METHOD OF DETERMINING AN UNUSUAL BEHAVIOUR OF AN ELECTRONIC APPARATUS, AND ELECTRONIC APPARATUS ABLE TO IMPLEMENT SUCH A METHOD

摘要

Method determines the electronic equipment and electronic equipment of abnormal behaviour, can be realized such method. The invention relates essentially to a kind of methods of the abnormal behaviour of determining electronic device, the electronic device executes an operation, it needs using the electronic equipment (100) about internal reference clock item of information (108), it is characterized in that, it includes each step: comparing the electronic device (100) of the temporal coherence (300) of internal reference clock item of information and span, the temporal coherence of the span determines each temporal information item (li) of storage on the basis of being) in electronic equipment; In internal reference clock item of information and above-mentioned coherent ranges in the case where inconsistent, the relevant item of information of abnormal behaviour of the electronic device is stored. It is for example implemented in digital television decoder according to the method for the present invention.
