Abstract: Methods, systems, and devices are described for communicating data from multiple data terminals to an aggregator terminal over a communication link having changing link conditions. In some embodiments, source data is received at multiple data terminals, each in communication with an aggregator terminal over a communication link. For example, during a live newscast, one mobile camera may receive live video of an event from a first position while another mobile camera receives live video of the event from a second position. For various reasons (e.g., as the cameras move) each communication link may experience independently changing link conditions. Each data terminal encodes the source data (or store source data for later encoding) as a function of its respective link conditions and transmits encoded source data over its respective communication link to the aggregator terminal.

Abstract: Methods, systems, and devices are described for providing predictive adaptive communications. Embodiments include a network access unit, in communication with multiple data terminals, and adapted to determine geospatial and other network data (e.g., current capability and position information relating to a designated one of the data terminals, map data, etc.), and to generate a link condition prediction as a function of the network data. The network access unit may then adaptively encode source data (e.g., using adaptive coding and modulation of hierarchically pre-coded data) to preempt impacts of changing link conditions on communications with the designated data terminal as a function of the link condition prediction.

Abstract: Methods, systems, and devices are described for using adaptive coding and modulation (“ACM”) to adaptively communicate with a plurality of data terminals having different capabilities. Embodiments provide hierarchical communications of content, generated by applying hierarchical pre-coding schemes to the source data and then associating the pre-coding levels with coding and modulation schemes of varying order. The pre-coding and/or coding and modulation may be based on one or more capabilities of the data terminals in the network. In some embodiments, data terminals may be used to cache certain data intended for other data terminals, for example, to allow time-shifted playback of the content on terminals with varying capabilities.
