  • Patent number: 8280192
    Abstract: Systems and methods are provided that facilitate grey level magnification to improve details and contrast for a dark scene of video on a digital display system. Preferably implemented over a limited pixel level range, the video enhancement process counts the number of pixels corresponding to each level within the range in a frame and then, based on the percent level distribution of the pixels, calculates the stack of percentage distribution. From the stack of percentage distribution, a transformation process is performed to reassign the pixel values over a dark level range and to expand the distribution of the pixels. The result of transformation enhances the details and contrast of the dark area significantly without affecting the bright scene. By only applying the algorithm to dark scenes, computation loads are reduced compared with some of the full picture processing methods. Lower computational loads are important to reduce motion artifacts in high speed video applications.

  • Patent number: 8213774
    Abstract: Spotlighting and other special effects are applied by processing circuitry in real time to received video streams. Effects tracking may be applied to fixed regions or moving regions or objects of interest. Viewers interact via conventional remote controls and other user interfaces to set effect parameters. Other special effects employed include zooming, masking, etc. and can be used to enhance one or more spotlight effects. Televisions, set top boxes and media players house the underlying circuitry. Effects are applied to layered and non-layered video streams to form layered and combined video stream output. Video outputs also deliver effect parameters such as region of interest location along with a video stream. Such effect parameters assist in the downstream application of dynamic effects.

  • Patent number: 8214857
    Abstract: Provided are a method, system, and article of manufacture for generating a combined video stream from multiple input video streams. A first video stream including a first product commercial generated to be played at a first playback speed and a second video stream including a second product commercial generated to be played at a second playback speed are processed. The second playback speed is faster than the first playback speed. A combined video stream is generated including a first panel in each frame to display the first video stream and a second panel in each frame to display the second video stream. When the combined video stream is played at the first playback speed the second video stream is rendered to appear at a slower speed than the second playback speed for which it was generated. When the combined video stream is played at the second playback speed the first video speed is rendered to appear at a faster speed than the first playback speed for which it was generated.

  • Patent number: 8189678
    Abstract: A video and graphics system processes video data including both analog video, e.g., NTSC/PAL/SECAM/S-video, and digital video, e.g., MPEG-2 video in SDTV or HDTV format. The video and graphics system includes a video decoder, which is capable of concurrently decoding multiple SLICEs of MPEG-2 video data. The video decoder includes multiple row decoding engines for decoding the MPEG-2 video data. Each row decoding engine concurrently decodes two or more rows of the MPEG-2 video data. The row decoding engines have a pipelined architecture for concurrently decoding multiple rows of MPEG-2 video data. The video decoder may be integrated on an integrated circuit chip with other video and graphics system components such as transport processors for receiving one or more compressed data streams and for extracting video data, and a video compositor for blending processed video data with graphics.

  • Publication number: 20120127367
    Abstract: An apparatus and method provides temporal image processing by producing, for output on a single link such as a single cable or wireless interface, packet based multi-steam information wherein one stream provides at least frame N information for temporal imaging processing and a second stream that provides frame N?1 information for the same display, such as a current frame and a previous frame or a current frame and next frame. The method and apparatus also outputs the packet based multi-stream information and sends it for the same display for use by the same display so that the receiving display may perform temporal image processing using the multi-stream multi-frame information sent with a single link.
