    Abstract: An encoder and encoding method for inserting logos into a digital television signal. The logo insertion is performed at the front end of the encoder (e.g., prior to compression) by sharing the video capture frame buffer of the encoder, so there is no need for a separate logo inserter with a separate buffer, and encoding cost are reduced. An alpha blending function receives logo image and logo alpha map data for blending with input video data. The input video is retrieved from the frame buffer, and written back to the frame buffer after blending with the logo data. Subsequently, the frame buffer contents are provided to a pre-processing function for filtering and film mode detection. For a film mode frame, a drop field decision is provided from the pre-processing function to the frame buffer to drop the redundant field. The pre-processed video data is then provided for conventional compression processing. In an HDTV embodiment, several compressors are provided which each receive a panel of a video frame.

    Abstract: A video input signal is sampled and characterized in two different color space definitions, such as a color-difference color space and a primary-color color space. Certain values that are legal in one of the color spaces, for example the color difference space, can produce primary color amplitudes that are out of legal color gamut range. Such gamut violations are indicated according to the invention using a polar plot in which phase angle corresponds to hue as in a vectorscope. The color difference and/or primary color values in either or both color spaces are depicted as ranges of radii in the polar plot, which are compared to circular limit lines that can represent the legal gamut limits. In color difference color space, the signal excursion is plotted as a function of hue phase angle, producing radially inner and outer values in a plot. The excursion is calculated or processed as luminance plus and minus saturation as a function of hue phase angle.

    Abstract: A system for presenting a virtual advertisement or other virtual content in a sequences of frames of a video presentation utilizes data identifying a candidate region in the sequence of frames, a pixel signature for the region, the signature comprising a range of R, G, B values for pixels based on a standard deviation from an average value, and stored virtual content, such as an advertisement, to be implanted in the candidate region or regions. In operation, as frames having the candidate region are processed by an integration system, the alternative virtual content is substituted by default for the candidate region, except if a pixel value in the region falls outside the pixel signature range. The result is an ad that appears to be on a surface in the video presentation, as images that come between the ad and the viewer occlude the advertisement. Apparatus and methods for providing the video presentation and data sets for regions and advertisements are disclosed as well.

  • Patent number: 6373530
    Abstract: When logos or other imagery are to be added to compressed digital video bitstreams, certain constraints are applied to the encoder that generates the original compressed bitstream to enable a video logo processor (e.g., at a local broadcaster) to insert logo-inserted encoded data into the bitstream without placing substantial processing demands on the video logo processor. In one embodiment, areas where logos can be inserted are identified and the encoder is not allowed to use image data within those logo areas as reference data when performing motion-compensated inter-frame differencing for pixels outside of the logo areas. Preferably, the compressed data corresponding to the desired location for logo insertion are extracted from the compressed bitstream and replaced by logo-inserted encoded data. As a result, logos can be inserted into compressed digital video bitstreams without having to completely decode and re-encode the bitstreams, while maintaining the overall quality of the video display.

A picture-synthetic section synthesizes the subordinate picture data converted by the subordinate-picture-data-converting section on the main picture at the designated synthesizing positions.

  • Patent number: 6369858
    Abstract: An on-screen display system is adapted for displaying OSD information on an OSD background portion which is selectively filled with either an half tone video image or a background raster of a specific color selected by a user, or which is filled by superimposing the half tone video image and the half tone background raster selected by the user. Mixing and amplifying circuits are provided for each of three red/green/blue (R/G/B) channels. Each of the three mixing and amplifying circuits receives a video signal and an OSD signal of a respective channel, mixes the video signal and the OSD signal according to a video selection signal and an OSD selection signal, amplifies a mixed signal, and outputs an amplified image signal to a display. A selection signal generating circuit receives OSD signals for R/G/B channels, a video/OSD switching signal, a half tone signal, and OSD control signals generates and outputs the OSD selection signal and the video selection signal.

  • Patent number: 6366699
    Abstract: A scheme for detecting telop character displaying frames in video image which is capable of suppressing erroneous detection of frames without telop characters due to instability of image features is disclosed. In this scheme, each input frame constituting the video data is entered, and whether each input frame is a telop character displaying frame in which telop characters are displayed or not is judged, according to edge pairs detected from each input frame by detecting each two adjacent edge pixels for which intensity gradient directions are opposite on some scanning line used in judging an intensity gradient direction at each edge pixel and for which an intensity difference between said two adjacent edge pixels is within a prescribed range as one edge pair, edge pixels being pixels at which an intensity value locally changes by at least a prescribed amount with respect to a neighboring pixel among a plurality of pixels constituting each input frame.

  • Patent number: 6356316
    Abstract: Broadcast standard format video signals such as that adopted by the National Television Standards Committee (NTSC) or the European standard format of Phase Alternating Line (PAL) and some broadcast “compatible” video signals are used as inputs to a microkeyer to synchronize a microcomputer's display in a manner that allows full and complete merging of the two signals in the broadcast video domain by, for example, additive (mixing) or non-additive (keying) processes. The required synchronization in turn makes possible incorporation in any video space a variety of computer generated visuals such as illustrative graphics, titling and any other data displayed in the video. The merged video signal from this device may then be displayed on a television monitor, or transmitted, or received, or recorded by a video recorder or processed by a standard broadcast means for example. When applied to any common microcomputer display in its most fundamental form, no additional software is required.

  • Publication number: 20020012072
    Abstract: A video mixing apparatus carries out a chromakey process producing less degradation of picture quality by generating a key signal which separates a foreground object component from a screen component by using luminance information. In a three-dimensional color space, a smaller oval body surrounding a region where the foreground object is distributed and a larger oval body surrounding the smaller one are set. These two oval bodies and a distribution of a source video signal determine a key signal distribution. Key signal K=0 (zero) when the source video signal is inside the smaller oval body, and K=1 (one) when the signal is outside the larger oval body. 0<K<1 when the signal is between the smaller and the larger oval bodies. Based on the key signal K generated, the source video signal is mixed with the background video signal.

  • Publication number: 20010043285
    Abstract: A technique for displaying advertising messages along the border of a conventional video display without obscuring any of the conventional video display. A video signal is received from a television station, satellite, cable, or video recording device and the effective size of the received video information is reduced so that the received information occupies only a portion of a display device thereby freeing another portion for other use. A locally stored message is introduced to occupy the other portion of the display. The message may, for example comprise one or more advertising banners extending along edges of the received information display. The message provider may sell advertising space to customers and pay the owner of the establishment in which the program and advertising message are displayed a fraction of the advertising revenue. The locally stored message may be periodically updated by the message provider from a remote source by way of a modem or similar communication link.

  • Patent number: 6297852
    Abstract: A video display apparatus and method for displaying decoded video frames from an encoded video stream utilizes a display time difference determinator that detects a frame display time difference, on a per frame basis if desired, between a refresh rate based frame display time, and a video playback frame rate display time to generate frame display time difference data. This is done on a continuous basis to detect synchronization problems between video data that is to be displayed simultaneously with non-video data on a display device such as a progressive display screen. A pixel blender blends pixel data from an adjacent frame, such as an already reconstructed previous frame or next frame, to create a temporally adjusted frame based on the determined frame display time difference data.
