发明名称 Channel changing method, apparatus, and system
摘要 Embodiments of the present disclosure provide a channel changing method, apparatus, and system. A network side device records in real time a timestamp of a media packet of a multicast media stream which enters a buffer, and a key frame which enters the buffer; when a terminal's channel changing request has been detected, obtains a first timestamp of a media packet which enters the buffer at a channel changing request moment, and a second timestamp of a media packet in which a key frame which is of the target channel and is the last to enter the buffer is located in the media packet; determines a timestamp difference between the first timestamp and the second timestamp; and transmits the timestamp difference and a burst media stream of the target channel to the terminal. In the embodiments of the present disclosure, a delay in playing the multicast media stream by the terminal is reduced.
