Abstract

The embodiment of the invention provides a playing method and device of a telescopic video. The method comprises the following steps of: downloading a file header of a base layer file, wherein the file header of the base layer file comprises an enhancement layer file retrieval region, and the enhancement layer file retrieval region is used for marking the storage address of each-level enhancementlayer file; downloading the base layer file and downloading the enhancement layer file according to a playing condition and the enhancement layer file retrieval region, wherein the playing condition includes a terminal resolution ratio, terminal computing power and network bandwidth; and decoding and playing the downloaded base layer file and the enhancement layer file. In the playing method and device of the telescopic video, provided by the invention, the enhancement layer file retrieval region is additionally arranged in the base layer file so that the storage address of the enhancement layer file is provided to a client side, the client side can download proper enhancement layer files according to the playing condition, the client side and network resources can be saved and sufficiently utilized, and the playing quality can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for playing scalable video. Background technique [0002] At present, the video signal sent by the streaming media server to the receiver usually adopts scalable video coding. Scalable video coding encodes the video signal into the base layer and the enhancement layer. The general scalable video coding is scalable from the time domain and the space domain. , quality domain scalability, etc. to explore the scalability of video coding. The streaming media server encodes the base layer first, and then encodes each enhancement layer layer by layer with reference to the base layer. The client decodes and plays according to the acquired data of the basic layer and the corresponding enhancement layer. [0003] In the existing scalable video playback method, the streaming media server sends the scalable video to the client after receiving the request f...
