The High Definition Multimedia Interface® (HDMI) has come to dominate the consumer electronics industry as the de-facto interconnect for carrying audio and video data in digital format between system components.

MDS offers a range of standard OEM modules for HDMI switching/repeater functions that allow audio system developers to use a standard product for the HDMI I/O and focus their efforts on their audio system (and for those looking for less development effort MDS offers complete audio processing solutions with our DAE series).

HDMI involves signaling at 3.0 GHz rates with current generation parts, and rises to 6.0 GHz in the next generation. Compared to the older S/PDIF digital audio link at 12 MHz, special techniques are needed to ensure reliable data transfer at the rates found in HDMI systems.

Unlike prior interface standards,  HDMI is also combined with a content encryption scheme, HDCP, that increases the hardware and software complexity as well creating interoperability problems over the basic HDMI data carrying interface requirements. To ensure the minimum amount of problems, MDS performs its own extensive testing as well as attending industry-wide “HDMI Plugfests” to ensure inter-operability against a wide range of vendor equipment.

MDS has extensive expertise on HDMI systems and in addition to standard stock products offers consulting services and design licensing to designers seeking to reduce development time, cost, and risk.  MDS has specific expertise with Analog Device’s and Silicon Image HDMI parts, but our general knowledge of HDMI can be applied to any manufacturer’s parts.
