    摘要: A method for generating an oscillator signal uses a multiphase oscillator having a plurality of input stages and a reference stage. Each input stage produces an input stage voltage that represents a phase for the oscillator. The input stage voltages produced by each of the input stages are compared to a reference voltage produced by the reference stage. An input stage having a maximum input stage voltage is selected and an output of the selected input stage having the maximum input stage voltage is changed. A current need of the oscillator is detected with a negative feedback loop coupled to the reference stage. An appropriate supply current is provided to each input stage with the negative feedback loop.

    摘要: Techniques are provided for more efficient multi-row atomic, consistent, isolated and durable (ACID)-compliant transactions with snapshot isolation semantics (or just “multi-row transactions” for short). In some embodiments, the techniques are implemented in a computing system that includes a client application, a lightweight in-memory lease-based lock service, a multi-row transaction orchestrator, and an underlying database system. The transaction orchestrator implements a read protocol and a write protocol that provides support to the client application for carrying out multi-row transactions against the underlying database system irrespective of whether the database system itself supports multi-row transactions. The transaction orchestrator explicitly maintains transaction-level locks obtained from the lease-based lock service as part of the transaction protocol. Further, the transaction orchestrator is tolerant to lock service failure and unavailability without compromising ACID-compliance and snapshot isolation guarantees to the client application.

    摘要: Multiple channel maps are embedded in a television transmission and the appropriate channel corresponding to the particular television service used by the viewer is downloaded for use with the television receiver. Each channel map is accompanied by a channel map identifier which identifies the source of the television transmission and a geographic identifier. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. The geographic area identifier is determined by comparison with a user inputted geographic area identifier. The channel map having a channel map identifier corresponding to the detected television transmission source and the user inputted geographic area identifier is downloaded and stored for future use.

    摘要: Multiple channel maps are embedded in a television transmission and the appropriate channel map (68) corresponding to the particular television service used by the viewer is downloaded for use with the television receiver. Each channel map (68) is accompanied by a channel map identifier (66) which identifies the source of the television transmission and geographic identifier. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. The geographic area identifier is determined by comparison with a user inputted geographic area identifier. The channel map (68) having a channel map identifier (66) corresponding to the detected television transmission source and the user inputted geographic area identifier is downloaded and stored for future use.
