ON THIS PAGE

The 4K series is a line of commercial-grade solid-state media players that can be used to decode images, audio, and video (up to 3840x2160x60p) for digital-signage and kiosk applications. In addition to driving audio/video devices, these players can be controlled with various networked and built-in interfaces.

This section specifies the hardware interfaces and operational theory of the 4K series.
