All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The components, relative arrangements, functions, and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.

Also, it is apparent that the dimensions of the various parts shown in the drawings are not drawn to scale in practice for ease of description.

Techniques, methods and apparatus that are known to those of ordinary skill in the relevant art have not been described in detail for the time being, but are intended to be part of the specification as appropriate.

In all examples shown and discussed herein, any particular value should be construed as exemplary only and not as a limitation. Thus, other examples of step-wise embodiments may have a different order of precedence.

FIG. 1 illustrates the steps of the technical solution of the present invention:

The viewing effect of the bullet screen is determined by the following factors:

1. the speed of the bullet screen; 2. The number and frequency of repeated barrages; 3. the density of the bullet screen;

in practice, due to the difference of the terminals, the sizes of the screens of the terminals are different; the bullet screen speed requirements required by different screen sizes are different, so that the bullet screen self-adaptive matching speed is realized by adopting the method as follows:

in practice, the repetition degree of the bullet screen is also one of the factors influencing the viewing effect of the bullet screen, and the repeated bullet screen refers to the bullet screens which are completely the same or have similar contents and meanings and simultaneously appear in the screen of a viewer; the bullet screens are often arranged in a front-back following or up-down arrangement state; the significance is similar, so that the viewer is tired of seeing for a long time and often shields the screen, and the viewing quality is reduced;

therefore, the following method is adopted to make the bullet screen self-adaptively eliminate the weight:

a bullet screen display method is characterized in that: the method comprises a bullet screen display mode, wherein repeated bullet screens are excluded according to a display area;

the method comprises the steps of playing a target video, dividing a screen into a plurality of blocks in the playing process of the target video, and automatically eliminating excessive repeated bullet screens by adjusting the same bullet screen threshold value of the blocks.

FIG. 2 is a diagram illustrating an example of screen partition in a dynamic bullet screen adaptation method according to the present invention;

FIG. 2 includes two patterns; the segmentation block pattern 1 is a quadrilateral segmentation method, a terminal screen is segmented according to the quadrilateral segmentation method to form a plurality of congruent quadrilateral blocks of X X X, and repeated barrage and similar barrage appearing in each block are rearranged;

for example: style 1 repeated bullet curtains appear in the shaded areas in the figure, the filtering threshold can be adjusted as follows:

1) repeated bullet screens appear in the shadow blocks, and all the bullet screens are deleted;

2) if repeated barrage appears in the shadow blocks, keeping the corresponding barrage in one block, and deleting the other blocks;

3) and (4) if repeated barrages appear in the N shadow blocks, keeping corresponding barrages in the D (D is less than or equal to N) blocks, and deleting the rest blocks.

Fig. 2 includes a pattern 2 of an oblique block division method, in which a terminal screen is divided into a plurality of oblique blocks according to the oblique blocks, and repeated barrages and similar barrages appearing in each oblique block are rearranged;

for example: style 2 repeated bullet curtains appear in the shaded areas in the figure, the filtering threshold can be adjusted as follows:

1) any two blocks in the shadow block or the blank block have repeated bullet screens and are completely deleted;

3) if repeated barrage appears in the blank-keeping blocks, keeping a corresponding barrage in one block, and deleting the rest blocks;

4) and D (D is less than or equal to N) blocks are reserved, and the rest blocks are deleted.

Meanwhile, the screen blocks can be in any geometric shapes and can be fully distributed on the screen.

The relative arrangement set forth in the drawings in this embodiment does not limit the scope of the invention unless specifically stated otherwise. Also, it is apparent that the dimensions of the various parts shown in the drawings are not drawn to scale in practice for ease of description.
