Abstract

The invention provides a method and a system for embedding type linux platform media playing. The method for embedding type linux platform media playing includes steps of S01: building xml information files which include playing time stamping fields and playing content fields; and S02: building xml information files, obtaining the playing time stamping fields and the playing content fields, obtaining playing content fields corresponding to the current system time of the playing time stamping fields according to the current system time and obtaining corresponding fields for playing according to the playing content fields. The time stamping fields comprise specific initial time and ending time, the contents to be played can be defined according to the playing contents recorded by the xml files, so that specific contents can be controlled to be played within specific time periods, and the playing effects like power point (ppt) can be achieved. The time periods and the playing contents are accurately positioned, so that a large amount of redundant information cannot be caused, and a large amount of storing space is not need to be set.

Description

technical field [0001] The invention relates to a media playing method and system, in particular to an embedded linux platform media playing method and system. Background technique [0002] The Chinese invention patent application with the application number "200710043413.8" discloses a remote dynamic monitoring video animation program broadcasting system, which is based on linux and communicates with the front-end automatically developed flash player and video player through xml and http protocols Interaction, to automate the display of animations, etc. When starting up, the system will automatically play according to the preset settings. Dynamic changes can also be made to static pictures, and the system can also be controlled to change the play sequence of animations. [0003] As shown in the content disclosed in the above application documents, in order to realize teaching demonstrations or advertising screenings, the embedded linux system usually adopts a video playba...
