DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
In FIG. 1 is shown a coupling between the personal video depot (PVD) 12 of the present invention and a server 10. A network 11 is used to couple the server 10 to the PVD 12 through a network interface port 13 of the PVD. The network can include a variety of networks comprising the internet, a cable network and a satellite network. When the server is contacted by the user of the PVD, a selection of a video title is made available for purchase and is downloaded to the PVD of the user.
Shown in FIG. 2 is a block diagram of the PVD 12. The content capture unit 20 captures video content from external sources, i.e. networks such as internet, cable and satellite, DVD disks, and personal movies created by personal video cameras. The content capture unit 20 reads in digital video content from digital sources such as a network interface port connected to a server and a DVD, and digitizes, compresses and encrypts analog video into a standard compliant digital video such as MPG2. The content capture unit is managed by the rights verification and assignment unit 21 to comply with commercial license control mechanisms. The video content coupled with the proper rights assignment information is recorded into the storage system 23 controlled by the content file system 22. Each viewing of a video from the service portal or DVD input to the PVD 12 requires authentication of the user 24, which is accomplished by the use of a smart card, a personal identification number or similar means. Each commercial video obtained from the server or separately purchased DVD is encrypted with a license key that is unique to the user's ID and the specific title of the commercial video.
Continuing to refer to FIG. 2, the user authentication unit 24 is used to verify the identity of the user using various methods comprising a smart card, an entry of a PIN (personal identification number) with the key pad of a remote control unit 29 which operates the PVD of the present invention. This allows the user to protect his/her library of video files and prevent unauthorized use including the copying of video files from the library as well as identify the user as being authorized to use the video content stored within the PVD. The user authentication 24 is also important for identifying the user to the server 10 when purchasing video tiles to be downloaded from the server. If ownership of a particular video content is to be copied to a second user, the second user is required to identify himself/herself to the system using a smart card, pin number or similar means. The rights verification and assignment unit 21 verifies that the user has the right to download new video content, play a video resident in the storage unit. If a second user wants a copy of a video, the second user must have his/her identification authenticated by the use of a smart card or pin number associated with the second user, whereby a fee is paid by the second user for the video copied from the first user. The second user assumes ownership of the copy taken from the first user.
The storage system, comprising the content file system 22, the internal storage system 23, the external storage interface 25 and an external storage device 26, organizes the video data to provide flexibility in the usage of the data and to insure the security of the video data. As shown in FIG. 3, each video file in the storage system comprises the rights assignment 30 from the rights verification and assignment unit 21 and the video content 31, which is a bit stream copy of the encrypted video originally entered into the depot, coupled with further necessary encryption based on rights assignment 30.
Continuing to refer to FIG. 2 the TV interface unit 27 allows the user to operate the PVD 12 of the present invention with a TV set using a GUI (graphical user interface) displayed on the TV screen and a remote control unit to select from the menu in the GUI. The player device interface unit 28 allows other player devices, i.e. DVD player/recorder or a PC (personal computer) to play a video stored in the PVD 12 of the present invention in which the PVD 12 becomes an authenticated security sensitive storage device.
The internal storage device 23, comprising a hard disk drive, a flash memory or other similar nonvolatile storage medium, is used to store videos within the PVD that have been rights verified by the rights verification and assignment unit 21. This storage capability can be expanded through an external storage interface 25 coupled to the content file system 22 using a coupling medium comprising USB (universal system bus), IEEE 1394 connection means or similar connection technology. The external storage device 26 comprises a hard disk drive, flash memory or other nonvolatile storage medium.
The player device interface 28 allows other player devices, i.e. a PC (personal computer), a DVD player and similar electronic equipment to play videos stored within the PVD. The PVD becomes an authenticated source and security sensitive storage device of video files similar to a DVD or a USB hard disk.
In FIG. 4 is shown a method of the present invention for purchasing and downloading a video in digital form from a server. The user is authenticated 40 by using a smart card, a personal identification number (PIN) or similar identification means. Using the remote 29 to select from a menu on a TV screen, the user commands the PVD to contact a server 41. The server verifies the user and the user's account 42. The server returns a menu of available video titles from which the user selects a desired title. Once the title has been selected using the remote device 29, the user commands the PVD to request the server to download the video 43. Upon receipt of the video, a rights verification and assignment is performed 44 which assigns the rights to the user to be able to use the video for the purposes of the user. Upon completion of the rights verification and assignment, the video content 31 and the rights assignment 30 are stored in the storage device of the PVD. The PVD can also assign rights to an ingested DVD purchased separately through the server and upon completion of the rights assignment store video content from the DVD along with the rights assignment. As long as the user uses the downloaded video or the DVD for personal means, the assigned rights are valid and do not need to be re-verified.
In FIG. 5 is shown a method for using the PVD of the present invention. Either a video is purchased from a server 50 coupled to the PVD or a purchased DVD is ingested 51 into the PVD. The user ID is authenticated 52. The rights verification and assignment is performed on the video purchased from the server or the ingested DVD and stored with the purchased video from the server or the purchased DVD. The server purchased video or the DVD are played on a TV coupled to the PVD 53. The user of the PVD has an option to copy the video purchased from the server to a DVD 54 and to copy the purchased DVD to an additional DVD 55. Many different licenses and payments schemes could be implemented based on this framework. For example: In the case of a video purchased from the server, a first copy of the purchased video is made without a fee and a second or subsequent copy of the video purchased from the server is assessed a fee. In the case of the ingested DVD, a second or subsequent DVD is copied for a fee that is different for the user of the PVD than for individuals that are not the registered user of the PVD.
While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made without departing from the spirit and scope of the invention.
