A method for distributing non-transactional workload in the form of online analytical processing (OLAP) load across multiple database servers comprises receiving, at a scheduler server, a plurality of asynchronous work requests, adding, by the scheduler server, each of the received asynchronous work requests to a work list queue as a work item, and determining, by a scheduler module of the scheduler server, a first work item from the work list queue to select for performance by the first thread of the application server. In accordance with one or more preferred implementations, the first work item is selected utilizing a methodology which determines a number of work items in the work list queue having a processing status that are assigned to a database server, and based thereon determines whether an additional work request can be assigned to that database server without exceeding a request threshold for that database server.

The present invention provides an architecture for translating closed captioning text originally provided with a video program from one language to another and presenting the translated closed captioning text with the video program to a viewer. As such, the viewers are able to receive the closed captioning text in languages other than that used for the closed captioning originally provided with the video program. The original closed captioning text may be translated from one language to another by a centralized closed captioning processor, such that the customer equipment for various subscribers can take advantage of centralized translation services. Once the original closed captioning text is translated, the translated closed captioning text may be delivered to the customer equipment in different ways.

One embodiment of the present invention facilitates efficient metering in a packet network environment by providing a single metering message, which contains sufficient information to provide the complete call tariff model for a particular call. The media gateway receiving the message can analyze the information provided in the message to determine how to provide metering pulses for all phases of the call, as well as any one-time charges, such as setup and add-on charges. Another embodiment of the invention provides a way for handling fractional pulse counts in an efficient manner. Yet another embodiment facilitates the handling of situations where charge intervals do not divide evenly into the phase duration of the phase associated with the call. In still another embodiment, the amount of information necessary to deliver the parameters of the call tariff model is minimized to reduce the overhead necessary for facilitating the metering process.
