Presentation Switchers, Inc. (PS) designs, manufactures, and market high quality, innovative, and automated digital presentation systems. Throughout these products, PS has developed technologies including, but not limited to, HDMI switching, analog-to-digital AV conversion, decoding, video scaling, EDID management, audio extraction, and HDCP video decryption. Signal types include HDMI, VGA, DVI, DisplayPort, Component, Composite, Stereo Audio, Mono, and Amplified Stereo (70V, 100V, and 25V). We have developed these technologies to provide distinct, niche-oriented solutions for our customers and the markets we service.

Other manufacturers recognize that developing these capabilities is both time-consuming and costly. Instead of developing and debugging these technologies themselves, manufacturers contract PS to develop products under their own brand name. PS is referred to as the original equipment manufacturer (OEM). PS design and develop these products in their Spokane location. Production, assembly, and testing may occur either in the United States, some other country, or a hybrid of the two as required by the contracting manufacturer.

These development services include mechanical product design, schematic development, board layout, firmware programming, production, assembly, and testing.

Mechanical Product Design

Often beginning with a simple sketch, PS will produce a complete SolidWorks™ 3D model of the product. The model allows PS and the manufacturer to "fly through" the product and explore how the product will look and be assembled. Opportunties abound to discuss clearances, cooling, and value-engineering. Once approved, PS creates a full 2D set of fabrication drawings which are then sent to metal/plastic fabricators for quoting.

Schematic Development

In parallel to the mechnical processes, electrical engineers begin the schematic design work. This means defining the selection of electronic components and connectors, laying out audio and video signal paths, power for the components, and determining methods of controlling the product. This is no small task. The completed schematic enters board layout where the artwork is created in preparation for the printed circuit board (PCB).

Software Engineering

After the PCB has been created, software engineers develop firmware or the internal software to control the product. This process is often quite involved depending upon the scope of the project and involves programming certain electronics within the product. Frequently, PS will reuse (recycle) firmware already designed, developed, and debugged for certain audio-visual and control technologies. At this stage, prototyping begins and the manufacturer (customer) tests the product to ensure the product meets or exceeds agreed upon specifications.

Assembly & Testing

The production phase of the development cycle involves the procurement, assembly, and testing of the finished product. As stated above, these processes may occur in the United States or in other parts of the world. For example, a manufacturer may choose to have some parts built in the United States to meet government contracting requirements. The same part could be produced in Europe and China to meet production requirements in each global region while minimizing shipping costs. PS has contract manufacturers in most major regions of the world and can easily facilitate these production requirements.
