated-decoded content including the particular program; modulates the rated-decoded content to produce rated-modulated content including the particular program; and transmits the rated-modulated content to an analog television located on the premises that is capable of selectively blocking the particular program based on the embedded rating indicator. The system thus restores rating information that would otherwise be lost when digital content is converted to analog format for distribution to analog televisions within a premises.
