Abstract

The invention provides a method and a device for modifying a broadcast list. A database is visited when a broadcast control program is triggered by a modification event and power consumption is saved. The method comprises steps: a modification request of an intraday broadcast list is obtained; a broadcast control program module is called; the broadcast control program module visits a database according to the modification request, and the broadcast list requested by the modification request is queried; modification of the broadcast list queried by the broadcast control program module is carried out according to the modification request. The method calls the broadcast control program module only when there is a modification request of a broadcast list, repeated reading of broadcast lists from the database is not needed, the broadcast control program visits the database when triggered by a modification event, and power consumption is saved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for modifying a playlist. Background technique [0002] The rapid development of Internet audio and video technology will inevitably lead to higher and higher requirements for servers. The live broadcast technology is to push the video signal being played to the client through a specific method, and the client player converts the video signal into a visual and audible video. The live broadcast server is mainly designed for application requirements such as live video broadcast, streaming media service, IPTV, interactive TV, mobile TV, business TV, distance learning, B2B business communication, video to desktop transmission, VOD system, remote monitoring, and data storage. Designed media flow equipment. [0003] When a video file is broadcast, the broadcast control program in the broadcast server first reads the playlist from the database, obtains the cor...
