Abstract

The present application is a multimedia system and a method for controlling an environment using multimedia files. The system includes: a multimedia controller, a first playback device, a hidden data decoder, and an environment control device. The method includes the following steps: reading at least one multimedia file. and decoding to generate at least a first signal, the multimedia file contains a hidden data, the first signal contains a first hidden signal; playing the first signal; receiving and based on the first signal in the first signal Hiding the signal generates an environment control signal and transmits it to an environment control device; and the environment control device performs an environment control action according to the environment control signal.

Description

Technical field [0001] This application relates to a multimedia system and a method for controlling an environment using multimedia files, and in particular to a multimedia system that can be applied to an electronic billboard and a method for controlling the environment using multimedia files. Background technique [0002] With the popularization and parity of audio and video (audio and video) playback systems, print advertising billboards in many public places have been replaced by flat-panel displays and related audio playback devices that change content and can be switched at any time. However, when the density of on-site advertising billboards is too high, to further attract the attention and attention of the crowd, more environmental control devices and corresponding control methods are required. One of the main purposes of this application is how to develop a multimedia system that solves the above-mentioned lack of existing technology. Summary of the invention [0003] Th...
