20140223504 | CABLE DISTRIBUTION NETWORKS - Methods and systems are provided for cable distribution networks, in which a headend may generate one or more downstream signals for communication in a distribution network associated with the headend. The generating of the one or more downstream signals may comprise combining data and/or video for one or more service groups, from signals corresponding to a plurality of services, with the combining being performed in digital domain. The distribution network comprises a cable distribution network, such as a hybrid fiber-coaxial (HFC) based network. The plurality of services comprises cable television (e.g., DOCSIS) services, VOD services, SDV services, OOB services, and/or broadcast television services. The headend may control feedback from the distribution network, and may control the combining performed therein based on the received control feedback. The control feedback may be received from, for example, fiber nodes and/or user equipment in the distribution network. | 08-07-2014 |
