Traffic track-based streaming media display method, device and system

Abstract

The invention requests to protect a streaming media displaying method and system based on transportation rail. The method comprises the following steps: a left transportation trail receives a streaming media signal message sent by at least one transportation rail in communication range of other transportation rail; the left transportation rail queries all currently received streaming media signalmessages according to the first streaming media data flow ID of the to-be-displayed streaming media, and judges whether the streaming media signal message including the first streaming media data flowID is existent; and the right transportation rail for performing displaying is determined if the streaming media signal message including the first streaming media data ID is existent. The technicalproblem that the load of a roadside dispatching station achieves the bottleneck since the mutual communication of increasing rail transportation tool and the roadside dispatching station occupies a large amount of bandwidth of the roadside dispatching station can be solved, the multimedia information interaction is performed by sufficiently utilizing the communication bandwidth, the communicationfrequency of the rail transportation tool and the roadside dispatching station is reduced, and the bandwidth resource of the roadside dispatching station is saved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of intelligent transportation, in particular to a traffic track-based streaming media display method, device and system. Background technique [0002] With the development of intelligent transportation and mobile communication technology, more and more traffic tracks can be connected to the Internet, and traffic tracks can obtain the required streams from the corresponding server through the assigned roadside dispatching station according to the streaming media displayed by users. media information. The rail transit passenger information system relies on multimedia network technology, takes the computer system as the core, and uses the station hall, platform and vehicle-mounted display terminals as the media to provide information services to passengers. Under normal circumstances, the passenger information system provides multi-media information such as travel information, service...

AI Technical Summary

Problems solved by technology

However, due to limited bandwidth resources, especially streaming media are high-bandwidth services, as more and more rail vehicles communicate with roadside dispatching stations, a large amount of bandwidth resources of roadside dispatching stations will be occupied, resulting in The load of the side scheduling platform reaches the bottleneck
