Wan Yan vcd, once brilliant
Speaking of VCD, I believe everyone is familiar with it. VCD and DVD were very popular a few years ago, and they became the necessary protagonists of many home theater products. When VCD was just born, it was a great honor for anyone to own a 3-disc VCD player with karaoke function. Many people think that VCD, like karaoke, was invented by the Japanese, but it is not. The world's first VCD player is a fully domestic Wanyan VCD player. Wan Yan's name can be said to be a memorable milestone in the history of VCD in China and even in the world.
Before the invention of VCD, the concept of CD was unfamiliar to many people. Although there have been LD video players before, the popularity of LD players is very low after all. On the one hand, the price of discs is too high; On the other hand, resources are not abundant, which is one of the main reasons for the birth of VCD machines. As the first VCD research and development company in the world, Wanyan VCD has always been extremely mysterious to the outside world. Actually, Wan Yan is not as legendary as Jiang Wanmeng. He realized that MPEG technology is very advanced and invested hundreds of thousands of dollars 1992. After in-depth research, the world's first VCD player will be successfully trial-produced in September 1993. Compared with the traditional video recorder, the definition of VCD has been greatly improved, and it has a great price advantage over LD discs in terms of disc price.
As for the origin of Wanyan brand, there are actually some historical origins. Jiang Wanmeng cooperated with Chinese American Sun and invested170,000 USD. * * Registered Wanyan Company. Wan Yan's name is a Chinese combination between the two names. After the birth of Wanyan VCD, it aroused strong concern in the market, and many foreign enterprises also paid attention to it for a time. There are even some foreign companies willing to buy VCD from China and conduct research after returning home.
For Wan Yan, although the sales volume at that time was not much different from the market expectation, it did not pay enough attention to the support of property rights protection. Therefore, there is no core technology patent of VCD in Wan Yan. In Jiang Wanmeng's view, one of the main reasons for not applying for a patent at that time was to expand the market share as soon as possible and let more people be familiar with Wanyan VCD.
However, after a period of time, Wan Yan did not continue the glory of that year. Due to the high R&D cost in the early stage, Wan Yan gradually felt inadequate, and at the same time, the publicity effect of Wan Yan in marketing was not satisfactory. Therefore, Wanyan VCD gradually declined. In fact, in the VCD industry, not only in Wan Yan, many brands that have disappeared, such as Aiduo VCD endorsed by Jackie Chan, have also disappeared in the long river of history. Generally speaking, the decline of Wanyan VCD, on the one hand, is fierce market competition, on the other hand, it does not pay much attention to patented technology.
VCD maintenance
be shockproof
Although some brands of VCD machines have good shockproof performance, most VCD machines are not suitable for use in places with vibration, otherwise it will affect the laser scanning accuracy and seriously affect the sound and picture quality. Therefore, when using the VCD player, it is not advisable to move frequently, let alone collide and impact. Even when handling, handle it carefully to avoid affecting internal components.
be dust-proof
The accuracy of VCD machine parts is improved. If dust enters the machine, it will make its parts work abnormally and even cause serious failures such as damage. Therefore, VCD players should be placed in a clean environment, and corresponding dust-proof measures should be taken. Dust removal should be carried out by means of hair dryer cold blowing or vacuum cleaner suction when the machine is stopped. Don't disassemble the machine frequently for dust removal.
be cold-proof
In winter and spring when the temperature is low, if you put the VCD player in windward places such as doors and windows, it will inevitably be stimulated by the cold. This will make the VCD machine unable to work normally due to "cold", accelerate the aging of components, and thus lose its life.
Solar thermal protection
VCD player is afraid of both cold and heat. It is best to put it in a cool and ventilated place, not in direct sunlight, close to heat sources such as stoves and heaters. Don't put the VCD machine on the power amplifier and voltage stabilizer, and avoid putting it on carpets, sofas and mattresses, so as not to hinder the heat dissipation of the machine.
protection against the tide
When VCD is wet, it is easy to blur the optical lens, and the laser beam cannot pick up the signal normally. Dewdrops or fog will be generated in the machine when the climate is wet or the weather changes suddenly. If used, the VCD player should be powered on for a few minutes, and then played. Keep the machine dry at ordinary times, and turn it on frequently in wet weather such as rainy season to drive away moisture. If the VCD machine is often wet, over time, the parts will rust and even the whole machine will fail.
In the above article, we have introduced the development of Wanyan vcd in detail. Through the above, we can roughly understand the relevant information about the development of Wanyan vcd. Wan Yan vcd only existed on the historical stage for a period of time, and then withdrew from people's sight. It has a lot to do with itself. So few people know it now, except some professionals. The rapid development of science and technology has eliminated Wanyan vcd, a large part of which can only be attributed to itself.
