LEDs Will Change the Capabilities of Projectors.  .  .  p. 51
A string of new projectors are being developed with light-emitting diodes (LEDs) as their light source. Replacing conventional high-pressure mercury lamps with LEDs makes it possible to create a battery-operated front projection system that can fit in the palm of your hand; or a rear-projection system with a 100 percent color gamut.

With One More Step, AV Devices Will Implement DRM Using an Unique ID Tied to the Processor.  .  .  p. 61
Semiconductor manufacturers providing microprocessors for audio-visual and portable equipment have begun allocating space within each processor’s LSI circuit for storing individual IDs. Having a device carry its own unique ID will help strengthen areas such as digital rights management (DRM) in preparation for the diversification of content distribution.

The Google You Don’t Know.  .  .  p. 83
If you see Google as a company that just creates search engines for PCs, you may soon regret thinking that. Google, whose own employees are even staggered by the speed with which the company has grown, is expanding its influence to cover almost everything from digital home appliances to large-scale computers.

Proposing a New Evaluation Method for Electromagnetic Noise Aimed at Preventing EMC in Wireless Devices.  .  .  p. 115
With portable devices taking on a variety of wireless functions, such as mobile phone, wireless LAN and digital television reception capabilities, attention is focusing on the phenomenon called “self-interference.” Faint electromagnetic noise from inside devices is said to impair wireless receiver sensitivity, and the extent of the problem has the potential to escalate further as devices become smaller and multi-functional.
Taiyo Yuden Co., Ltd. has developed a method for measuring amplitude probability distribution (APD), allowing a quantitative evaluation of the faint electromagnetic noise at the root of the problem. The company has actually confirmed that the method can identify the level of electromagnetic noise at which the bit error rate of mobile phones deteriorates.
Credible evidence has been acquired that will make this measurement method an effective way to gather the information necessary for electromagnetic compatibility (EMC) measures relating to self-interference. Countermeasures had previously been formed through trial and error, but now it will be possible to take more strategic action.

IrDA Modules.  .  .  p. 124
Infrared Data Association (IrDA) specifications for short-range communication using infrared light continue to evolve. A modified set of specifications, called “IrSimple,” has been formulated for the communications protocol due to the trend of reviewing easy operation and a rising demand for high-speed data communication via mobile phones.
To take full advantage, the spotlight is likely to be directed at components compatible with the fast infrared(FIR) specifications for high-speed transmission. Of serial infrared (SIR) compatible products, the dominant type at present, products with television remote control functions are rapidly increasing. In both domains, shipments of transceiver modules, a key component, are soaring and prices continue to plunge. Module sizes, too, are becoming ever more compact.
The main reason for this is their being incorporated into mobile phones, which face tough size restrictions and are shipped out in their thousands. The initial standards emerged more than 10 years ago and are still being improved upon.

Validation Method for Embedded Software (Part 4).  .  .  p. 132
This installment describes how to master the “Garakabu” model test tool jointly developed by CATS Co., Ltd, Fukuoka Laboratory for Emerging and Enabling Technology of SoC (FLEETS), and Kyushu University. Properties that can be validated are explained using the sensor switch and car stereo examples introduced in the previous installment.

Mobile One to Many Communication: Push-To-Talk.  .  .  p. 140
In November 2005, NTT DoCoMo, Inc. and KDDI Corp. set up new “push-to-talk” (PTT) services enabling one-to-many communication. PTT services use different technology to conventional telephone services. The key points will be described here in three parts.
