Nancy Codec Compression Technology Introduction

Most of the compression techniques used in the current video field are similar to the MPEG series. Although MPEG-4 or H.264 / AVC has achieved higher compression ratio, it is more difficult to implement video transfer on this compression in 2.5g or even 2G mobile communication networks, so in general, mobile communication The video service is mainly to lock the service provided after 3G popularity. However, if you can provide video services at 2G or 2.5G networks, you will bring huge benefits to your telecom operators, which will also enable mobile users to enjoy more and more richer mobile services. Nancy CODEC technology is developing for this purpose. Nancy Codec is mainly based on the results of Japan Office NOA. In addition to Japan J-Phone and NTT Docomo, there are also major telecom operators in Asia and Europe and America, including China Mobile Communications. Test or study the phased phase. Traditional video compression requires a high-speed CPU or a dedicated handle, not only space, but also increases power consumption. Relatively speaking, there is a software solution like Nancy Codec, there is no need to have a high-speed CPU or dedicated processing chip, so it is possible to solve the needs of the mobile communication market for the mobile device with video processing. Nancy CODEC mainly develops the technology independently developed by SMSP (Structure Meta Sale Polygon), which is the principle of dividing motion images into models of different shapes and sizes, and then compressed, because of the new simple four algorithm, no Motion Estimation and discrete cosine conversion (DCT) are required, so the amount of operation is small and the transmission rate is fast. Nancy Codec is a compression technology with considerable advantage, because Nancy Codec is compressed by software, so hardware processing power is only 10% of MPEG4, and the compression speed is 1 times faster than MPEG4, and the compression ratio is MPEG4 ten One of them, so the video can be transmitted using the existing mobile communication network. There are currently many companies to launch a DSP chip that supports Nancy Codec, including Texas Instruments, Epson. In addition, there are also many telecom operators, including Japan J-Phone and China Mobile. Although Nancy Codec does have an advantage in development applications, it also has some problems: Since Japan Office NOA has exclusively owned this technology, it is impossible to technically open, so it is not conducive to further development of this technology, On the one hand, it is possible to promote the development of the application because of the conflicts of all parties. , Reading the full text, the technology area Tektron supports Amazon (AWS) media service, providing quality assurance for end-to-end video IMEC is about to shock the first short-wave infrared (SWIR) band hyperspectral imaging camera 4K super high-definition home theater projector brings HD experience, full of fun Video display system design based on unified calculation architecture technology Apple TV 4K dismantling report: familiar modular components
