PRODUCT HOW-TO: Dealing with the risks inherent in HDMI EDID testing
How to avoid the risks of traditional ad hoc random source and sink testing of HDMI's Extended Display Identification Data (EDID) protocol by going to a more systematic approach based on Audio Precision's APx analyzer to present metadata in a view like a logic analyzer.
DTV signal monitoring
Monitoring and measurement challenges in the digital television transition.
How to dim CFLs
Compact fluorescent lamps (CFLs) are replacing incandescent light bulbs at a rapid rate due to their tremendous energy savings and longer lifetime. Additional energy savings can be achieved by dimming, but the electronic ballast required to control the lamp has a higher cost and is difficult to design. This article explains how a CFL works, how to dim them, and describes a solution for 3-way dimming applications.
System testing of digital camera devices as reverse engineering
Modern digital cameras and cell phones containing digital cameras are merely complex microprocessor systems with ever-increasing amounts of functionality.
New transmission mechanisms for MOST enable powerful video applications
The MOST infotainment network was originally launched with a bandwidth of 25 Mbps, a bandwidth that was more than adequate for audio applications. The latest generation, MOST150, has a capacity of 150 Mbps, and is designed to serve powerful video and packet data applications in your car, as well as classic audio applications. Besides the higher bandwidth, MOST150 introduces additional transmission mechanisms such as isochronous data transfer over the synchronous network.
Build multicolor sign and video wall apps with RGB LEDs
Andreas Pohl describes the latest Avago RGB LED package approaches for full color indoor and outdoor displays and what needs to be taken into account when designing these large full color displays.
