His works is very simple, the key to the oh. Anything the most important principle. He is composed by a large number of independent of the photosensitive element, and when we pressed the shutter, the light passing through the lens exposure on the photosensitive elements arranged in accordance with the matrix, the light was turned into the charge. The amount of charge on each component depends on the intensity of the light it suffered, that our traditional camera like. Then, each component in turn information to the converter, analog signals through analog converter into digital signal, digital signal compression to a certain format into the cache, this time, a digital photo was born. The cell phone jammer factory has the high output of cell phone blocker .
Since 2001 the first 256-color color cell phones Ericsson t68 since the advent of color cell phones in a short period of four years is almost accounted for the lion's share of the cell phone market, play a video file additional features for color cell phones are popular, However, different cell phones support different video formats. Such as smart cell phones tend to support the RM WMV, AVI video, while the ordinary cell phone is more popular to play 3GPP MPEG4 format video. 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. The intermediate inspection of cell phone jammer will be carried out soon.
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. 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. The normal operation of cell phone jammer should be ensured at first.
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. 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. The normal operation of cell phone jammer should be guaranteed in the first step.
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. 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. cell phone jammer has the ceiling mount design.
