Teach you how to buy a smart TV

First move: Don't be scared by multi-core processors

From single-core, dual-core to quad-core, cell phone manufacturers are keen to take the cell phone's internal processor to say how much work is going on. Looking at the current situation, color TV manufacturers are also unambiguous and more aggressive in their "nuclear battle."

In March, the reporter saw at the Shanghai Home Appliances Expo that the six-core was the highest configuration exhibited by the manufacturers at that time, and now domestic manufacturers have launched eight-core smart TVs. Here, it is necessary to remind that the concept of smart TV and mobile phone is not exactly the same thing. The dual-core and quad-core devices in mobile phones refer to two or four CPUs. The core of smart TVs not only includes the CPU, but also includes the GPU (graphics processor).

Such as "dual-core CPU + quad-core GPU", domestic manufacturers called it a six-core smart TV. But often referred to as "nuclear" refers to the CPU, seldom involves the GPU, so superimposed, it is the "invention" of the domestic color TV manufacturers, prices are often much higher.

The mainstream of the smart TV market is still dual-core (CPU). From an economical point of view, consumers can choose to run products with speeds of 1.2GHz or higher, and they can basically guarantee the operation of large-scale software.

The second measure: memory to figure out GB and Gb

In the last issue of this report, many users had purchased a smart TV with too little memory, which caused the machine to be stuck and restarted during the operation. This was irritating because the users were all instructed by the stores. The staff "deceived".

Here first universal knowledge: memory units are commonly Byte and bit two, 1Byte=8bit, that is to say 1GByte (1GB) = 8Gbit (8Gb), we usually call 1G memory refers to 1GB, rather than 1Gb .

In the computer PC industry, the Byte unit is generally used for description, and the smart TV uses the bit as the label unit. This is also the current practice of major television manufacturers in China. However, the reporter visited the store and found that when shopping guides introduced products to consumers, they all said that there was a lot of G in memory, and they all covered up the fact that Gb was only one-eighth the size of GB.

For example, a smart TV, shopping guide staff said its memory is 4.2G, while the reporter saw in the system configuration of its products is 4.2Gb, conversion, the actual memory size of this TV is only 537MB.

In general, the smart TV's memory should be more than 1GB in order to ensure smooth operation of large applications.

The third measure: select Andriod4.0 above <br> <br> system in the smart phone, Andriod dominate in the field of intelligent television, Andriod is dominant, the most widely used.

Now when everyone buys a smart TV, we must pay attention to whether the operating system is Android 4.0, or Android 4.2. The Andriod system has been released in multiple versions, but the previous version does not apply to smart TVs, such as 2.3 and previous versions developed specifically for mobile phones, 3.0 version is only suitable for tablet computers. Until the 4.0 version came out, it was applied to smart TVs. Some TV manufacturers have already launched smart TVs equipped with Android 4.2.

However, a small number of smart TVs on the market are still using Andriod 2.3 version, which is suitable for the operating system of small screens on mobile phones. It is simply on the 40-inch screen, and the experience will certainly not be good. In addition, domestic manufacturers have also launched their own research and development of smart TV operating platform, but did not cause major repercussions in the market, consumers should avoid these products when purchasing.

Simply speaking, if you choose a smart TV, you need to choose products with an operating system of Andriod 4.0 or later. If the operating system information is not visible in the product configuration, or if the product is not clearly described by the shopping guide, it is not the most appropriate purchase.
