Problems solved by technology

[0010] 1) In this scheme, HLS and multicast transmission have no correlation on the network side, and only the terminal performs fusion, which cannot realize the adaptive characteristics of HLS on multicast
[0011] 2) Since HLS is not associated with multicast, smooth switching between HLS and multicast cannot be achieved

Abstract

The invention discloses an HLS transmitting method and system by multicast and a terminal, and relates to the field of HLS. The method comprises that an HLR server segments HLR streaming media of different code streams, and writes association between HLR segments and multicast groups into an index file; HLS segment files are downloaded from the HLR server via label information of the index file, and converted into multicast streams via a conversion gateway, and the multicast streams are sent to a terminal; and according to the index file, the terminal obtains multicast addresses, the received multicast streams are converted into the HLS segment files, and the segment files are sent to a player. Thus, HLS videos and audios can be transmitted via a multicast technology, and the cost is reduced greatly; and the adaptive HLS technology can be used effectively to adapt to different network environments, and is especially suitable for a data bearing network, in complex network condition, of a telecommunication service provider.

Description

technical field [0001] The invention relates to the field of HLS media streams, in particular to a method, system and terminal for transmitting HLS stream media through multicast. Background technique [0002] HLS (HTTP Live Streaming) is a dynamic bit rate adaptive streaming media technology proposed by Apple Inc., which is mainly used for streaming audio and video services. It includes an m3u(8) index file, TS media segment file and key encrypted string file. [0003] HLS streaming media technology occupies a mainstream position in the application of Internet video services in recent years because of its advantages such as low requirements on streaming servers and terminals, and the ability to ensure smooth playback under different networks through multiple bit rates. At present, HLS technology has been submitted to IETF as a standard draft. [0004] Multicast (Multicast) technology realizes point-to-multipoint network connection between the sender and each receiver. If...
