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.

摘要： A method, a system and an apparatus for obtaining an address of a video transmission management server are disclosed. The method includes: sending a request for obtaining location information of the video transmission management server to a host parameter configuration server, where the video transmission management server is an ARQ server, a FCC server or a FEC server, or any combination thereof, and the host parameter configuration server is a DHCP server or a PPP server; and receiving a response returned by the host parameter configuration server, and obtaining the location information of the video transmission management server. In this way, the interaction procedure is simplified and the user experience is improved.
