Patent number: 8994879Abstract: There are provided methods and apparatus for audio and video synchronization timestamp rollover correction. A synchronization apparatus includes a synchronizer for providing synchronization information for synchronizing a video stream with an audio stream during any point in a broadcast thereof irrespective of whether the video stream and the audio stream have different rollover points for their respective timestamps. The synchronization information is encoded for an out of band transmission with respect to the broadcast of the audio and video streams.Type: GrantFiled: October 10, 2006Date of Patent: March 31, 2015Assignee: Thomson LicensingInventors: John William Richardson, Jens Cahnbley

Patent number: 8994882Abstract: Systems and methods may provide for conducting a real-time perceptual quality analysis of a video, wherein the perceptual quality analysis includes at least one of a noise measurement, a contrast measurement and a sharpness measurement. One or more strength parameters of one or more post-processing modules in a video processing pipe may be set based on the perceptual quality analysis resulting in overall video processing that adapts to the changing perceptual quality of the input. In one example, the strength parameters include at least one of a contrast parameter and a de-noising parameter. The invention results in visually enhanced video at the output of the post-processing module.Type: GrantFiled: December 9, 2011Date of Patent: March 31, 2015Assignee: Intel CorporationInventors: Kalpana Seshadrinathan, Jorge E.
