As a next-generation digital video technology, Ultra-High-Definition (UHD) is gradually supplanting HD video across the consumer electronics (CE) landscape. In our homes, at work, and on the go, UHD is now available in a wide range of products, including televisions, computer monitors, video cameras, and mobile devices. Content producers, video service providers, hardware manufacturers, and retailers are all promoting the transition to UHD. For content producers and service providers, UHD presen
Embedded World is the largest computer and embedded systems exhibition in the world with 939 exhibitors from 38 countries and more than 25,000 visitors in attendance. This event spans all the latest embedded technology, including hardware (component, modules, and systems), software (OS, firmware, and apps), and associated services. A major focus this year is embedded security with a special show called “Safe for the Future” and an associated exhibition area dedicated to this topic. Both M2M an
Most smartphones include touch interfaces so that users can use simple gestures, like dragging, scrolling, sliding, or swiping to interact with their phone. Although touch technology is not new, some touch screens still perform poorly. In the ultra-competitive smartphone market, delivering a quality user experience is the key to success.
It is difficult to find information about smartphone audio input testing because the techniques are so uncommon and complicated. Since Allion has conducted audio testing for many years, we have accumulated a body of knowledge and practical experience in audio input testing, including testing of headphone input jacks and built-in microphones. In this article, we present our audio input test methods and some sample test results based on some recent test data.
Many people use smartphones to play music or record sounds. Due to the fast pace of technological change and fierce competition, consumers have high expectations of smartphone audio performance. Audio tests are usually subjective, but Allion applies objective laboratory methods to detect differences in smartphone audio quality.
You have probably heard the term the “Internet of Things”, or its abbreviation “IoT”, but what is it exactly? In recent years, high-tech experts have been declaring its imminent arrival and technology forecasters have been estimating its potential market value in the trillions of dollars. Despite all this, many people do not appreciate the importance of the IoT revolution. To bring greater clarity to this important issue, in this article, we address the following question: What direct impacts wi
Photo taking is a popular smartphone activity, as reflected in the rise of the selfie and apps like Instagram, and as a result, camera performance is important to users. As technology advances, camera module specifications steadily improve. At this point, image resolution and feature sets are comparable to those found in consumer-grade digital cameras.
SD memory cards are a compact storage medium for personal data and multimedia files (audio, images, and video). SD cards feature large storage capacity and fast data transmission speeds in a small form factor for use in a wide range of products. Driven by the trend for slimmer and lighter consumer electronics, the market for SD cards is growing fast. Typical applications include digital cameras, mobile phones, multimedia players, printers, computer systems, card readers, home entertainment equip
Seeing that the previous two rounds of audio quality testing failed to find any significant differences in performance based on capacitor type, Allion decided to investigate additional testing strategies. After some research, we found that some audio magazines mention a ‘whisper’ or ‘breathing’ sound, which inspired this third round of testing.
