1. A system for receiving, processing, and playback of limited-use digital data, comprising:

  • circuitry for receiving limited-use digital data;

    memory circuitry for storing the limited-use digital data as stored limited-use digital data;

    playback circuitry that reads the stored limited-use digital data from said memory circuitry and converts the stored limited-use digital data to electronic signals for driving a playback device;

    processing circuitry comprising software to control operations of said memory circuitry and said playback circuitry and to control at least one operation performed upon the stored limited-use digital data as permitted by at least one restriction on the use of the limited-use digital data;

    a user interface operatively connected to said processing circuitry for programming one or more processing functions to be performed by said processing circuitry; and

    at least one digital output operatively connected to said processing circuitry that communicates with a data supplier to allow monitoring by the data supplier of the at least one operation performed upon the stored limited-use digital data as permitted by the at least one restriction on the use of the limited-use digital data,wherein said processing circuitry further comprises a program for transferring to a portable playback device the stored limited-use digital data and control data for use by the portable playback device for performing a virtual return of the limited-use digital data that has been transferred to the portable playback device.
