With the push of world famous manufacturers such as Apple, Google and Microsoft, the business opportunities of the new generation of USB Type-C have been fully exploded. In addition to using a single connector and cable to realize the USB charging and data transmission functions familiar to consumers, another major breakthrough of USB Type-C is the use of ALT Mode (alternative mode) which supports MHL or DisplayPort standards to enable USB interface to transmit UHD images, creating a new user experience. Can USB 3.1 Type-c Unify Interfaces? ]
Andre Bouwer, Vice President of Analogix Marketing, said that although HDMI had a slight advantage in the previous competition for video and audio transmission interfaces, in the face of 4K 8K ultra-high resolution competition, HDMI could only support 4K 60Hz due to its own technical constraints, and had no 8K blueprint. In addition, cost and other factors such as not included in the USB Type-C alternative mode specification, the future development was doomed.
Bouwer points out that as mobile devices are rapidly moving to USB Type-C connectors, USB Type-C will replace all UBS and HDMI cables in the future, and the company is very excited about the possibilities that DisplayPort will bring.
DisplayPort standard is formulated by VESA association without royalty. It was released in August 2014 in DP version 1.3. The DisplayPort alternative mode specification was released in September last year. It can support resolution of 4K 60Hz and above. It is expected that the standard of DP version 1.4, which can support 8K resolution, will be released by the end of this year.
Bouwer explained that the USB Type-C interface can support three alternative modes of video and audio transmission: DisplayPort, MHL and Thunderbolt. Thunderbolt is the combination of PCI Express data transmission and DisplayPort display technology, so it still belongs to DisplayPort in terms of video transmission.
As for the MHL interface, although the MHL3 standard supporting 4K images and the 8K superMHL standard have been published, Bouwer points out that the main problem of MHL alternative mode is that unlike DisplayPort, which can support charging, data and audio transmission with standard Type-C cable at the same time, it has to use special cable to perform image transmission or image+data transmission functions, and the manufacturer also has to branch it. Paying royalties will affect the wide application of MHL in USB Type-C.
In addition, another advantage of DisplayPort is that it uses electrical signaling technology similar to SuperSpeed USB, making it easier to integrate with mobile phones and tablet SoC. Therefore, Bouwer emphasizes that DisplayPort alternative mode will become the mainstream of USB Type-C audio and video transmission, and is also the only technology that can use standard full-featured USB Type-C cable to transmit 8K video.
Due to the excellent convenience for consumers and the significant reduction of electronic waste, the current USB interface will gradually be transferred to the USB Type-C standard. Now, the trend of USB Type-C has spread from notebooks, tablets and smartphones. By the end of 2016, USB Type-C TV will be on the market. It is expected that by 2017, the rear-seat screen using USB Type-C will also appear in the aftermarket. Bouwer expects to have 1 billion USB Type-C products worldwide by 2019, of which about 35% will support video output. [You don't know about the USB Type-C interface]
Deep plough DisplayPort market for a long time, and announced at the end of 2014 that DisplayPort chip shipments have exceeded 1 billion Analox is actively grasping this new wave of business opportunities. The company has released this year's C omputex USB Type-C chip ANX7428, which supports USB data, charging and DP alternative modes for laptops, and is now in mass production.
For smartphones, Analogix is currently a bimorph solution with SlimPort transmitter and USB Type-C chip, which can support UHD 30 Hz resolution. It is expected that ANX7688, a fully integrated monolithic solution, will be launched in the first half of 2016, not only to support UHD 60Hz, but also to reduce the BOM cost to $1, which will further promote the adoption of USB Type-C interface supporting DisplayPort alternative mode for mobile phones.
