Discussing and research of HD/SD broadcasting system

According the program-driven high-definition clear file-based broadcast system modeled on the design of the system of the Shaanxi TV Station,this paper focuses on the design and the ideas ahead of the sense,while not avoiding the mistakes.Through the discussion of the superiority and negligence,it does not only finding strong support in the theory,but also verifying the practice on the theoretical method,gaining experience.In the work,it can overcome shortcomings,optimize the system design and the engineering practice.At the same time,colleagues can draw useful things or a warning.
