40 TV recommendations:
In general, 40 inches is the starting size of Internet TV, and it is one of the most popular sizes currently enjoyed by consumers. The 40-inch Internet TV, in addition to meeting basic functions, is more of a product with a very high price-to-performance ratio. It is a product of the user's transition from traditional TV to Internet TV. Therefore, the author tends to have more Internet-based products, such as more content, more features, and better-designed TVs. Focus here on the next storm TV Super TV 40X this product, because the price is very competitive, great demand for purchase, before always need to make an appointment to buy, this TV is worth a look. The other two products are still pretty good, with basic hardware and features. Considering that there are a lot of sales, the product line is relatively stable, and quality should not be a problem.
At present, 43-45 TV is the main selling product of most manufacturers, and it is suitable for TVs used in small living rooms or bedrooms. In this size of television is very much, but also the major manufacturers push the product, most of the features and design are not much difference. But still find a few worthy of recommendation TV: Xiaomi's 43-inch TV, its hardware level is not high, because a lot of platform content, or worthy of recommendation; LeTV's Super TV X43S itself is a good product, but LeTV's exaggerated marketing is easy to cause bad impressions, and its products are not as bragging as good; Storm TV is a new product, the new 45-inch TV, more than the 43-inch standard size, 4K resolution in this size rarely , And the viewing experience is better, followed by the TV itself is a good hardware, the platform content is also very much, as the newly emerging dark horse brand, the price is very competitive, naturally worth recommending.
If you want to buy 50 TVs, consumers have the "pull-up" mentality. If you want to buy a good TV, you may not be very affluent, so you want to buy a very good TV. So I recommend TVs up to 3000. Philips anti-Blu-ray TV is also good, the old brand believes that there are many products used; Storm TV's VR TV 50X's exquisite appearance to meet the user has "forced" psychological, a lot of VR content is indeed worth a look In particular, there are children at home, to satisfy their curiosity, entertaining and entertaining is very strong; LeTV's TV is still a good popularity, this TV upgrade is still quite a lot.
Products above 55 inches are mainly used in the living room. In addition to being used for television, they will also serve as an accessory to increase the aesthetics of the living room. Generally, they will buy good-looking TVs and watch the TV industry. Therefore, some curved screen TVs, small fresh style TVs, and sophisticated appearance TVs are recommended. Storm TV's full range of products are rose gold, there are still many technical details in the palette, each of the rose gold is very natural and beautiful, their super body design allows you to change the motherboard, plug and play Easy to upgrade is also very convenient. Micro-whale TV is a small fresh style, sound quality is good; Hisense is a traditional old manufacturer, the product is naturally not bad.
For users who want to buy more than 60 TVs, the TV is equivalent to a screen. There are many other features that a TV box can handle. Therefore, it is more inclined to international brands. They do have advantages in screen effect and brand demand. . Therefore, the size of the giant is still dominated by Samsung, Sony, LG and other brands of television, domestic brands are also worth considering, after all, they still insist on supporting the idea of ​​domestic products.
Advantages of EPON:
EPON adopts a point-to-multipoint structure and passive optical fiber transmission mode to provide multiple services on Ethernet. EPON technology integrates low-cost, high-bandwidth Ethernet equipment and low-cost optical fiber network technology. Compared with other access technologies, it has unique advantages, which are mainly reflected in the following aspects.
Good compatibility: EPON uses Ethernet technology, which is by far the most successful and mature LAN technology, and it can be said to be the mainstream of user LAN technology. Because EPON is only based on the existing IEEE 802.3 protocol, and realizes the transmission of Ethernet frames in the user access network through minor modifications and additions, EPON is basically compatible with Ethernet technology. Using Ethernet as the access network has low cost and good versatility, avoids complicated transmission protocols and format conversion, high efficiency, and simple management.
Low construction and maintenance costs: The EPON system significantly reduces the number of optical fibers, optical transceiver modules, and central office equipment. As the cost of optoelectronic devices continues to decrease, EPON`s per-line equipment access cost is comparable to ADSL and CM, especially the current price of optical fiber is lower than that of cable. These conditions have become the basis for the development of FTTH. At the same time, the foundation of EPON is Ethernet, and related components and equipment of Ethernet are the lowest in price. Using EPON as the access network has low cost and good versatility, eliminating the need for IP data transmission protocol and format conversion. High efficiency and simple management. In addition, there are only passive optical components such as optical fiber and optical splitter between the central office (OLT) and the user (ONU). There is no need to rent a computer room, no power supply, and no active equipment maintenance personnel. Therefore, it can effectively save operation and maintenance. cost.
High bandwidth: EPON can currently provide a downlink transmission rate of 1. 25 Gb/s, a single-wavelength uplink rate of 125 Mb/s, and can be upgraded to 1 GB/s with the development of Ethernet technology. This is much higher than the current access methods, which can meet the bandwidth requirements of various services such as broadband Internet access, video on demand, online games, video phones, and digital high-definition televisions, and fully meet the bandwidth requirements of access network customers. And it can easily and flexibly allocate bandwidth dynamically according to changes in user requirements, which can be used as the user's ultimate access method.
