摘要： There is provided a mechanism for providing Adaptive Bit Rate adjustments of media streams like video for live Over the Top distribution without the need to monitor buffer fill levels, which is advantageous for live video distribution over IP networks. An embodiment of the invention is based on monitoring change in the received bitrate level at a client device, and providing a predicted future bandwidth characteristics of the network based on the change. By monitoring the received bitrate and its rate of change over time, a prediction of (near future) available bandwidth in the network is advantageously provided. A drastic drop of the received bitrate may for instance indicate that the available bandwidth will become too low to sustain a currently received media stream, and the system can accordingly initiate a decision to request a lower video quality.

摘要： This disclosure provides systems, methods and apparatuses for selectively acquiring communication frames from a transmitting device capable of formatting the communication frames in accordance with a plurality of PHY formats. In some implementations, a STA may filter or discard duplicate frames received from an AP based, at least in part, on a preference of the STA for one of the plurality of PHY formats. The filtering may be performed at the PHY, without forwarding received communication frames to the media access control layer (MAC) for further processing. In some other implementations, an AP may refrain from sending duplicate frames to a STA based, at least in part, on a preferred frame format of the STA. Still further, in some implementations, the STA may dynamically adjust or update its preferred frame format based on changes in the distance, or channel conditions, between the STA and the AP.

摘要： Certain aspects of the present disclosure relate to methods and apparatus for adjusting flow rate of transmissions received at a device. A user equipment (UE) determines, in response to detecting a trigger condition, a proposal to adjust feedback provided to a base station (BS) in order to adjust a flow rate of transmissions received at the UE from the BS. The UE adjusts the feedback based on the proposal and at least one additional condition and transmits the adjusted feedback to the BS.

摘要： Light-weight, configurable error detection in a satellite communication system that detects invalid SerDes lanes via hash codes appended to packets of data in the lanes. An indication can be passed back upstream about the invalid lane so that the lane can be reset. Error correction can be provided by reconstructing the bit data in the invalid SerDes lane based on parity information in an optional parity lane.

摘要： A method, medium, and wireless system are provided for scheduling access terminals to prevent starvation of other access terminals connected to a communication network. The wireless system includes access terminals and base stations that are configured with a first wireless scheduler and a parallel wireless scheduler that select access terminals to communicate during specified time slots. The access terminals may measure channel conditions associated with communications to the base station and transmit requests that specify a desired communication rate to the base station. The first and parallel wireless schedulers on each base station receive the requests from each access terminal and select an access terminal to communicate during a subsequent time slot that may be based on, for example, the channel conditions and weighted average functions of the communication rates—corresponding to the access terminal—generated by the first and parallel wireless schedulers.

摘要： A multimedia server includes a first transceiver that modulates a data signal to produce a first radio frequency (RF) signal and that transmits the first RF signal to a client over a first transceiver channel when the first transceiver is in a transceive mode. The first transceiver includes a first channel control that performs a first channel scan when the first transceiver is in a scan mode, that determines at least one performance parameter of the first transceiver channel and asserts a low performance signal when the at least one performance parameter compares unfavorably to a performance threshold, and that switches the first transceiver to a selected alternative transceiver channel when the low performance signal is asserted.
