Patent number: 10587954Abstract: The present disclosure is directed to systems, apparatuses, and methods for wirelessly delivering multi-channel audio over a packet based network with tight synchronization, high fidelity, and/or low delay as described above. The systems can include a source device that provides multi-channel audio to a distributor device, which wirelessly distributes the multi-channel audio over the packet based network to audio rendering devices, referred to as “sink” devices. The distributor device and the sink devices each include a playback clock that is used to read audio samples of the multi-channel audio from a local memory and drive a digital-to-analog converter (DAC) coupled to a speaker to render the audio samples.Type: GrantFiled: June 19, 2019Date of Patent: March 10, 2020Assignee: Avago Technologies International Sales Pte.

Patent number: 9071848Abstract: Sub-band video coding architecture for packet based transmission. Video processing includes converting of a frame or picture of a video signal into a number of respective sub-bands or sub-frames (e.g., such that each respective one is a respective subsampled version of an original frame or picture) and subsequent assembly thereof into a reconstructed frame or picture. The reconstructed frame or picture then undergoes video encoding to generate an output bitstream that may subsequently undergo appropriate processing (e.g., packetization, continuous time signal generation, etc.) to generate a signal for transmission via one or more communication the links. Characteristics associated with each respective sub-band or sub-frame may be similar (e.g., similar characteristics) or different (e.g., two or more sub-bands or sub-frames have different characteristics, such as different respective number of pixels, aspect ratios, etc.). Respective sub-frames may undergo video encoding and transmission.Type: GrantFiled: March 15, 2012Date of Patent: June 30, 2015Assignee: Broadcom CorporationInventors: Gianluca Filippini, James F.

Patent number: 8830300Abstract: Techniques for converting 3D images using alpha maps are described. A left-view image and a right-view image may be determined from media data received by a 3D display system. An alpha map specifying a plurality of operations for a plurality of locations that correspond to the first plurality of locations in the images may also be determined. The plurality of operations specified in the alpha map may be applied by the 3D display system to process the left-view and right-view images, and to generate, based on the left-view and right-view images, a third image in an appropriate 3D format.Type: GrantFiled: March 5, 2011Date of Patent: September 9, 2014Assignee: Dolby Laboratories Licensing CorporationInventors: Gianluca Filippini, Reinhard Steffens, James Dougherty, Thomas Zato

Patent number: 8743178Abstract: Techniques for multi-view video format control are provided. In some embodiments, a display video format supported by a display panel is determined. A video format code is extracted from a coded bitstream in which a plurality of images is encoded in two or more source video formats. The video format code identifies a source video format in which a set of images in the plurality of images is encoded. A video format filter is selected to modify the set of images encoded in the source video format to generate another set of images encoded in the display video format. The other set of images encoded in the display video format is sent to the display panel.Type: GrantFiled: January 4, 2011Date of Patent: June 3, 2014Assignee: Dolby Laboratories Licensing CorporationInventors: Gianluca Filippini, Reinhard Steffens, James Dougherty, Thomas Zato

Patent number: 8401370Abstract: Techniques for providing application tracks in a media data container are described. An application descriptor may be extracted from a coded bitstream. The coded bitstream comprises media data to be played by a media presentation system. The application descriptor identifies an application archive (i) that is retrievable by the media presentation system from one or more sources and (ii) that is required by the media presentation system at a set media time associated with the media data. While playing the media data, the media presentation system causes retrieving all of the application archive from the one or more sources before the set media time.Type: GrantFiled: March 5, 2011Date of Patent: March 19, 2013Assignee: Dolby Laboratories Licensing CorporationInventors: James Dougherty, Thomas Zato, Gianluca Filippini, Reinhard R Steffens
