Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for channel bonding in an adaptive coding and modulation mode. In some implementations, a system receives packets of a data stream for transmission in a satellite communications system. The system determines a modulation and coding arrangement for the received packets. The system generates code blocks that include data from the packets of the data stream. The system assigns the generated code blocks for transmission on different carriers. One or more of the different carriers is operated in an adaptive coding and modulation mode to support multiple modulation and coding arrangements within a single carrier. The system transmits the code blocks on the different carriers using the determined one or more modulation and coding arrangements.

This invention is related to automatic monitoring and collaboration among aircrafts. Specifically, an aircraft receives the current and future state of adjacent aircrafts by broadcast, then analyzes the start time of collaborative tasks. Base on the start time and prior knowledge, it adjusts automatically the prediction accuracy requirements of its future states, the check interval of predicted state errors and the minimum check interval. And it makes a new prediction and broadcasts new future states based on the check results of prediction errors. In the invention, an aircraft does not periodically broadcast its states, but broadcasts irregularly its future states according to its current tasks, its states and surrounding environment. The invention guarantees that collaborative tasks can be can be correctly carried out among aircrafts while it reduces the bandwidth requirement of wireless communication. It provides guarantee of high density flight and collaboration among many aircrafts.

A plurality of digital video recorders are polled to extract data indicative of recordings scheduled thereon. The polling is carried out over a video content network by a component at a node in the video content network that is remote from the plurality of digital video recorders. At least a portion of the data is used to obtain a prediction of future switched digital video channel usage for the video content network. At least one network management activity is carried out on the video content network in response to the prediction of future switched digital video channel usage for the video content network.

A new television broadcast model called a Broadcast Market Exchange (BMX) eliminates the inefficiency in spectrum usage, providing maximum flexibility in delivering content through either VHF (for fixed location receiving devices) or UHF (optimized for mobile receiving devices) transmission/propagation. In conjunction with the BMX, a wireless communications system architecture is provided to enable a broadcast augmentation channel. The augmentation channel provides supplementation of the Quality of Service (QoS) of a one way User Datagram Protocol (UDP) delivery environment. The augmentation channel may be comprised of one or more physical delivery mechanisms (wired or wireless), but can be effectively unified for increasing QoS and or scalable levels of service (additional essence) to improve the user experience.

A method and system optimally selecting antenna elements based on the current availability of antenna elements and the current usage of other antenna elements within a two or three dimensional array. The present system and method pertain to an approach to allow the maximal usage of each antenna element while simultaneously reducing the coupling between antenna elements to improve the signal strength in each antenna element by ensuring that antenna elements in the same incident path are not tuned to the same frequency or physically or electrically near elements tuned to identical or adjacent frequencies.

A broadcast/broadband convergence system that delivers content from content sources to user equipment devices. The system provides: significantly enhanced mobile capability to the broadcast industry; an additional revenue source for the broadcast industry by dynamically selling available spectral resources for use by wireless broadband networks and/or broadcast content off-loaded from wireless broadband networks; additional spectrum for the broadband industry through the dynamic purchase of available spectrum; and an enriched user experience. A spectrum server may facilitate the dynamic allocation of radio spectrum made available by the broadcast networks. The broadcast networks may broadcast with enhanced waveform parameters to support mobile devices as well as fixed devices.
