The use of the telnet command on the Windows 10 operating system can be roughly divided into two parts:
Part 1: Configure telnet
Part 2: Entering the Black Window
Finally, let's debug and try connecting to the server.
Part 1:
Firstly, configure telnet through the control panel
Open: Control Panel - Programs - Start or Close Windows Functions - Check Telnet Client
Part 2:
Keyboard key operation: window+r - enter cmd enter - enter the original black window - enter telnet enter - enter quit to exit telnet mode
Debugging section:
Thinking organization:
1. The telnet on the window side has been opened
2. The ping command check shows that the network condition is unobstructed
3. And there's something I don't know about

In the words of an industry insider, the spelling of 'telephone' for companies here in the future should be 'television'. This indicates a trend: future telephone companies are transitioning towards television. So, what is the actual development of IPTV?
IPTV has become a fashionable term nowadays, at least in the telecommunications industry, it has become a word that is almost used every day and is increasingly being discussed by people. At the Telecom NEXT conference held in the United States in late March, most of the presentation was about how phone companies deliver video programs. In the words of an industry insider, the spelling of 'telephone' for companies here in the future should be 'television'. This indicates a trend: future telephone companies are transitioning towards television. So, what is the actual development of IPTV?
Firstly, consumers do not know what IPTV is.
A recent survey shows that nearly half of American and European consumers do not know what IPTV is. According to a survey of 6000 users in the United States and Europe (including Spain, the United Kingdom, Italy, France, and Germany) conducted by Accenture, a leading management consulting firm, 46% of users are unclear about what these letters IPTV refer to. In Italy, even 4% of respondents believe that IPTV is a new television competition program.
People in the telecommunications industry are enthusiastic about using technical terminology in their marketing, but the survey results above indicate that this approach is not suitable for IPTV. What telecom companies should do is focus on selling the concept of IPTV: it can enhance the experience of ordinary viewers watching TV, and it is expected to provide more advanced interactive services in the future, which requires a process of market cultivation.
Secondly, there is no mature charging model yet.
Price is a major obstacle to IPTV. In the survey conducted by Accenture, 54% of respondents stated that they are unwilling to pay additional fees for an entertainment service that allows them to search for TV, radio, and music programs at any time.
The IPTV revenue and expenditure model is based on many assumptions, but these assumptions assume a well known and stable market, while at the same time, the core definition of IPTV is in flux.
The behavior and traffic patterns of users will guide the development of the industry. The most important part is to distinguish between online traffic and offline traffic. The biggest concern of network owners is that they only provide a network that others can use for free without receiving any benefits from traffic. So, they must distinguish between online services and offline services. Layered services will protect the interests of both network owners and users.
Once again, telephone companies still face legal obstacles in terms of television services.
In the United States, wired services need to be provided under the policy supervision of county and city governments. For telephone companies, negotiating with the government at the local level is time-consuming. Verizon once mentioned that even if it receives a local license one day, it still takes several years to provide video services to all its users.
The new laws in Texas and Indiana allow telephone companies to obtain licenses from the state government without the need for local authorization, thus greatly simplifying the already lengthy process. Virginia has passed a similar law, but it has not yet taken effect. Currently, IPTV is actually guided by smaller companies, many of which serve rural areas. In addition to obtaining some concessions, their systems are smaller, making it easier for them to adopt new technologies. For large telephone companies, the franchise war is harsh, as they have to deal with thousands of local governments.
Finally, the biggest challenge is that the entire IPTV industry may underestimate what it should do to deliver services, as user experience rather than technology is the most critical factor for IPTV. Although IPTV has some technical advantages, it remains to be proven whether these advantages can win and retain users. Meanwhile, some analysts believe that IPTV does not really need a technological advantage to compete with cable companies. For consumers, convenience is a temptation. Being able to obtain wired telephone services, wireless telephone services, broadband internet services, and television services from a company, also known as "quadruple playback," has great appeal to consumers. The survey shows that users have a clear interest in the types of services that IPTV can provide. For example, in the United States, 37% of respondents choose to be able to watch programs anytime when it comes to how to better watch TV. Moreover, 30% of respondents in Europe stated that they need more movie channels, which IPTV can provide technically.
However, from the above content, it can also be seen that many IPTV implementations are involved in old paradigms such as telephone services, television, video on demand, and so on. After all, IPTV is only an improvement, not a true innovation. When the market changes and remains stuck in the old paradigm, perhaps one day, operators will have to significantly lower prices to retain users. Therefore, in order to win in long-term competition, telephone companies should make certain changes in direction and develop more other service content. Moreover, it should be a revolutionary business with true innovation and an order of magnitude of improvement. And this is something that IPTV operators have not truly solved.

Docker for Windows is a Docker Community Edition (CE) application. The Docker for Windows installation package includes everything necessary to run Docker on a Windows system. This topic introduces pre installation considerations and how to download and install Docker for Windows.
What to know before installation
If your system does not meet the requirements for running Docker for Windows, you can install the Docker Toolbox, which uses Oracle Virtual Box instead of Hyper-V.
Docker Toolbox and Docker Machine users must read: Docker for Windows requires running Microsoft Hyper-V. If necessary, the Docker for Windows installation program will enable Hyper-V for you and restart your computer. After enabling Hyper-V, VirtualBox will no longer function, but any VirtualBox VM images will be preserved. The VirtualBox VM created using docker machine (including the default virtual machine typically created during toolbox installation) will no longer start. These virtual machines cannot be used in parallel with Docker for Windows. However, you can still use docker machine to manage remote VMs.
Virtualization must be enabled. Typically, virtualization is enabled by default. (Please note that this is different from enabling Hyper-V.).
The current version of Docker for Windows runs on 64 bit Windows 10 Pro, Enterprise and Education (1607 Anniversary Edition, Build 14393 or higher). In the future, we will support more versions of Windows 10.
Containers and images created using Docker for Windows are shared among all user accounts on the installed machine. This is because all Windows accounts will use the same virtual machine to build and run the container. In the future, Docker for Windows will better isolate user content.
Nested virtualization scenarios, such as running Docker for Windows on VMWare or Parallels instances, may work, but cannot be guaranteed (i.e. not officially supported).
Docker for Windows installation includes: providing Docker Engine, Docker CLI client, Docker Composite, Docker Machine, and Kitematic.
Installing Docker for Windows
1. Double click Docker for Windows Installer.exe to run the installation program.
If you have not yet downloaded the installation program (Docker for Windows Installer. exe), you can obtain it from download.docker.com..
2. Follow the installation wizard to accept the license, authorize the installation program, and then continue with the installation.
You will be required to use the system password to authorize Docker.app during the installation process. Requires privileged access to install network components, link to Docker applications, and manage Hyper-V virtual machines.
3. Click Finish on the installation completion dialog box to launch Docker.
Starting Docker for Windows
Docker cannot start automatically. To click Start, search for Docker, select the application in the search results, and then click it (or press Return).
When the whale in the status bar remains stable, Docker can run normally and be accessed from any terminal window.
If the whale is hidden in the Notification area, click the up arrow on the taskbar to display.
If you have just installed the application, you can also receive a pop-up success message, provide subsequent steps, and provide a link to this document.
After initialization, select 'About Docker' from the notification area icon to verify if you have the latest version.
congratulations! You are running Docker for Windows.

Definition of IPTV
What is IPTV? This is a fundamental issue.
Before the introduction of the definition of IPTV by the International Telecommunication Union, different standardization organizations and related enterprises had various interpretations of IPTV, and in China, IPTV was also translated into various forms - interactive television, online television, interactive television
At the same time, different industries, operators, and equipment manufacturers have different opinions on what IPTV can do. Although the prospects of IPTV have been described as a huge cake, how to slice the cake has become the focus of industry attention, and all parties are doing their best to seize the opportunity in this huge market.
In fact, due to unclear policies leading to unclear industrial models, behind the popularity of China's IPTV industry, more people are cautiously watching; The limitations of bandwidth and content, as well as the barriers to unified terminal standards, have led to the inability to promote IPTV on a large scale, many experiences cannot be summarized, manufacturers are at a loss, and marketing has also fallen into the awkward situation of thunder, rain, and little. Therefore, the introduction of IPTV international standards will to some extent change the awkward situation of unclear identity, uncertain standards, and feudal separatism.
In the IPTV standards published by the International Telecommunication Union, the definition of IPTV is as follows:
IPTV is a multimedia service, such as television, video, audio, text, images, data, etc., and has certain QoS/QoE, security IPTV is defined as multimedia services such as television/video/audio/text/graphics/data delivered over IP based networks managed to support the required level of QoS/QoE, security, interactivity, and reliability.
From the definition of IPTV by the International Telecommunication Union, we can see that it mainly includes the following meanings:
IPTV is a multimedia service, and services such as television, video, audio, text, image, and data are all manifestations of IPTV;
IPTV is carried on a manageable IP network and has corresponding level requirements for security, reliability, interactivity, and service quality.
IPTV is not so much a business as a service. Although it may seem like a different translation of a word, it means looking at IPTV from different perspectives, and "business" is more from within the operator, which is the business project used by the operator to earn profits; However, "service" is defined from the perspective of customers, that is, IPTV can meet the needs of different categories of customers. Therefore, the author prefers to interpret IPTV as a service to customers rather than an internal business of the operator.
Through this definition, we can find that concepts such as online television and interactive television are only a description of IPTV's image and cannot fully cover the meaning of IPTV. However, this definition still has certain positive significance for promoting IPTV and promoting its development in China.
IPTV service requirements
In the IPTV standard, the service requirements of IPTV are subdivided and listed according to service direction, function, etc. Some are required, some are recommended, and some are optional. This is actually a law that has been explored based on summarizing the development experience of IPTV around the world.
In the early stages of IPTV development, people wanted to incorporate all the functions that the Internet could provide, not only to achieve video on demand, video live streaming, online browsing, but also to achieve applications such as videophone or conference television, pursuing "large and comprehensive". However, this is not realistic, as the result often makes the devices and systems too complex and the network overwhelmed. Therefore, it is not only necessary but also necessary to classify IPTV services appropriately.
In short, IPTV is a new industry formed by the intersection of multiple traditional industries, including operators, equipment manufacturers, content providers, terminal manufacturers, and other links. The coordination and integration of the industry chain is the determining factor for its market success; The value chain of IPTV is more complex, involving multiple types of enterprises such as set-top boxes, CDNs, DRMs, middleware, audio and video codecs, etc. The complexity of the IPTV system and architecture can be seen from its standard documentation.

According to the pay TV forecast update report from the analysis company Digital TV Research, the number of IPTV users will surpass that of cable TV by 2026. Between 2021 and 2026, IPTV will increase by 63 million users, bringing the total number to 398 million.
The main reason for this situation is that the huge shift from cable television to IPTV in China will continue, "explained Simon Murray, chief analyst of digital television research.
By 2026, China will have 226 million IPTV users, while the rest of the world only has 172 million left. Between 2021 and 2026, China will add 19 million IPTV users. However, by the end of 2026 during the same period, China will lose 39 million cable TV users, bringing the total number to 89 million.
Digital TV Research predicts that between 2021 and 2026, pay TV users will increase by 13 million, bringing the global total to 1.01 billion. China will continue to provide nearly one-third of the world's pay TV users, expected to reach 315 million by the end of 2026. India will account for 178 million. By 2026, China and India will jointly account for half of the global pay TV users.
