1. To eliminate the problem of Caton, we should first start with our own device, files to the iPad, try to play them locally, use more players to test and eliminate the problems caused by machine software, and then start from the network. Try another route or network environment

2. Foreign brand, domestic Guangdong proction. The quality and quality are OK

but the price of this machine is higher than domestic. Only Blu ray program a in area C and all can be played; The content of area B cannot be viewed normally, and DVD can only play area 6 and the whole area. Network function is also very general, almost useless. However, you can escape from prison and watch videos online. You can imagine the absolute value after you escape from prison
the overall performance is better than that of Sony and Philips.

3. Avant garde's suggestion is to start from 320, and consider purchasing the American version on behalf of others. The price should be less than 1800.

Sony's new 370 looks good too. USB play is the highlight.
go 320, its audio and video quality and DVD double line effect are less than 400 US dollars, and LZ's tons of DVD is saved. Even if it's 120, it's not made by pioneer itself. OEM procts are not at the same level as pioneer's other machines
I'm more optimistic about avant-garde's machines. The 320 DVD line doubling effect now in use is amazing. Of course, I haven't compared it with other machines. I don't know how the line doubling effect of other machines is. As for Blu ray, I don't think the low-end machines of various brands will have any difference. As for the appearance, avant-garde's machines are relatively heavy, and Sony's machines are generally thin, Personally, I prefer heavy machines. In fact, I advise you not to worry about them. They are all low-end machines, so don't compare them so deeply. It depends on the shape. You can buy the one you like, and you won't regret it

8. There are several kinds of LED color and brightness testers that can be selected on ICT, one is foreign moles, such as smartfinn, lightprobe and FEASA, one is made by fixture manufacturers themselves, and the other is domestic professional moles, such as ICAT.

smartfinn is unstable e to its design defects. The analog output version of lightprobe is one of the popular ones, but its disadvantage is that the price is too high. FEASA's ICT version is frequency output, which is not convenient to use
some tools developed by some fixture manufacturers are unprofessional and lack of functions. Domestic professional LED color and brightness test mole ICAT is a good choice. It is highly professional, easy to use, cost-effective, and the output type is voltage output. It is easy to use in ICT
in short, lightprobe is a good choice if you don't care about the price. If you consider the cost performance, you can evaluate the performance of the ICT version of ICAT.

ICT is the prefix combination of information communications technology (ICT). It is a new concept and new technology field formed by the integration of information technology and communication technology

at the beginning of the 21st century, the group of eight in Okinawa issued the Okinawa Charter of the global information society, which holds that: & quot; Information and communication technology is one of the most powerful driving forces of social development in the 21st century, and will rapidly become an important driving force of world economic growth& quot;

As a matter of fact, ICT is not well understood in the information and communication instry. As a technology, it is generally understood that ICT can not only provide a variety of services based on broadband and high-speed communication network, but also is not only the transmission and sharing of information, but also a general intelligent tool. As for how much business there will be, this tool will & quot; Intelligence & quot; To what extent, the concept is still very vague. Triple play is just a foundation and prelude of ICT, and IPTV and mobile TV are just the tip of the iceberg

the similarities between CT and IT enterprises

both CT and it belong to the information instry with similar instrial characteristics. There are many overlapping nodes in the instrial chain, which complement each other and are inseparable. On the one hand, many IT manufacturers are also CT equipment suppliers, such as network switches and routers. On the other hand, CT itself is the main customer of IT service instry. For example, in 2004, in China's IT service market structure, the telecommunications instry accounted for 17.9%, second only to the financial instry (18.6%), ranking second

At the same time, in the process of informatization, the integration of it and CT is more and more close. Usually, a successful information application system must organically combine it and CT knowledge and resources, such as distance ecation, telemedicine, e-agriculture, e-government, e-commerce, information security and other fields
