The present invention relates to the technical field of electronics. Provided in embodiments of the present invention are a set-top box output signal conflict resolution method and a set-top box for addressing a problem in the prior art in which a user cannot watch a satellite program normally, as a result of missing a satellite signal because pulse signals outputted by different set-top boxes undergo signal conflicts due to a small frequency difference therebetween when multiple set-top boxes are connected to a low noise block (LNB) via a power divider, and in which the LNB periodically switches between a high local oscillator and a low local oscillator. The specific method comprises: determining whether a pulse signal transmitted by the set-top box to the LNB conflicts with a pulse signal transmitted by another set-top box to the LNB; if so, adjusting, according to a preset rule, a frequency of the pulse signal transmitted by the set-top box to the LNB, such that the adjusted frequency eliminates the conflict between the pulse signal transmitted by the set-top box to the LNB and the pulse signal transmitted by the other set-top box to the LNB. The embodiment of the present invention addresses the problem of set-top box output signal conflict. |
