Streaming media transmission system for mobile communication equipment terminal and application method thereof

Abstract

The invention relates to the field of mobile communication equipment terminals, in particular to a streaming media transmission system for a mobile communication equipment terminal and an application method thereof. The system comprises a transfer server installed at the mobile communication equipment terminal and used for transferring the access request of the mobile communication equipment terminal, an access module and a downloading module, wherein the access module is arranged at the mobile communication equipment terminal and is used for sending the access request; the downloading moduleis arranged in the transfer server and is used for downloading streaming media; the access module is connected with the downloading module through a network; the access module is provided with a segment requesting module for sending a segment downloading request to the transfer server; and the downloading module is provided with a segment responding module which corresponds to the segment requesting module and is used for segmenting the downloaded streaming media. The invention is more suitable for the mobile communication equipment terminal to carry out streaming media transmission broadcasting and playing by optimizing the streaming media transmission mode.

Description

technical field [0001] The invention relates to the field of mobile communication equipment terminals, in particular to a streaming media transmission system for mobile communication equipment terminals and an application method thereof. Background technique [0002] At present, there are mainly two schemes for transmitting multimedia information such as audio / video on the network: downloading and streaming. Due to limited network bandwidth, when the media file is large, it will take a long time to play it using the download solution. In the streaming transmission scheme, data such as audio and video are continuously and real-time transmitted from the server to the user terminal, and the user does not have to wait until the entire file is downloaded, but only needs a few seconds or tens of seconds of start-up delay to watch. , the user experience is better. [0003] RTSP and MMS are currently widely used streaming protocols: [0004] RTSP: Real-Time Streaming Protocol (re...

AI Technical Summary

Problems solved by technology

[0010] 1) Streaming is based on various streaming protocols, and each streaming protocol corresponds to a different network port. For example, RTSP is based on port 554, and MMS is based on port 1755... If these ports are blocked by routers or firewalls, streaming format transmission is not possible;

[0011] 2) UDP-based stream transmission such as RTSP also has certain requirements on the network. For unstable network transmission such as mobile communication equipment terminals + wireless networks, data packets can easily be lost when using UDP stream transmission, resulting in picture damage

[0012] 3) Some firewalls have restrictions on the size of files transferred at one time, so that streaming media transmission will be restricted because the files transferred at one time are too large
