Even if the smart home industry is like a cloud, there are still no leaders, and most of them are playing ecological cards and establishing control centers. For example, the Homekit platform is added to iOS10, and the iPhone has become the control center. Unfortunately, even if it carries all of Apple's ambitions for the layout of the smart home ecosystem, there are few users. Although the smart home market is large, the user experience is often criticized by people. According to statistics, only about 10% of the Internet of Things products sold are activated and used all the time, and this also includes products such as smart bracelets, which are enough to show the crux of the current smart home. Even so, how can we do a smart home? Smart homes are not open enough and need to speed up the establishment and unification of standards In the smart home scenario, a series of smart items such as TVs, air conditioners, refrigerators, and robots are all placed on the Internet of Things. People can implement control on smart terminal hardware such as mobile phones and robots through voice and other methods. In theory, smart home can greatly improve the convenience of life. However, in actual operation, we have found many problems, such as the inability to interconnect due to the island state of the intelligent system among various home appliance companies. As we all know, the "not open principle" has become a major key factor that affects user experience and restricts the development of smart homes. Under this prerequisite, if the individual pieces of the smart home purchased by the user belong to different manufacturers, it may mean that he needs to download multiple APPs on his mobile phone to control all household items. Of course, many smart home manufacturers have also realized this problem and made efforts for it, such as Changhong and Haier. However, these are not enough. In order to better improve the user experience, more manufacturers are needed to join in and develop a uniformly recognized standard in the industry. Smart home needs "smart" to be human-centered "The essence of technology is to serve people instead of restricting them. In the past, many intelligences were false propositions. While increasing the price and cost of users, it also increased the time cost due to factors such as inability to use and frequent manual operations. Bringing convenience to users.†said Zhu Hongyun, manager of Changhong CHiQ-Life's innovative service design. From this passage, we can understand a fact of the current smart home: smart is not "smart". Because they are not smart, it is difficult for the elderly, children and other groups who are not familiar with smart operations to get started; because they are not smart, users need to operate the next instruction... In general, not being “smart†makes the user experience cumbersome, which is not Not convenient. In this regard, Broadlink CEO Liu Zongru said: "To open the market, it is necessary to solve the problem of intelligence. The development of artificial intelligence technology is the next dawn of the smart home market." Indeed, the addition of voice recognition technology saves people a part of the manual need, but it does not really reflect the value of smart home "smart". The "intelligence" of the smart home should take the initiative to start the service when the user needs it, instead of following the user's instructions step by step. For example, when the user says "I'm hot" and "Why is this hot", the AI ​​will associate with the equipment at home and make a comprehensive judgment: Maybe the air outside is very good, and it can be satisfied by opening the window. There is a demand; maybe the PM2.5 outside is very high today, then the air conditioner should be turned on to cool down, and then the air purifier should be turned on to optimize the indoor air quality. Therefore, this requires a real-time intercommunication of information between multiple sensors or technical modules. Taking the previous scenario as an example, after learning the user's needs through voice technology, the visual sensor, temperature sensor, etc. will also be activated to learn a variety of information. Based on this information, the smart home control system can make the above corresponding decisions. Concluding remarks It can be said that the current prospects for smart homes are still bright. However, because of the poor user experience, although many people will buy smart home products, the final result is nothing more than several: either consumers ignore this feature because they don’t use it, or consumers are feeling fresh in the past , Or it is not convenient enough and left aside. From this point of view, under the premise of poor user experience, the current situation of smart homes may not be as comforting as the statistics seem. At a certain level, the so-called market always seems to have some "nothingness" before it has grasped the users tightly.
Antenk DVI Series Digital Video Interface connectors are the standard digital interface for flat panels, video graphics cards, monitors and HDTV units. This series includes DVI-D (Digital), DVI-A (Analog) and DVI-I (Integrated Digital/Audio). Their unique crossing ground blades provide high speed performance at low cost. They are available in Straight or Right Angle PCB mount receptacles and mating male cable connectors. They support a data transfer rate of 4.95Gbps with a dielectric withstanding voltage of 500VAC. Each version features our specially designed contacts which improve signal performance and a zinc alloy shield that reduces electromagnetic interference (EMI).
Digital Visual Interface Cable Connectors
DVI ConnectorWith the advent of technologies such as DVD players, high-definition televisions, and even digital cable, the need for more advanced cables and connectors has increased. Digital Visual Interface (DVI) is one response to the growing need for interconnected systems, enabling digital systems to be connected to an array of displays. Yet DVI cables and connectors can also be complicated, and may lead to confusion between High Definition Multimedia Interface (HDMI) and DVI. Although the two systems have much in common, they service different niches of digital technology.
Digital Visual Interface
Older systems aren`t necessarily outdated systems. Although DVI preceded HDMI, it`s still widely used in both business and domestic settings. DVI connectors are designed to handle digital data transmission, incorporating three transmission channels in every connector link. The maximum bandwidth for data transfer is 165 megahertz, which is enough to relay up to 165 million pixels per second. Data is encoded for effective transfer, but a single link can handle around 4.95 gigabits per second of information. Double links can handle twice that amount.
Because a DVI cable carries information over a 165 megahertz bandwidth, complete digital resolution can be obtained. Using double link connectors increases the speed of transmission, but requires another cable. However, not many devices depend solely on a double link DVI, so this technolgy can be used on an as-desired basis.
Types of DVI Connectors
There are three general categories of DVI cable connectors: DVI-Digital (DVI-D), DVI-Integrated (DVI-I), and DVI-Analog (DVI-A). However, most connectors fall into one of the first two groups.
A standard DVI Connector is 37 mm wide and has 24 pins, 12 of which are used for a single link connection. When analog is involved, four additional pins are needed to support the additional lines of an analog signal. It is not possible to cross from a digital source to an analog display or vice versa. In those instances, an integrated connector is probably the best option. There are five common types of DVI connectors.
DVI-I Single Link
This kind of connector has three rows, each with six pins. There are two contacts. Because the connector is integrated, it can be used with both analog and digital applications.
DVI-I Dual Link
A DVI-I dual link connector can also be used with both digital and analog applications, but is configured with more pins to accommodate a dual connection. There are three rows with eight pins each, as well as two contacts.
DVI-D Single Link
Specifically designed for digital applications, a DVI-D single link connector has three rows of six pins, and looks much like a DVI-I single link connector. However, a DVI-D connector has no contacts.
DVI-D Dual Link
Also made specifically for digital applications, a DVI-D dual link features more pins (three rows of eight) for dual connections. Like a DVI-D single link, a DVI-D dual link connector has no contacts.
DVI-A
This particular type of connector can only be used for analog applications, and has three rows of pins. One row has five pins, one has four pins, and the last row has three pins. Like single link connectors, a DVI-A link connector has two contacts.
