Abstract
A multimedia television is provided. The multimedia television includes a video playback apparatus, an audio processing device, M front loudspeakers, a rear audio playback apparatus, and a mixing device. The video playback apparatus is used for displaying a video signal. The audio processing device processes an audio signal into a multi-channel audio signal consisting of M front sub-audio signals and N rear sub-audio signals. Each front loudspeaker plays back one corresponding front sub-audio signal. And, the mixing device mixes the N rear sub-audio signals into a mixed audio signal, which is then wirelessly transmitted to the rear audio playback apparatus. After the mixed audio signal is processed into N rear sub-audio signals, N rear loudspeakers in the rear audio playback apparatus playback the N rear sub-audio signals.
