SAFETY SYSTEM IN REMOTE PARTICIPATION TO DIALOGICAL GAME INSPECTING TIME SERIES OF EVENT
Document Type and Number:
Japanese Patent JPH0768051
Kind Code:
A
Abstract:
PURPOSE: To prevent an unfair practice by starting a count of continuous time intervals by a safely protected processor by a message of a transmitter, finishing it at connecting time to a central computer from a game machine for an answer, and verifying whether or not prescribed respective period lengths during this time can realize the prescribed relationship. CONSTITUTION: A game machine counts a period length Tr12 regulated by time T1 to receive a message and time T2 when a TV viewer answers and a period length Ta25 regulated by the time T2 when the viwer answers and time T5 when an answer is sent to a transmitter/central computer. It also respectively counts a period length Ta35 between an answer time limit T3 and the time T5 and a period length Ta15 between the time T1 and the time T5. Whether or not a fuction of a value of an allowable range (Tr25>Ta35, and Tr12+Tr25=Ta15±) is realized during these counted period lengths (Tr25, Ta35, Tr12 and Ta15), is verified, and when it is not realized, an answer is rejected.
