Definitions

  • This invention relates to a digital pay-per use network system and, more specifically, to a local digital pay-per-use network system that is capable of operating many nodes in an independent arrangement.
  • a set-top box containing a user interface protocol of some kind.
  • the user enters information which is relayed back to the source of the signal, such as a signal source, station, an intermediate or local distribution center or a signal stored in a smart card.
  • the source of the signal such as a signal source, station, an intermediate or local distribution center or a signal stored in a smart card.
  • a smart card it may give authorization to decrypt, and at a later date transmit billing information to a central station.
  • the signal source the end user's request is accounted for, and the proper encoded signal is sent to the end user via a cable line or by satellite.
  • the return signal is processed and decoded by the end user's set-top box and is then displayed over the screen.
  • an in home pay- per-use system wherein all requests by various users for a given pay per use function are controlled in-house by a source node that controls the use and availability of the data stream information for its connected end user nodes, simultaneously and independently of each other.
  • the end user nodes may include a plurality of various user applications, such as television sets, video recorders, audio devices, and personal computers.
  • the source node is connected to at least one end user node via a serial bus in accordance with a communication protocol such as those governed by IEEE1394 or Universal Serial Bus (USB) standards. It not only independently controls the end user's ability to decode the information contained in the data stream on the serial bus, but also maintains tracking, with accounting of all of the transactions that occur at each end user node.
  • a communication protocol such as those governed by IEEE1394 or Universal Serial Bus (USB) standards.
  • the digital information contained in the data stream is transmitted in an encrypted format from a signal source, such as a cable operator, to the source node located locally in the end user's house and in turn is directed through multiple end user nodes each of which receives the entire encrypted data stream.
  • digital information could be retrieved locally from a digital storage media such as a DVD, CD or any other means of storing digital information.
  • the end user node sends a key request to the source node via the serial bus.
  • the source node then processes the information and returns a specifically addressed decryption key reply to the requesting end user node. That end user node employs the received decryption key to decode the requested information from the incoming data stream.
  • the accounting and decoding key requests are all handled locally as opposed to a distant central location. This allows users to have better control of various settings offered by the system, such as for example setting limits on use per user node, selecting appropriate content for each user node and the like. Additionally, because all of the accounting takes place locally, users can have access to more up-to-date billing information. More importantly, another novel aspect of this invention is the ability to service many separate end user nodes on a serial bus simultaneously, while providing each with separate information and accounting. End use nodes may include various equipment, such as televisions, MP3 recorders, internet related devices, and other such equipment that is able to process digital media signals.

  • source node 20 sends the decryption key to end user node 30 allowing the pay-per-use function to proceed while tracking the billing and usage time in accounting module 40.
  • local area pay-per-use system 10 can also be used in an apartment building or other multiple billing party arrangement as seen in Fig. 6.
  • This configuration works in a similar fashion however, in this case source node 20 treats each individual end user node 30 as a separate billing party, simply reporting the uses of each end user node 30 to accounting module 40.
  • each end user node 30 can be in a different apartment but they can all use the same source node 20 for decryption key requests and accounting of their pay-per-use functions. This allows for much greater ease in setting up new users on a pay-per-use system.
  • end user nodes 30 are limited only by serial bus's 50 protocol. Additional end user nodes 30 can be done as easily as Plug and Play (TM) or other such hardware recognition programs. The configuration of end user node 30 will happen automatically, governed by the protocol of serial bus 50.

  • Another embodiment contemplated by this invention is a set up with multiple end user nodes 30 through 30n where each end user node 30 is used by any one of a number of different users.
  • each user is deemed as a separate billing party and the end user nodes 30-30n are in operation simultaneously, performing various pay-per-use functions.
  • this arrangement employs for example, when different members of a household desire to track their usage of various devices in their pay-per-use system 10. As such, each member is assigned a separate ID and access code for the sam pay-per-use device.
  • the local area pay-per-use-systemlO described herein can operate without decryption technology as well, in accordance with another embodiment of the invention.
  • the signal stream via serial bus 50 may be transmitted without being encoded.

  • the use by each end user node 30 is tracked when a user requests a desired program content.
  • the desired program contents are decoded by end user node 30 without the need for any decoding keys. All the information content will then be available to all end user nodes 30.
  • Decoding is controlled only by the device. For example, an MP3 player will not decode a digital video signal and vise versa.
  • local area pay-per-use system 10 is the ability of source node 20 to simultaneously manage and account for many pay-per-use functions at multiple end user nodes 30 without requiring an individual set-top box at each device. Whether this be in the form of several devices in a single house, or one or two devices in many apartments, or even multiple public ports at a internet cafe or digital video arcade, local area pay-per use system 10 allows a single source node 20 to control the use and accounting for multiple pay-per-use functions simultaneously.
