In 1992, Sony launched the md format.

md, the full name is minidisk (mini disc), with a diameter of 6.4 cm. The diameter of ordinary CD disc is twelve cm.

The storage capacity of md is 160 megabytes, which means it can store nearly forty songs with good sound quality. It is twenty times higher than mp3.

And in terms of price, the md player is only about 300 US dollars, which is also cheaper than mp3.

Therefore, the current mp3 player is subject to technical and cost limitations, and it really doesn't have much use.

But summer is not too discouraged.

He knew that with the development of semiconductor technology, the capacity of flash memory will become larger and larger, and the price will become lower and lower.

For example, when he first went to college, the U disk was still a rare thing for students, and he needed to copy the files. The U disk was also very expensive at that time, and it cost 300 to 400 yuan for 64 m.

But a few years later, the price of U disk dropped sharply, and a G USB disk was only 100 yuan. The floppy disk was completely eliminated.

By 14 years, the capacity of an ordinary SD card was 16g, and the price was only 50 or 60 yuan. From 64m to 16g, it only took more than ten years, and it could double the average year.

So although the flash memory capacity is only eight m now, it may rise to thirty-two m and sixty-four m in one or two years, and the price will also fall very quickly.

So summer is still very confident about the future of mp3.

"Enjoy the patent application technology for MP3, and in addition, you can develop flash memory cards that use the USB interface to store and read data." Xia Tian advised.

Although mp3 is a mainstream music format, its patent rights do not belong to Tianxia Technology. However, in the field of mp3 players, Tianxia Technology still has many patented technologies.

For example, pressing the button to determine the previous song, displaying the song information on the LCD screen, using headphones to control the mp3 player, etc. These are all patented technologies created by Tianxia Technology.

In the future, if a company wants to follow the trend to produce mp3 players, unless it does not set these functions. Otherwise, as long as it is set, it must pay the patent fee to Tianxia Technology.

This is like the sliding unlocking of an Apple phone, which is a very practical human-computer interaction function. With a slight stroke of your finger, the screen is unlocked, which is so convenient. This unlocking method has also attracted many Android manufacturers to follow suit.

Apple immediately sued these Android mobile phone dealers in the name of patent infringement, and obtained hundreds of millions of dollars in claims and a large amount of patent licensing fees. It can be said that it was a big profit.

The USB drive can be regarded as an accessory for the development of MP3 players.

The mp3 player is connected to the computer through the USB interface, and the USB drive is also connected to the computer through this interface. The technology is understood.

The difference is that the mp3 player has added many functions such as audio decoding chips, power supplies, headphone jacks, LCD displays, etc. The USB flash drive is only used for data storage.

Therefore, the development of the MP3 player is successful, and the development of the USB drive is actually successful.

The anti-aging period of the U disk is much longer than that of the mp3 player.

The mp3 player is just a leisure and entertainment product. If it doesn't become popular for too long, it will be eliminated by more advanced technological inventions. Just like Apple's ipod, it will be eliminated by Apple's mobile phones in the end.

However, as an office supply, the U disk has a much longer life span. On the one hand, it is easy to use. It can be identified by plugging in, read and store very quickly; on the other hand, it is safe and reliable, and it is carried with you. As long as it is not lost, there will be no risk of data leakage.

In comparison, although many large-capacity mobile phones can be used temporarily as USB drives, they are much more complicated than USB drives.

Moreover, although there were many network disks on the Internet later, and the capacity was much larger than that of the U disk, it was not as safe as that of the U disk. Moreover, the transmission speed of the network disk was far less than that of the U disk.

Furthermore, the application range of U disk is also very wide. In addition to being used on computers, it can also be used in smart TVs, projectors, etc.

What's more special is that the U disk can also be made into a boot disk to install the system. This is something that other storage media cannot compare with. Therefore, the U disk has great development prospects.

If you win these two key patented technologies, then Tianxia Technology will make a fortune in the future.

In terms of world publishing, in addition to various entertainment magazines, the main focus is on publishing fantasy novels.

Nowadays, fantasy novels have been born for nearly ten years. After ten years of development, this type of novel has been criticized by the early days, and is now very popular and has developed in full swing.

In Hong Kong alone, there is more than one magazine called "Fantasy World". At the most, more than 30 magazines published fantasy novels. However, after competition and elimination, there are about twelve or three fantasy novels and magazines that are still being published.

Sales are also high and low. The most popular one is "Fantasy World" magazine, which currently maintains sales of around 40,000 copies per issue. For ordinary fantasy novels magazines, sales range from 5,000 to 10,000 copies.

According to Xia Tian’s creative fantasy novel, only "Panlong" is still serialized. This novel is also the guarantee that "Fantasy World" has always been a good sales.

Other novels are created by new Hong Kong writers. Although they are rising stars, their writing styles are very good, even better than summer.

However, because they are not as famous as summer, the sales of single-line books are far less than summer.

The so-called single-line book is a novel published in the magazine "Fantasy World". After reaching a certain number of words, it will be collected into a book and released separately. Just like the comics serialized in the magazine "Young Jump".

The single-books issued in the name of Xia Tian are far higher than those of other authors. Even in other places, the unscrupulous thief merchants will print the fantasy novels written by other authors on the name of Xia Tian for sale, which has really deceived many people.

...

However, in Xia Tian's opinion, the style of publishing in Tianxia is still a bit conservative, and always focuses on gossip news, fantasy novels, comics and other publications suitable for male entertainment.

But in fact, women's novels and comics are also very popular. In the past life, female novels were much more popular than male novels. Not only were they more subscribed, but they were also adapted into film and television dramas early on, which made many female writers make a fortune.

It is a mistake that Tianxia Publishing Company did not pay enough attention to female readers.

Moreover, in addition to entertainment-oriented books and magazines, books used for education are also very popular.

For example, tutoring books in primary and secondary schools, such as computer use teaching, cooking, fitness books, etc., were still very popular in previous lives.
