Nancy Codec is mainly the result of research and development by Office Noa in Japan. Currently, the technology is adopted. In addition to Japan â€™s J-Phone and NTT DoCoMo, there are major telecom operators in Asia, Europe and the United States including China Mobile Communications Corporation. The stage of testing or research. Traditional video compression requires a high-speed CPU or a dedicated processing chip, which not only takes up space, but also increases power consumption. Relatively speaking, software solutions like Nancy Codec do not need high-speed CPUs or dedicated processing chips, so they can solve the mobile communication market's demand for mobile devices with video processing capabilities.
Nancy Codec is a technology independently developed using the concept of SMSP (Structure Meta Sale Polygon). The principle is to divide the mobile image into models of many different shapes and sizes, and then compress it. Because of the new simple four-calculation algorithm, it is not Motion detection (MoTIon EsTImaTIon) and discrete cosine transform (DCT) are required, so the calculation amount is small and the transmission rate is fast.
Nancy Codec is a compression technology with considerable advantages. Because Nancy Codec uses software to achieve video compression, the hardware processing capacity is only 10% of MPEG4, and the operation speed is twice as fast as MPEG4, and the compression rate is ten times of MPEG4. One-half, so the existing mobile communication network can be used to transmit video. At present, many companies have launched DSP chips that support Nancy Codec, including Texas Instruments and Epson. In addition, there are many telecommunications companies behind it, including Japan â€™s J-phone and China Mobile. However, although Nancy Codec does have advantages in the development and application, it also has some problems: because Japan Office NOA company exclusively owns this technology, it cannot be technically open, so it is not conducive to the further development of this technology On the one hand, it may be difficult to promote the application due to conflicts of interest of all parties.
