Abstract
Official abstract text for this publication.
Methods and apparatus for inserting local content of interest in an all digital content delivery network. In one embodiment, the content delivery network comprises a cable television or satellite network, and an RF channel thereof is separated or isolated from an incoming multiplex of all-digital content transmission. The separated RF channel is demodulated to provide a multiplexed transport stream, and packets corresponding to one or more programs from the transport stream are replaced with packets obtained from local compression and encoding of analog programming such as e.g., personal, educational and government (PEG) programming. The inserted programming may also contain closed captioning and emergency data alerts. The resulting encoded transport stream is then re-inserted into the multiplex, modulated, and put back onto the RF channel. In an alternate embodiment, space is reserved within the downstream multiplex so as to avoid having to remove an existing program stream.
First claim
Opening claim text (preview).
What is claimed is: 1. A system configured to distribute at least one of public, education or government content, said system comprising: a content distribution network configured to provide a digital multiplex of a plurality of program streams to a node on said content distribution network; a local content insertion device disposed at said node and in signal communication with said content distribution network; a receiver disposed at a premises of a user of said content dis…
