Abstract:
1. A television set embedded with a DVD player, which plays a DVD in which subtitle information and closed caption information are both recorded, the television set comprising: a display device; a first processor that generates, from a signal read from the DVD, a composite signal containing both of the subtitle information and the closed caption information; a second processor that extracts the closed caption signal from the composite signal, and generates an OSD signal from the extracted closed caption signal; a video signal processor that generates a display signal from the composite signal and outputs the display signal to the display device; and a data communication bus that connects the first processor and the second processor, wherein the first processor informs the second processor through the data communication bus whether or not a setting for displaying a subtitle based on the subtitle information is turned on, wherein the second processor turns off a setting for displaying a subtitle based on the closed caption information to prohibit outputting the OSD signal when informed by the first processor that the setting for displaying the subtitle based on the subtitle information is turned on, wherein the first processor is included in a microchip that includes a peripheral circuit that performs signal processing for the composite signal, and wherein the second processor is included in a microchip that includes a peripheral circuit that performs signal processing for the signal read from the DVD.
