Streaming media transmission method, device and system, server and terminal

Abstract

The invention discloses a streaming media transmission method, device and system, a server and a terminal. The server sends attribute information of each content fragment of a video content to the terminal; the server receives a video content request message sent by the terminal, the video content request message comprising at least the following information of each content fragment to be requested: fragment identification information, priority information, and push completion time information; the server reads the corresponding content fragments according to the fragment identification information, and sends the read content fragments to the terminal according to the priority information; and in the process of sending the content fragments, when a target content fragment cannot be sent tothe terminal according to the push completion time information, the server cancels sending of the target content fragment.

Description

technical field [0001] The present invention relates to the technical field of streaming media, in particular to a panoramic video streaming media transmission method, device, system, server, and terminal. Background technique [0002] Dynamic Adaptive Streaming over HTTP (DASH, Dynamic Adaptive Streaming over HTTP) based on HyperText Transfer Protocol (HTTP, HyperText Transfer Protocol) is a dynamic adaptive streaming media transmission protocol provided by HTTP. In the DASH protocol, media content is divided into multiple segments, and the duration of each segment is generally several seconds. The terminal obtains these fragments one by one by sending HTTP requests to the server, and then decodes and plays each fragment. When the segment length is relatively small, the number of HTTP requests will be particularly large, and the transmission efficiency will be very low. For this reason, a full-duplex DASH service has appeared. The terminal can request the server to transm...

Problems solved by technology

[0005] However, when the bandwidth is limited, or when the network is congested, or the bandwidth fluctuates, the content fragments requested by the terminal may still exceed the network bandwidth, causing the playback on the user side to freeze

Although the user can send a command to cancel the transmission of certain content when a freeze is detected, generally, when network congestion occurs, two-way communication will be affected, which may cause the server to fail to receive the user's command to cancel the content transmission in time
