An advertisement embedded system, an advertisement embedded method, and a recording medium thereof are provided. The system includes a medium providing module and a digital television (DTV) apparatus. The medium providing module is used to provide a piece of advertisement media data. The DTV apparatus includes a digital signal receiving unit, a detection unit, and a processing unit. The digital signal receiving unit receives a DTV signal, and the detection unit detects strength of the DTV signal. The processing unit is connected to the digital signal receiving unit and the detection unit. When the strength of the DTV signal detected by the detection unit is less than a preset value, the processing unit switches a media source of the DTV apparatus from the digital signal receiving unit to the medium providing module, so as to obtain the piece of advertisement media data. |
