Description

  The present invention relates to an information processing apparatus, an illumination control processing method, and an illumination control system, and is suitable for application to, for example, a television receiver capable of receiving terrestrial digital television broadcasts.

  Conventionally, in a television receiver capable of receiving terrestrial digital television broadcasts (hereinafter referred to as a terrestrial digital television receiver), a program to be selected from a terrestrial digital television broadcast wave received via an antenna is selected. A transport stream is obtained by extracting and decoding the data.

  In the digital terrestrial television receiver, the transport stream is subjected to descrambling processing, filtering processing, and the like, and then separated into program video, program audio, and data broadcast information, and the program video is displayed on an LCD (Liquid Crystal Display). ) And the like, and the program audio is output from the speaker.

On the other hand, according to the comparison result between the measurement result of the brightness component of ambient light incident on the periphery of the display screen and the brightness component of sunlight incident on the user's field of view, There is a display screen adjustment device that performs brightness adjustment (see, for example, Patent Document 1).
JP 2007-286170 A

  By the way, in the terrestrial digital television receiver, although it is possible to allow the user to view program videos of various broadcast contents such as animation, movies, variety, sports, etc., depending on the viewing environment, the physical condition of the user viewing the program video Some cases have been reported.

  For example, when a user is watching an animation in a dark room, there is a report that the user feels bad if he / she visually receives a severe color change or luminance change due to a flashing color or flash scene. . For this reason, recently, a telop that urges attention to brighten the room for viewing is overlaid on the program video.

  However, the above-described display screen adjustment device also adjusts the brightness of the display image, and does not change the viewing environment such as the brightness of the room, so that the effect is insufficient. there were.

  The present invention has been made in consideration of the above points, and intends to propose an information processing apparatus, a lighting control processing method, and a lighting control system that can always provide a more comfortable viewing environment for the user.

  In order to solve such a problem, in the information processing apparatus and the lighting control method of the present invention, the content of the video content is shown for a lighting fixture that can adjust the illuminance of the light source so that the brightness corresponds to the content of the video content. By acquiring the program information and transmitting the program information to the lighting fixture, the illuminance of the light source is adjusted with respect to the lighting fixture so that the brightness corresponds to the content of the video content indicated by the program information.

  Thereby, since the illumination intensity of a light source can be adjusted to the brightness according to the content of the video content, it is possible to always provide a more comfortable viewing environment for the user.

  In the lighting control system of the present invention, an information processing apparatus having an acquisition unit that acquires program information indicating the content of video content, a transmission unit that transmits program information, a reception unit that receives program information, and program information And a lighting fixture having illuminance adjusting means for adjusting the illuminance of the light source so as to have brightness corresponding to the content of the displayed video content.

  Thereby, since the illumination intensity of a light source can be adjusted to the brightness according to the content of the video content, it is possible to always provide a more comfortable viewing environment for the user.

  According to the present invention, since the illuminance of the light source can be adjusted to the brightness according to the content of the video content, the information processing apparatus, the illumination control processing method, and the information processing apparatus that can always provide a more comfortable viewing environment for the user An illumination control system can be realized.

3. Other embodiments

<1. First Embodiment>
[1-1. Configuration of lighting control system]
In FIG. 1, reference numeral 1 denotes an overall illumination control system according to the first embodiment of the present invention, which is composed of a terrestrial digital television receiver 2 and a luminaire 3.

  The terrestrial digital television receiver 2 is configured such that a control unit 20 having a CPU (Central Processing Unit) configuration performs overall control, and various types received from a remote controller (not shown) (hereinafter referred to as a remote controller). A television display process corresponding to the command is executed.

  In practice, the terrestrial digital television receiver 2 receives the broadcast wave S1 of the terrestrial digital television broadcast via the antenna 10 and sends it to the digital tuner 11.

  The digital tuner 11 selects a modulated signal having a predetermined frequency from the broadcast wave S1 supplied via the antenna 10 in accordance with a command from the control unit 20, and performs predetermined processing such as demodulation processing and error correction processing on the modulated signal. By performing signal processing, the transport stream TS1 is restored and sent to the demultiplexer 12.

  The demultiplexer 12 performs filtering based on the value of PID (Packet IDentification) stored in the header portion of the transport stream TS1, thereby obtaining the video stream VS1, the audio stream AS1, and the additional data ES1 for data broadcasting. This is taken out and sent to the decoder 13.

  The decoder 13 obtains the video signal VD1, the audio signal AD1, and the additional information ED1 by performing decoding processing on the video stream VS1, the audio stream AS1, and the additional data ES1, respectively.

  The decoder 13 sends the video signal VD1 to the video processing unit 16, sends the audio signal AD1 to the audio processing unit 14, and sends the additional information ED1 to the broadcast content determination unit 18.

  The audio processing unit 14 performs predetermined audio processing or the like on the audio signal AD1 supplied from the decoder 13, and supplies the audio signal ADS1 obtained as a result to the speaker 15, so that the audio corresponding to the audio signal ADS1 is obtained. Is output to a speaker.

  The video processing unit 16 performs predetermined image processing such as noise removal processing, resolution conversion processing, and frame interpolation processing on the video signal VD1 supplied from the decoder 13, and outputs the resulting video signal VDS1 to the LCD 17 Thus, a program video corresponding to the video signal VDS1 is displayed on the LCD 17.

  The broadcast content discriminating unit 18 analyzes the additional information ED1 to discriminate whether the broadcast content of the program video displayed on the LCD 17 belongs to, for example, “Cinema”, “Sports”, “Drama”, etc. Then, the program information JD as the determination result is sent to the control unit 20.
