Abstract (en)
[origin: WO0211451A1] A system architecture for controlled distribution of video, and/or audio, and/or data (v/a/d) within a home or business includes a single "mini headend" (302) for receiving v/a/d (308) signals and for distributing the v/a/d (308) to presentation units (304) within the home or business. The mini headend (302) may receive v/a/d (308) from various sources. Based on control signals received from one or more control units (306), the mini headend (302) selects v/a/d (308) signals for modulation onto a plurality of carrier signals or communication channels. The modulated carrier signals are multiplexed into a distribution signal which is transmitted to the presentation units (304).
