December 22, 2018. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent ReferencesData demultiplexer Method and apparatus for audio and video synchronizing in MPEG playback systems Decoder for audio signals of compressed and coded audiovisual streams Method and system for locating a frame position in an MPEG data stream Apparatus and method for correcting jitter in data packets Simple bus and interface system for consumer digital equipment Digital signal processor, processing method, digital signal recording/playback device and digital signal playback method Inspection lamp with thin-film dichroic filter Data encoding method and apparatus for outputting encoded data at a designated time Patent #: 6088063 InventorAssigneeApplicationNo. 217203 filed on 12/22/1998US Classes:348/512, Locking of video or audio to reference timebase375/240.25Specific decompression processExaminersPrimary: Kostak, Victor R.Attorney, Agent or FirmInternational ClassH04N 009/475Foreign Application Priority Data1997-12-29 KRAbstractAn apparatus and method for MPEG decoding are disclosed which control decoding without reference to the system time clock for a predetermined time period during a discontinuity of system time clock. Thus, an error caused by inconsistency between the system time clock and the time stamp due to delay of the video buffer is eliminated, thereby allowing normal decoding with A/V lip-synchronization.Field of SearchLocking of video or audio to reference timebaseAudio to video FLUTTER OR JITTER CORRECTION (E.G., DYNAMIC REPRODUCTION) Line, field, or frame skipping Having time code for addressing signal Comb filtering Synchronization Reference indication consists of a gap Mutual (reciprocal) synchronization Transmission time into time slots adjusted based upon propagation delay time Using synchronization information contained in a frame Adjusting for phase or jitter Including delay device Specific decompression process | |
