The Design And Implementation Of STB Software Upgrade

With the rapid development of network technology and chip processing capacity,the user more and more demand for set-top box use,use the experience to higher.Set-top box as a household electrical appliance class,keep hardware and continuously upgrade software way became the most convenient set-top box industry the most economical choice.Based on SiChuan JinWangTong Electronic Science and Technology CO.,LTD production based on Hisilicon Hi3716MV300 main semiconductor chips DVB and OTT STB hardware development platform.Software development platform for Linux 2.6 operating system,the system provides tailored on some not commonly used in the set-top box to the function of the version.In this paper,the set-top box that is commonly used in upgrading ways are expounded in detail,including USB upgrade,the upgrade of TS and network upgrades the detailed design,implementation and modification.The goal of this article is in the selected hardware platform will be the three STB software upgrades are designed and implemented.USB upgrade way is in the boot insert USB storage devices,can detect when the phone is switched on after the upgrade information into the loader began to USB upgrade;TS stream way of upgrade is as long as the front play upgrade stream,set-top box on startup or boot can be detected after upgrade information,satisfy the conditions into the loader for OTA upgrade;Network upgrade way is in the set-top box connected to the network,after initiative to update information on the server,the detected qualified after the upgrade of information,network upgrades.This article USES the method of modular design,the research content is divided into upgrades information detection module,data download module,writing data module,upgrade the security module and assist upgrades n module.After all the modules realize comprehensively with the set-top box system debugging,after confirm the software meet the design requirements,will be put into the market,the set-top box to test market and users,according to the market feedback correction is perfect.
