Detailed Description
Please refer to fig. 1. Fig. 1 is a block diagram of a media streaming device 10 and a media playing device 12 according to an embodiment of the present invention. The media streaming device 10 is configured to be electrically coupled to the media playing device 12 to provide the media stream MED to be played by the media playing device 12.
In one embodiment, the media streaming device 10 may be, for example, but not limited to, an over-the-top set-top box (OTT STB) or a television stick (TV stick). The media playing device 12 may be, for example, but not limited to, a television.
The media streaming device 10 includes: a media stream module 100, a super capacitor 102, and a protection module 104.
The media stream module 100 is configured to provide a media stream MED. In one embodiment, the media streaming module 100 may include, for example, but not limited to, a processing unit, a graphics processing unit, and a network communication unit capable of accessing the internet, such as a WiFi communication unit (not shown), to connect with a remote server, access media data including video and audio in the remote server, and provide the media data to the media playing device 12 in the form of a media stream MED for playing after processing.
The super capacitor 102 has a first end electrically coupled to the power supply path 110 and a second end electrically coupled to the ground GND. In one embodiment, the super capacitor 102 is, for example, but not limited to, an electrochemical capacitor with a high energy density, which is hundreds or thousands of times higher than the typical capacitance.
The protection module 104 includes: a current limiter 106 and an energy rejection unit 108.
The current limiter 106 is configured to receive the power signal P1, to limit the power signal P1 and output as a constant current power P2, to charge the super capacitor 102 through the power supply path 110. In one embodiment, the media streaming device 10 further comprises a universal serial bus port 112. The current limiter 106 actually receives the power signal P1 through the usb port 112.
In one embodiment, the media streaming device 10 is electrically coupled to the media playback device 12 through the USB port 112, and the power signal P1 is provided by the media playback device 12 through the USB port 112. However, the invention is not so limited.
Since the power supply path 110 is electrically coupled to the current limiter 106 and the media streaming module 100, the current limiter 106 also supplies power to the media streaming module 100 according to the constant current power source P2 through the power supply path 110.
The current limiter 106 is further configured to detect a voltage Vc of the first end of the super capacitor 102 to transmit a detection result RE to the disabling unit 108. The energy inhibiting unit 108 is configured to inhibit the media streaming module 100 when the voltage Vc of the first end of the super capacitor 102 is not higher than the preset voltage threshold according to the detection result RE, and enable the media streaming module 100 when the voltage Vc is higher than the voltage threshold.
In an embodiment, the media stream module 100 includes a reset unit 114, and the disable circuit 108 is configured to transmit the control signal CON to the reset unit 114 when the voltage Vc is not higher than the predetermined voltage threshold, so that the reset unit 114 resets the media stream module 100 to achieve the technical effect of power disable.
When the voltage Vc is higher than the voltage threshold, the disable circuit 108 stops transmitting the control signal CON to the reset unit 114, and the reset unit 114 does not reset the media stream module 100 any more, so that the media stream module 100 is turned on, thereby achieving the technical effect of enabling.
In one embodiment, the media stream module 100, when enabled, will initially provide the media stream MED and transmit it to the media playing device 12 for playing through, for example, but not limited to, the usb port 112.
In one embodiment, the voltage threshold may be set to a predetermined ratio of the operating voltage of the media stream module 100. For example, when the operating voltage of the media streaming module 100 is 4.8 volts, the voltage threshold may be selectively set to 4.8 volts, 4.7 volts, or 4.6 volts, as required.
It is noted that, in one embodiment, when the voltage threshold is set too high, the overall startup speed of the media streaming device 10 will be slow. When the voltage threshold is set too low, the current of the power supply cannot be charged by the super capacitor 102 and the media stream module 100 at the same time because the power supply is started too early. Therefore, in application, the voltage threshold can be adjusted according to actual conditions, so that the starting-up speed and the current load amount reach reasonable ranges.
When the media streaming device 10 is just turned on, the large capacitance of the super capacitor 102 will draw a large charging current. However, when the source of the power signal P1, such as but not limited to the aforementioned media playback apparatus 12, is unable to provide a large current, it is easy to cause an abnormal power supply. Therefore, the current limiter 106 can stably supply power to the super capacitor 102 for charging by outputting the constant current power P2.
Moreover, when the media streaming device 10 is just turned on, the constant current power supply P2 cannot supply the current required for charging the super capacitor 102 and turning on the media streaming module 100 at the same time, which may cause the media streaming module 100 to crash (crash). Therefore, the power-on abnormal condition of the media streaming module 100 can be avoided by the power-down unit 108 for powering down the media streaming module 100 when the capacity of the super capacitor 102 is not full.
After the media streaming module 100 starts to operate to provide the media streaming MED, some internal units, such as, but not limited to, a processing unit, a graphics processing unit, and a WiFi communication unit, may have a situation where the instantaneous power consumption is too high (for example, but not limited to, the power consumption exceeds 2.5 watts within 1 second), and an instantaneous large current is needed. At this time, the media stream module 100 may draw the required current from the super capacitor 102. The super capacitor 102 will provide the technical effect of stabilizing the power supply.
Therefore, in one embodiment, the media streaming device 10 can directly receive power from the media playing device 12 through the usb port 112, such as but not limited to 5 v, 500 ma, and provide the required large current through the super capacitor 102 when the instantaneous power consumption is too high, without worrying that the provided power of the media playing device 12 cannot bear the excessive instantaneous power consumption.
It should be noted that the above-mentioned architecture of the media streaming device 10 is only an example. In other embodiments, other circuit elements may be electrically coupled between the elements without affecting the technical effect of the media streaming device 10, and are not limited by the architecture shown in fig. 1. Also, the media streaming device 10 shown in fig. 1 receives power from the media playback device 12 through the usb port 112. However, in other embodiments, the media streaming device 10 may receive power from other power supplies through other power ports.
Please refer to fig. 2. Fig. 2 is a flow chart of a method 200 for media streaming device protection according to an embodiment of the invention. The media streaming device protection method 200 may be applied in the media streaming device 10 of fig. 1. The method 200 for protecting a media streaming device comprises the following steps (it should be understood that the steps mentioned in the present embodiment, except for the specific sequence, can be performed simultaneously or partially simultaneously according to the actual requirement.
In step 201, the current limiter 106 of the protection module 104 receives the power signal P1 and outputs a constant current power P2 to charge the super capacitor 102 and supply power to the media stream module 100 through the power supply path 110.
In step 202, the current limiter 106 detects the voltage Vc at the first end of the super capacitor 102.
In step 203, the current limiter 106 determines whether the voltage Vc is higher than the voltage threshold.
When the voltage Vc is not higher than the voltage threshold, in step 204, the disabling unit 108 disables the media streaming module 100.
When the voltage Vc is higher than the voltage threshold, in step 205, the enabling unit 108 enables the media stream module 100 to provide the media stream MED to the media stream module 100.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit of the present invention are intended to be included within the scope of the present invention.
