Abstract
The invention discloses a method for displaying data service and emergent broadcast, which comprises: a terminal displays the data service, if the emergent broadcast information is received, and the emergent broadcast level of the emergent broadcast information is low, the emergent broadcast information is displayed on the browser interface of the data service. Under the condition that the data service dose not exit, the invention realizes that the emergent broadcast information is browsed through the overlapping display way under the premise that the current data service is not interrupted, thereby being more convenient for a user to browse the data service, increasing the experience of the user and improving the flexibility of processing the terminal data.
Description
Technical field
The present invention relates to filed of mobile multimedia broadcasting, relate in particular to the method and the device of a kind of video data business and urgent broadcast.
Background technology
In recent years, digital mobile multimedia broadcasting technology and standard evolution are rapid, Ou Zhou DVB-H (Digital Video Broadcast Handheld for example, the reception of digital video broadcast-handheld formula), MediaFLO (the Media Forward Link Only of the U.S., the single forward link of medium) and the CMMB (China Mobile Multimedia Broadcasting, Mobile Multimedia Broadcasting) etc. of China.Various standards provide multiple service content for the mobile multi-media broadcast terminal user, for example advertisement, weather forecast, news, sports cast, variety, multimedia broadcasting play and film etc., the user can select the service program of Mobile Multimedia Broadcasting according to the hobby of oneself.
China mobile multi-media broadcasting technology adopts time division multiplexing mode to send multimedia broadcast signal, and the duration of its broadcast channel frame is 1 second, is made up of 40 25 milliseconds of time slots, and one or more time slots can transmit the data of a multiplexed frame encapsulation.As shown in Figure 1, in the multiplexed frame structure of Mobile Multimedia Broadcasting, multiplexed frame is divided into multiplex frame head, multiplexed frame payload and fills three parts.The mode that China mobile multi-media broadcasting technology adopts control information to separate with business datum sends.As shown in Figure 2, the multiplex frame head of mobile multimedia broadcasting multiplex frame is used for the control of multiplexed frame payload data and description, and wherein the value of " urgent broadcast indication " field is used for judging whether next broadcast channel frame comprises urgent broadcast.As shown in Figure 3, when the time slot communicating control information, corresponding multiplexed frame (MF_ID=0) encapsulation control information, control information is encapsulated in the control information table, and wherein, the urgent broadcast data encapsulation is designated in the information Control table of 0 x 10 at table; As shown in Figure 4, when the time slot transmit traffic data, corresponding multiplexed frame (MF_ID ≠ 0) encapsulation business datum, encapsulate professional data multiplexing frame and comprise one or more multiplexed sub frames, each multiplexed sub frame encapsulate video section, audio section and data segment wherein one or more, wherein, data segment is used for the encapsulation of packet (XPE or XPE-FEC bag).
Data service in the Mobile Multimedia Broadcasting (stock information and info web etc. are provided) is based on the data transmission technology realization.Data transmission technology mainly is divided into stream mode and file mode, stream mode is meant that business datum transmits in the mode of Continuous Flow, the sequential requirement is arranged usually, transmit free label indication or data flow inside synchronous requirement is arranged, but require lower to the data integrality, for example, stock information, audio stream and video flowing etc.; File mode is meant that business datum transmits in the mode of discrete data file, does not have the sequential requirement usually, transmit no time tag or synchronous requirement, but to the requirement of data integrality than higher, for example, picture, webpage and plug-in unit etc.The packet of data service generally is encapsulated in the data segment of multiplexed frame.
Urgent broadcast is a kind of method from emergency to the public that utilize broadcast communication system to announce.When accidents such as natural calamity, accident disaster, public health and social safety take place, cause or may cause great casualties, property loss, environmental destruction and serious social danger, when endangering public security, urgent broadcast provides a kind of mode of announcing efficiently rapidly.Urgent broadcast is a kind of important use of Mobile Multimedia Broadcasting, has adopted the form of broadcast to realize.After terminal is received urgent broadcast, adopt corresponding exhibition method to be shown to the user according to the rank and the type of urgent broadcast.Wherein, emergency broadcast message has literal, picture and forms such as sound, video.
In the mobile multimedia broadcast system, when receiving data service,, generally be to handle like this if there is urgent broadcast to arrive: receiving emergent broadcast, withdraw from the current data business, show emergency broadcast message.Urgent broadcast be classification other, when rank is 1 or 2 grade (high-level), data service is withdrawed from employing, show the mode of emergency broadcast message, even have certain reasonability, and when the rank of urgent broadcast is 3 or 4 grades (low level), if still withdraw from data service, show emergency broadcast message, user's data service is interrupted, have tangible irrationality.
Summary of the invention
The technical problem to be solved in the present invention provides the method and the device of a kind of video data business and urgent broadcast, shows emergency broadcast message under the situation of not interrupting data service.
For solving the problems of the technologies described above, video data of the present invention method professional and urgent broadcast comprises, when the terminal video data is professional, if receive emergency broadcast message, if the urgent broadcast rank of this emergency broadcast message is a low level, then on the browser interface of data service, show emergency broadcast message.
Further, if the urgent broadcast rank of emergency broadcast message is high-level, then terminal shows this emergency broadcast message on the browser interface in data service when video data is professional.
Further, the word content of emergency broadcast message adopts transparent or semitransparent mode to show on the browser interface of data service.
Further, the picture of emergency broadcast message and audio-video frequency content show by the window on the browser interface that is superimposed upon data service.
Further, the device of a kind of video data business and urgent broadcast, comprise: upper layer application unit and emergency broadcast message display unit, when upper layer application unit video data is professional, if the emergency broadcast message display unit receives emergency broadcast message, if the urgent broadcast rank of this emergency broadcast message is a low level, then on the browser interface of data service, show emergency broadcast message.
Further, if the urgent broadcast rank of emergency broadcast message is high-level, then when video data was professional, the emergency broadcast message display unit showed this emergency broadcast message on the browser interface of data service.
Further, the emergency broadcast message display unit adopts transparent or semitransparent mode to show the word content of emergency broadcast message on the browser interface of data service.
Further, the emergency broadcast message display unit shows the picture and the audio-video frequency content of emergency broadcast message by the window on the browser interface that is superimposed upon data service.
In sum, the present invention is under the situation that does not withdraw from data service, by overlapping demonstration emergency broadcast message, be implemented under the prerequisite of not interrupting current data service, browse emergency broadcast message, be convenient to user's browse service data more, strengthened user's experience, and improved the flexibility that terminal data is handled.
