Patent number: 8035748Abstract: 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.Type: GrantFiled: July 12, 2006Date of Patent: October 11, 2011Assignee: Broadcom CorporationInventors: Richard Hayden Wyman, Brad A.

Patent number: 8026980Abstract: A system and method for improving decisions for 2D combing of a video. A 2D-comb is applied to a baseband video signal, thus producing a chroma component of the signal, and an associated combing error. A narrowband filter is applied to the chroma component to produce a filtered chroma component. The chroma component and the filtered chroma component are blended in proportions based on the amount of combing error to produce a new chroma component. A larger combing error induces selection or blending a larger portion of the filtered chroma component, which as a result of narrowband filtering contains less cross-chroma error. Subtracting the new chroma component from the baseband video signal produces a new luma component. The chroma component can also be filtered using a wider band filter to produce a non-complementary chroma component to be subtracted from the baseband video signal to produce the new luma component.Type: GrantFiled: October 6, 2006Date of Patent: September 27, 2011Assignee: Broadcom CorporationInventors: Shawn Val Johnson, Brad Delanghe, Brian Schoner, Darren Neuman

Patent number: 7408489Abstract: Aspects of the invention provide a method and system for a mixed analog-digital automatic gain control. The received analog signal is amplified by the analog amplifier and then converted to a digital value by an ADC. A clamp reference level of the converted signal is removed prior to applying a digital gain to a digital multiplied. Once the digital gain is applied, the clamp reference level is restored to the digital signal. A loop filter determines the system time response from the error between an amplitude parameter of the received signal and an AGC reference level. A gain separation circuit generates the system gain and separates it into a digital gain and an analog gain in a way to maximize the use of the analog amplifier. The analog gain is applied to the analog amplifier and the digital gain is applied to the digital multiplier.Type: GrantFiled: March 26, 2007Date of Patent: August 5, 2008Assignee: Broadcom CorporationInventors: Brad Delanghe, Aleksandr Movshovish

Patent number: 7405769Abstract: In a method and system for 3D comb synchronization and alignment of standard and non-standard video signals, a coarse synchronization is performed on a bottom frame, a current frame, and a top frame based on a bottom frame field count. The current frame is assigned the frame transferred immediately prior to a bottom frame whereas the top frame is assigned the frame transferred two frames. A current frame window signal and a top frame window signal may be used to lock the current frame and the top frame to a bottom frame vertical sync signal. After coarse synchronization, the video frames are finely aligned by correlating a phase difference between the subcarrier signals in each frame and modifying the phase difference until the correlation results in a specified phase locked value range. This method and system may facilitate the handling of video stream switching and non-standard data streams.Type: GrantFiled: June 24, 2004Date of Patent: July 29, 2008Assignee: Broadcom CorporationInventors: Brad Delanghe, Aleksandr Movshovich
