Abstract
The embodiment of the invention discloses a kind of information dynamic substitution device, comprising: acquisition module is used to the information of obtaining information; Generation module is used for generating the BMP bitmap according to the described information that described acquisition module obtains; Output module is used to export the described BMP bitmap that described generation module generates.Described information dynamic substitution device also comprises: editor module, the described BMP bitmap editor that is used for described output module is exported is to broadcasting scene.The technical scheme of the embodiment of the invention has adopted the real-time generation of database information and the mechanism of output, has reached the effect of the dynamic replacement of information.
Description
Technical field
The present invention relates to multimedia technology field, particularly relate to a kind of information dynamic substitution device.
Background technology
Along with the arrival of information age and the impact of the network media, TV station needs more novel program and faster, abundanter information to attract more spectators.The appearance of image-text information broadcasting system provides a solution more flexibly for satisfying this demand of TV station.Image-text information broadcasting system has not only enriched the program manifestation mode, brings brand-new visual experience to spectators, and abundant more information resources can also be provided simultaneously, can attract more spectators.Image-text information broadcasting system becomes several regions with screen divider, realized that full-automatic multichannel information, captions, animation, station symbol, clock, video broadcast with screen, be applicable to that finance and economics information, sport scene are live, various fields such as weather forecast, lastest news, life prompting, program guide, TV guide, advertisement broadcast, channel pad are broadcast, thematic column, market shopping.
Yet in the prior art, image-text information broadcasting system is when realizing that information is replaced, need run up to certain quantity at the information that generates, during as 10, whole informations is converted into BMP (Bitmap, bitmap), calling for image-text information broadcasting system.Such information substitute mode need consume a large amount of time, has caused the image-text information broadcasting system information that can not upgrade in time, has reduced user's experience.
Summary of the invention
The embodiment of the invention provides a kind of information dynamic substitution device, has solved the problem of image-text information broadcasting system renewal information length consuming time, has realized the dynamic replacement of information.
For achieving the above object, the embodiment of the invention proposes a kind of information dynamic substitution device, comprising:
Acquisition module is used to the information of obtaining information;
Generation module is used for generating the BMP bitmap according to the described information that described acquisition module obtains;
Output module is used to export the described BMP bitmap that described generation module generates.
Described information dynamic substitution device also comprises:
Editor module, the described BMP bitmap editor that is used for described output module is exported is to broadcasting scene.
The technical scheme of the embodiment of the invention has the following advantages, because adopted the real-time generation of database information and the mechanism of output, thereby, reached the effect of the dynamic replacement of information.
Description of drawings
Fig. 1 is the information dynamic substitution device structure chart in the embodiment of the invention;
Fig. 2 is the information dynamic replacement specific implementation flow chart in the embodiment of the invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail: as shown in Figure 1, the information dynamic substitution device structure chart in the embodiment of the invention comprises:
Information is the data message that the database in the image-text information broadcasting system generates in real time, in the process that image-text information broadcasting system broadcasts, dynamically generates.
Behind information of every generation, can immediately this information be converted into the BMP bitmap, for the use of next step.
BMP is the irrelevant image file format of a kind of and hardware device, adopts a position mapping storage format, except picture depth is optional, does not adopt other any compressions, and therefore, the shared space of BMP file is very big.The optional 1bit of the picture depth of BMP file, 4bit, 8bit and 24bit.During BMP file storage data, the scan mode of image be by from left to right, from top to bottom order.
Because the BMP file format is exchange and a kind of standard of scheming relevant data in the Windows environment, therefore the graph image software that moves in the Windows environment is all supported the BMP picture format.
After the BMP bitmap generated, image-text information broadcasting system can call this BMP bitmap at any time according to the needs of oneself, to guarantee with the fastest Velocity Updating information.
After the BMP bitmap outputs to image-text information broadcasting system, can make scene broadcast the information such as picture and text combination, motion video window and roll titles of multizone with this BMP bitmap editor to broadcasting in the scene.
As shown in Figure 2, the information dynamic substitution method flow chart in the embodiment of the invention may further comprise the steps:
Information is hard disk and the real-time data message that generates of database in the image-text information broadcasting system, in the process that image-text information broadcasting system broadcasts, dynamically generates.
Behind information of every generation, can immediately this information be converted into the BMP bitmap, for the use of next step.
BMP is the irrelevant image file format of a kind of and hardware device, adopts a position mapping storage format, except picture depth is optional, does not adopt other any compressions, and therefore, the shared space of BMP file is very big.The optional 1bit of the picture depth of BMP file, 4bit, 8bit and 24bit.During BMP file storage data, the scan mode of image be by from left to right, from top to bottom order.
After the BMP bitmap generated, image-text information broadcasting system can call this BMP bitmap at any time according to the needs of oneself, to guarantee with the fastest Velocity Updating information.
After the BMP bitmap outputs to image-text information broadcasting system, can make scene broadcast the information such as picture and text combination, motion video window and roll titles of multizone with this BMP bitmap editor to broadcasting in the scene.
The technical scheme of the embodiment of the invention has the following advantages, because adopted the real-time generation of database information and the mechanism of output, has reached the effect of the dynamic replacement of information.
Through the above description of the embodiments, those skilled in the art can be well understood to the present invention and can realize by the mode that software adds essential general hardware platform, can certainly pass through hardware, but the former is better execution mode under a lot of situation.Based on such understanding, the part that technical scheme of the present invention contributes to prior art in essence in other words can embody with the form of software product, this computer software product is stored in the storage medium, comprise that some instructions are with so that a station terminal equipment (can be mobile phone, personal computer, server, the perhaps network equipment etc.) carry out the described method of each embodiment of the present invention.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be looked protection scope of the present invention.
