It is short for "Personal Media Player" personal media player or "Portable Media Player" portable media player. It also has many aliases: MP4 Walkman, PVP (Personal Video Player).

The most basic function: can provide users with digital video and digital audio experience. In addition, many PMPs currently support many functions such as digital video recording, digital photography, digital video, digital camera companion, digital audio recording, and mobile storage.

Human desires are always endless. That's why there is creation. Let's take a look at these glorious records:

In 1877, Edison invented the phonograph, which can only be heard for 128 years.

In 1889, Edison invented the film, and the image that humans can see is only 116 years.

In 1925, British scientists successfully developed televisions, allowing people to enjoy a visually fresh experience without leaving home.

In 1979, Sony invented the first Walkman, and the originator of personal media players was born. People can enjoy wonderful music anytime, anywhere.

In 1976, Japan's JVC developed and launched the world's first VHS video recorder HR3300, which eventually became the global standard for video tapes, and used audiovisual communication to create a new cultural phenomenon.

In 1972, Philips first developed the world's first video disc VLP. In December of the same year, the MCA in the United States also exhibited similar products.

In 1982, Sony and Philips decided on the standard for the CD format.

In 1984, Sony invented the portable CD player, the first portable digital audio player appeared, and the CD player became more and more popular all over the world.

In 1992, the MPEG standard was born, which determined the compression standard for full-motion images. This standard also became the CD-I format in 1993. Digital video compression is finally born!

In 1993, China's Anhui Wanyan Electronic System Co., Ltd. launched the world's first digital audiovisual product, VCD. get

A deep misunderstanding has been circulating on the Internet: The first PMP was invented by Archos. Hehe, how can Archos Ho De, be able to shoulder this heavy task? But it s just a way for manufacturers to publicize it. In fact, the concept of PMP (Personal Media Player) has been around for a long time, but it was not named at that time. The first portable video product, I don't know how many people still remember, in the early 1990s, it became popular with a product called a portable TV. The earliest portable TVs were about as thick as slabs. When they were put on the TV, they quickly ran out of power. They also had small LCD screens, and many also had radio functions. More famous is Casio's portable TV series.

In 1995, Sega also introduced a TV receiver plug-in on its color LCD portable game machine MD (MEGA DRIVE) nomad, which now seems to be the first PMP with gaming capabilities.

Now if you go to a large electronic mall casually, you should also see this kind of domestically produced LCD portable TV in the corner of a remote counter.

Our neighboring country, Japan, has a deep foundation in the research and development of electronic appliances. In fact, Japan had many portable video player products long before the concept of PMP was born. Japan first entered PMP, and Japan is a sacred place for digital product enthusiasts in the world.
