Abstract:
PROBLEM TO BE SOLVED: To provide a method for distributing content over a network. SOLUTION: In the method, a media storage structure including a first content section for storing first pieces of encrypted content and a second content section for storing second pieces of encrypted content includes a first key section and a second key section for storing the first and second keys, respectively for making the first and second pieces of encrypted content plain text. The media storage structure is distributed from a computer different from one or a plurality of computers for distributing first and second keys, and the first and second keys are inserted into first and second key sections in the media storage structure. Based on the keys, either or both pieces of encrypted content between two pieces of content in the media storage structure are made into plain text to make the content accessible.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and a system for network-based purchase and distribution of media. SOLUTION: The purchase and distribution of media by the method and system are not only secure but also controlled. The security restricts access to media within media files during downloads as well as while stored at a server and/or client. Upon purchasing a media item, the content for the media item can be downloaded over the network to the purchaser. The content for the media item is then encrypted for the purchaser's use and stored on the purchaser's machine. Thereafter, the purchaser can make use of the media item (e.g., play the media item). Improved graphical user interfaces suitable for reviewing, browsing, previewing and/or purchasing numerous media items are also disclosed. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
Methods and systems that improve the way media is played, sorted, modified, stored and cataloged are disclosed. One aspect relates to a browse window that allows a user to navigate through and select images that are related to media items. Another aspect relates to a graphical user interface of a media management program that utilizes multiple browse windows. Another aspect relates to simultaneously displayed media browse windows whose operations are integrated together so that the content shown therein is automatically synchronized when selections are made. Another aspect relates to resetting browsed content to the currently playing media.
Abstract:
Some embodiments of the invention provide a method for distributing content over a network. The method distributes a single media storage structure to a device (e.g., a computer, portable player, etc.) that connects to the network. The media storage structure includes first and second pieces of encrypted content. Based on whether the device is allowed to access the first piece of content, the second piece of content, or both, the method provides the device with a set of keys for decrypting the pieces of the content that the device is able to access. The provided set of keys might include one or more keys for decrypting only one of the two encrypted pieces of content. Alternatively, it might include one or more keys for decrypting both encrypted pieces of content. For instance, the selected set of keys might include a first key for decrypting the first encrypted piece and a second key for decrypting the second encrypted piece. Based on the provided set of keys, the device can then decrypt and access either one of the two pieces of content in the media storage structure or both pieces of encrypted content in the media storage structure.
Abstract:
There is provided a method of a user receiving permission to access media content comprising receiving a unitary media storage structure with a plurality of protected media portions, receiving from a license authority a key for each protected media portion that the user has permission to access, and using the respective key to access each protected media portion that the user has permission to access.

Abstract:
A method and system for network-based distribution of content are disclosed. The distribution of content is not only secure but also controlled. The security restricts access to content within media files during downloads as well as while stored at a server or client. In one embodiment, each media file is encrypted with a different, randomly generated key. The control over the distribution of the media file can serve to limit the subsequent distribution of media files from clients to other clients. In another embodiment, the control can permit media files to be shared on a limited number of different clients affiliated with the same user. The clients can vary with application but generally are computing devices that have memory storage. Often, the clients are personal computers or other computing devices that are capable of storing and presenting content to their users
