METHOD AND SYSTEM FOR LIMITING CONTENT DIFFUSION TO LOCAL RECEIVERS

摘要

A system for transmitting content within a predetermined region comprises: a content source selectively transmitting control signals and content; a first channel transmitting data and having an unrestricted range; a second channel transmitting data and having a restricted range. A sink is connected to the content source by the first channel to receive content and is connected to the content source by the second channel to receive the control signals. The content is transmitted over the first channel only after a first signal is sent by the source to the sink over the second channel and the first signal is either returned or acknowledged by the sink.
