Abstract

The invention discloses a subtitle amplifying method based on a set top box. The method comprises a central control unit and a virtual amplifier controlling unit which is connected with the central control unit, wherein the virtual amplifier controlling unit comprises a position controlling unit, a size controlling unit, a focus controlling unit and a multiple controlling unit; a parameter definition interface unit and a virtual amplifier configuring unit are additionally arranged. The virtual amplifier controlling unit is used for creating a special display region which can be self-defined in a display picture, amplifying the selected display picture and displaying the selected display picture through the rectangular special display region. According to the subtitle amplifying method, the picture of the subtitle display region is amplified by the virtual amplifier, thereby making it easy for the old and other users with poor eyesight to see clearly the subtitle; various parameters of the virtual amplifier can be self-defined and flexibly set in accordance with subtitle positions, amplifying multiples and the like of different programs, so that the method is quite flexible and convenient to use; the amplifier can be rapidly and simply configured by the virtual amplifier configuring unit, thereby being more suitable for the old.

Description

technical field [0001] The invention relates to a subtitle amplification method based on a set-top box. Background technique [0002] Many TV programs now have subtitles, but the subtitles are generally not very large. For people with low vision, they often have to be close to see the subtitles on TV, especially the subtitles of some programs are very small. It's hard to read, but the current set-top boxes or TVs don't support the font size setting function, which is very inhumane. Aiming at this phenomenon, the present invention proposes a set-top box that supports the font size setting function, and the user can customize and enlarge the subtitle screen, making the set-top box more humanized. Contents of the invention [0003] In order to solve the problem that subtitles with too small fonts cannot be seen clearly when watching TV programs, the present invention provides a scheme capable of enlarging image subtitles. [0004] A method for enlarging subtitles based on ...
