In an age that HD MP4 takes most of the market share, the two manufacturers Gemei and Angda work together, and promote a new type of MP4---Geda VX690HD.
The resolving power of the 4.3inch screen is 1920*1080 which is superior to the HD MP4 in the market.
The appearance of this MP4 is designed by the engineers, which breaks the situation that all the MP4 are the same.
The thing should be paid special attention to is Geda VX690HD can play the 1080P-wide format video. Even if the code stream reaches 100Mbs, it can cope with it smoothly, which really can be called to play it without conversion. This capability is what RMVB box has.
Geda VX690HD can read the HD DVD and blue ray DVD (Mini Disc), which solves the problem of the disc source. The good capability of the player comes from the excellent processor core. Geda VX690HD adopts the CCAV5400 chips of Chip China Rock. According to the president of Chip China Rock, the comprehensive ability of this chip is above the AMD5400+, here comes the name 5400. Actually, this is a little modest. The ability of this chip is the same as or stronger than the Intel Core 2 Extreme QX9770. But what does CCAV mean? I don’t know as well.
Geda VX690HD also has the exciting capabilities: Wifi and OTZ.
Wifi can let the users surf the net unlimited at a high speed in the area covered by the network, this is known by lots of players.
OTZ is the short form of Open the Zoo. This is the concept raised by the Global Mobile Equipment Association. Once you have the OTZ means you have got a Laptop, it can link the equipments with a USB interface. Geda VX690HD support switching to the OTZ mood, which simplifies the progresses.
Meanwhile, Geda VX690HD is equipped with the Entel top touch screen; it supports five fingers work at the same time, which is superior to the performance of IPhone.
Have you notice the interface? Geda VX690HD can use the Windos3.1/Windos95/Windos98/WindosNT/WindosXP/Windos2003/WindosVista/Windos7 series operating system. The president of Chip China Rock said that they will add the support of the UNIX system.
The most exciting function of Geda VX690HD is the simulator of the games. It can simulate most of the games in the market, even including the games in the platform of PlayStation. This is closely related to the operating capacity of the chips of Chip China Rock.
The CCAV5400 chip whose main frequency is 5.40GHz which is higher than the common PC is just as its name. Meanwhile, Chip China Rock adopts the manufacturing technology of 4.5namo chips from “SONI”. It integrates 64 cores in the only 1square centimeter of silicon wafer. That is to say, CCAV5400 is a processor is of 64 cores. The chip of the daily Pc that the present common technology produced is only 4 cores to the most, and the 6 cores are still under testament. However, the CCVA5400 has 64 cores. We can say that Chip China Rock has beyond the earth and human beings!
According to the introduction of the main designer of the system structure Hua Xinwei, CCAV5400 has no any video processing modules, but depends on its strong capability to soft decode the videos. We can see from the picture (the sketch map of the single core of CCAV5400) shown below that there is no any video processing parts. Some people say that soft decode is less efficient and less direct than hard decode. It is true. Compared with soft decode, hard decode can indeed save lots of electrical power. In the condition of consuming the same energy, the hard decode has better quality. However, under the frequency of 5.40, whatever video can be played, not mention that it is under 64 cores process. That is to say, CCAV5400 can play whatever the player software can play.
With such a strong chip, lots of films can be played. The more the films, the more space they will take. The storage capacity of the flash MP4 in the market takes the most part. Usually, a film is about between 200 and 800 MB, while the HD film is about several GB. Considering this, Geda VX690HD adopts the solid-state hard drive developed by the eastern data. It is known to us that when the common HD is processing, the disc inside is rotating. While after adopting the new SHDD technology of the eastern data, instead of rotating the disc, the magnetic head rotates. This could protect the atom of the disc from the centripetal force when rotating at a high speed, and this protect the data, meanwhile increases the HD’s capacity. Geda VX690HD uses the 1.8 inch SHDD HD whose capacity is 4TB (4090GB).
It needs not only the capability of playing the video, but also the high-quality audio processing chips. The audile and visual feeling adding the famous movie can only be described by one word --- cool! Geda VX690HD adopts the IMusic12345chip of the Imp3 Company. IMusic12345 is a 32 bit low-cost stereo codec, as well as an audio output chip of high integration and high capability. IMusic12345 provides sufficient power to the each channel of the stereo headset with 10W. What does 10W mean? The power of a common speaker tape is only 0.5W. There is a 5 inch speaker here, whose power is 5W. Its speaker is larger than the headset. The 10 W output is of very strong power, which can be called as luxury set. The users can bravely choose the high level headset, even the high-power subwoofer. It provides the user with the excellent pictures as well as the high level audile enjoyment of the cinema level.
Some people say that there is something wrong with the HD of the VX690HD; they say it is not the solid-state HD. If you are serious, you will fail. There should be some explain. The solid-state HD that VX690HD uses is not the common SSD HD, but SHDD HD. The storage media of the SSD HD is flash memory, while the SHDD HD uses one or more Aluminum or glass disc the same as the HDD HD. The operation process of the HDD HD is the rotation of the disc, and the movement of the magnetic head is very small. As for the operation process of the SHDD HD, the disc is static compared with the HD, and it is the magnetic head moves. Therefore, it is named as solid-state HD. The HD that adopts the SHDD technology increases the HD’s shock resistance due to the irritation of the disc. Meanwhile, because the disc doesn’t rotate, the atom in it will not move due to the centripetal force. Therefore, the SHDD technology takes or put down the atom from the disc by the magnetic head. The place that the atom has been taken is scanned will form a low voltage, which is numbered as 0 in the computer language, and the place with no space is numbered as 1. Theoretically speaking, if one atom that has been taken is a data, then a disc can store a large number of data. But the SHDD technology is not that mature at present, it can only take 10^5 atoms at one time. Therefore, the memory space of VX690HD’s HD has only 4TB capacity.
What does the code “Piacepy” mean? There isn’t such a word in the dictionary, but it reads like something, doesn’t it?VX690HD

The evaluation of Geda VX690HD
(Now it’s time to test the capability of the modem.)
The evaluation started.
The weather is fine today; I went home eagerly for the Geda VX690HD had arrived. I asked the security for the package, put it on the table and did something I would never forget for a whole life--- go to the toilet. (Who is joking? Nobody will have the intension to evaluate something if he wants to go to the toilet.)
I unfolded the package, and the MP4 appeared. This one is very different from the other MP4. Other packages are of single color, while this one is pretty good. It is true that this MP4 has breaks the same appearance of the regular MP4. For it is a model machine, there are the words “No selling” on it.
Compare the package of Geda VX690HD with the package of Gemei X-690HD, AngdaVX787 and Angda 767.
