摘要： Point to multi-point wireless video delivery. Among a group of receiver wireless communication devices (RXs), one is designated (e.g., as acknowledgment (ACK) leader). Media delivery operational parameters are selected based on the designated RX or based on all or a subset of the RXs. For simultaneous media delivery to multiple RXs, characteristics associated with the designated RX [or all, or a subset or RXs] govern the manner by which communications are made. Different respective RXs may be designated to serve in this role at different times. Wireless delivery of media (e.g., video signaling, audio signaling, etc.) to a group of RXs is effectuated in accordance with modified multicast signaling with a designated leader (e.g., ACK leader). Among a group of devices, a least successful receiving device that still receives media at an acceptable level may be chosen as the designated leader (e.g., ACK leader).

摘要： Adaptive video encoding based on predicted wireless channel conditions. Based on at least one of a number of transmitter side indications of the available throughput of a wireless channel for video delivery, an encoder rate adaptation mechanism generates an estimate of the supportable throughput of the wireless channel under different operating conditions. An encoding parameter, such as encoder bit rate, is subsequently altered based on the estimated throughput value. In one instance, transmitter side throughput indicia is used to generate target encoder bit rates for multiple potential PHY data rates/channel MCS selections that may be used in video delivery. In anticipation of or immediately following a transition to one such PHY data rate/MCS selection, the encoder bit rate is altered in accordance with an associated target bit rate. In another mode, average transmit queue latency information is used to further regulate the encoder bit rate.

摘要： 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. Each respective encoding and/or transcoding may be particularly optimized or tailored for a given media element type.

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., which frequency spectra to use, duration of such communications, modulation coding set (MCS) to use, etc.).

摘要： 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.

摘要： A wireless media network enables bridged control of multiple media devices via multiple different transport media. The system enables input devices to control various output devices by mapping the input devices to the output devices. The system can map inputs to controls for output devices to enable a user to control various output devices via inputs initially provided to a different input device in a media device network. Input information can be stored and assigned to a certain input device. Input devices can multicast to various different output devices using a common signal configuration. Signals between an input device and an output device can be use a substitute signal configuration that is to enable implementation by the output device. Signals can be exchanged between over various transport media by encapsulating signals prior to transport, which can include encoding signals with additional security protocols.

摘要： 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.
