Abstract: Folding apparatus and systems are described for providing multi-folded products utilizing a folding board having at least one pressurized nip positioned proximate the folding operation. A folded product is directed through a first pressurized nip, comprising a roller and a first surface of a second folding board, positioned upstream of the folding operation and a second pressurized nip, comprising a roller and a second surface of the folding board, positioned downstream of the folding operation. Positioning pressurized nips proximate the folding operation improves the integrity of the folds created within the product and also creates distinct, uniformly oriented fold lines.

Abstract: In a network of interconnected multimedia source, transfer, and sink ports, the described subject matter defers port parameter selection until substantially all relevant information is available. Specifically, parameters are negotiated between multiple ports by specifying parameter sets corresponding to the ports. Each parameter set is expressed as a list of constraints on allowable values or ranges of values. When connecting multiple ports, the constraints on their parameter sets are conjoined to form a parameter set intersection. The parameter sets of the ports are limited to values included in the parameter set intersection. Parameter sets relating to other ports are potentially limited based on the intersection results. The conjoining and limiting operations are repeated until the various parameter sets exhibit no further limitations in response to further repetitions. This process is repeated for all port interconnections.

Abstract: Components in a system have interconnectable ports, groups of which are to be interconnected. A method of negotiating negotiable parameters between a plurality of the ports includes specifying parameter sets corresponding respectively to the ports. Each parameter set is expressed as a list of constraints on allowable values or ranges of values. When connecting a group of ports, the constraints on their parameter sets are conjoined to form a parameter set intersection. The parameter sets of the ports are then limited to those values included in the parameter set intersection. In addition, parameter sets relating to other ports are potentially limited based on the results of the intersection. The conjoining and limiting steps are repeated until the various parameter sets exhibit no further limitations in response to further repetitions, and this process is repeated for all port interconnections. Subsequently, values for the negotiable parameters are selected from the limited parameter sets.

Abstract: A method is described for synchronously rendering digitized media streams. Each digitized media stream is made up of a sequence of media samples having media-specified timing. The described method includes calculating presentation times for media samples of different media streams based in part on the media-specified timing of the media samples and also based in part upon the desired synchronization of the different media streams relative to each other. The calculated presentation times indicate when the media samples should be rendered relative to a common clock reference. The method further includes attaching a media sample's calculated presentation time to the media sample, and then routing the media sample to a sink component for rendering. The sink component renders the respective media samples of the digitized media streams at the approximate presentation times of the samples relative to the common clock reference.
