With the rapid development of the IT industry, transfer quality, speed and application diversity have initiated a continued drive towards the development of faster transfer speeds. In order to enhance signal transfer encoding speed and shorten user waiting sessions. 1. Lowering package precision. 2. Providing full duplex transfer modes are both plausible ways to tackle the issue. In order to reach this goal, all individual components must be able to minimize signal decay, distortion and resistance towards interference.
Hence, the connector which acts as a bridge would also require an upgrade, due to the increasing role it plays in transmission quality and speed. The flow chart below shows the evolution of USB transmission speed from USB 1.0 to USB 3.1 Gen 2. Another important point to mention is the transmission mode which upgraded from half-duplex to full duplex.
Video Electronics Standard Association; VESA has released the DisplayPort High Bit Rate 3 ( or DisplayPort 1.4 ) early certification program in January 2017. Authorizing Allion to provide DisplayPort 1.4 Certification and testing service; as an ATL for VESA, Allion will introduce the specifications and details of DisplayPort 1.4 Certification and testing service.
DisplayPort 1.4 ( or in short DP 1.4 ) would be the latest specification presented from VESA, compared with DP1.2 the new DP1.4 incorporates the Display Stream Compression; DSC function. Hence, with a high compression rate of 3:1, it is able to support a higher resolution and refresh rate under the same bandwidth. Besides DSC, DP 1.4 includes Forward Error Correction, HDR meta transport in this new update. Therefore, allowing for better performance in video output.
On August 4th 2016, Allion Labs was officially recognized by MCPC ( Mobile Computing Promotion Consortium ) as the First and only ATL to provide mobile device MCPC Certification. ( Certification Details ) Actually efforts from Allion & MCPC have spent 2 years planning & organizing this important Certification program. Ever since the start of the program, Allion has worked closely with MCPC’s mobile device charging working group to set and plan the mobile device safety testing criteria and overall operation. We would also like to take this opportunity during the initial stages of the certification program to invite and interview some of the key promoters & facilitators of mobile device charging safety. Mr. Masahiro Hataguchi who is the Head Secretary & Chief of Internal Affairs for MCPC, also Chief Technical Commissar Mr. Kenji Oguma and finally CEO of Allion Labs ( Japan ) Mr. Hideaki Nakayama. Together they will share with us the facilitation & promotion of mobile device charging safety in the future.
As more and more of us rely on smart devices to lubricate and ease the perpetual motion of our daily activities, we may have alluded or taken for granted the safety and precautionary measures hence provided by industries and manufacturers.
Recent media coverage regarding the safety of consumer electronic devices, have caught our attention; especially when many of our gadgets today are manufactured and tested by the same institutions. Hence, possibly causing flaws or biased judgment during the certification process. Therefore, when another related incident from a product which, was born via this “α & Ω solution”. We as a responsible and professional institution had to ask ourselves the dodgy question we’ve all known for a while by now. “Is a one way arrangement from drawing board to certification and manufacturing, really what we want?” However, in defense of multinational conglomerates one must understand the implications and benefits of having everything wrapped up together as a single package. The following, will endeavor to shed light on these issues and possible alternatives that may further and promote better safety and scrutiny towards certification and compliance standards.
VESA has announced the up to date DisplayPort 1.4 standard, with promising support for 8K display and Alternate Mode on USB-C. In order to promote DisplayPort 1.4, VESA has hosted a series of workshops in Asia. Representatives from Allion attended the press conferences and workshops in Japan, Taiwan, and China. For this article, we share some important notes that are related to DisplayPort 1.4 standard and its certification.
