Abstract
The OD servers, encoders, NOD servers and CPUs supply voice data, character data and remote control data together with the control information. A transmitter modulates the control information and voice data, etc. by the QPSK modulation method. An infrared ray emitter outputs the modulated infrared ray depending on the modulated signal. A receiving apparatus reproduces acoustic signal from the modulated infrared ray and displays characters and also transmits the signal corresponding to the remote control data to the transmitting apparatus with the infrared ray. An infrared ray detector receives the modulated infrared ray output from the receiving apparatus. Thereby, with this system, the signal, required by the receiving side or suitable for the condition of the receiving side, supplied through many channels can be transmitted without any restriction on the wiring.

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.
