Abstract

Provided are a video display control apparatus and a video display control method. A video display control apparatus, including a data storage storing graphic / control integrated data including control information used to display graphic data to be combined with video data and the video data; and a controller combining the video data and the graphic data referring to the graphic / control integrated data and transmitting the combined data to more than one display device. As described above, the transmission capacity of video data, OSD data, and graphic data for a variety of display devices is reduced, thereby lowering the bus proportion. As a whole, the power consumption required by a system is reduced, thereby realizing to be suitable for a mobile device.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2004-0068478 filed in the Korean Intellectual Property Office on Aug. 30, 2004, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The invention relates to a video display control device and a video display control method.
