Light source control for displaying video
A method for controlling a light source of a display is provided. Maximum frame rates for different portions of video content to be displayed on the display are determined. The light source of the display is controlled to blink according to a blinking frequency when a first portion of the video content having a first maximum frame rate is displayed. The light source of the display is controlled to not blink when a second portion of the video content having a second maximum frame rate is displayed. The first maximum frame rate exceeds a predetermined frame rate of the display. Further, the second maximum frame rate does not exceed the predetermined frame rate of the display.
1. A method for controlling a light source of a display, the method comprising:
determining maximum frame rates for different portions of video content to be displayed on the display;
controlling, by processing circuitry, the light source of the display to blink according to a blinking frequency when a first portion of the video content having a first maximum frame rate is displayed; and
controlling, by the processing circuitry, the light source of the display to not blink when a second portion of the video content having a second maximum frame rate is displayed, wherein
the first maximum frame rate exceeds a predetermined frame rate of the display, and
the second maximum frame rate does not exceed the predetermined frame rate of the display.
2. The method according to claim 1 , further comprising:
determining the blinking frequency of the light source based on the first maximum frame rate.
3. The method according to claim 1 , further comprising:
determining the blinking frequency of the light source based on metadata that is associated with the video content, the metadata indicating the first maximum frame rate.
4. The method according to claim 1 , wherein the controlling the light source of the display to blink comprises:
controlling a supply of power to the light source according to the blinking frequency.
5. The method according to claim 1 , wherein
the light source is a backlight, and
the controlling the light source of the display to blink includes controlling the backlight to blink at the blinking frequency.
6. The method according to claim 1 , further comprising:
setting the blinking frequency to the first maximum frame rate when the first portion of the video content having the first maximum frame rate is displayed.
7. The method according to claim 1 , wherein the controlling the light source of the display to not blink comprises:
setting the blinking frequency to 0 Hz.
8. The method according to claim 1 , further comprising:
receiving, by a receiver, a terrestrial broadcast signal including the video content.
9. An apparatus, comprising:
processing circuitry configured to
determine maximum frame rates for different portions of video content to be displayed on a display,
control a light source of the display to blink according to a blinking frequency when a first portion of the video content having a first maximum frame rate is displayed, and
control the light source of the display to not blink when a second portion of the video content having a second maximum frame rate is displayed, wherein
the first maximum frame rate exceeds a predetermined frame rate of the display, and
the second maximum frame rate does not exceed the predetermined frame rate of the display.
10. The apparatus according to claim 9 , wherein the processing circuitry is configured to determine the blinking frequency of the light source based on the first maximum frame rate.
11. The apparatus according to claim 9 , wherein the processing circuitry is configured to
determine the blinking frequency of the light source based on metadata that is associated with the video content, the metadata indicating the first maximum frame rate.
12. The apparatus according to claim 9 , wherein the processing circuitry is configured to
control a supply of power to the light source according to the blinking frequency.
13. The apparatus according to claim 9 , wherein
the light source is a backlight, and
the processing circuitry is configured to control the backlight to blink at the blinking frequency when the first portion of the video content having the first maximum frame rate is displayed.
14. The apparatus according to claim 9 , wherein the processing circuitry is configured to
set the blinking frequency to the first maximum frame rate when the first portion of the video content having, the first maximum frame rate is displayed.
15. The apparatus according to claim 9 , wherein the processing circuitry is configured to
set the blinking frequency to 0 Hz when the second portion of the video content having the second maximum frame rate is displayed.
16. The apparatus according to claim 9 , further comprising:
a receiver configured to receive a terrestrial broadcast signal including the video content; and
the light source.
17. A non-transitory computer-readable medium storing instructions which when executed by a computer cause the computer to perform a method for controlling a light source of a display, the method comprising:
determining maximum frame rates for different portions of video content to be displayed on the display;
controlling the light source of the display to blink according to a blinking frequency when a first portion of the video content having a first maximum frame rate is displayed; and
controlling the light source of the display to not blink when a second portion of the video content having a second maximum frame rate is displayed, wherein
the first maximum frame rate exceeds a predetermined frame rate of the display, and
the second maximum frame rate does not exceed the predetermined frame rate of the display.
