Mike kevin Guest | Portables with only audio playing functions seem to get ever further away from people¡¯s increasing demands. This provision gap helps herald in a new generation of entertaining gadget ¨CMP4 player.
Though MP4 player has been around for a period of time, many people¡¯ knowledge about this relatively new gadget is only a ¡®video player¡¯. Here I¡¯d like to add some in-depth know-how about MP4, hope it will help newbies here.
1. MPEG Standard
First, what is exactly MPEG is? MPEG, Moving Picture Expert Group, is the format of VCD, SVCD, DVD. This format applies lossy compression to reduce redundant info in active images, and to express it more clearly, MPEG makes use of the fact that the two contiguous images are almost the same, to choke out the redundant info of the latter image ,as so to meet the compression aim( the highest compression reaches 200:1).At present, MPEG suite family members are MPEG-1,MPEG-2,MPEG-4.The other two MPEG-7 and MPEG-2 are right now under development.
2. MPEG-4 Standard
MP4 players certainly support videos in MPEG-4 format. MPEG-4 is greatly different MPEG-1 and MPEG-2. Other than a compression algorithm, MPEG-4 is also an internationally recognized standard aimed at meeting demands of other compression technologies, such as digital TV, interactive drawing applications, interactive multimedia, etc. MPEG-4 integrates lots of multimedia application into a single framework, so as to provide a standard algorithm and tool for multimedia communications and application environment, thus establishing a unified data format that can be applied in many application fields such as multimedia transmission, storage and search, etc.
3. MP4 Player
The first MP4 player in the world, JukeboxMultimedi-a is rolled out by Archos. Ever since late in year 2002, Archos launched the first MP4 player, people¡¯s attention has been directed from kind of obsolete MP3 to the new elite MP4, and the market for MP4 player has experienced drastic exchanges, with more and more manufacturers flocking to share this lucrative cake.
iPod has been always maitaining its classic elegance, and in year 2005 , rolled out iPod video series. For its powerful functions and unique design, iPod 30G/60G have grabbed quite a large share of the market. Later on, Sony, Sumsung and iRiver have also explored their own MP4 market. PSP, a big profit maker for Sony, not only provides game lovers with new exciting games, but also a new entertainment genre, enjoying movies on the go. There are many other choices for playing MP4 videos, such as PMP, PMC, etc. For example, iRiver PMP-100 integrates audio, video, picture, and games into that one cute gadget, supporting MPEG4/MPEG2 videos, thus making ¡®portable cinema¡¯ come true.
4. MP4 format converter
After we¡¯ve got a MP4 player, the next question to cope with is how to make the player more friendly with other formatted video, since currently videos in MPEG-4 format are anything but many. As you know, videos come in many formats, such as WMV, WAV, WMA developed by Mircosoft, RM, RMVB, RA from REAL, etc. If you have these videos at hand and want to play on your MP4 players, there must be some chore of conversion. If you google for the needed tool, there pop up many choices. For example, ¡®Super Converter¡¯ affords powerful functions, and supports many formats, of course MPEG-4 included. There is another tool attracting my attention, ¡®Xilisoft MP4 Converter¡¯, an expert with exclusive designs for MP4 players. What¡¯s more appealing is its special output choice setting for different MP4 players, such as Archos, iRiver, PSP, iPod, Creative ,thus more customized design for mainstream hardware users.
With this general knowledge about MP4, hopefully you can give your gadget full play of its versatile functions and make it more worth your money.
