1. An interface accessing method, wherein the method is applied to a display apparatus, the display apparatus comprises an on-screen display board card and a field-programmable-gate-array board card, the on-screen display board card is connected to the field-programmable-gate-array board card via an interface, and the method comprises:
by the on-screen display board card, when the on-screen display board card receives a viewing instruction of an audio-inputting-device-volume interface, accessing the interface periodically according to a predetermined accessing mode, wherein the predetermined accessing mode comprises, at each of periods, after each time of performance of a first preset time quantity of interface accessing operations to audio-inputting-device-volume data, performing a second preset time quantity of interface accessing operations to video-channel-access-state data; and
by the on-screen display board card, via the interface, reading alternately the audio-inputting-device-volume data and the video-channel-access-state data from the field-programmable-gate-array board card.
