The WM signal formation device, the computer legible record medium which records the computer feasibility program and the said program in order to execute WM signal formation method and WM signal formation method, the digital television device which includes the electronic spacing pad device, and the said electronic spacing pad device

摘要

The WM signal where tolerance and quality are improved is formed, the device in order to imbed the electronic spacing, program and memory medium and the digital television device which includes electronic spacing pad function are offered. Vis-a-vis the real time contents device 10 in order to form the WM signal which is imbedded as the electronic spacing the input expedient the input buffer 14 which keeps 12 which inputs the real time contents and the real time contents and, includes with the formation expedient in order to form the WM signal which from the real time contents which are divided corresponds to the estimate strength of the real time contents and the output buffer 18 in order to keep the WM signal which is formed. Formation expedient is formed in estimate expedient 16 in order to do the strength estimate of the aforementioned WM signal and the divided real time contents using the message which imbeds as the electronic spacing the control means including with the expedient 22 in order to form 20 which control the pad and the output WM signal.
