SYSTEM AND METHOD TO PROCESS MEDIA WITH PRESET CREDIT

摘要

A preset credit media includes: a document part, and availability information and credit for the document part. The document part is all or less than all of an audio file, a visual file, a text file, or a data file. The availability information includes a monetary cost or time availability for the document part. The credit includes a monetary credit, a time credit, or a transaction credit for the document part. To play the document part, it is determined if enough credit exists for the document part to be played, based on the availability information and the credit. If so, the document part is retrieved from the preset credit media and played. The credit is modified accordingly. To change a preset credit media, a change request is received and verified. Any combination of the document part, the availability information, and the credit may be modified according to the change request.
