Method and apparatus for providing additional information of video using visible light communication
First Claim
1. A method for providing additional information included in a video displayed on a display device having a plurality of light emitting diodes (LEDs) using a visible light communication (VLC) protocol, the method comprising:
- receiving a data packet including video data of the video and additional information associated with a particular object;
extracting the video data from the data packet, and decoding the video data;
extracting the additional information from the data packet, and decoding the additional information; and
generating visible light signals from the plurality of LEDs to output the video displaying the video data and the extracted additional information to at least one further device based on the VLC protocol, wherein first LEDs of the plurality of LEDs are provided within a first region of the display device corresponding to a location of a first object in the video, andthe first LEDs transmitting a first data packet of the VLC protocol, the first data packet representing the extracted additional information associated with the first object.

Abstract
A method and apparatus for providing additional information included in a video displayed on a display device using visible light communication (VLC). A data packet including video data and additional information for an object included in the video data is received. The video data is extracted from the data packet, and the video data is decoded. The additional information from the data packet is extracted, and the additional information decoded. The decoded video data is output through the display device, and at the same time, the additional information is transmitted for a particular object included in a video based on a VLC protocol using a light emitting device prepared in the display device. The additional information providing apparatus includes an image sensor module, a display module, a visible light receiving module, an additional information manager and a controller.
