Title:
METHOD AND SYSTEM FOR EMERGENCY BROADCASTING TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2010/034180
Kind Code:
A1
Abstract:
The present invention discloses a method and system for emergency broadcasting transmission. When the front end system encapsulates an emergency broadcasting message, the level information of the emergency broadcasting message is encapsulated in the frame headers of all multiplex frames or in the frame headers of all multiplex sub-frames contained in the broadcasting channel frame where the emergency broadcasting message lies. At terminal, the level information of the emergency broadcasting message can be obtained only by parsing the frame header of a multiplex frame or the frame header of a multiplex sub-frame. Whether the emergency broadcasting message should be received according to the level information is judged, thus corresponding processing is performed. The present invention provides an effective solution for the contradiction between terminal service processing and emergency broadcasting processing under the condition of limited information processing ability of TV receiving chip at present.
