Abstract: A system and method for the expansion of the spectrum by the generation and introduction of high frequency spectrum overlays is disclosed. In an electronic content distribution system a plurality of input stream are combined at a head end into two combined signals having separate frequency band ranges. The signals are transmitted to the network and are dynamically combined into a single signal where the spectral composition of the signal is controlled by pre-defined parameters. The first signal carries a plurality of existing channels while the second signal could carry an additional set of channels. The second signal could carry spectral overlays generated from specific input streams the in accordance with pre-defined system parameters. The spectral overlays are selectively extracted from the second signal and introduced into the combined signal in the network in accordance with pre-defined subscriber-specific information.

Abstract: A method and system to be utilized for the provision of a True Video-on-Demand service to paying subscribers of a communication network. The typical T-VoD-specific objectives are accomplished by the optimization of the content distribution efficiency, by the enhancement of the content request options, by the improvement of the content access capabilities, and by the substantially improved handling of content information units. The system and method provides a wide selection of video titles stored on a high-speed high-capacity video object depository within the network. A plurality of video object accessible and transmittable at substantially improved transmission rates are stored temporarily on subscriber equipment devices and enable controllable and dynamic display and interaction including full VCR-like capabilities.
