Abstract
A single centralized video controller is employed to convert and distribute video channels to one or more analog TVs (i.e., viewing devices or the like). This is realized without the need for changes to either the TVs or the interconnecting COAX. Specifically, the centralized controller includes one or more MPEG2 decoders, the number of which depends on a desired number of active TVs to be used in viewing different programs, and one or more wireless (e.g., radio frequency (RF)) communications links to television controllers (i.e., remote control units) associated on a one-to-one basis with the desired number of TVs. In operation, channel selection for each of the one or more TVs is communicated up-stream from the centralized controller to a remote video server and, therein, to a video services controller. The video services controller causes the video server to transmit only the selected program channels to the local centralized video controller. However, when the video channel is already being supplied from the video server to an optical line terminal and, specifically, to an optical line card to which the requesting centralized controller is connected to, there is no need to communicate the channel request to the video server. The optical line terminal simply supplies the requested channel via an optical line card to the additional requesting centralized controller and, in turn, to the requesting TV.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
