Abstract: A host device having a notice function for setting environment and a setting environment method thereof are disclosed. The host device includes a download unit which downloads and stores an application provided from a broadcasting station, a control unit which executes the application stored in the download unit and thus to change a setting environment, and a display unit which displays the setting environment changed by the control unit on a screen.

Abstract: An image processing apparatus includes a receiving unit which receives an image signal, an image processor which processes the image signal, a storage unit which stores setting information related to processing of the image signal, a controller which controls the image processor to process the image signal with reference to the setting information when an external controlling program comprised in the image signal is executed.

Abstract: A projection system has a display part and a digital light processor (DLP) optical system, the projection system including: a system storage part to store data inherent information corresponding to optical system data of the DLP optical system; a DLP storage part to store the optical system data and the data inherent information corresponding to the optical system data; and a controller to determine whether the data inherent information of the system storage part and the DLP storage part corresponds with each other, after reading out each of the data inherent information from the DLP storage part and the system storage part, in case that the optical system data are downloaded from the DLP storage part to the system storage part, and to download the optical system data if the data inherent information corresponds with each other.

Abstract: A broadcast reception device performing image/sound-related settings. The broadcast reception device includes an application part which executes an application program, a platform part which executes an Application Program Interface (API) for image-related and sound-related settings if the application part calls the image-related and sound-related setting API, and a function module part which implements a function corresponding to the API executed in the platform. If the image-related and sound-related setting API is a non-standard API, the application part directly calls the standard API requesting for a list of the non-standard API, and the platform part provides the non-standard API list to the application part. Accordingly, if the non-standard API is selected out of the list, the platform part executes the selected non-standard API.
