     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of Invention 
         [0003]    The present invention relates to multimedia systems, and in particular personal multimedia systems used to form libraries of multimedia including video and audio files. 
         [0004]    2. Description of Related Art 
         [0005]    In today&#39;s environment it is important to use commercially produced multimedia, i.e. analog and digital video, DVD&#39;s and CD&#39;s, in a manner consistent with industry license standards. Building personal libraries often consists of a rack of DVD and CD disks that are separately loaded into a player having one or more slots to hold the disks. Unless an individual creates a cataloging scheme, it is sometimes difficult to find a particular DVD or CD. Once a DVD containing a movie has been viewed, reviewing may not be as frequent as listening to a CD containing favorite music and the library of DVDs grows without frequent reuse. 
         [0006]    A solution to the growing DVD library, which consumes space and requires physical organization, is to store video content into a personal video library and index the videos for future use. A user verification and a rights verification included in the personal video library guarantees the storage and use of the video&#39;s according to industry license standards.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0022]    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. 
         [0023]    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&#39;s ID and the specific title of the commercial video. 
         [0024]    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. 
         [0025]    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 . 
         [0026]    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. 
         [0027]    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. 
         [0028]    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. 
         [0029]    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&#39;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. 
         [0030]    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. 
         [0031]    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.
