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.
