Abstract
The utility model discloses a set-top box with a light sensing system, comprising a main control chip arranged in the set-top box, wherein the set-top box is internally provided with a light sensing circuit; the light sensing circuit comprises a photoelectric sensor, a signal processor and an A/D converter which are connected in sequence; the output end of the light sensing circuit is connected with the main control chip in the set-top box; the main control chip is internally provided with an audio-video player; an interface of the audio-video player is connected with a display screen and a sound box of a television; and the light sensing circuit and the main control chip are connected by an I2C protocol bus. The set-top box utilizes the light sensing circuit to detect the intensity of the ambient light, and then controls the audio-video player to automatically adjust the volume of broadcasted programs and the display brightness of an OSD menu by the main control chip according to the light intensity. The set-top box is convenient and reliable to adjust automatically and is convenient for a user to use.
Description
Technical field
The utility model relates to the set-top box technique field, relates in particular to a kind of set-top box with the light sensing system.
Background technology
Flourish along with Digital Television, set-top box as the digital TV terminal representative has more and more entered people's family, when the user passes through the set-top box TV reception, the display brightness adjusting of the volume of broadcast program and OSD (on-screen display screen menu type regulative mode) menu is operated set box remote control by set-top box remote controller by the user and is regulated, this by the manual adjustment broadcast program volume and the mode of the display brightness of OSD menu operate cumbersome, be difficult to regulate for being unfamiliar with the people who regulates menu operation put in place, regulating not in placely will influence the user and watch broadcast program.
Summary of the invention
The utility model purpose provides the set-top box of band light sensing system of regulating the display brightness of the volume of broadcast program and OSD menu according to light luminance automatically.
The utility model adopts following scheme to realize: the set-top box of band light sensing system comprises the main control chip that is arranged in the set-top box, be provided with photosensitive circuit in the wherein said set-top box, photosensitive circuit comprises photoelectric sensor, signal processor and the A/D converter that connects in regular turn, the output of photosensitive circuit links to each other with main control chip in the set-top box, be provided with audio/video player in the main control chip, the audio/video player interface connects television display screen and audio amplifier.
Link to each other by the I2C protocol bus between described photosensitive circuit and the main control chip.
Adopt said structure, photoelectric sensor receives extraneous light, and the signal of telecommunication of generation converts digital signal to through A/D converter after signal processor processes, main control chip obtains the digital signal data that photosensitive circuit detects in real time by the I2C bus, and data are calculated and judged; When surrounding environment bright and clear, main control chip control audio/video player reduces and outputs on the television display screen the display brightness of OSD menu is corresponding, and when the light of surrounding environment changes dark gradually, with the corresponding raising output of the display brightness of OSD menu, make the display brightness of OSD menu be fit to the human eye demand; It is night when when the light luminance of surrounding environment is lower than set point, just judging broadcast program, night, environment needed quiet relatively, main control chip control audio/video player is corresponding the turning down of volume of audio amplifier output, replys the output normal quantity during surrounding environment bright and clear again.
The beneficial effects of the utility model are: utilize photosensitive circuit to detect the light power of surrounding environment, automatically regulate the volume of broadcast program and the display brightness of OSD menu by main control chip according to the strong and weak control of light audio/video player again, automatically easy to adjust reliable, be user-friendly to.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is further elaborated: Fig. 1 is the structural representation of the utility model set-top box.
Embodiment
As shown in Figure 1, the utility model comprises the main control chip 11 that is arranged in the set-top box 1, be provided with photosensitive circuit 12 in the wherein said set-top box 1, photosensitive circuit 12 comprises photoelectric sensor 121, signal processor 122 and the A/D converter 123 that connects in regular turn, the output of photosensitive circuit 12 links to each other with main control chip 1 in the set-top box 1, be provided with audio/video player 111 in the main control chip 11, audio/video player 111 connects television display screen 2 and audio amplifier 3.
Link to each other by the I2C protocol bus between described photosensitive circuit 12 and the main control chip 11.
