At present, MP3 has entered a period of rapid growth and is slowly moving into a period of maturity, and the market has been formed on a large scale.
MP4 is in the market introduction period. Since ARCHOS released the first MP4 portable theater in 2002, many companies are optimistic about the development trend of MP4. The development momentum has become the latest growth point of mobile digital technology, and its development potential is even greater. than that of MP3 In about 3-5 years, it will form a huge market of nearly 10 billion in China. MP3 and MP4 will coexist and develop together for a long time. Ever since Sony invented the Walkman in 1978, portable music has reached people. Until 2004, the Walkman went through the Walkman-type tape, CD, and MD process. Today, it has become a digital MP3 Walkman, and Walkman music has become more portable and fashionable. In fact, as far as MP3 is concerned, with the further improvement of sound quality, the sound quality has approached CD quality, and the “listen” function of the Walkman has reached its peak. Many manufacturers began to consider the needs of consumers from other aspects, so a large number of multifunctional MP3 players began to appear on the market, and the Gmini400 of the French company ARCHOS even appeared in the MP3 player that can watch movies and play games. games. . So, in terms of technology development and trends, the integration of multifunction will be the final direction of MP3. However, although the growth of the MP3 market is amazing, MP3 can only be limited to the world of “listening”. To meet people’s need to “watch” with other people, ARCHOS, a famous French mobile digital manufacturer, proposed the concept of MP4 portable theater in 2002. And launched the world’s first MP 4 player, MP4 sounds very similar to MP3 in name, however, the functions between the two are very different.

And MP4 is different. You can listen and watch, and it has rich entertainment functions. It is an entertainment novice in the digital age, and it is a big step forward than MP3. At present, most of the international manufacturers consider MP4 as their flagship product and add many popular features to MP4. Among them are complete portable theaters like the ARCHOS AV400. AV400 is based on video playback, audio playback, video recording, voice recorder, nearly 10 functions such as video output, mobile hard drive, digital camera add-on function have won the title of “Almighty King of Digital Entertainment” from just one time.
