IMAGE SIGNAL TRANSMITTING DEVICE, IMAGE SIGNAL TRANSMITTING METHOD THEREOF, IMAGE SIGNAL RECEIVING DEVICE, AND IMAGE SIGNAL RECEIVING METHOD THEREOF

摘要

An image signal transmitting device is disclosed. The image signal transmitting device for transmitting additional information through an image signal composed of an active section in which pixel data is transmitted and a blank section in which the pixel data is not transmitted, includes a packer which receives the image signal and the additional information, inserts a signal indicating a bit value change into the image signal if a bit value with regard to the additional information is changed, adjusts the blank section according to the insertion of the signal indicating the bit value change, and outputs the image signal whose blank section is adjusted, and an encoding unit which encodes the image signal whose black section is adjusted. Accordingly, the present invention can avoid additional bandwidth consumption.;COPYRIGHT KIPO 2017
