Abstract
An interactive television system that renders on-demand interactive multimedia services for a community of users. The interactive multimedia is delivered to each user on a TV or on a LAN-node (Local-Area-Network) computer through an 'interactive TV channel' created and controlled by a Channel-processor, which can be implemented as either a PC or a high-end workstation. The system employs a direct-access on-demand workgroup server. It is equipped with the primary on-demand multimedia data base stored on a hard disk subsystem that is connected directly to the Channel-processors through an internal workgroup link. Using a no-overhead server technology, the connected workgrouped Channel-processors can all concurrently retrieve and process the data directly from the hard disk subsystem without resorting to a stand-alone server system for data retrieving and downloading. The system also employs peer-to-peer workgroup connectivity, so that all of the workgrouped Channel-processors that are connected to the workgroup server through the internal workgroup link, can communicate with one another.

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.
