Abstract

The invention discloses a rail transit information live broadcast system and method. The system comprises a video server group, a switch, a signal allocator and a passenger information system workstation. The video server group communicates with the passenger information system workstation through the switch and is used for obtaining an audio / video file and a playing plan sent by the passenger information system workstation and storing the audio / video file and the playing plan. The signal allocator is connected with the video server group and is used for receiving external playing signals andallocating the received external playing signals to the video server group. The video server group plays the audio / video file or the external playing signals according to the stored playing plan. Thelive broadcast system is simple in structure, is easy to install and deploy, can be linked with a passenger information system, is simple to maintain and operate and is convenient for expansion.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of rail transit, and in particular to a system and method for live broadcasting of rail transit information. Background technique [0002] The urban rail transit passenger information system is a service system that provides passengers with various information in the subway. The system needs to play specified video files and rebroadcast digital TV signals, and needs to push various videos to passengers. [0003] The structure of a traditional subway live broadcast system can include video servers, high-definition encoders, standard-definition encoders, up-down converters, and video matrices. However, there are a large number of these devices, which require professional installation and deployment. Moreover, every additional output requires additional hardware equipment, such as adding HD / SD encoders, which makes expansion difficult. Contents of the invention [0004] Embodiments...
