Abstract: Live broadcast interaction method, apparatus, device, and storage medium are provided. The method is applied in a live broadcast cooperative server connected to multiple live broadcast ends and multiple live broadcast service providers, and includes: receiving a live broadcast request sent by a first live broadcast end; providing a list of one or more connectable second live broadcast ends to the first live broadcast end; receiving a confirmation result from the first live broadcast end or a second live broadcast end; receiving original live broadcast data of the first live broadcast end and at least one second live broadcast end according to the confirmation result; processing the original live broadcast data to generate final live broadcast data; and sending the final live broadcast data to one or more live broadcast service providers. A connection across live broadcast service providers can be realized, and the scalability of live broadcast is improved.

Abstract: This invention provides a switching power supply controlling circuit, the switching power supply comprises an upper transistor and a lower transistor, the switching power supply controlling circuit comprises a boost circuit, an input terminal of the boost circuit is connected to an input terminal of the switching power supply, the boost circuit output a first voltage to control a working state of the boost circuit, driving the upper transistor to be in an on state. The switching power supply controlling circuit adopts a boost circuit to provide a driving power for the upper transistor, and there is no need to set a bootstrap pin or a bootstrap capacitor.
