Show Me the Next-Generation HDMI

Short Description
With an install base of over 1.1 billion devices worldwide, HDMI has become the de facto multimedia interface for all digital home and mobile/portable multimedia devices. The recently introduced HDMI 1.4 specification further reinforces the HDMI message of performance, reliability and simplicity. Features like the HDMI Ethernet and Audio Return Channel (HEAC), introduced in version 1.4, further simplify digital home theater wiring while adding new and innovative features. In addition, the HDMI 1.4 specification supports advanced media capabilities such as enhanced color spaces for digital still cameras, 3D modes and ultra-high resolution display formats (up to 4x higher than 1080p) that will be key features in the nextgeneration of premium multimedia entertainment consumer electronic products.

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 Overview
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.

Digital Camera Technolohy Untangled

Short Description
Why megapixels are misleading and lenses still matter
1. Every technology has its limits
Digital Point-and-Shoot cameras are pushing the technological envelope so hard that some pundits are predicting the imminent demise of consumer-level Digital SLR cameras. Even $200 digicams (Digital Cameras) produce pictures that delight casual shooters, and fancier models are on offer all the way to $1,000, way past the prices of entry-level DSLRs. Finding your way around the digital camera market is harder than traversing the Scottish moors on a moonless night. This guide is an attempt to create order out of the current chaos.

The megapixel myth
The megapixel race reminds me of the ghetto blaster wars a couple of decades ago, when the makers of boom boxes tried to outdo each other with ever higher PMPO (Peak Music Power Output) ratings. PMPO is an artificial measurement that has little to do with the real world. Watts expressed in RMS are a better guide but still have little bearing on the quality of the music.
Much the same applies to megapixels in digital cameras, especially the point-andshoot digicams, and yet the race shows no sign of ending. Panasonic’s new Lumix DMC-FX150 and Canon’s Powershot G10 bridge camera go over 14 mp, and Nikon’s P6000 isn’t far behind. Others are joining this pointless competition daily.
Pixels are the tiny specs that make up digital images on a screen, but the term is also used to express the number of image sensor elements of digital cameras. More accurately, digital image sensors use electronic wells to collect photons (units of light). Larger sensors allow larger wells to be used that can capture more photons, improving the dynamic range in the eventual picture.
