Digital transactions for the delivery of media files
First Claim
1. A method of delivering a digital media file to a receiving device, comprising the following steps:
- a) dividing a master version of a digital media file into a first series of time frames and a second series of different time frames;
b) delivering the first series of time frames to one or mote users without any form of access control, the first series capable of being used to form a version of the media file which is incomplete and/or corrupted;
c) delivering the second series of time frames to one or more said users the second series capable of being re-combined with the first series to form a re-assembled version of the media file which is complete and uncorrupted, in which access to the second series is only granted to users satisfying defined access control criteria;
wherein the receiving device automatically records a defined time period of the first series of time frames irrespective of any user selection of a record function of the receiving device; and
wherein the defined period is adequate to enable a user to record an entire media work even though the user only selects the record function of the device substantially after commencement of receiving the media work.

Abstract
An incomplete/partly corrupted media file is delivered ‘in the clear’; in addition, a delta file is delivered to users meeting access control criteria which, when combined with the incomplete/partly corrupted parts allows a complete and uncorrupted version of the media file to be re-constructed. The method allows, in one implementation, a secure music purchase system to operate over digital radio: for example, the start of a song when played over the radio is usually deliberately talked over and the end cut short to prevent listeners being able to record a complete copy. With the present system, this practice can continue, but listeners can also purchase the missing or corrupted sections to enable them to possess a complete and uncorrupted version for playback.

12. A method of receiving a digital media file at a receiving device, the media file being held at a remote source as a master version divided into a first series of time frames and second series of different time frames, the method comprising the following steps:
-
a) receiving at the receiving device the first series of time frames, the first series capable of being used by the receiving device to form a version of the media file which is incomplete and/or corrupted;
b) receiving at the receiving device the second series of time frames, the second series capable of being re-combined by the receiving device with the first series to form a version of the media file which is complete and uncorrupted, in which access to the second series is only possible if the receiving device satisfies defined access control criteria;
wherein the receiving device automatically records a defined time period of the first series of time frames irrespective of any user selection of a record function of the receiving device; and
wherein the defined period is adequate to enable a user to record an entire media work even though the user only selects the record function of the device substantially after commencement of receiving the media work. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. An apparatus for processing a digital media file, the apparatus programmed to:
-
a) divide a master version of a digital media file into a first series of time frames and a second series of different time frames;
b) send the first series of time frames, the first series capable of being used at a receiving device without any form of access control to form a version of the media file which is incomplete and/or corrupted;
c) send the second series of time frames, the second series capable of being re-combined at the receiving device with the first series to form a version of the media file which is complete and uncorrupted, in which access to the second series is only granted to users satisfying defined access control criteria;
wherein the apparatus automatically records a defined time period of each of the first and second series of time frames irrespective of any user selection of a record function of the apparatus; and
wherein the defined period is adequate to enable a user to record an entire media work even though the user only selects the record function of the device substantially after commencement of receiving the media work. - View Dependent Claims (20, 21)

22. An apparatus for receiving a digital media file at a receiving device, the media file being held at a remote source as a master version divided into a first series of time frames and second series of different time frames, the apparatus programmed to:
-
a) receive the first series of time frames, the first series capable of being used to form a version of the media file which is incomplete and/or corrupted;
b) receive the second series of time frames, the second series capable of being re-combined with the first series to form a version of the media file which is complete and uncorrupted, in which access to the second series is only possible if the receiving device satisfies defined access control criteria;
wherein the apparatus automatically records a defined time period of each of the first and second series of time frames irrespective of any user selection of a record function of the apparatus; and
wherein the defined period is adequate to enable a user to record an entire media work even though the user only selects the record function of the device substantially after commencement of receiving the media work. - View Dependent Claims (23, 24, 25, 26)
