Show Me the Next-Generation HDMI
The first part of this white paper explores the basic concepts behind HDMI, the markets it serves and its leadership role in multimedia interfaces. This is followed by a tutorial on the new capabilities of HDMI 1.4 and their role in providing a richer, more straightforward user experience. Next, we’ll explore a series of user case scenarios that illustrate how the HEAC feature can simplify cabling requirements between digital home multimedia devices. The last portion of this paper discusses the architectural considerations and technical details involved with incorporating the Ethernet and Sony/Philips Digital Interconnect Format (S/PDIF) standards into the HDMI system-on-chips (SoCs) to support the HEAC feature.
HDMI’s global acceptance as the connectivity technology of choice for consumer electronics and PC multimedia products is largely due to its ability to deliver the highest quality audio/video signal over a single cable. Developed as a backwards-compatible enhancement of the Digital Visual Interface (DVI) standard, the HDMI electrical interface transports its data using three Transition Minimized Differential Signaling (TMDS) serial data channels which are logically interleaved to form a single serial data stream.
