Abstract
The invention discloses a method and a system for realizing a dynamic two-dimensional subtitle through a data array, mainly relating to the making and processing of a special subtitle effect in the field of broadcast television program making and broadcasting. The method comprises the following steps of: 1) determining a subtitle window resolution; 2) establishing a system process array unit according to the subtitle window resolution, and recording unit assignment corresponding to each frame during the special effect process in the unit; 3) establishing a system special subtitle effect data array unit databank in which a frame variable is used as a key word; and 4) reading the databank sequentially in accordance with the order of frames. The system comprises a subtitle window information reading unit, a special effect data array generating unit, a special effect data array unit databank establishing unit and a frame reading unit. According to the method and the system, selections for setting the resolution are provided for a user; subtitle window files with the same size and same resolution can be set up flexibly; by establishing the special effect data array, the actual pixel attribute change condition of the subtitle window is recoded, thereby accomplishing the establishment of the corresponding databank; for the subtitle window which is set up, the assignment may not be calculated; a duty ratio optimizing method is provided; and the pixel on which the assignment is not carried out in the subtitle window can be separated from the whole databank to be assigned uniformly, and thus the assignment number of the pixels in the actual subtitle window is reduced.
Description
Technical field
The present invention relates to making of program captions and broadcast and correlative technology field, relate in particular to a kind of method and system that realize the Dynamic Two-dimensional captions through data array.
Background technology
In existing program making and broadcast and correlative technology field, in the process to the program material making, in order better literal to be showed; Need a large amount of captions to synthesize, particularly in large-scale 3D film, material are made and play, in order to obtain better effect; Usually need in captions, insert special effects, improve constantly, occur 3D effect captions stunt successively along with what stunt was required; 3D captions stunt need be calculated lot of data in implementation procedure, and will carry out great amount of calculation by the GPU of graphic display card usually, in order to obtain the picture of high-quality; To the graphic operation processing speed, call the GPU function so hardware is had higher requirement because calculating can relate to, in the prior art; Film titler in making, playing process, provide hardware and software environment preferably in 3D captions special efficacy, and handles the restriction that the material processing speed receives the GPU disposal ability; And when playing, also there is a same requirement; In 3D captions building-up process, because handled a large amount of image files, so file needs bigger memory space and spatial cache.
Particularly in captions metamorphic animation manufacturing process, because need play order according to frame, every frame picture is calculated, therefore increased amount of calculation, particularly when resolution requirement was higher, problem was particularly outstanding.
Between above situation, in realizing process of the present invention, the inventor finds to exist at least in the prior art following problem:
Be out of shape in the making, in building-up process owing to need jumbo memory space to reach the speed of service fast at the 3D captions; So having relatively high expectations to graphic display card and GPU; In carrying out simple special efficacy building-up process, caused the waste of system, simultaneously; Also there are many-sided restrictions such as the speed of service and disposal ability for playback equipment, give the making of 3D captions distortion special efficacy and use generation to come restriction.
Simultaneously; In existing captions metamorphic animation processing procedure; Amount of calculation is directly related with the resolution of caption window, in high-resolution, large-area captions image processing process, can take a large amount of system resource; And because computational speed causes the captions generated time longer, situation about can not satisfy the demand.
Summary of the invention
To deficiency of the prior art; Reach the technical problem that the present invention will solve; The present invention provides a kind of method and system through data array realization Dynamic Two-dimensional captions, is used for 3D special efficacy captions being out of shape special efficacy manufacturing process at film titler, and in special efficacy generation and the broadcast.
A kind of method through data array realization Dynamic Two-dimensional captions, said step specifically comprises: 1) confirm caption window resolution; 2) set up system handles ordered series of numbers unit according to caption window resolution, and in said unit, write down the pairing unit of every frame assignment in the special efficacy process, become the special efficacy data array; 3) be that system special efficacy data array cell data storehouse set up in keyword with the frame variable; 4) with the frame be order, the order reading database.
Preferably, concrete steps comprise in the said step 1): 11) obtain the parameters of basic dimensions of caption window, and obtain user preset resolution; 12) through the parameters of basic dimensions of said caption window, obtain ultimate resolution; 13) whether judges presets resolution greater than said ultimate resolution, if confirm that then ultimate resolution is a caption window resolution, otherwise, confirm as caption window resolution according to user preset resolution.
Preferably, said parameters of basic dimensions comprises: distortion caption window length value X
1, distortion caption window width value Y
1
Preferably, comprise at least in the said special efficacy data array: special efficacy title, frame variable information.
Preferably, also comprise in the concrete steps said step 2): 2A) duty ratio optimization;
Preferably, said duty ratio optimization concrete steps comprise: 2A1) assignment is unified in the ordered series of numbers unit that does not have attribute change in the special efficacy data array; 2A2) above-mentioned unified assignment unit is set up duty ratio separately and optimize database.
Preferably, said step 4) can also comprise: at first duty ratio is optimized database and unify assignment.
The present invention provides a kind of system through data array realization Dynamic Two-dimensional captions, and specifically comprise: the unit is set up, the frame reading unit in caption window information reading unit, special efficacy data array generation unit, special efficacy data array cell data storehouse.Said caption window information reading unit is used to obtain definite caption window resolution; Said special efficacy data array generation unit is used for setting up system handles ordered series of numbers unit according to caption window resolution; And in said unit the pairing unit of every frame assignment in the record special efficacy process; Become the special efficacy data array, it is that system special efficacy data array cell data storehouse set up in keyword that said special efficacy data array cell data storehouse sets up that the unit is used for the frame variable.
Wherein, it is order that said frame reading unit is used for the frame, the order reading database.
Above technical scheme can find out that the present invention has the following advantages:
At first, the selection that the present invention can provide the user that resolution is set to same size, same resolution caption window file, can be set more flexibly;
Secondly, the present invention is through setting up the special efficacy data array, thus the pixel property situation of change in the actual caption window of record, thus accomplish the foundation of institute's correspondence database, to the caption window that configures, can realize disregarding the arithmetic talent value.
At last, the present invention provides the duty ratio optimization method, thereby the pixel of not carrying out assignment in the caption window is therefrom separated in the overall data storehouse, unifies assignment, thereby has reduced the assignment quantity of actual caption window interior pixel.
