The difference between TV set-top box and cable TV set-top box

1, the smart TV box can not only watch live TV, but also watch various on-demand programs. It also supports adding program sources and watching a large number of overseas channels.

2. The cable TV set-top box plays the content by receiving the cable TV signal, and the smart TV box receives the network signal to transmit data.

In addition to the machine fee, the cable TV set-top box also needs to pay a certain content service fee every year. As long as the smart TV box pays the box fee, it needs to pay the network service fee separately;

4. The program source (480P) of CATV set-top box is clear and stable, but the resolution is not high; Smart TV box has high resolution, but the program playback is not very stable;

5. Cable TV set-top boxes need to be customized to watch high-definition (720P) programs, and high-definition content service fees need to be charged again. Smart boxes can watch not only high-definition programs (720P), but also full-definition (1080P) and ultra-high-definition (2 160P) programs, most of which are free of charge. However, under the control of the general administration, the contents of the smart box.

Shopping tips:

1, film source

Everyone has higher and higher requirements for the clarity of TV. Many TVs also provide HDMI high-definition interface, and many box products can also meet this demand in hardware. However, different manufacturers and TV source cooperation institutions are different, and the high-definition storage and technology are very different. Some manufacturers can provide HDTV viewing experience, but there are few sources to watch, which you should pay attention to when purchasing.

2. Hardware configuration

Hardware configuration is also an important indicator, just like the computer we buy a mobile phone. The number of CPU cores is gradually upgraded from single core, dual core to quad core, and the memory capacity is gradually increased from 256 to 1G to 2G. In theory, of course, the higher the order of magnitude, the better, because it can keep up with the development speed, the machine will not be eliminated, but it is also necessary to consider the cost performance, do not blindly pursue high configuration, just enough.

3. Operating system

At present, most of the boxes available in China are Android, which is also a relatively powerful and universal operating system. Many manufacturers optimize their UI according to the Android system, so we should pay attention to the optimization of their UI by different manufacturers, whether the operation is convenient, whether the system runs smoothly and so on.

4. Extended functions

Although the most important function in buying an Android set-top box is its ability to play high-definition content.

But in addition, some extended functions provided by the set-top box, such as whether the set-top box supports hard disk playback, whether it supports LAN function, whether it can browse pictures, browse websites and so on. It is also a factor that we should consider when purchasing. A good Android set-top box can not only watch high-definition video on the Internet, but also satisfy more network applications.

5. Firmware upgrade capability

The hardware technology of high-definition network set-top box is very mature, but the software still has room for further improvement, especially the strong compatibility and expansibility of network set-top box, which can be realized by firmware upgrade. Therefore, when choosing, you need to consider the ability of firmware upgrade, and the product you bought at that time does not support a certain function, which can be solved by firmware upgrade, and some product failures can also be solved by firmware upgrade.

6. After-sales service

As a new product, under the pressure of market competition, the development of chips, software and hardware is extremely fast, and problems are inevitable, so after-sales service is extremely important. How to make up for the congenital deficiency of products through after-sales service, improve customer satisfaction, reputation and brand loyalty, and then establish product reputation and enhance brand value is a problem that every player manufacturer should seriously consider.
