Abstract: A timing control management method includes receiving a real-time protocol (RTP) packet by a jitter buffer management module, generating a playout delay range according to the RTP packet, transmitting the playout delay range to a reordering timer management module, generating a timer adjustment command from the reordering timer management module to a transport layer reordering function module, and adjusting a reordering timer according to the playout delay range by the transport layer reordering function module after the timer adjustment command is received by the transport layer reordering function module.

Abstract: An electronic apparatus at least including an audio-receiving circuit is provided. The audio-receiving circuit includes an audio receiver and a processor. The audio receiver receives a sound wave from a sound source, and generates a first audio signal containing a plurality of noises to the processor. The processor performs a signal processing of time reversal to the first audio signal to restore a sound sent at an original sound source, so as to filter noises in the first audio signal and output a second audio signal.
