determining, by a project end, to-be-projected data when a screen projection function is enabled;
obtaining, by the project end, first data permission of the project end for the to-be-projected data and second data permission of a receive end for the to-be-projected data when the to-be-projected data is media data; and
projecting, by the project end, the to-be-projected data onto the receive end in a screen mirroring manner when the first data permission is higher than the second data permission; or
projecting, by the project end, the to-be-projected data onto the receive end in a digital living network alliance manner when the first data permission is lower than the second data permission.
