Since the development of the High Definition Multimedia Interface (HDMI) connector, because of its ability to output image signals and audio signals at the same time, the traditional electronic device needs to separate the connection method of the image transmission line and the audio transmission line. It has been improved. Therefore, it is rapidly popularized in the electronic device market.

However, the existing HDMI connector can only output 100mA-150mA/5V power through its power pin, that is, about 0.5W power, which cannot directly provide enough power to the electronic device connected through the HDMI connector. Therefore, various multimedia devices, such as digital TV sticks or mini cloud (TV dongle), etc., in addition to HDMI male/female connectors to transmit multimedia signals, also need to have power interface (DC jack), universal serial bus (Universal Serial Bus, USB), Mini Universal Serial Bus (mini USB) or Micro Universal Serial Bus (micro USB) and other connection ports to connect to an external power source to obtain the power required for operation. In this way, the electronic device can operate normally.

It is mainly connected to the HDMI connector on the display to connect The multimedia data (image data and sound data) generated by the operation is transmitted to the display for playback.

However, after statistics, it is found that the Mini Cloud needs to receive 700mA ~ 1A/5V, that is, about 5W of power to operate stably. Therefore, under the existing hardware architecture, it cannot receive enough power through the HDMI connector on the display. Therefore, the existing mini-cloud must be connected to and receive external power through other connection ports in order to obtain the power required for operation. As a result, other connection ports must be configured on the mini-cloud, resulting in an increase in cost. In addition, the user must also connect another power cord when using it, which not only causes inconvenience, but also has aesthetic problems.
