  • Patent number: 9602568
    Abstract: A system for adaptive audio video (AV) stream processing may include at least one processor and a switch device. The switch device may be configured to route AV traffic to the processor, and to receive AV traffic from the processor and provide the AV traffic to a client device via one or more channels. The processor may monitor a transcoder buffer depth and depths of buffers associated with channels over which the AV traffic is being transmitted. The processor may adaptively modify one or more attributes associated with the AV traffic based at least on the monitored buffer depths. For example, the processor may adaptively adjust a bit rate associated with transcoding the AV traffic based at least on the transcoder buffer depth. The processor may utilize the depths of the buffers associated with the channels to adaptively adjust the amount of AV traffic provided for transmission over the channels.

  • Patent number: 9596041
    Abstract: A communication device (e.g., a cable modem (CM)) includes a digital to analog converter (DAC) and a power amplifier (PA) that generate a signal to be transmitting via a communication interface to another communication device (e.g., cable modem termination system (CMTS)). The CM includes diagnostic analyzer that samples the signal based on a fullband sample capture corresponding to a full bandwidth and/or a subset (e.g., narrowband) sample capture to generate a fullband and/or subset signal capture (e.g., of an upstream (US) communication channel between the CM and the CMTS). The diagnostic analyzer can be configured to generate sample captures of the signal based on any desired parameter(s), condition(s), and/or trigger(s). The CM then transmits the signal to the CMTS and the fullband and/or subset signal capture to the CMTS and/or a proactive network maintenance (PNM) communication device to determine at least one characteristic associated with performance of the US communication channel.

  • Patent number: 9595985
    Abstract: Recently proposed noise-cancelling receivers report a best case trade-off between noise figure and linearity for a matched wideband receiver. These receivers are further improved using a passive front-end gain. The front-end gain reduces the power requirements of the radio frequency transconductance stage, and potentially other stages where, e.g., smaller mixer switches may be employed.

  • Publication number: 20170070743
    Abstract: A video decoder or encoder can be used to convert and process different video streams having different combinations of frame rate and Chroma fidelity. Rather than setting the maximum sample rate of the encoder based on a Luma sample rate, the encoder's throughput is set based on a maximum color sample rate. Additionally, the picture buffer size can be set based on a maximum number of color pictures. An input of the video decoder receives an input video stream having a given display resolution and encoded in a first format employing a first combination of frame rate and Chroma fidelity. Processing circuitry in the decoder converts the input video stream from the first format to an output video stream having a second format, the second format having the given display resolution and employing a second combination of frame rate and Chroma fidelity different from the first combination.

  • Patent number: 9591493
    Abstract: A wireless communication device (e.g., operative within a wireless local area network (WLAN)) coordinates with another wireless communication device to determine which communication parameter(s) to use in at least one FTM frame exchange. In an example of operation, the wireless communication device includes a communication interface and a processor such that the processor receives, via the communication interface, a fine timing measurement (FTM) request frame from the other wireless communication device. The FTM request frame specifies at least one preferred communication parameter for the at least one FTM frame exchange. The processor then determines, based on the FTM request frame, information related to the at least one preferred communication parameter. The wireless communication device generates and transmits a response to the FTM request frame to the other wireless communication device that confirms or overrides the at least one preferred communication parameter.

  • Patent number: 9590688
    Abstract: Cellular processors are cascaded to provide different configurations, which result in higher-capacity base stations, increased numbers of simultaneous users over one frequency band, and/or aggregation of several carriers while still using only one radiofrequency (RF) chipset. The processors are aligned in both time and frequency, with each processor having a data port that allows data exchange with the other processors. The data alignment and exchange allow the processors, in the aggregate, to act as a single unit, resulting in a scalable architecture that can accommodate different system configurations.

  • Patent number: 9591042
    Abstract: A mobile device of a user discovers topological information about electronic devices in a premise environment, and shares such information with a media gateway. The media gateway uses the topological information to augment content from a server, such as a web page that supports access to media content, to add graphical objects corresponding to those electronic devices in proximity to the mobile device that are capable of reproducing the streaming media content. Selection of the one of the add-on graphical objects causes delivery of the media content to the corresponding electronic device instead of the display of the mobile device. In this manner, a more natural selection mechanism than that available using conventional pull-down lists of options is provided.
