Abstract:
A system and method for selling software products over a network. The system includes a server computer with access to software products. The system is configured to allow a user to purchase a subscription for the periodic acquisition of selected software products. In one embodiment, as part of the subscription, the user pays an amount during selected billing intervals. In return, the system issues to the user a number of credits for downloading at no additional charge at least one of the software products during a credit interval, which may be equal in length to the billing interval. In one embodiment, the system debits a number of credits in response to fulfilling a user's purchase request. The system may be also configured to deduct credits that are not used within selected credit intervals.
Abstract:
A number of digital content rendering modules are equipped such that selective subsets of the modules may be employed to render digital content of different media, and of different format types. The modules are organized into a hierarchy, with a selected one occupying a root position of the hierarchy, to exclusively receive the digital contents to be rendered, and that each module is further responsible for verifying the integrity of its immediate downstream modules, to collectively protect the digital contents being rendered. Additionally, in accordance with another aspect, a tamper resistant module is employed to recover digital contents provided in a protected state, obfuscating the recovery. Further, the modules may be of different application domains.
Abstract:
A communications system and method provide a seamless switch from a first session to a plurality of multicast sessions. A server transmits data over both a first session and alternatingly between a plurality of synchronized multicast sessions. At predetermined time intervals, the server stops transmitting data over the currently active multicast session and starts transmitting over an idle multicast session. The server is further responsive to a request to stop transmitting the data over the first session at a time when the server alternates transmission between the multicast sessions. The time intervals are advantageously sufficient to allow a receiver to join an idle multicast channel and to send a request to stop the data transmission over the first session.
Abstract:
A method and apparatus for preserving matrix-surround information in encoded audio/video includes a receiver operative to receive matrix-surround encoded audio signals via a modem, separate the audio signals into a frequency spectrum having discrete audio frequencies, and determine a cutoff threshold used to encode the matrix-surround encoded audio signals. The method and apparatus further includes a decoder operative to decode a first set of the audio frequencies below the determined cutoff threshold using a first matrix-surround preserving audio encoding method and to decode a second set of audio frequencies above the cutoff threshold using a second non matrix-surround preserving audio encoding method.
Abstract:
A system for determining selections that a user is likely to be interested in. The determination is made based on the user's prior indicated preferences. The user designates his or her preferred selections as entries in a user's preference list. Entries in the user's list are compared with entries in the other users' lists. When a significant number of matches have been found between two lists, the unmatched entries of the other user's preference list are extracted. The unmatched entries are further processed. Those unmatched entries with a high correlation to the user's preference list are presented to the user as selections in which the user is likely to be interested.
Abstract:
A media distribution system, method, and computer program product for storing a plurality of media data files within a media repository. One or more of the plurality of media data files are identified within a file catalog. A data request is received, using a standardized protocol, from a client electronic device. Data is provided, in response to the received data request, to the client electronic device in a third party usable format. A user of the client electronic device is enabled to browse/search the file catalog and identify one or more media data files chosen from the plurality of media data files.
Abstract:
A method and apparatus for dynamically managing data-type associations and relationships includes providing a first global data-type association ruleset including one or more predefined operational relationships between two or more applications, determining whether an updated global data-type association ruleset is available, and dynamically obtaining the updated global data-type association ruleset to facilitate modification of one or more predefined operational relationships between two or more applications locally installed on the client device.
Abstract:
A method, computer program product and computing device for receiving a text search request from a user. A text datastore is searched using the text search request to identify a matching text data file/segment chosen from a plurality of text data files/segments. At least one media data file associated with the matching text data file/segment is identified, the matching text data file/segment being at least a partial transcription of words within the at least one media data file.
Abstract:
Transform coefficients of sample blocks of a macroblock of a video picture are encoded by adaptively encoding a combination, the number of non-zero coefficients before the trailing one coefficients and the number of trailing one coefficients. The transform coefficients may be further encoded by adaptively encoding one or more of the signs of the trailing one coefficients, the level measures of the interposed in the non-zero coefficients. Adaptive encoding of the number and trailing one coefficients may be performed in view of one or more neighboring sample blocks, whereas adaptive encoding of level measure may be performed in view of quantization parameters of a macroblock and previously encoded level measures. Decoding may be performed in an inverse manner.
