Abstract: A media docking device includes an input circuit, an output circuit and a processing circuit. The input circuit is electrically connected to a media source device for receiving media data. The output circuit is electrically connected to a media play device. The processing circuit is electrically connected to the input circuit and the output circuit. The processing circuit determines if a verification procedure is passed. If the verification procedure is passed, the processing circuit transfers the media data to the media play device. If the verification procedure is not passed, the processing circuit limits a transmission of the media data, such that the media data will not be completely played by the media play device.

Abstract: A media docking device includes an input module, an output module and a processing module. The input module is electrically connected to a media source device for receiving media data. The output module is electrically connected to a media play device. The processing module determines if an instruction is received from the media source device or a remote device. If the instruction is not received, the processing module transfers the media data to the output module to transmit to the media play device. If the instruction is received, the processing module limits a transmission of the media data according to the instruction, such that the media data will not be completely played by the media play device.
