Xue Juewu is a technical genius, Liu Xun pointed out the direction a little, Xue Juewu frowned and thought about using MPEG technology to implant images and sounds into a disc at the same time, and then create a new audio-visual product for home audio-visual.

Xue Juewu is not expensive is a technical genius famous in Columbia University, and she is involved in the research and development of MPEG technology, so it only took a while, and her frowning brows relaxed, "Little boy, this new type of audio-visual product you are talking about is technically feasible, and it is naturally no problem to concentrate images and sounds on a single disc, which is the best field for MPEG technology to be used." After making the disc, and then make a different from the disc player on the market to play this disc, this kind of disc player, theoretically feasible, technical, should not be too difficult. ”

Liu Xun pursed his lips secretly, and said secretly in his heart, you are not talking nonsense, I naturally know that VCD is theoretically feasible, and it is actually feasible, or I have nothing to do with running to Las Vegas to participate in this ghost Lao Tzu's exhibition, Lao Tzu is not an idle egg.

But then, Xue Juewu's next words attracted Liu Xun.

"It should not be difficult to develop this new type of CD, it will not take too long, but the manufacture of the DVD player may be more complicated, first of all, the laser head that can read the information from the disc, and the laser head is molded into a movement, which is probably the most complex structure in the new type of DVD player, but I am afraid it will take a while. The second is the decoding chip, to be able to decode the information compressed into the disc by MPEG technology, the decoding chip and then cooperate with other circuit control chips to make a decoder board, this is the second complex place, and then the system control chip, these three parts, is the ruthlessness of the DVD player. The rest, including the chassis and remote control machine, is very simple, and there is a special abrasive factory that can take care of it. ”

Liu Xun was overjoyed, Xue Juewu was worthy of the title of technical genius, it was not long ago, and he already had the overall solution of the DVD player in his mind, and the movement, decoder board and system control chip mentioned by it were the three core components of VCD.

Of course, these three core components are also a weapon for overseas manufacturers to make money from China in the future, and there is no technology in this area in China, let alone production capacity in this area. In the late nineties, the domestic VCD market was extremely hot, reaching sales of 60 million units two thousand years ago, but this huge VCD market, but most of the profits became in the pocket of overseas manufacturers such as Scoober, and this kind of huge profit should also have a share of Wanyan, but unfortunately, Jiang Wanmeng did not apply for a patent.

"Sister Wu, since it can be developed, do you agree with my idea?"

"Hmph, little brat, can't you see it, although you are not very proficient in technology, this brain is very bright, but, although theoretically it can be developed, and at most a year can see the results, but, do you think this new audio-visual product will have a future in the market?"

It's no wonder that Xue Juewu asked this question, although she is a technical genius, she also knows a little about business matters.

For technical products, many times the difficulty is not how to study it, for them researchers, there is a general direction of research, as long as it is not an impractical thing, it will always be studied. The key is not research and development, but how to transform the research results into products that are accepted by the market after research, and create real products and real wealth.

Otherwise, there are so many new technologies developed in Silicon Valley every year, and there are not many that can only be in the laboratory and cannot achieve market success.

Liu Xun smiled slightly, "Sister Wu, I have considered this issue before, and I even conducted market research in China. As he spoke, Liu Xun took out a stack of papers and handed it to Xue Juewu, but he didn't look at it, so he said a set of data that was too familiar to be cooked.

"Some time ago, I specifically investigated the domestic audio-visual market, according to my survey, in 1991, the sales volume of combined audio in the Chinese market was 1.42 million units, the sales volume of video recorders was more than 170 units, the LD DVD player was 1 million units, and the CD laser record player was more than 160 units, so we can roughly see how big the VCD market I am talking about."

“vcd？”

Liu Xun patted his head, and then he reacted, there is no VCD yet, this time and space, this is probably his own name, "VCD is the abbreviation of VideopactDisc, and it is the name I gave to this new type of DVD player, what do you think?" ”

Xue Juewu nodded, she naturally knew what videopactdisc meant, although she was a little puzzled about Liu Xun's naming, but she didn't pursue this question, "I didn't expect Xun Shao to put in so much effort, the data of the investigation is so clear, and it's all in my head, it doesn't seem to be a whim, right?" ”

Liu Xun smiled slightly, "I overheard people talking about the characteristics of MPEG technology when I was at Cisco before, and I paid attention to it, and then I came up with the idea of developing VCD, which was investigated in China, and this data was just obtained in the past few days." By the way, Sister Wu, you also know the price of the current popular VCR and laser DVD player on the market, right? ”

Xue Xuewu frowned, "I naturally know this, the price of laser discs is about four or five hundred, and the price of video tapes is not cheap, why do you ask this?" ”

The so-called laser disc is also known as LD laser disc, which is a popular image storage medium from the 1980s to the mid-1990s, mainly used to store movies, its size is similar to that of vinyl records, and the surface is similar to that of audio CDs.

LD laser disc players read the signals pre-recorded on the disc (similar to CDs) and convert them into video signals (e.g. PAL, NTSC) for television playback. It is characterized by its large size, with a diameter of 30 cm. LD discs were used to record video and audio in the early days, and later analog video and digital audio were used. Due to the large storage space of LD laser discs, there is no compression technology. Its storage method adopts double-sided storage, and there is also double-sided playback technology.

However, according to Liu Xun's memory from another time and space, because LD laser discs and playback equipment are not easy to carry and expensive, the price of a single LD laser disc is as high as hundreds of yuan, and the price of LD laser disc players is also as high as thousands of yuan. After the advent of VCD, LD went to bed. From the production of the first LD laser disc player in 1981 to the shooting of "Guillotine Valley" in 1999, it was the last film in the world to be released on LD laser discs.

Liu Xun smiled again, "Since Sister Wu is proficient in technology, she can naturally roughly estimate how much it will cost to manufacture such a disc if you use MPRG technology to concentrate images and sounds into a single disc?" ”

Xue Juewu frowned slightly, then pondered in his mind for a while, estimated a little, and then spoke, "If you don't consider the R&D cost and the copyright cost paid, the price of a VCD disc in your mouth should not be too expensive if it is between a few cents and two yuan, and as for the R&D cost, if the VCD disc alone, it should not be a lot, it should be within one million dollars." ”

Liu Xun nodded secretly, what Xue Juewu said, basically the price of VCD is indeed very low, but before it was developed, it was able to make such an accurate estimate, Xue Juewu deserved to be a genius in this field.

"Sister Wu, the price of laser discs on the market is now more than four or five hundred yuan a piece, and the price of video tapes is also very high, as for the VCD disc in theory, I also found someone to estimate it before this, and the conclusion is similar to what Sister Wu just said, the price is extremely low, even if the R&D costs and copyright fees are evenly apportioned, the price of a VCD disc is less than one-tenth of that of laser discs and videotapes, Sister Wu, do you understand what I mean?"

"Are you saying that the VCD you are talking about will be a home audio and video product that can completely replace the VCR and laser disc player on the market?"

The price difference between the two is so big, if Xue Juewu still doesn't understand what Liu Xun means, then she is a stupid hat, one of the directions of technology research and development is to reduce costs, and now this is not just a reduction, it is completely possible to replace it.

"That's right, Sister Dance, you think, the price of the laser disc player and the video recorder itself is very high, and the price of laser discs and video tapes is not low, although these two products are more popular in North America and Europe, but they are not popular in China, the reason is that the price is still the price, not only the price of the product itself, but also that the price of its film source is too high, even if you buy a machine, you need to spend a huge amount of money if you want to watch a movie, this is the opportunity of VCD, the price of VCD disc is more than ten times cheaper, only this one, It has become a huge advantage that can replace video recorders and laser disc players. ”

Liu Xun smiled and said this, looking at Xue Juewu's reaction, but what he didn't say was that although the above is the reason for the success of VCD, it is not the main reason, the main reason is actually VCD discs, piracy is quite easy, video tapes and laser discs, domestic manufacturers are difficult to pirate due to insufficient technology, but VCD is different, VCD technical requirements are very low, piracy is very easy, and profits are also very high, the reason why domestic VCD is so popular is because, since 95, In the southeast coastal area, a large number of low-priced pirated CDs began to flood the market, which made the sales of VCD begin to soar in 96 units, reaching 6 million units, and in 97 years it exceeded 10 million units, creating a sales miracle.
