Method and terminal for acquiring emergency event

Abstract

The embodiment of the invention discloses a method and terminal for acquiring an emergency event. The method comprises the following steps of: monitoring an emergency broadcast linkage descriptor in a network in real time and acquiring an update mark in the emergency broadcast linkage descriptor; according to the update mark, judging whether an emergency broadcast event described by the emergency broadcast linkage descriptor can be updated; when the emergency broadcast event can be updated, acquiring and analyzing emergency event description information in the emergency broadcast linkage descriptor; and displaying the emergency event described by the emergency event description information. The invention aims to provide the method and the terminal for acquiring the emergency event, which can be used for implementing acquisition of the corresponding emergency event from an emergency broadcast server which simultaneously faces a DVB (Digital Video Broadcasting) network, a bandwidth IP (Internet Protocol) network and combination of the DVB network and the bandwidth IP network and is used for issuing the emergency event. The information sharing of cross-platform, even internetwork is realized. The hardware cost of a front end is saved. The service contents of the front end are enriched. The reference is provided for developing an NGB (Next Generation Broadcasting) service.

Description

technical field [0001] The present invention relates to the communication field, in particular to an emergency acquisition method and terminal. Background technique [0002] At present, emergencies can be broadcast and released separately for mobile multimedia broadcasting, DVB (Digital Video Broadcasting, digital video broadcasting) network or broadband IP (Internet Protocol, a protocol for interconnection between networks). As the development progresses, the applications of digital TV, IPTV (Interactive Personality TV, Interactive Internet TV), Internet TV and other terminals are becoming more and more popular. [0003] But in the prior art, there is not a kind of method that can obtain corresponding emergency events from the emergency broadcast server facing DVB network, broadband IP network and combined broadcasting of DVB network and broadband IP network simultaneously to issue emergency events, so different networks Resource sharing has not yet been realized.

[0003] But in the prior art, there is not a kind of method that can obtain corresponding emergency events from the emergency broadcast server facing DVB network, broadband IP network and combined broadcasting of DVB network and broadband IP network simultaneously to issue emergency events, so different networks Resource sharing has not yet been implemented between

When it is necessary to broadcast and release the same information in different networks at the same time, such as an emergency event, it can only be broadcast and released in different networks separately. Not only the front-end hardware costs are high, but also resources and time are wasted, which is not conducive to information sharing.
