  • Patent number: 6329998
    Abstract: A multiple screen HDTV (High Definition television) processor includes two detectors and a background screen generator. The first detector generates an output signal when format change is detected. The second detector generates an output signal when change in the selected multiple screen is detected. Either output signals activate the background screen generator to delete residuary screen portions caused by different screen sizes and aspect ratios in a multiple screen generation system.

  • Patent number: 6175387
    Abstract: Apparatus and method for converting a video received in a digital TV to process video data with different formats using the same ports. The apparatus and method includes a process to convert the video data from one format to another format and a process to convert the sync signals of one video format to correspond to the sync signals of another video format. Thus, different videos such as NTSC or VGA signals can be interfaced using signals of a small number of ports, thereby to reducing an overall size of the necessary hardware.

  • Patent number: 6094230
    Abstract: A system and method for generating the display of multiple screen digital television includes a size controller to adjust the image size by cutting or enlarging the outer portion of the image before the image is reduced to fit the size of a selected PIP window. The size controller also adjusts the image sizes for the main display window if the input image data format does not have a standard image size.
