Home gateways have recently become a hot Topic

Home gateways have recently become a hot topic. For ordinary users, the home gateway can be simply understood as a home wireless router. Of course, home gateways can do much more than the range of home wireless routers.

Chen Comin, Broadcom Company Broadband Communications Division of Technical Vice President and Bo Tong Company academician, in the current fiery "smart home" concept of Sohu it said that the family gateway as a basic service unit, is a variety of services to the portal, it will be more and more important in the future role of intelligent family.

As the upstream chip manufacturer, Chen Comin said, Bo Tong has a relatively complete intelligent home solutions. The Intelligent gateway plays the role of the link between cloud service and home intelligent device.

Smart home needs "open source"

After several years of development, the current telecommunications operators and broadcasters have been from the "interconnected family" to the "smart family" change. In this transformation process, the family Gateway also has a variety of access methods, such as DSL, GPON, EPON, CABLE modem and so on, and within the family there are WiFi, Powerlan, WLAN, LAN, MOCA and many other networking methods. The adaptation and integration of various connection modes are now available.

In the intelligent home, the service is more diverse, in addition to video and equipment, such as wireless control, video content, service distribution has become the basic function of Home intelligent Gateway. In addition, because the application of smart home is very diverse, many intelligent control applications can not be set in advance, in order to ensure the user experience, "open source" has become a very important part of smart home.

According to Sohu it understands that domestic manufacturers basically do not have the so-called "open source" spirit. In the various manufacturers have entered the field of intelligent home, for their own interests, the different brands of smart home equipment due to different protocols, often not interconnected, seriously affecting the user experience.

In such cases, the home intelligent Gateway needs to have a very high flexibility, in addition to adapting to a variety of access methods, open source software has sufficient management capabilities, but also to adapt to the diversity of home devices wireless connection.

4K Super Clear can not only look at "resolution"

Data show that in the home, about 80% of the user application is to watch the video. In view of the current industry generally stressed that TV and content using "4K resolution" problem, Chen Comin to Sohu it said that 4K technology is not simply a resolution of the upgrade, but also the promotion of color domain space.

In most cases, high-definition 1080-resolution TV has been able to meet the needs of most home users, 4K TV, if only the pursuit of "Resolution", the user's attraction is clearly not enough. The 4K video standard uses the ITU R BT 2020 (REC 2020) gamut standard, which is relative to the BT 709 (REC709) standard used in HD, the gamut space is about 70%. And in the color depth aspect, also from 709 uses 8bit to ascend to 10bit. 4K has a significant improvement in color levels and transitions.

Of course, the promotion of Intelligent Home Gateway and service, in the domestic subject to the action of cable operators. Because of OTT in such as high-definition, online real-time programs, there are still unsatisfactory place. Although many internet companies already have similar "smart router" products that can provide audio-visual sharing and home control, there is a long way to go in the ideal of multiple-screen integration, super-clear experience and intelligent home control.
