Abstract: This application provides example encoding methods and example encoders. One example method includes performing bit truncation on a to-be-encoded block when a bit rate control condition is satisfied. A first cost value corresponding to the bit truncation can then be calculated. The to-be-encoded block can then be predicted to determine a prediction residual of the to-be-encoded block when the bit rate control condition is satisfied. A second cost value corresponding to the prediction can then be calculated based on the prediction residual. The first cost value can then be compared with the second cost value to determine an encoded bit.

Abstract: Embodiments of the present invention disclose a method. The method includes determining, by an OLT, that an ONU goes offline, and sending to the ONU corresponding to an ONU identifier, a detection message that carries the ONU identifier, where the ONU identifier is an ONU identifier that is occupied before the ONU goes offline and that is not reassigned, and the detection message is used to instruct the ONU corresponding to the ONU identifier to report an identification code. The method also includes receiving, a response message, where the response message carries the identification code of the ONU that sends the response message. The method also includes and determining that the ONU corresponding to the identification code carried in the response message is a rogue ONU.
