20090066852Methods for Reducing Channel Change Times in a Digital Video Apparatus - A digital video apparatus provides reduced channel change times. According to an exemplary embodiment, the digital video apparatus includes at least one receiver for receiving first and second video streams representing the same program, wherein the first video stream has at least one characteristic different from the second video stream; a first signal processor for processing the first video stream to generate a first processed video stream; a second signal processor for processing the second video stream to generate a second processed video stream having a delay with respect to the first processed video stream; a renderer for rendering the second processed video stream responsive to a channel change command; and a switch for switching from the second processed video stream to the first processed video stream after the renderer begins rendering the second processed video stream, and thereby causing the renderer to begin rendering the first processed video stream.03-12-2009
20090245393Method and Apparatus For Fast Channel Change For Digital Video - There are provided methods and apparatus for fast channel change for digital video. An apparatus includes at least one encoder for receiving normal video data and channel change video data and encoding the normal video data and the channel change video data in a normal video stream and a channel change video stream, respectively, using a common system clock to provide synchronization between the normal video stream and the channel change video stream. The normal video stream and the channel change video stream are encoded for transport separately at a transport level.10-01-2009
20100046634Video data loss recovery using low bit rate stream in an iptv system - A system and method for recovering from data loss are described including monitoring a first bit rate video data bit stream to determine if there is frame loss or damage, multiplexing decoding parameters of a second bit rate video data bit stream, the second bit rate video data bit stream and the first bit rate video data bit stream, if there is frame loss or damage, demultiplexing the first bit rate video data bit stream and the second bit rate video data bit stream, decoding the first bit rate video data bit stream, removing damaged frames from the first bit rate video data bit stream, decoding the second bit rate video data bit stream, up-sampling frames from said processed second bit rate video data bit stream if said processed second bit rate video data bit stream has a lower resolution than said processed first bit rate video data bit stream and merging frames from the second bit rate video data bit stream and the first bit rate video data bit stream.02-25-2010
20100064316METHOD FOR REDUCING CHANNEL CHANGE TIMES AND SYNCHRONIZING AUDIO/VIDEO CONTENT DURING CHANNEL CHANGE - A digital A/V apparatus provides reduced channel changes times and maintains synchronization between audio and video content during a channel change event. According to an exemplary embodiment, the digital A/V apparatus includes at least one signal receiver for receiving a first audio stream, a first video stream and a second video stream, wherein the first and second video streams represent the same program and the first video stream has at least one characteristic different from the second video stream; a first audio signal processor for processing the first audio stream to generate a first processed audio stream; a first video signal processor for processing the first video stream to generate a first processed video stream; a second video signal processor for processing the second video stream to generate a second processed video stream having a delay with respect to the first processed video stream; a first buffer for buffering the first processed audio stream to provide de-jittering; a renderer for rendering the first processed audio stream and the second processed video stream in response to a channel change command; a switch for switching from the second processed video stream to the first processed video stream after the renderer begins rendering the second processed video stream, and thereby causing the renderer to begin rendering the first processed video stream; and whereby synchronization between the first processed audio stream and the first processed video stream is maintained during a channel change event.03-11-2010

20100281981CHARACTERIZATION WITH PICOSECOND ULTRASONICS OF METAL PORTIONS OF SAMPLES POTENTIALLY SUBJECT TO EROSION - A method for evaluating a manufacturing process is described. The method includes generating an optical pump beam pulse and directing the optical pump beam pulse to a surface of a sample. A probe pulse is generated and directed the probe pulse to the surface of the sample. A probe pulse response signal is detected. A change in the probe pulse varying in response to the acoustic signal forms the probe pulse response signal. An evaluation of one or more manufacturing process steps used to create the sample is made based upon the probe pulse response signal. Additionally the method may be used for process control of a CMP process. Apparatus are also described.11-11-2010
