Here is the product application of china cell phone jammer

Called the 3GPP 3G Partnership, Protect the Chinese translation for the Third Generation Partnership Project, 3GPP video is a multimedia standard, support for MPEG-4 and H.263 video coding agreement with ACC Advanced Audio Coding and AMR Adaptive Multi-Rate audio standards. See here may be feeling very strenuous. It does not matter, this is just a definition of it. 3GPP video that we usually see the use of H.263, the AMR NB coding protocol, it can provide 30 frames / sec in the low rate of 128KB / S smooth screen, the cell phone can be online on-demand. The cell phone jammer   has stable quality and performance with repair rate not more than 2%.
In terms of the current situation applies to cell phones with small memory capacity, 3GPP video format is very easy to send MMS MMS, most of the support for video recording cell phone supports video playback in 3GPP format. In 1998, the founding of the United Nations International Organization for Standardization ISO and the International Electrotechnical Commission IEC MPEG encoding standard. Stands for Moving Pictures Experts Group Chinese translation of the Moving Picture Experts Group. They developed three versions of MPEG, respectively, MPEG1 the MPEG2 MPEG3 which MPEG3 our daily often have access to all of us are familiar with is the MP3. Subsequently the organization to develop the two new image compression standard is as MPEG4 MPEG7. One of working frequency of common  cell phone jammer   in the market is 869~894MHz.
MPEG4 is a compression standard for ultra low bit-rate moving images and language. His advantage. MPEG4 compression ratio high, the low bit rate transmission of video. Small compared to MPEG1 the MPEG2 MPEG4 encoder optimized image files, a higher compression ratio, better clarity. Can reach up to 768 * 576 definition, this definition has been close to the DVD picture. We may in this regard is not too concerned about, then talk about the application. MPEG4 compression algorithm Divx video coding technology to the 120-minute movie can be compressed 600MB, you can also compress a DVD to two CD-ROM, so that we do not have to use the DVD device to enjoy DVD-quality images . For the application of mobile video, MPEG4 smaller bandwidth for video transmission. 1900~1990MHz is also contained in the working frequency of  cell phone jammer  .
The cell phone's hardware can not be compared with the computer, so MPEG4 on the cell phone does not like on a computer so powerful. Many camera cell phones can capture low-resolution MPEG4 video, the same, and now most of the cell phones support download and play MPEG4 video. RM famous Real Networks Inc. to develop audio and video compression specification. RM format all known as Real Media. It contains the file format of the audio stream real audio and video streaming file format real video file. He is a compression format developed by Real Networks Inc., a major for the online real-time transmission of video and audio information in the low rate. The DC-DC converter input voltage is used for  cell phone jammer.
The smartcell phone can install real player to support to play RM video on our 7710 with. . Nokia is generally the software bundled on the cell phone does not need our own independent installation. Some members reflect the REAL version of our own backwardness want to upgrade but there is no way to upgrade. The mobile version of the real single function on a computer that can play RM format can not be used in cell phones. REAL cell phone more stringent requirements of the RM file encoding rate, which is how some members say find a film on the cell phone but can not play, play out of a sound image, and so on. Because of this. Here is the product application of  china cell phone jammer.
