Abstract
An authoring system for interactive video has two or more authoring stations for providing authored metadata to be related to a main video data stream and a multiplexer for relating authored metadata from the authoring sources to the main video data stream. The authoring stations annotate created metadata with presentation time stamps (PTS) from the main video stream, and the multiplexer relates the metadata to the main video stream by the PTS signatures. In analog streams PTS may be created and integrated. In some embodiments there may be multiple and cascaded systems, and some sources may be stored sources. Various methods are disclosed for monitoring and compensating time differences among sources to ensure time coordination in end product. In different embodiments transport of metadata to an end user station is provided by Internet streaming, VBI insertion or by Internet downloading. User equipment is enhanced with hardware and software to coordinate and present authored material with the main data stream.

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.
