System and methods for mapping and demapping digitized signals for optical transmission
An optical network includes a transmitter portion configured to transmit a digitized stream of symbols over a digital optical link, a mapping unit disposed within the transmitter portion and configured to code the transmitted digitized stream of symbols with a mapping code prior to transmission over the digital optical link, a receiver portion configured to recover the coded stream of symbols from the digital optical link, and a demapping unit disposed within the receiver portion and configured to map the recovered coded stream of symbols into an uncoded digitized signal corresponding to the digitized stream of symbols at the transmitter portion prior to coding by the mapping unit.

Digital domain content processing and distribution apparatus and methods
Methods and apparatus for distributing content using a spectrum generation device. In one embodiment, digital content is received via a time-multiplexed network transport (such as Gigabit Ethernet), and converted to frequency channels suitable for transmission over a content distribution (e.g., Hybrid Fiber Coaxial (HFC)) network. In one variant, the conversion is performed using digital domain processing performed by a full spectrum generation device. Additionally, methods and apparatus for selectively adding, removing, and/or changing digital content from the full spectrum device are also disclosed. Various aspects of the present invention enable physical (infrastructure) consolidation, and software-implemented remote management of content distribution.

On demand linear programming
Linear content holds great value to consumers, and by delivering it to consumers on demand, service providers can improve the user experience for their consumers. A consumer requests linear on demand content by selecting channels and time ranges or content items, or bundles thereof, which the service provider broadcasts as linear content. The requested content is broadcast, and repackaged as an unbroken block of content for the consumer during the requested time range or the duration of the content item. By repackaging the linear on demand content, the service provider may provide greater options to consumers without significantly increasing the amount of bandwidth used in its network to deliver that content. Channel guides and viewing features are tailored for the requested content to further improve the user experience.
