Abstract
A broadcast receiving device and method are provided with a function for displaying closed caption data. The broadcast receiving device according to embodiments of the present invention includes a signal receiving part for receiving a composite video signal, a signal processing part for signal-processing the composite video signal and converting the signal into an output format signal, a noise calculating part for calculating the noise level of the composite video signal, and a caption data detecting part for detecting closed caption data from the composite video signal and if the noise level is less than a threshold level, only then providing the closed caption data to the signal processing part to be inserted in the output format signal. Accordingly, noise degradation of the image quality can be prevented.
