Problems solved by technology

[0005] The above-mentioned systems based on multimedia computer network technology currently have a common problem that each system is independent and lacks unified centralized control. Not only are the buses and subways in the same city completely independent, but even different lines of the subway have their own Independent publishing centers have various formats of operating information, and there is almost no information exchange with each other, and they are even disconnected on the physical network
Moreover, there is no program playing method based on centralized control in the prior art

Abstract

The invention discloses a program-playing method. The method comprises the following steps: acquiring a to-be-played program and adding the to-be-played program to a to-be-played program queue; playing the program content of the to-be-played program queue; and selecting programs from a reserve program list and adding the programs to the to-be-played program queue if the to-be-played program queue is null. By applying the method, systems can automatically play the programs under centralized control. The embodiment of the invention also provides a media player.

Description

technical field [0001] The invention relates to a passenger information system (PIS, Passenger Information System), in particular to a method for playing programs and a media player in the passenger information system. Background technique [0002] Along with the rapid economic development, the number of public transportation such as buses, subways, trains, airplanes, and ships is also increasing rapidly. Faced with an increasingly complex public transportation system, on the one hand, operators need to automate and computerize internal management, and on the other hand, passengers also need to obtain timely operational information and guidance services in a fast and intuitive way. [0003] There are many types of systems currently used to provide information services to passengers, mainly radio, light emitting diode (LED), digital video disc (DVD), teletext. Among them, broadcasting has the widest range of applications, the earliest use time, and is instant and convenient,...
