Abstract

An embodiment of the invention discloses a method and a device for transferring media files. The method includes acquiring a code rate upper limit of a next program period according to transmission history of a media data network, a current program period, a starting moment of the next program period and a finishing moment of the next program period when loading of media data of the current program period is completed; selecting a program fragment of the next program period from a media server according to the code rate upper limit of the next program period; and receiving the selected program fragment of the next program period.

Description

technical field [0001] The invention relates to the field of media transmission, in particular to a media file transmission method and device. Background technique [0002] Streaming media technology is a multimedia distribution method that is different from the traditional "download first, then start playing", which can "download and play at the same time". In order to ensure timeliness, it is required to arrive at the client before the specified time, otherwise the phenomenon of media content playback interruption waiting for buffering will occur. HTTP Streaming (HTTP streaming media, hereinafter referred to as HS) is a streaming media technology in which the application layer uses the HTTP protocol and the transport layer uses the TCP protocol to manage data transmission. The HS technology does not require a dedicated streaming media distribution server, and the distribution of media content can be easily and quickly realized by using an ordinary HTTP server (hereinafter...
