Abstract

A system for secure and non-secure distribution of digital content of digital content, such as digital audio or video data (103), over the Internet or other computer network (101) starting from a server (102) to a personal computer or other computing platform (100) and then through conversion to analog audio or video for listening or viewing on an audio or video player (106, 107). An important aspect of the invention includes wireless transmission of either digital audio or video data (103) or analog audio or video from the computing platform (100), through an audio or video transmission peripheral (104), to an audio or video receiver device (105) and finally to an audio or video player (106, 107).
