Controlling brightness of light sources used for data transmission

摘要

In a first embodiment of the present invention, a method is provided comprising: receiving a selection of a desired brightness level of a light source; receiving a piece of data to be transmitted via visible light communication using the light source; selecting a duty cycle, described by an encoding scheme, based on the desired brightness level; encoding the data using the encoding scheme, wherein the encoding includes identifying a code corresponding to both the piece of data and the selected duty cycle; and transmitting the identified code via visible light communication using the light source.

1. A method comprising:
receiving a selection of a desired brightness level of a light source; receiving a piece of data to be transmitted via visible light communication using the light source; selecting a duty cycle, described by an encoding scheme, based on identifying a duty cycle that is closest to the desired brightness level in reference to multiple cycles described by the encoding scheme, wherein selecting the duty cycle further comprises selecting a first duty cycle and subsequently selecting a second duty cycle for a subsequent piece of data; encoding the data using the encoding scheme, wherein the encoding includes identifying a code corresponding to both the piece of data and the selected duty cycle; and transmitting the identified code via visible light communication using the light source, wherein the selected duty cycle comprises an overall duty cycle across multiple pieces of data equivalent to the desired brightness level.
