Of course, this can not be called a walkman. Combined with the video play, the new generation products can be called as personal digital entertainment terminal units. On behalf of such products is the digital audio MP4 player which is currently under continuous development. What advantages and disadvantages do digital audio MP4 players have?

What is digital audio MP4 player?

First you need to understand: what is digital audio MP4 player? MP4 is the abbreviations for the MPEG-4 compressed format, and MPEG-4 is a video format which supports different resolutions from 320×240 to 1280×1024. The reason why portable media players named digital audio MP4 player is such products can support the MPEG-4 format.

What format does video can digital audio mp4 player play?

Different digital audio MP4 players are able to support different video formats. Most products can support MPEG-4, AVI, ASF, WMV and other video file formats. Of course, many products can also support MP3, WMA and such audio file formats. But in fact, most products don't fully support these formats. Taking the AVI format as an example, this is only a general AVI, including DIVX, XVID and many other formats, a lot of digital audio MP4 players don't support these formats very well.

Even within the scope of the support format files, digital audio MP4 player may not be able to play out, this involves the problems of resolution. When encountering some documents which are different from the default resolution of the machine, the digital audio MP4 player will not be able to play normally. Many friends who have MP4 player products often encounter such a situation, the digital audio MP4 player can't play the video downloaded on-line, or there is no image only sound and so on. As for the popular video file format, we have to mention the RM format naturally, and there are a lot of resources of such video files online. Because of copyright issues, basically digital audio MP4 player does not support RM format, this has hampered the development of digital audio MP4 player to a great extent.

What screen does digital audio MP4 player often use? What kind of screen is the best?

Apart from the CPU and operating system, the digital audio MP4 player has another focus-the screen. It is not the same as MP3, and digital audio MP4 player is designed for video play, so the quality of the screen has a direct impact on the effect of video play. At present, there is no uniform standard about the screen of the digital audio MP4 player, the specification, size, color and brightness are different. The size is about 2.5 - 3.8 inches. In order to show the effect, the larger screen is necessary, we all know a truth: under the same conditions, the bigger screen shows better results. There are many kinds of screen specifications, such as CSTN, TFT, etc. are all used. Next let us look at the characteristics of the screen specifications.

First CSTN:
The characteristic of the CSTN screen is that it has a wide viewing angle and high-capacity which are quite good in the video play. But overall, the technology of CSTN is lagging, the color and the response time are rather bad, most of the digital audio MP4 players with CSTN screens are low-end products.

Second TFT:
TFT specification is a kind of active-matrix liquid crystal display screen. There is a light source on the back substrates of the screen, which can independently control each pixel point on the screen. The response time of TFT screen is also significantly reduced, which is generally less than 80ms. TFT screen has good color saturation and contrast ratio, which is widely used in the digital audio MP4 players products, but the disadvantage is that it has relatively high power consumption, this is also one of the reasons why many digital audio MP4 players can only use for a comparatively short time.

Third LTPS TFT:
This is a new generation of technology derived from TFT screen, the full name of LTPS is "Low Temperature Polycrystalline Silicon". Compared with TFT screen, each indicator of LTPS-TFT screen has been greatly improved, but the price of LTPS-TFT screen is too high, most digital audio MP4 players with this type of screen are high-end products.

In addition, in color, currently many digital audio MP4 player products use 65K color display. But some high-end digital audio MP4 players have begun to use the 260,000-color TFT display screen. Of course, when other things being equal, if the color display of the screen is higher, the color degrees will be better, when you play the video the effect will be better.

In addition, many digital audio MP4 players also have a number of common functions, such as FM radio, MIC recording, etc.

Because most digital audio MP4 players have a large capacity of hard drive, huge storage space, with the card reader slot, it can be generally used as a digital companion, you can back up files on the memory card as digital cameras and very good DV digital partner as well.

In the conditions of significant upgrade of CPU, screen, etc., digital audio MP4 players have also been added to a number of functions, such as JPG picture browsing and so on. Some digital audio MP4 player products have internal or external cameras, and some provide the function of connecting television to play video and record programs from TV, etc. These features have extended and enriched the functions of the digital audio MP4 Players.
