    • The present invention relates to a protection device for a conditional access chip within a settop box, in which it can prevent the conditional access chip within the settop box from being duplicated and distributed due to malicious detachment. To prevent epoxy from being melt due to heating of a top surface of the conditional access chip within the settop box, protection means having adiabaticity and a predetermined size is laminated on the top surface of epoxy. The protection means includes a protection plate, as a flat panel having a predetermined thickness, which is laminated on the top surface of epoxy that prevents the detachment of the conditional access chip.
    • 本发明涉及一种用于机顶盒内的条件接入芯片的保护装置,其中可防止机顶盒内的条件接入芯片由于恶意分离而被复制和分发。 为了防止环氧树脂由于机顶盒内的条件访问芯片的顶表面的加热而熔化,在环氧树脂的顶表面上层压具有绝热性和预定尺寸的保护装置。 保护装置包括保护板,作为具有预定厚度的平板,其被层压在防止条件访问芯片脱离的环氧树脂的顶表面上。
