Publication number: 20240107132Abstract: According to one or more embodiments, a playback device is provided. The device includes processing circuitry configured to receive a video stream including a plurality of video packets, where each of the plurality of video packets is associated with a respective video timestamp value. The playback device is further configured to store at least one of the plurality of video packets in a jitter buffer, and to adjust each of the respective video timestamp values by a respective delay value, where each of the respective delay values is either a dynamic delay value based on a first condition being satisfied or a fixed delay value based on a second condition being satisfied. The playback device is further configured to play the video stream according to the adjusted video timestamp values for reduced initial delay at the jitter buffer.Type: ApplicationFiled: November 30, 2023Publication date: March 28, 2024Inventors: Michael A. ARNAO, Maurice J. BUTTIMER

Publication number: 20230049433Abstract: A method, system, server and device are disclosed. According to one or more embodiments, a server is provided. A first audio track is received which includes first audio originating from a premises client at a premises location. A second audio track is received which includes second audio originating from a remote client. A first pan angle is determined for the first audio track and a second pan angle is determined for the second audio track. The second pan angle is different from the first pan angle. A stereo composite track is generated based on the first pan angle and the second pan angle, where the stereo composite track includes the first audio track and the second audio track.Type: ApplicationFiled: August 11, 2022Publication date: February 16, 2023Inventors: Michael A. ARNAO, Maurice J. BUTTIMER, Andrew P. WEIR

Patent number: 8629893Abstract: A system and method for reducing blurred video caused by intra-coded IDR-frames sent in response to when a destination endpoint in a multipoint videoconference switches to a new video source. An embodiment according to the invention comprises using inter-coded temporal predictive referencing a long term reference frame (LTRF) instead of IDR-frames in a multipoint videoconference system.Type: GrantFiled: April 2, 2008Date of Patent: January 14, 2014Assignee: Cisco Technology, Inc.Inventors: Joseph T. Friel, Maurice J. Buttimer, Alan J. MacDonald, Michael A. Arnao, Andrew P. Weir, David W. Sowa, J. William Mauchly

Patent number: 8494049Abstract: An apparatus, software encoded in tangible media, and a method at an encoder. The method includes sending compressed video data including a reference frame message to create a long term reference frame to a plurality of decoders at one or more destination points, receiving feedback from the decoders indicative of whether or not the decoders successfully received the reference frame message, and in the case that the received feedback is such that at least one of the decoders did not successfully receive the reference frame message or does not have the indicated recent frame, repeating sending a reference frame message to create the long term reference frame. Using the method can replaces I-frame error recovery with long term reference frames, even in the case where the reference frame management messages are lost to at least one decoder.Type: GrantFiled: April 18, 2007Date of Patent: July 23, 2013Assignee: Cisco Technology, Inc.Inventors: Maurice J. Buttimer, J. William Mauchly, Joseph T. Friel

Patent number: 8310595Abstract: A method, and apparatus, and logic encoded in one or more computer-readable media to carry out a method. The method is to sample analog video at a sample clock rate and at a phase selected from a set of phases based on a quality measure determined from the sampled video. The quality measure is based on statistics of pixel to pixel differences in a coordinate of the generated digital video that have a magnitude exceeding a pre-determined threshold.Type: GrantFiled: April 21, 2008Date of Patent: November 13, 2012Assignee: Cisco Technology, Inc.Inventors: Maurice J. Buttimer, Andrew P. Weir, Michael A. Arnao

Patent number: 8218831Abstract: Techniques are provided to analyze video frames of a video signal in order to distinguish regions containing a face (and body torso) from regions that contain a relatively static background. The region containing the face is referred to as a foreground region. A current video frame is divided into a plurality of elements and the foreground regions and background regions are detected. The background regions of a subsequent video frame are detected/registered using the foreground regions of the current video frame. The foreground regions of the subsequent video frame are determined using the background regions of the current video frame as a temporal reference.Type: GrantFiled: June 30, 2008Date of Patent: July 10, 2012Assignee: Cisco Technology, Inc.Inventors: Dihong Tian, Joseph T. Friel, J. William Mauchly, Maurice J. Buttimer, Wen-hsiung Chen

Patent number: 8077772Abstract: A method, an apparatus, and a method to encode a block in a picture of a time sequence of pictures such as video. The method includes selecting the mode for coding the block, one of the modes being to code the block as skipped. The method further includes limiting the number of consecutive times a particular block is coded as skipped without re-setting the quantization level to a relatively fine level of quantization and re-selecting the mode.Type: GrantFiled: November 9, 2007Date of Patent: December 13, 2011Assignee: Cisco Technology, Inc.Inventors: J. William Mauchly, Joseph T. Friel, Maurice J. Buttimer
