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: 10531147Abstract: The subject system allows a source device providing a content stream over a network connection to a sink device to adaptively bypass a transcoding portion of a content processing pipeline when the original content stream, e.g. the non-transcoded content stream, can be decoded by the sink device and/or when no actions that utilize transcoding have been requested for the content stream. The source device may power down the transcoding portion of the content processing pipeline when the transcoding portion is not in use. When an action that utilizes transcoding is requested, and the transcoding portion of the pipeline is being bypassed, the source device may power on the transcoding portion and adaptively modify the pipeline to pass the content stream through the transcoding portion. The source device may provide configuration messages to the sink device when the pipeline is modified to provide information for decoding the transcoded content stream.Type: GrantFiled: August 21, 2018Date of Patent: January 7, 2020Assignee: AVAGO TECHNOLOGIES INTERNATIONAL SALES PTE. LIMITEDInventors: Steven Hartley, Fabian Alberto Russo, James F. Dougherty, Stephen Ray Palm

Patent number: 9807784Abstract: Video sub-reservation protocol in a wireless ecosystem. Appropriate access is provided to a number of wireless communication devices to ensure very high performance and a high perceptual user experience with respect to media related content communications. Access to the communication medium (e.g., air within a wireless location system) is provided to various wireless communication devices in a manner as to minimize collisions and contention. In one instance, different respective access assignment periods are sub-divided to give respective communication medium access to various devices within the system. Such sub-reservation may be adaptive in response to any of a number of considerations (e.g., traffic, device processing history, etc.). Also, such sub-reservation may provide respective time specificity at or during which certain devices may conduct communications, but may also specify any other operational parameters (e.g.Type: GrantFiled: May 28, 2015Date of Patent: October 31, 2017Assignee: AVAGO TECHNOLOGIES GENERAL IP (SINGAPORE) PTE.

Patent number: 9351010Abstract: Transcoding multiple media elements for independent wireless delivery. Respective media or multimedia elements are selectively and respectively encoded and/or transcoded. Such respective and selective processing of different media elements provides for their unbundled and independent communication to one or more other devices. In one instance, different respective overlays of a display (e.g., a computer, TV, PDA display, etc.) are respectively and selectively transcoded and/or encoded to generate different respective streams that may each be handled differently as a function of any number of parameters (e.g., media element type, content, communication channel characteristic, source proximity, priority, etc.). Different types of media elements include photo/image, video, graphics, text, audio, picture-in-picture, two-dimensional (2D), three-dimensional (3D), and/or other types of media elements as may be included within a given configuration of a display.Type: GrantFiled: November 24, 2014Date of Patent: May 24, 2016Assignee: BROADCOM CORPORATIONInventors: James F.

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: 8937956Abstract: A network device receives multiple protocol data units (PDUs), or packets, and initiates aggregation of an intended number of the packets to form a transmission block. During the aggregation process, the device receives a priority PDU, or packet, and in response to receiving the priority PDU, terminates the aggregation process, either permanently or temporarily, even though the number of packets aggregated prior to receiving the priority packet is less than the number of packets intended to be included in the transmission block. The device releases the priority packet for transmission out of turn, ahead of the already aggregated packets. The priority packet can be released individually, with the aggregation being resumed after release of the priority packet, or the priority packet can be pre-pended to the already aggregated block of packets and the entire block released with a priority assigned according to the priority of the priority packet.Type: GrantFiled: December 21, 2011Date of Patent: January 20, 2015Assignee: Broadcom CorporationInventors: Ragu (Raghunatha) Kondareddy, Yasantha N.
