[0003] When file live streaming is used, the general implementation of advertisement insertion is to use the advertisement provided by the advertiser as an ordinary program. After the time to play the advertisement, the file live broadcast server will send the media information file of the program (hereinafter referred to as SDP (Session Description Protocol, session description) Protocol) to STB (Set TopBox, set-top box terminal), STB obtains the content of advertising programs according to the SDP information. Since STB needs to cache some programs to play normally, there will be a black screen time of more than 2 seconds in this way, and seamlessness cannot be achieved. Ad break

Abstract

Disclosed is a system for realizing non-slot inserting-broadcasting in web living broadcast comprising a web TV platform system, a document living broadcast server and a top box, the document living broadcast server and the top box are communicationally connected, wherein, the document living broadcast server includes: a timer for determining the read time of an inserting-broadcasting program before broadcasting the inserting-broadcasting program and determining the read time of the inserting-broadcasting program before ending the inserting-broadcasting program broadcasting. The present invention also provides a method for realizing non-slot inserting-broadcasting in web living broadcast, wherein, the method comprises following steps: determining the read time of an inserting-broadcastingprogram before broadcasting the inserting-broadcasting program and determining the read time of the inserting-broadcasting program before ending the inserting-broadcasting program broadcasting; when the read time of the inserting-broadcasting program is reached, the top box reads the content information of the inserting-broadcasted program, decodes and broadcasts it; when the read time of the living-broadcasting program is reached, the top box reads the content information of the living-broadcasted program on the paused broadcasting position, decodes and broadcasts it.
