  • the device 10 may include a supply unit 55 that is operable to store memory devices, such as RSDs. If desired by the user, the device 10 may store a requested data set on a memory device present in the supply unit 55 and subsequently dispense the memory device to the user. As such, a user without a storage medium but wishing to obtain a data set may purchase both the data set and the storage device on which the data set is stored from the device 10 .
  • the device 10 after identifying the requested data set and the target storage medium indicated by the user, may determine that the target medium has insufficient storage space or is otherwise unsuited to receive the requested data set.

  • a decoding data set that, when executed, operates to decode the requested data set, thereby enabling presentation of the requested data set.
  • the device 10 may otherwise provide digital rights management (DRM) and content protection for all the contained and dispensed content by employing systems already in place for content protection/DRM such as that standardized by Internet Groups and the International Telecommunications Union (ITU). Every data set dispensed will contain its own serial number so that unauthorized use may be traced and prosecuted. The serial number cannot be changed without at the same time erasing as least some of the content of the data set.
  • the data sets transmitted to the customer's storage media device may also be constrained to play from that device only. If the attempt is made by the customer to copy the media onto any other storage than that originally dispended onto, the media will not play.
  • a content anti-copy mechanism may be used when writing content to memory cards, whereby the serial number of the memory device is utilized. This process requires that the serial number of the card be read by the device 10 and then written onto the card as part of the data set, as well as loaded with the data player/decoder on the card.
  • the card data be subsequently copied on to another medium such as a second programmable flash card
  • the files would not play since the new card would have a different serial number from the original.
  • the card would act as a dongle preventing play of the data by its own self-contained player.
  • Use of video players on a playing device e.g., cell phone) would not permit this manner of anti-copy protection.
  • the number of plays that will be allowed for a given price may be accommodated by the device 10 , such that, for example, a rental movie can be played but once (or N times) as contrasted against a music video which would normally receive unlimited plays.
  • This limitation whereby the number of plays may be limited in a pay per view application may be achieved by utilizing rewritable cards such as flash memory cards. Read-only and write once flash cards may not be employed for this method.
  • the device 10 may, when reading a card, be able to determine whether the card is a multi-time programmable card. In the event that the card is programmable, the software associated with the player accompanying the data set will implement a count down on play cycles and write the same to the card upon the completion of each play. When the N-views have been counted for which N was paid, the player will limit the plays to that specified by reading and comparing the counts written on the card. The player may, after this limit has been reached, scramble the original data file.
  • the device 10 may automatically recognize and utilize storage areas on the storage device/card which have been previously used for content for which use has now expired.
  • the device 10 will allow a customer to block files from being overwritten with new content by, for example, allowing the customer to specify the memory portions into which content should be written.
  • the client device 30 and device 10 may respectively include more or fewer than all of the components illustrated in FIG. 2 .
  • the device 10 and client device 30 may omit the port 80 .
  • FIG. 3 illustrates a process of providing a data set according to an embodiment of the invention.
  • a user wishing to receive a data set provides an indication of his/her data set selection to the device 10 .
  • the device 10 determines if the user is authorized to receive the data set (i.e., whether the user has paid for the data set).
  • the device 10 determines whether the user has identified an appropriate target memory device or whether the user requires additional or other equipment.
  • the device 10 accesses the requested data set.
  • the device 10 stores the requested data set on the target memory device.
  • the device 10 may dispense content encoded in technology other than that employed in DVD movies or on CD players.
  • the decoder contained with a data set is utilized by the general purpose processor of the computing platform to decode and render the video/audio and must be adaptable to operating system and “playing platform” CPU and video configuration.
  • the decoder will not be specified for any particular “standard’ and may be anything which renders good quality.
  • the owner or administrator of the device 10 may provide for the encoding of the data and provide DRM/content protection to the satisfaction of the content owner/licensor. Provision may be made for license fees/per dispensation to be collected by the device 10 owner and paid to the content owner.
  • Inexpensive rewriteable digital memory forms promote implementation of embodiments of the invention described herein. Principally flash memory and its successors, which were pioneered for digital cameras, have now penetrated into the computer memory field and are the storage form of choice for portable applications as evidenced by their embrace by PDA's, cell phones, and now are the desktop/laptop portable storage form of choice. Capacities on the market already are in the 4 GB/device range, enough to accommodate many movies at a time. The I/O data rates of these memories are also already such that a 90 minute movie could be loaded from the device 10 onto a memory within a matter of less than 10 seconds at the nominal rates (400+Mbps). Not all memory forms may be that rapid, and may require more time to load a 90-minute movie. Locks known in the art that prevent removal of consumer storage devices absent an unlock code or physical security identification means, such as a key, may be provided in connection with the device 10 , and allow the consumer to walk around the store, e.g., supermarket, during the content download.
  • High speed general purpose computing processors with video output capability now exist in all computing platforms, such as desktops, laptops, PDA's and cellphones. Some devices are already on the market for reading memory cards and converting the output for input to a TV set (e.g., Vosonic Digiviewer 3020).
  • Computer program code for carrying out operations of embodiments of the present invention may be written in an object-oriented programming language, such as JAVA, Smalltalk, or C++.
  • Computer program code for carrying out these operations may also, however, be written in conventional procedural programming languages, such as the C programming language or compiled Basic (CBASIC).
  • CBASIC compiled Basic
  • some modules or routines may be written in assembly language or even micro-code to enhance performance and/or memory usage.
  • at least one carrier signal may be modulated with computer program code for carrying out the described operations.
