Abstract
A coupling device for coupling a videotelephone with a video generation device. The coupling device includes (i) a first device, for detecting at least one code word contained in a signal originating from the videotelephone, (ii) a second device, coupled with the first device, for generating a control signal in response to the detected code word, and (iii) a change-over device. The change-over device is coupled with the first device and with the second device. The change-over device receives, from the video generating device, both a first video signal, coded in a first manner, and a second video signal, coded in a second manner. The change-over device then feeds, in response to a control signal, coded video signals originating from one of a number of video generating devices to the first device via the change-over device. The coupling device is readily applicable in multicast environments.

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.
