information about it.
MP3: is a kind of audio encoding, and now refers to playback MP3 music files to
the player, but also most of the population for MP3, MP4, MP5 collectively.
MP4: is a use of MPEG-4 multimedia computer files format to store digital audio
and digital video-based. But usually now be interpreted as MP4 player, basically
nothing with the video players have been known as MP4. However, because of the
current functions of these players did not clearly defined, it comes with the
default screen is to meet the needs of video at any time. Need to remind you, it
can also be known as it is called PV. (Personal Video Player, personal video
player) can also be called the PMP (Portable Media Player, portable media
players).
MP5: Following a large extent, MP3 and MP4 from the business after a concept
coined by the fact mentioned by MPEG-5 format does not exist. It is mainly from
Chinese manufacturers to launch a well-known video formats, it is also only part
of the domestic manufacturers recognized digital. Than the MP4 compared to the
most fundamental difference is the addition of network resources, the most
abundant RM, RMVB format, as well as more avi, asf, dat, etc.. As a result of
this distinction is also made consumers MP4 and MP5's a vague concept, in fact,
both refer to the video player. To sum up, is now the major players are still
divided into two types: pure sound quality MP3 and video MP4, basically the
machine-based music can be collectively referred to as MP3, and to see that video
was mainly for the MP4.
MP3 Detailed terms
The mainstream of the current MP3 market, the light can be divided into the
amount of memory on the machine may bring their own memory and the largest
expansion of memory two. If the popular theory to RMVB, TV-OUT, CMMB mobile TV,
so a lot of letters of the alphabet, composed of terms for a "layman" is not
confusing like it is indeed a very difficult task. So for everyone we will
explain these common features to you one by one, as long as the basis for a
serious look at zero to ensure that the trainees can not be kept!
1) audio formats
Comparison of the mainstream of the current audio format: MP3, WAV, WMA,
AAC, OGG, FLAC, APE, of course, we are the most commonly used for the previous
several useful basically have to download songs. It should be noted that: OGG and
FLAC is a lossless double-music format, MP3 is the pure tone to show off the
importance of good quality weight.
2) video formats
At present, the network's more popular video format: MPEG-4, AVI, DAT, MPG,
WMV, 3GP, K3G, FLV, and now the most popular RM, RMVB format. Of course, the
object of focus of attention in this also need to be detailed. vb in rmvb means
Variable Bit Rate (can change the bit rate), compared with the previous
generation rm format to clear a lot of pictures, the reasons for the reduction of
the static picture of bit rate, can be Player RealPlayer software to play. Then
translated into user-friendly is that the current network can be downloaded to
the basic video of most of the format, if you buy a player does not support the
format, the future may want to convert the format will be much trouble.
(C) MP3 explain common features
1) memory
Popular early 32M, 64M such a small-capacity MP3, but from 2008 onwards, if
a 1GB capacity MP3 is also the name of streets, then you can BS the capacity of
its pocket-sized too. Now the mainstream player in the capacity of the basic
positioning 4GB, of course, 8GB, 16GB and 32GB capacity of the super-whether it
is necessary you need to look at the preferences of their respective. Of course,
taking into account the number of users will find the amount of memory not
enough, it will also set aside space to expand capacity, if that not enough
capacity, then add the last of the SD card is 4GB meet basic needs.
2) TV-OUT
TV-Out refers to the card's terms, it has the output signal can be connected
to the television-related interfaces. In other words, its role is to be used in
place of the basic DVD's. In fact, this role in many of my friends seem to be a
function of chicken, but since there is naturally a need for it. Now DVD drive is
a relatively cheap price, but taking into account the disk to see if Mr. or
audio-visual shop downstairs rent or to buy only the basic is very difficult to
avoid the cost versus the. However, the introduction of this feature can allow
users to download the network has the film, television or video can be home with
us to connect the TV, which is very convenient.
3) FM launch
Members referred to the basic FM radio all know, but the FM launch function
for the rookie a lot of it is very strange. In fact, it is a personal micro-radio
stations, can be Discman, MD, MP3 (including Apple iPod) and other portable
audio, video player audio signals into high-fidelity FM stereo wireless FM signal
transmission from motor vehicles or as the radio home receiver, you can enjoy
stereo music, so the music to a "great diversion of the course of events." This
feature is more appropriate car owners to use MP3 in the car a little on the high
side of the application to some.
4) CMMB mobile TV
CMMB, called the China Mobile Multimedia Broadcasting, is the first set of
independent research and development-oriented multi-media vehicle or a handheld
mobile terminal systems. Currently involved in the mobile terminal for the
players, mobile phones, TV bar and GPS, but the scope of application is the most
extensive areas of player. From the beginning of 2008 during the Olympic Games
more into our lives, because it is not all cities can support, so you want to buy
the feature for the player friends also need to find out whether or not their
city will accept to the signal.
5) TTS function
TTS (Text-to-Speech) speech synthesis technology is referred to, also known
as text-to-speech conversion technology, or text-to-speech conversion system
means any combination of the use of computer text files into sound files, and
through the sound card, telephone multimedia devices such as audio card sound
output to the technology, a simple machine that is to allow text information to
"read" them. This feature is more appropriate student friend, in the past, can
only be used to listen to MP3 music, and now want to back to the ancient
fertility, which would place the text, can be recited as a form of fun.
