Summary

The Hauppauge HVR-955Q Linux Driver is designed to provide a high-quality solution for existing TV tuner products. A specific emphasis is given on supporting commercial embedded applications including fitness equipment, healthcare solutions, and digital signage.

Leveraging our extensive experience writing Linux TV drivers (both open source drivers and commercial), the product seeks to take into account the specific needs of commercial organisations as opposed to casual end-user TV watching. Thus a focus has been placed on ease-of-installation, providing reliable and consistent builds, supporting multiple kernels/platforms, and actively working to ensure interoperability with the common media toolkits used by integrators to provide support for TV reception and display in their equipment.

Tools and integration services are available to ease the integration of any of the tuners into existing products.
