5. The media docking device of claim 1 , further comprising:

a signal enhancement module, configured to perform an enhancement procedure on the media data,

wherein the processing module is configured to control the signal enhancement module to decrease a signal-to-noise ratio of the media data such that the media data is not completely played by the media play device.

6. The media docking device of claim 1 , wherein the processing module is configured to transmit a display instruction to the media play device to turn off a backlight module of the media play device or decrease a contrast ratio of the media play device.

7. The media docking device of claim 1 , wherein the media data is video data,

wherein in a multi stream transport mode, the processing module is configured to modify a sideband message such that the video data is not completely played by the media play device.

8. The media docking device of claim 1 , wherein the media data is compressed video data, and the processing module is configured to modify a parameter of a display stream compression such that the compressed video data is not correctly decoded by the media play device and the media data is not completely played by the media play device.

9. The media docking device of claim 1 , wherein the input module comprises:

a control unit, configured to provide another media data to the processing module, wherein the processing module is configured to transfer the another media data instead of the media data to the output module such that the media data is not played by the media play device.

10. A media transfer method performed by a media docking device, the media transfer method comprising:

receiving media data from a media source device;

determining whether an instruction is received from the media source device or a remote device;

if the instruction is not received, transferring the media data to an output module so as to transmit the media data to a media play device; and

if the instruction is received, the processing module is configured to limit a transmission of the media data according to the instruction to perform a scramble procedure or an error correction procedure such that the media data is not completely played by the media play device, wherein the scramble procedure is different from a default scramble procedure of the media data, and the error correction procedure is different from a default error correction procedure of the media data.

11. The media transfer method of claim 10 , wherein the media data is video data which complies with a specification of a digital display interface, the digital display interface defines a blank identification, and the step of limiting the transmission of the media data according to the instruction comprises:

modifying the blank identification such that the media data is not completely played by the media play device.

12. The media transfer method of claim 10 , wherein the media data is video data comprising a frame, and the step of limiting the transmission of the media data according to the instruction comprises:

modifying at least one of content, brightness and contrast ratio of the frame such that the media data is not completely played by the media play device.

13. The media transfer method of claim 10 , wherein the step of limiting the transmission of the media data according to the instruction comprises:

modifying a communication authentication procedure between the output module and the media play device such that a connection between the output module and the media play device is not established and the media data is not completely played by the media play device.

14. The media transfer method of claim 10 , wherein the step of limiting the transmission of the media data according to the instruction comprises:

controlling a signal enhancement module to decrease a signal-to-noise ratio of the media data such that the media data is not completely played by the media play device.

15. The media transfer method of claim 10 , wherein the step of limiting the transmission of the media data according to the instruction comprises:

transmitting a display instruction to the media play device to turn off a backlight module of the media play device or decrease a contrast ratio of the media play device.

16. The media transfer method of claim 10 , wherein the media data is video data, the step of limiting the transmission of the media data according to the instruction comprises:

in a multi stream transport mode, modifying a sideband message such that the video data is not completely played by the media play device.

17. The media transfer method of claim 10 , wherein the media data is compressed video data, and the step of limiting the transmission of the media data according to the instruction comprises:

modifying a parameter of a display stream compression such that the compressed video data is not correctly decoded by the media play device and the media data is not completely played by the media play device.
