Abstract: An initialization vector (IV) is employed to decrypt a block of a stream that has been encrypted with Cypher Block Chaining (CBC) encryption, without requiring decryption of previous blocks within the stream. For example, a listener who accesses a distribution point to retrieve encrypted content authenticates himself to an application server that regulates access to encrypted content on the distribution point, and responsively receives a key. The listener then requests access to a reference point within the encrypted content stream somewhere after its beginning (e.g., using preview clips). The distribution point relates the reference point to a corresponding block of the encrypted stream, and identifies an IV previously used for encryption of that block. The distribution point provides the associated encrypted block of content and the IV to the listener to enable mid-stream rendering of the encrypted content, without requiring the listener to decrypt previous blocks within the encrypted stream.

Abstract: The invention provides a method and system for distributing personalized content to potentially large numbers of recipients. A pool is selected, from among all content available for distribution, of those content elements that will be made available for simultaneous distribution, and personalized content is selected for distribution from that pool. The content of the pool can change with new selections over time. For each individual recipient, content elements in the pool are examined to determine if they are predicted to be of sufficient interest to that recipient for distribution, and if so, those content elements are distributed. If not, successive content elements in the pool are examined, relaxing the standard for sufficient interest, until at least one content element is found and distributed to the individual recipient.

Abstract: In order to increase the efficacy of a mood-based playlisting system, a mood sensor such as a camera may be used to provide mood information to the mood model. When the mood sensor includes a camera, a camera may be used to capture an image of the user. The image is analyzed to determine a mood for the user so that content may be selected responsive to the mood of the user.

Abstract: A method for identifying a result responsive to a current location of a client device includes receiving, form a client device and at a host, a search query that includes a point of interest and a current location of the client device. The method also includes automatically updating the search query as the current location of the client device changes and instructing the host to identify a potential location associated with the point of interest and located within a user-defined proximity from the current location of the client device.

Abstract: Access to an electronic conference may be administered by receiving an electronic instruction configured to establish the electronic conference, enabling more than one user to generate content restrictions that limit content rendered during the electronic conference, analyzing one or more participant devices to ensure compliance with the content restrictions, establishing the electronic conference in accordance with the content restrictions, and enabling user access to the electronic conference consistent with the content restrictions.

Abstract: A first device may communicate by joining a wireless mesh network that includes at least one wireless device configured to operate a wireless routing protocol, discovering a group of other wireless devices configured to participate in the wireless mesh network, and accessing an interest metric for a second wireless device in the group of other wireless devices. The interest metric is based in part on a network topology from the wireless mesh network. The interest metric is related to an interest threshold and it is determined whether relating the interest metric to the interest threshold supports enabling messaging communications. If so, messaging communications may be enabled.

Abstract: The digital content store provides users with an opportunity to purchase authorized usage of digital content, such as single or multiple music tracks, video, movies, and/or video games. The users can also buy license to a desired track for a fixed number of times, e.g. preferably the users can listen on three different machines simultaneously. Users can also burn a play list of X number of times, for example ten. The burn limit preferably applies to the play list, not the song. Mixed media capability is provided that allows the purchase of digital content and/or physical media. The digital content store system comprises a unique digital rights management system and a back-end enabling system that controls these digital rights.

Abstract: Advertisements may be inserted into a streaming video at an intermediary system by receiving a data stream including a video content selection having scenes configured to accommodate insertion of advertising objects, identifying an advertising descriptor based on characteristics of a scene within the data stream, selecting an advertising object based on the identified advertising descriptor, modifying the video content selection by inserting the advertising object in the data stream such that the advertising object is integrated into a scene of the video content selection, where an image scene of the video content selection is modified to integrate and enable visual display of content from within the scene of the video content selection and the advertising object concurrently, and transmitting the content selection to a recipient.

Abstract: A distribution of a content selection being distributed throughout a wireless mesh network may be tracked. A wireless device in the wireless mesh network enables the content selection to be exchanged. Wireless devices then exchange the content, and a network topology is recorded in response. Finally, the network topology is reported to a reporting agent.

Abstract: A switch having a first communications interface to receive a stream of data units, a buffer to store the payload portion of the data unit, a replicator to duplicate at least the payload portion of the data unit, and a second communications interface to enable access to the stream of data units by two or more terminals.

Abstract: A user's access to content may be managed by determining a mood originating point for a present track for a user, with the mood originating point being related to a mood indicator for the present track, identifying a mood destination for a user playlist, the mood destination being related to a mood indicator for an end track that is targeted for the user, and calculating a mood transition from the mood originating point to the mood destination. The mood transition includes one or more intermediary tracks between the mood destination and the mood originating point, such that a quantified mood transition between two tracks in a user playlist including the present track, the intermediary tracks, and the end track, is less than an identified mood transition threshold.

Abstract: Generally, a mood-based playlisting system may select content to maintain a mood consistency between selections of content. In one example, electronic content may be made available to users by determining a mood indicator indicating a present mood state of a user, determining a mood spectrum describing mood indicators that are consistent with the mood indicator for the track, and selecting a next track having a mood indicator that lies within the mood spectrum. In another example, content may be selected by determining a coordinate mood location indicating the present mood state of a user, determining a compatible mood volume indicating potential mood indicators for a next track that is compatible with the present mood, identifying one or more tracks having mood indicators that lie within the compatible mood volume, and enabling the user to access one or more of the identified tracks.
