And dynamically adjusting ARC sound delay data, namely ARC _ Audio delay according to the obtained AVdelay value, and ensuring that the AVdelay range is within-30 to +100ms (-leading sound and lagging sound), and the human ears cannot hear the sound and the picture out of synchronization within the range. This ARC _ AudioDelay is compared with the local horn AMP _ AudioDelay to obtain Δ AudioDelay. The local loudspeakers AMP _ AudioDelay of different channels with different timemings are known, and AMP _ AudioDelay + Δ AudioDelay are the ARC sound delay data of other channels. The data can ensure the synchronization of the power amplifier sound and the television picture.
