Abstract: Embodiments of this application disclose a converter and a transmission system that are configured to effectively ensure successful signal transmission between a network device and a terminal device. The converter is configured to connect to a first cable, the first cable is a photoelectric composite cable, and the first cable includes an optical fiber configured to transmit an optical signal with a passive optical network PON protocol format and a first transmission line configured to transmit a first power supply current. The first transmission line is connected to a conversion unit, the conversion unit is further configured to connect to a data interface, and the data interface is configured to transmit an electrical signal with a target protocol format.

Abstract: The disclosure provides a screen projection method, a screen projection apparatus and a storage medium. The method includes: determining, in response to a meeting screen projection request of a user, at least one candidate meeting reservation notification that meets a preset condition from current meeting reservation notifications of the user; obtaining and displaying meeting prompt information corresponding to each candidate meeting reservation notification; obtaining a first screen projection code corresponding to the meeting prompt information; and performing, in response to detecting a screen projection instruction of the user for a target meeting prompt information of the meeting prompt information, a screen projection connection with a screen projection device based on the first screen projection code and the target meeting prompt information.
