Patent number: 10075726Abstract: Video decoding device is disclosed. The video decoding device comprises a demultiplexer, a first decoder and a controller. The demultiplexer receives a Transport Stream to recover video Packetized Elementary Stream (PES) to determine a presentation time stamp (PTS) and a decoding time stamp (DTS) in a PES header of the PES. The first decoder retrieves a video frame from the video PES to determine temporal reference of the video frame. The controller receives the PTS, the DTS, and the temporal reference to determine whether there is a missing video frame.Type: GrantFiled: January 8, 2016Date of Patent: September 11, 2018Assignee: MEDIATEK INC.Inventors: Ying-Jui Chen, Chung-Bin Wu, Ya-Ting Chuang

Patent number: 8811483Abstract: A video processing method includes decoding a bitstream that includes a plurality of groups of pictures and each group of pictures comprises a frame sequence, determining whether a current frame of a current group of pictures to be displayed has macroblocks with forward reference to a previous frame of a previous group of pictures, wherein the current group of pictures is subsequent to the previous group of pictures, and displaying the current frame of the current group of pictures when the current frame has no macroblock with forward reference to the previous frame of the previous group of pictures. The previous frame of the previous group of pictures is determined to be referenced by the current frame of the current group of pictures according to information specified from the encoding of the current frame.Type: GrantFiled: February 19, 2013Date of Patent: August 19, 2014Assignee: MediaTek Inc.Inventors: Wei-Jen Chen, Chung-Bin Wu

Patent number: 8401077Abstract: A video processing apparatus includes a decoder, a controller and a display device. The decoder decodes a bitstream, wherein the bitstream includes a plurality of groups of pictures and each group of pictures includes a frame sequence. The controller is coupled to the decoder to determine whether a current frame of a current group of pictures to be displayed has macroblocks with forward reference to a previous frame of a previous group of pictures, wherein the current group of pictures is subsequent to the previous group of pictures. The display device is coupled to the controller to display the current frame of the current group of pictures when the current frame has no macroblock with forward reference to the previous frame of the previous group of pictures.Type: GrantFiled: September 21, 2009Date of Patent: March 19, 2013Assignee: Mediatek Inc.Inventors: Wei-Jen Chen, Chung-Bin Wu

Publication number: 20100195742Abstract: An embodiment of error concealment method for a bitstream is provided. The method first detects an error in a current frame of the bitstream, and when the error is detected, an error concealment procedure is performed on the current frame, starting from a first macroblock thereof preceding a second macroblock associated with the detected error.Type: ApplicationFiled: February 2, 2009Publication date: August 5, 2010Applicant: MEDIATEK INC.Inventor: Chung-Bin Wu

Publication number: 20100158130Abstract: Video decoding methods are disclosed. The video decoding method comprises providing a historical syntax element of a previous video frame, receiving a current video frame to determine a current syntax element therein, determining whether a high-level syntax error is present in the current syntax element, wherein upon detection of the high-level syntax error, determining a replacement syntax element according to the historical syntax element to replace the current syntax element, decoding the replaced current video frame to detect whether there is a missing video frame or undecodable video frame, and upon detection of the missing video frame or undecodable video frame, generating a replacement video frame to substitute for the missing or the undecodable video frame.Type: ApplicationFiled: December 22, 2008Publication date: June 24, 2010Applicant: MEDIATEK INC.Inventors: Ying-Jui Chen, Chung-Bin Wu, Ya-Ting Chuang
