Description
Technical Field
The invention belongs to the field of intelligent equipment, relates to an internet television set top box, and particularly relates to a method and a device for presenting a background in real time based on a program poster and a television set top box.
Background
When people watch television program contents, a content provider elaborately creates poster introduction pictures in order to attract the attention of users, and the tone, composition, title and font of the poster introduction pictures are elaborately prepared by designers. When the poster picture is displayed on a television end, the poster picture is found to be matched with a background of a corresponding style or color so as to present the best visual effect.
In general, a designer prepares a fixed background, which is generally implemented as a solid color (black, blue is common), so that the scheme is relatively dull and tedious in practical experience. And another improved scheme is that a designer prepares a group of fixed backgrounds which are divided into a plurality of color systems and hues, and the fixed backgrounds are randomly matched with a specific program by a program, and the experience is that if a background picture is similar to the color system of a program poster and the hues are matched, a user can accept the background picture, but the situation that the color system and the hues are in conflict is very likely to occur, and the effect is poor.
An improved approach is to manually configure the corresponding background picture by the operator when the program is on line, which can solve the above-mentioned problems, but the adjustment is very troublesome, and the cost of manual operation is conceivable.

Further, the set proportion is 1/20-1/5 of the original size of the poster image.
Further, the set scale is 1/10 of the original size of the poster image.
Further, in the blurring unit, a Fast Blur algorithm is adopted to perform blurring processing on the first bitmap.
The invention also provides a television set-top box which comprises the device for presenting the background in real time based on the program poster.
Compared with the prior art, the invention has the following beneficial effects:
1. the invention obtains the matched background in real time according to the poster image of the current program, thereby effectively improving the visual experience effect of the user.
2. The invention has high real-time performance, does not need manual configuration, is convenient to switch and effectively reduces the operation cost.

FIG. 1 is a schematic flow chart of the present invention.
Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
Example 1
As shown in fig. 1, the present embodiment provides a method for presenting a background in real time based on a program poster, the method including the steps of:
and step S1, obtaining the poster image of the current program, and reducing the poster image according to a set scale to obtain a first bitmap.
The set ratio can be 1/20-1/5 of the original size of the poster image. In this embodiment, 1/10 scaled to the original size of the poster image is set.
The bitmap is formed through reduction processing, excessive memory consumption is avoided, the rendering speed is increased, and the effect of rendering the background when the poster image is loaded is achieved.
And step S2, performing fuzzy processing on the first bitmap to form a second bitmap.
In this embodiment, the Fast Blur algorithm is used to perform the blurring process on the first bitmap. The Fast Blur algorithm is a Fast modulus processing algorithm and can quickly realize the fuzzy effect of the ground glass.
And step S3, obtaining display size information, and stretching the second bitmap based on the display size information to obtain a third bitmap, wherein the third bitmap is just equal to the display screen in size.
And step S4, rendering and displaying the third bitmap as the current background.
By the method, when a certain program is selected, the background picture loading display with matched colors can be quickly obtained according to the color configuration of the program poster, and the video experience effect of a user is improved.
Example 2
The embodiment provides a device based on show poster presents background in real time, includes:
the image preprocessing unit is used for acquiring a poster image of a current program, and reducing the poster image according to a set proportion to acquire a first bitmap;
the fuzzy processing unit is used for carrying out fuzzy processing on the first bitmap to form a second bitmap;
