  • Publication number: 20090115845
    Abstract: Certain aspects of a method and system for inverse telecine and scene change detection of progressive video may include determining a cadence, for example, 3:2 or 2:2 pulldown, and phase of received progressive input pictures. A difference between two or more consecutive received progressive input pictures may be determined. The motion compensation of a plurality of output pictures may be controlled based on the determined cadence, phase and difference between two or more consecutive received progressive input pictures. The system may be enabled to determine repeated pictures and scene changes. The motion compensation of output pictures may be stopped during detected scene changes.

  • Patent number: 7468757
    Abstract: Herein described are at least a system and a method of more effectively detecting and correcting irregularities when performing an inverse telecine deinterlacing of pull-down video. These irregularities may be caused by editing of the video, which when left undetected, may result in displaying video of unacceptable quality. In a representative embodiment, the method determines a first pixel luminance of an absent pixel using a luminance generated from one or more first present pixels, determines a second pixel luminance of the absent pixel using a luminance generated from one or more second present pixels, and determines a first luminance approximation for the absent pixel. In a representative embodiment, the system comprises a memory, a software resident in the memory, and a processor used to execute the software, such that executing the software performs the inverse telecine deinterlacing to result in an improve displayed video image quality.

  • Publication number: 20080117329
    Abstract: Herein described is at least a method and system for deinterlacing an interactive or non-interactive video. The method comprises receiving a control signal by a user that indicates whether the video is an interactive video or a non-interactive video. The method further comprises deinterlacing the video such that an amount of delay to the video is incurred through a deinterlacer, wherein the amount of delay is based on the control signal. In a representative embodiment, the system comprises one or more first inputs for providing interactive video to a deinterlacer, one or more second inputs for providing non-interactive video to the deinterlacer, and a circuitry for selecting one input of the one or more first or the one or more second inputs based on a control signal.

  • Publication number: 20080012984
    Abstract: Herein described is a method and system for generating an improved video output when deinterlacing pull-down video. The improvement results from reducing cross-chroma artifacts. In a representative embodiment, the method comprises first computing an adjusted chroma of a present pixel from a present top field or present bottom field of film sourced video as a function of an execution stage field phase. The method further comprises second computing a chroma of an absent pixel vertically adjacent to the present pixel, wherein the second computing is performed as a function of the execution stage field phase. In a representative embodiment, a deinterlacer video engine and a local storage circuitry process the 3:2 pull-down video by applying various equations for performing the first computing and the second computing. An adjusted chroma and an absent pixel chroma is computed for each present pixel at each execution stage field phase.

  • Patent number: 6696030
    Abstract: A method is provided for reducing the chemical conversion of oxidizable or disproportionable compounds contained in liquid or gaseous process media which contact carbonaceous chars. In this method the carbonaceous char contacting the oxidizable or disproportionable compounds is first treated with a non-nitrogen-containing Bronsted acid. The acid-treated char is then heated to temperatures greater than 750° C. In this manner the inherent catalytic reactivity of the carbon in the char is reduced effectively and largely irreversibly.

  • Patent number: 6514906
    Abstract: A carbonaceous char is provided having a reduced inherent carbon catalytic activity. The char is derived from one or more of the following: wood, nutshell, fruitstone, peat, lignite, sub-bituminous coal, bituminous coal, semi-anthracite coal, anthracite coal and organic polymers, and has an inherent or “MOD 12” t-¾ time equal to or greater than 125 minutes or a maximum delta T less than or equal to 20° C. The MOD 12 t-¾ time is equal to the elapsed time required for 0.250 grams of said carbonaceous char, pulverized, to decompose from ambient temperature and under adiabatic conditions three-fourths of 0.42 moles of hydrogen peroxide contained in 150 mL of an aqueous solution containing a buffer having a pH of about 12. The maximum delta T is the absolute temperature difference between ambient temperature and the maximum temperature achieved by the hydrogen peroxide decomposition wherein the carbonaceous char has been inertly calcined at temperatures above 700° C.

  • Patent number: 6310000
    Abstract: A process is provided for the manufacture of a carbonaceous char capable of catalyzing the rapid decomposition of hydrogen peroxide in aqueous solutions. This carbonaceous char is produced from a bituminous coal or a bituminous material that has been carbonized and extensively oxidized at low (less than 700° C.) temperatures. The resultant carbonized and oxidized bituminous coal or bituminous material is then contacted with a nitrogen-containing compound in combination with at least one of sucrose or fructose as the temperature of the low-temperature char is increased to greater than 700° C. This treatment results in a high-temperature char which may then be activated as desired. These activated chars show the aforementioned ability to rapidly decompose aqueous solutions of hydrogen peroxide and are also useful for the catalytic decomposition of H2S, SOx, NOx, chloramines, and/or peroxides in liquid and/or gaseous streams.
