Abstract: Techniques for distributing restricted media to consumers are disclosed. According to one aspect of the present invention, personalized settings (e.g., parameters or table) are managed in a primary client device associated with a user. A copy of the personalized settings is maintained in a server. When the primary box is replaced, a copy of the personalized settings is uploaded to a different client device that is configured to respond to the personalized settings. Data pertaining to titles in a personal vault is preloaded. When there is an order for a release that is restricted for distribution over an open network, data pertaining to such a release is also loaded. As a result, the subscriber sees the familiar settings on the different client device and would not miss any release while the primary box is being replaced or repaired.

Abstract: A system, machine-readable medium and method for processing video comprising a video segmentor configured to receive a source video and to split the source video into segments; a bit rate allocator configured to receive the segments and generate target bit rates corresponding to the segments; a first encoder coupled to receive the plurality of segments and the target bit rates and configured to encode each of the segments using one of the target bit rates to generate encoded segments; and an output generator configured to receive the encoded segments and generate an encoded video.

Abstract: Methods of optimizing access to a relation queried through a number of predicates. The methods identify one or more candidate predicates of the selection condition that can be used to factorize the selection condition. A gain from using one or more of the candidate predicates to factorize the selection condition is computed. One or more of the candidate predicates that result in a positive gain are factored from the selection condition to produce a rewritten selection condition. The candidate predicates can be predicates that appear exactly in the selection condition more than once and/or merged predicates that may be predicates in the selection condition that overlap.
