Abstract—Based on Markov model, this paper analyzes a soft standby's reliability and safety in PUSH system for digital TV, which is constituted by two PUSH VOD severs working on master-slave mode. It illustrates 5 interesting rules that can guide us to design a more reliable and more secure system. We will see some key parameters that is positive correlated with the reliability may be negative correlated with the safety at the same time. What's more, it shows that using different algorithm for mutual checking can hold system's safety even though each algorithm may be not so efficient. Profit evaluations of such hot standby and advices to design are also given.
