Blog:The “core” MP4
From the principle, MP4, but with little difference between MP3, both hardware performance from far, mainly because the video playback function, Divx Xvid and etc.
The broadcast mpeg-4 requirements, the CPU and DSP high processing capacity, and should have certain system memory, Divx encoder, encoder developers came to use the main 400MHz more computer to complete the decoding chips, MP4 requirement has high computing performance, many MP4 luxuriant interface will consume plenty of system resources, MP4 video data and image is not only the data processor, now the MP4 or many digital multimedia function and the unity, to realize the function forms, for example, digital video collection, partner, please, FM, DC… Even some MP4 also supports multiple lines. So the MP4 chip requires not only has high computing power and integrated many functions.
Because the core chip making, MP4 high level technology, so the MP4 manufacturers are powerless, these core generally by traditional chip making, Intel, as you design, Sigma TI, even AMD also has introduced the MP4 – special processing chip AU1200. At present the MP4 mainly adopts the scheme is TI Wintel and complete hardware and software solutions.
Texas Instruments, TI (mobile entertainment) is the chip giant, and equipment of the chip giant Intel desktop platforms, because TI start early, so now mostly MP4 are using TI chip solutions occupied most of the market share. Although the hardware have certain standard, but the software system has no unified standard, but all their business development (mostly Linux), this is also one of chaos “made great cause. Now most manufacturers are using TI, major is visible, and Europe and the love of SONY, Toshiba, digital manufacturers.
And Wintel strong-strong union, launched a new standard, the central processor PMC contractor by Intel’s XScale series, Microsoft’s Windows software system is Portable Media Center system, software and hardware are unified standards, fully embodies into Portable Media market, Microsoft Windows system, due to an ambitious Portable Media, the whole framework of open, so can the operating system on the basis of the application software extensions. Wintel antipathy, unified industry standards, to a certain extent FaZhanDian clear direction to MP4. At present the solutions of the support, set, samsung and iRiver innovation etc
