Patent ID: 8731406

Claim:
For use in a visible light communication (VLC) network, a method for generating high resolution frames for dimming support, the method comprising: receiving a required visibility for the high resolution frames; generating a sequence of patterns in a physical (PHY) layer of a communications device that meets the required visibility, the sequence comprising a first selected quantity of first low resolution frames selected from a set of low resolution frames corresponding to visibility patterns at a first resolution combined with a second selected quantity of second low resolution frames selected from the set, the first low resolution frames comprising a first pattern of a plurality of bits representing a corresponding positive amount of light at a light source and the second low resolution frames comprising a second pattern different than the first pattern of a plurality of bits representing a corresponding positive amount of light at the light source, wherein the first selected quantity of first low resolution frames in combination with the second selected quantity of second low resolution frames satisfies the required visibility; and transmitting the sequence to achieve the required high resolution frames.
