Embodiment Construction

[0034] Because the existing network bandwidth is not enough to support streaming media services that require higher transmission bandwidth, or cannot support higher bandwidth requirements required to improve the quality of streaming media services.

[0035] The basic idea of ​​the present invention is: on the basis of the realization of the existing streaming media service, the media connection that should be between the streaming media server and the master terminal that obtains the streaming media files is transmitted by means of multiple slave terminals participating in the coordinated transmission. The data packets are partially distributed to the media connection between the streaming media server and the slave terminal for transmission, and the slave terminal sends the received data packets to the master terminal through the local connection, thereby easing the connection between the streaming media server and the master terminal. The bandwidth pressure of the media conne...

Abstract

The invention discloses a coordinated transmission method for a streaming media file, a system and a device. The method, the system and the device are used for solving the problem that a present network bandwidth is insufficient to support a streaming media service with a higher demand on a transmission bandwidth. The coordinated transmission method comprises the following steps: obtaining downloading identifiers from a streaming media server by a master terminal, wherein the quantity of the downloading identifiers is as same as the quantity of terminals participating in the coordinated transmission; allocating the obtained downloading identifiers to each of the terminals participating in the coordinated transmission according to a principle of occupying different downloading identifiers by each of the terminals participating in the coordinated transmission; establishing a media downloading control linkage and a media downloading linkage by the master terminal and the streaming media server according to the allocated downloading identifiers; receiving a packet sent by the streaming media server based on the established linkage; and receiving the packet participating in the coordinated transmission sent from the terminals. According to the coordinated transmission method, a bandwidth pressure of the media linkage between the streaming media server and the master terminal is relieved and the requirement for the streaming media service with the higher demand on the transmission bandwidth is met.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular, to a cooperative transmission method for streaming media files, a terminal device, a streaming media server and a cooperative transmission system for streaming media resources. Background technique [0002] With the development of 3G mobile communication technology, mobile streaming media services including video-on-demand services and mobile TV services will be widely promoted. Streaming media service data is transmitted on the network by means of streaming transmission. Streaming media services do not need to completely download the entire streaming media file before playing, but only need to download and buffer the initial part of the streaming media file; during playback, as long as the part of the streaming media file before the current playing time has been downloaded and buffered, it is guaranteed It can be played normally, so that it can be transmi...
