  • Publication number: 20040177383
    Abstract: Graphics metadata is embedded in an input video signal at a first system, to form a processed video signal which is distributed to a plurality of second systems, typically cable or broadcast systems. Each individual second system can edit the metadata and insert graphics into the video based on the edited metadata so as to form a final signal for broadcast or other distribution to viewers. Thus, each second system can provide a final signal with an appearance consistent with the brand identity of that individual second system. The metadata facilitates storage and retrieval of the video.

  • Patent number: 6778224
    Abstract: A method for placing overlay elements in images of a digital video so that desirable viewing areas of the images are not occluded by the overlay element, the method includes extracting frames from the video, each of the frames defining an image which may have one or more desirable viewing areas. For each frame, an area is selected in the image for placing an overlay element and the percentage the overlay element overlaps the desirable viewing areas is determined for the selected area. The overlay element is placed in the selected area if the percentage is below a maximum allowed predetermined percentage of overlapping. If it is not, one or more other areas in the image are selected and/or the size, shape, aspect ratio of the overlay element is changed until a position and/or size, shape, aspect ratio is found which minimizes occlusion of the desirable viewing areas in the image.

  • Patent number: 6758540
    Abstract: TVs and other consumer electronics devices like VCRs and DVD players use on-screen display of messages. For display together with MPEG encoded video signals the picture content of an OSD text or graphic is stored in a non-volatile memory in a specific format: the OSD text or graphic content is divided into macroblock units and the OSD macroblock data are stored in MPEG encoded form in the memory. The OSD macroblocks to be displayed are then handled as a slice.

  • Patent number: 6750918
    Abstract: Described is a TV system that uses a single pixmap across multiple video rasters having different raster sizes. In general, the TV system uses at least two headers to select different portions of a single pixmap to be displayed based on different raster sizes. Specifically, each of the two headers points to a single pixmap. In the TV system, the size of the central portion is fixed while the size of the sidepanel portion can be adjusted depending on the displaying mode. In response to different displaying modes, the TV system selectively invokes one of the two headers to select a respective portion to be displayed in the pixmap. By doing so, a single pixmap can be used across multiple video rasters having different raster sizes.

  • Patent number: 6690826
    Abstract: A system and method for identifying whether sample values of pixel samples in a sample region have two or fewer different sample values represented, such as in graphics data representing text images. Identification is performed by hierarchically dividing the samples of the sample region into sample pairs and comparing the sample values of a first sample pair and a second sample pair to determine if two or fewer sample values are represented by the sample values of the first and second sample pairs. Where two or fewer levels are represented by the sample values of the samples, a tally value is generated and the first and second sample values are recorded. The recorded sample values are compared to the sample values of another sample pair to determine if two or fewer values are represented therein. If so, a new tally value is generated and the sample values are recorded.
