What is the difference between a set top box signal and a cable TV?

The former has advantages in terms of transmission quality, but the main advantage is not here. The set-top box signal is also a digital signal, which is convenient for the local radio and television department to manage, that is, they can identify you according to the authorization information in your machine; On the other hand, they can control what you watch the show.

The set-top box signal is the same as the previous cable TV transmission frequency40-870MHz, the previous carrier frequency is added with analog information, digital TV is added with digital information, and the transmission channel is the same.

Analog and digital, right? Traditional cable TV uses analog signals, and digital set-top boxes are responsible for converting digital signals into analog signals for TV.

What you are asking is the difference between the digital TV set-top box signal and the cable TV analog signal?

Can cable TV narrow its frequencies with current technology?

Reply to tracytimes: The difference between a digital TV set-top box signal and a cable TV (analog) signal is:

1.The input signal of the former is digitally compressed, and the latter is an analog television signal.

2.The signal output is different, the former is connected to the A V terminal of your TV in the form of A V (Audio**), while the latter is connected to the TV terminal of your TV in the form of RF.

Moreover, from a higher level, the difference between digital television and analog television is that, first, the number of channels has increased, and four or five hundred programs can be opened if conditions permit. Second, the picture is clearer and the sound quality is higher, and the audience can enjoy the standard definition TV program with ***** effect and CD audio effect on an ordinary TV set through a set-top box. Thirdly, digital TV is huge and rich in functions, and digital TV can provide many new services in addition to existing TV broadcasting programs.

The two most attractive points of digital TV programs are: first, specialization and objectification. Digital TV can open independent, professional, all-day channels, such as movies, cars, real estate, MTV, sports and other professional channels.

Also, the most important thing is: the money that comes out of your "pocket" is different, and the former is more!

Hello dear, happy to serve you, now start answering for you, typing may take a while, wait a while pro.

The TV signal source should be selected according to the HDMI interface accessed by the user. If it is judged that the user is connected to the HDMI 1 interface, it is necessary to select the HDMI 1 signal source on the TV, and if the access is HDMI 2 connection comic port, select the HDMI 2 signal source. There are several other situations to choose which TV signal source to choose - if the user is connected to a cable TV signal line, the signal source needs to be switched to TV mode.

I hope mine can be helpful to you, if you can, help click on the like in the lower right corner, I wish you a happy life, thank you very much

In the TV system interface,Select the type of signal state trace key source,It should be consistent with the Lianzhou cable carrying method (interface type),For example, ultra-clear digital signal cableHDMI1 or 2,Book Qiao A component (red, yellow and white terminals)etc。

Under normal circumstances, I think that the network TV set-top box, it should be to choose a faster one, this signal source will be better.

The choice of cable TV or network set-top box is the most tangled problem for current home broadband users.

If it is only for the first live TV, it is recommended to choose the cable TV of radio and television, which has the best live broadcast experience;

Well, let's compare the pros and cons between the two!

Reasons and disadvantages of choosing cable TV.

Cable TV is a more traditional way, which is relatively simple to use and more suitable for elderly users. Among them, cable TV live broadcast resources are relatively abundant. Compared with the network set-top box, the live broadcast is more real-time and the definition of the live broadcast picture is higher.

In particular, the recently launched 4K live broadcast can only be watched through cable TV, and the network set-top box cannot be realized.

The disadvantage of cable TV is that it is less flexible and can only be selected in the order of the program**. Broadband has become a necessity for every household, and compared with network set-top boxes, cable TV is less cost-effective and more expensive.

Reasons and disadvantages of choosing a network set-top box.

The network set-top box can be used as long as it can be connected to the Internet, and will not be limited by the scene and network. Compared with cable TV, the content resources are more abundant and have a higher degree of choice. It uses the Android system, which is more extensible and can also install other software applications.

Of course, the high cost performance is also a prominent advantage.

Due to policy reasons, the network set-top box cannot be broadcast live. Even by installing live streaming software, it is a pseudo live broadcast with a delay of more than 3 seconds. And subject to regional factors, it is impossible to realize the ** of local stations.

Speak for yourself by comparing the data.

The development of cable TV to network TV is one of the future trends, and the data has given us the answer.

The peak of cable TV occurred in 2015, and there has been a downward trend every year since then. At the beginning of 2016, it showed weakness and has begun to decline growth, and the annual downward curve is more obvious. The loss of cable TV subscribers is accepted by network TV.

The network TV set-top box can watch live broadcast like cable TV, but this is conditional, that is, this TV program must be connected to the Internet at the same time, generally CCTV and provincial TV stations are online, but prefecture-level TV stations may not be able to watch it. It also depends on the bandwidth and speed of the network.

Is an IPTV set-top box the same as cable TV? You can also watch the live broadcast, what are the advantages and disadvantages? Personally, I think that the advantages and disadvantages like this are that there are many network TV set-top boxes, and the choice is greater.

Network TV set-top box,Simply put, it integrates the hardware and software of online viewing。 It's the equivalent of a miniature computer console, so the viewing effect depends a lot on your internet speed.

Digital TV set-top box: It is a 'digital TV' set-top box.

IPTV set-top box: It is a 'IPTV' set-top box, it can be an 'analog' TV, or it may have a 'digital' program.

Which reception signal is good': the network and the running signal are good (comparable to non-wireless broadcast signals), stable, strong, so that can be well received.

The network TV set-top box receives a good signal, because as long as there is a network and the network is connected to the set-top box, you can receive the TV programs you need very well.
