Abstract

The invention discloses a media playing method, equipment and a music teaching system. Wherein, the media playing device includes a receiving unit, an audio decoding unit and an audio playing unit. The receiving unit is adapted to receive audio data from the network. The audio decoding unit is adapted to perform a decoding operation on the received audio data to obtain one or more audio frames. The audio playback unit is adapted to perform a silence detection operation on each acquired audio frame to determine whether the audio frame is silence data. If the detected audio frame is silent data, the audio playback unit discards the audio frame. If the detected audio frame is not silent data, the audio playback unit stores the audio frame into the playback buffer, so as to perform a playback operation on the audio frame in the playback buffer.

Description

technical field [0001] The invention relates to the communication field, in particular to a media playing method, equipment and a music teaching system. Background technique [0002] Currently, in real-time communication solutions such as video conferencing or webcasting, a terminal collecting media data may collect media data such as video frames and audio frames, and transmit the media data to a playback device. Here, when the collection terminal encapsulates the video frame and the audio frame according to the transmission protocol, it may add the relative time stamp to the encapsulated data packet. For example, the collection terminal uses the RTP protocol to transmit audio and video data, and adds a relative time stamp to each RTP packet header. During the data sending process, the time stamp in each sent RTP data packet is increased one by one, so that it is convenient to sort the data packets at the playback end, so as to restore the original time sequence relationsh...
