The Thomson Multimedia corporation (France) with the Fraunhofer Institute corporation speech compression system and the file format which were developed.
The Fraunhofer corporation can compress developed on the basis of MPEG Audio Layer-3 which is known with the abbreviation with the system of assuring the improvement of the sound quality and bulk compressibility, while the sound quality like CD is maintained, approximately half of former MP3 in the data quantity.
We have consisted of the combination of the data part which is equal to the MP3 format and the data part which recorded the high frequency limits preponderantly, it can hear even with the former MP3 corresponding player.
As for being able to play back with the mp3PRO non corresponding player because becomes just the MP3 format interchangeable part, at that time as for the sound quality equality to former MP3. Copyright protective technology is not installed MP3 similarly.

| It is the portable equipment which plays back built-in memory and the audiophile of the MP3 type which is recorded to the memory card. Because there is no movable part such as motor different from CD walkman and the like, sound those where it does not fly are the big merit.
Because is same random access possible as other digital media such as CD and MD, it makes the playback list and/or the head it is possible at instant to do to put out. The player who corresponds, to other speech compression type such as other than and WMA type MP3 type it is many. In addition, recently, when the portable telephone and the digital camera etc have MP3 playback function, it is.
Also the CD player who can play back the MP3 type file which is recorded to CD is sold, this is one kind of MP3 player. When CD is used for the record media, besides the fact that than the amount usual CD where the data quantity around 1 tunes is small it is stronger in the sound flying, record time of 10 times that CD it is possible to be able to give. |

The Thomson Multimedia corporation with the Fraunhofer Institute corporation (Germany) speech compression system and the file format which were developed.
The Fraunhofer corporation can compress developed on the basis of MPEG Audio Layer-3 which is known with the abbreviation “of MP3”, with the system of assuring the improvement of the sound quality and bulk compressibility, while the sound quality like CD is maintained, approximately half of former MP3 (the original data 1/22) in the data quantity.
We have consisted of the combination of the data part which is equal to the MP3 format and the data part which recorded the high frequency limits preponderantly, it can hear even with the former MP3 corresponding player.

Multimedia > animated picture > MP4 |
| One of the file format which houses the compressed animated picture data of MPEG-4 type. It is stipulated with the section of Part MP4 with the derivative format of ISO/IEC 14496 Part 12 which is decided on the basis of the file format of media technology QuickTime of the Apple corporation, is designed to be the structure which follows many of former QuickTime type.
Not only animated picture of MPEG-4 type to retain the animated picture of MPEG-2 and MPEG-1, it is possible also in the MP4 file in addition, the sound of AAC and MP3 etc, multiplexing the still picture and the like of JPEG and PNG, etc because it is possible, to house, that it does not try analyzing inside, you do not understand the data of some kind of type has entered. But as for the extension of the standard MP4 file when is only animated picture, when is only sound, there are also times when “.m4a” is used. The case where the media is handled by the portable telephone also 3GPP type and the 3GPP2 type which are standard file format have become the derivative format of MP4, the extension is each one |

Microprocessor > x86/Intel > interchangeable processor > mP6 |
The x86 interchangeable microprocessor which the RiSE Technology corporation announces in 1998 November (MPU).
High efficiency is actualized even at low clock frequency by the fact that integer arithmetic unit 3, floating point arithmetic unit 2 and MMX unit 3 and, loads the execution unit of very many orders, executes plural orders simultaneously. As for mP6 which operates with 200MHz, it is a match to the efficiency of Pentium II 266 - 300MHz.
Excluding the function which other many MPU has adopted, the paragraph folds the size of the tip/chip small, electric power consumption is smaller than the competitive product of other companies. In addition, because low it can put out high efficiency with the clock, if it compares with the product of the same efficiency,
