    Abstract
  • High performance network over coax (HINOC) is a new technology of coaxial cable access, used for next generation broadcasting network. It can be used in triple play and the two-way cable TV network of digital and upgrade. The system is made up of HINOC bridge (HB) and HINOC modem (HM). In order to improve software function, it is necessary to update embedded software. File transmission and FLASH ROM program are basic processes in upgrades. In consideration of problems existed in widely used upgrades system such as low efficiency of encryption transmission and the lack protection for hardware failures, the system design introduced mechanisms such as coding and decoding of delta information, cryptography, file verification, and abnormal protection. According to the experimental results, the design meets requirements of HINOC in terms of efficiency, security and reliability. Information safety can be effectively protected, and the embedded devices can maintain basic function when abnormal problems happen.
