If you want to know the global TV market trends in 2013, you can see from MediaTek's latest solution. Behind MediaTek is a large number of OEM / ODM customers of mobile phones and TV sets from Asia. The company may be the only company other than Samsung that has the right to decide how the development of mobile phone technology will dominate the new functions of the new generation of digital TV.
General Manager Xie Qingjiang of MediaTek was interviewed by EETImes US edition editor at the International Consumer Electronics Show (CES) in early January. The company ’s 8 popular technologies may be the major trends affecting consumer device design in 2013, including: (MulTI-screen), DIAL, 4Kx2K, HTML5, NFC, fast boot (fast boot TIme), quad-core / high-end GPU, and HEVC (H.265).
In the interview, Xie Qingjiang predicted that HEVC will become a key function in smartphones, tablet devices and TVs in a very short time; he also said that the newly emerging ultra-high resolution standard 4Kx2K is already: "Brand manufacturer customers Very important marketing tool. "
In addition, Xie Qingjiang believes that the so-called smart TV is still in the development stage, OEM / ODM manufacturers need to follow a variety of ways to achieve this goal, such as smart TV adapter (dongle), smart TV set-top box, Linux platform smart TV, and basic support for HTML 5.
Among many new technologies, MediaTek is particularly active in promoting the "multi-screen" display in the living room; the company claims to integrate Miracast certified Wi-Fi display technology with NFC to achieve MediaTek's latest four-core smartphone platform and smart The first manufacturer of seamless TV connection, it is possible to wirelessly stream high-definition video and multimedia content from a mobile phone or other mobile device to a large-screen TV with a single button, without the need to use the Internet Road access point.
The emerging open communication protocol DIAL, quietly developed by Netflix and YouTube, is also a trump card that MediaTek believes will achieve multi-screen usage scenarios. The term DIAL comes from "discovery and launch". It supports the secondary screen display function of a smartphone, can automatically find a primary display device (such as a smart TV) that supports DIAL in the same network, and place the application on the primary display As shown above, the user does not have to manually set or perform the device pairing process.
DIAL is a killer application to achieve "multi-screen"?
Xie Qingjiang regards DIAL as a "killer application" that realizes the multi-screen display situation in the living room. Compared with technologies that can map the content of a smartphone or tablet device to a large-screen TV display, DIAL claims to provide more functions, and its advantage is to fill the gap between the primary and secondary screens.
The official website of DIAL describes the differences in user experience that this technology can provide; when a user finds a video file through a mobile application and wants to play it on a connected TV, if DIAL is not supported, the following steps need to be performed :
1. Use the remote control to open the application menu on the TV;
2. Find a suitable TV application;
3. Open the TV application;
4. Search for the paired display device on the TV application;
5. Search and open the display device pairing on the mobile application;
6. Enter the 9-digit pin code on the mobile application;
7. Press the "Play with TV" button on the mobile app.
However, if the DIAL function is supported, only two steps are required:
1. Open the mobile application;
2. Press the "Play with TV" button on the mobile app.
In short, with DIAL, if you have a Netflix app on your phone, you can automatically connect to your TV at home and let the content on your phone play directly on the TV.
Will DIAL be a killer app?
The above DIAL is somewhat similar to Apple ’s AirPlay, which allows the content on the iOS platform to be seamlessly connected to the Apple TV set-top box and played on the TV, but only supports Apple ’s own devices. DIAL's goal is to enable all non-iOS platforms to seamlessly connect TVs, smartphones and other connected devices that support DIAL.
Faster boot speed and popular 4Kx2K resolution
Another new technology launched by MediaTek in 2013 is the fast boot function of the Android platform TV. According to the company ’s engineers, the current Android smart TV has a boot time of about 25 seconds, and MediaTek can now provide TV. Manufacturer customers' "cold boot" and "warm boot" solutions.
According to MediaTek, in cold boot mode, software optimization for Android code can be used to shorten the boot time to 12 seconds; at the same time, by the standby "suspend" mode established in DRAM, its warm boot The solution can greatly reduce the boot time to 2 seconds.
Although the market is skeptical about the development prospects of UHDTV (mainly because of the high price of this TV product and the availability of 4Kx2K content), Xie Qingjiang is more pragmatic on this technical issue the opinion of. He said that MediaTek sees the rise of UHDTV as a business opportunity to promote the company's SoC that supports 4Kx2K frame rate conversion; and the cooperation between Netflix and Samsung's UHDTV announced during CES also makes him think that 4Kx2K will happen soon.
Xie Qingjiang also believes that smart TVs using higher-performance CPUs / GPUs to execute more applications and better user interfaces will also quickly become the mainstream trend-this has been proven in the field of smartphones Development model. Although Xie Qingjiang mentioned in an interview that ARM's graphics processor core is getting better and better, MediaTek clearly continues to use ImaginaTIon's GPU technology.
Imagination announced in mid-January that it signed a licensing agreement with MediaTek for its PowerVR SGX Series5XT series of multi-core graphics processors. MediaTek said it will apply the technology to SoC components that target the digital TV market.
