Method for preventing pirating software of sample set top box and set top box

Abstract

The invention relates to a method for preventing pirating software of a sample set top box. Before delivery of the sample set top box, usage limit time of the software of the sample set top box is preset. The method for preventing pirating software of the set top box includes judging whether the sample set top box is used up to the limit time or not when starting to use the sample set top box, if not, letting the sample set top box work normally; if yes, sending and executing command of erasing software codes of the sample set top box so that the sample set top box can stop normal work; resetting the software codes by updating so that the sample set top box can work normally again; and executing the above steps to reset the software codes and erasing the limit time if the sample set top boxes are produced in batch. The invention further provides a set top box utilizing the method for preventing pirating software of the sample set top box. The method for preventing pirating software of the sample set top box is simple and easy to realize, low in cost and better in pirating preventing effect and has no effects on the equipment performance.

Description

technical field [0001] The invention relates to the technical field of set-top boxes, and more specifically, relates to a method for preventing piracy of software of a set-top box prototype and the set-top box. Background technique [0002] With the gradual popularization of digital TV, the set-top box technology is also constantly developing, and more and more people enjoy more TV program services through the set-top box. Set-top box manufacturers often provide customers with set-top box prototypes when selling set-top boxes. Without protection, the prototypes are easy for criminals to steal software and use them directly, and carry out pirated production, thus damaging the interests of set-top box manufacturers. Therefore, the set-top box prototype needs to be protected to prevent its software from being stolen. Existing software anti-piracy methods mainly include: [0003] Through the logo character method: the so-called logo character method means that special characte...
