Yamaha receiver and Energy RC-Micro review
The surround sound system reviewed was a Yamaha HTR-6260 7.2-channel digital home theater receiver with Energy Micro-RC 5.1 surround sound speakers. It was a decent system, given the price, but was not a system that met my expectations or made me feel like I had to call up my friends and have them come over so that I could brag about my purchase.
Deinterlacing with FPGA for HDTVs
Interlaced video is a succession of 50 or 60 fields per second, where each field carries only half of the rows that are displayed in each frame of video. This article explores different deinterlacing techniques and examines how FPGAs are increasingly being used for complex deinterlacing functions required for HDTVS.
Employ CEC in HDTVs to meet Energy Star 3.0
The popularity for the Consumer Electronics Control (CEC) function in home theatre systems helps the TV designer to meet Energy Star's 1W or less standby mode requirement. This article shows how you can meet this stringent requirement without sacrificing any display performance or features that consumers value.
Teardown: Inside Cisco's Flip UltraHD digital camcorder
The insides of the new Flip UltraHD, while leading edge, are not quite as interesting as the questions surrounding Cisco's acquisition of its developer, Pure Digital. Yet, the deal closed and the Flip continues to outsell all competitors, but maybe not for long.
Developing Multipoint Touch Screens and Panels With CPLDs
When a certain web-enabled multimedia smartphone hit the market in 2007, it transformed the way that consumers expect to interact with their handheld devices. Especially engaging is the fluid touch-screen interface that allows users to access an array of applications or scroll through web pages with their fingertips. To develop such sophisticated interfaces—without sacrificing time, budget, or power requirements—design with zero-power Altera MAX IIZ CPLDs.
Audio & Video Circuits for Single-SCART STBs
Almost all of today's European set-top boxes (STBs) have either single or dual SCART connectors. Those with a single connector can connect only to a TV, while those with dual connectors can connect to a TV and a VCR as well. Both include dedicated circuits between the MPEG decoder and SCART connector(s): for filtering and amplifying the audio and video, for generating the control signals, and (for dual scart products) switching audio, video, and control signals. This article discusses the design of discrete and integrated circuitry for single-scart STBs.
Using projected capacitive displays to create durable gesture-based touch screen interfaces
How projected capacitive technology can be applied to touch screens in embedded apps where the harshness of the environment might wreak havoc on older resistive touch screens.
PSRR: The Real Story about Closed- and Open-Loop Class-D Amplifiers
Understand why conventional power-supply rejection-ratio (PSRR) data for Class-D amplifiers is suspect, and examine an alternate way to look at the effects of supply ripple on audio-amplifier performance.
