摘要： A social networking system enables sharing of content between various members, devices, infrastructures, and the like based upon membership in a social network (SNET group). Content can be protected by limiting access to the content to members of an SNET group, members associated with various devices docked to the SNET group, and the like. Joint access of content by various members of an SNET group can be managed to ensure synchronized access of content and interactions between SNET accessing group members. Instances of a content item can be distributed to multiple destination devices associated with an SNET group, where various instances are transcoded to accommodate varying capabilities and characteristics of various communication pathways and the destination devices and ensure synchronized access of the content item by the multiple destination devices. Interactions between members of an SNET group can be managed to leverage links to other SNET groups.

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： 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.

摘要： A link pulse translation circuit includes transmit portion circuitry that receives a first link pulse signal, having a first level, from a physical layer device. The transmit portion circuitry translates the first link pulse signal into a second link pulse signal that has a second level suitable for driving transmit portion circuitry of an optical transceiver. Receive portion circuitry receives a signal detect signal from receive portion circuitry of an optical transceiver, the receive portion circuitry of the optical transceiver asserting the signal detect signal in response to an optical pulse signal being provided on an optical medium to which the receive portion circuitry of the optical transceiver is coupled. The receive portion circuitry provides a third link pulse signal, having the first level and corresponding to the optical pulse signal, to the physical layer device.
