1. A media streaming device electrically comprising:
a media streaming module comprising a reset unit;
a super capacitor having a first terminal electrically coupled to the media streaming module and a second terminal electrically coupled to a ground terminal; and
a protection module comprising:
a current limiter electrically coupled to the first terminal of the super capacitor, the current limiter configured to receive a power signal to power on the media streaming device and perform current-limiting on the power signal to generate a fixed-current power to charge the super capacitor; and
a disabling circuit configured to disable the media streaming module after the media streaming device is powered on and until the super capacitor is charged to a voltage higher than a predetermined voltage threshold, and configured to transmit a control signal to the reset unit such that the reset unit resets the media streaming module to disable the media streaming module when the voltage of the super capacitor is not higher than the predetermined voltage threshold after the media streaming device is powered on, and configured to stop transmitting the control signal to the reset unit when the voltage of the super capacitor is higher than the predetermined voltage threshold;
wherein the media streaming module is started-up by the fixed-current power for processing media data in a form of a media stream and transmitting the media stream to a media playback device after the disabling circuit stops disabling the media streaming module.
