Abstract
In a recording system, a sequence of image signals obtained from a sequence of images are used to generate and record a sequence of recordable signals on a read only memory. Efficient coding of the received sequence of image signals is carried out through the use of a given parameter which is adaptively and dynamically changed, preferably manually, through a parameter controller acting as the interactive device. The image signals are repeatedly subjected to the efficient coding process. The process uses a sequence of predictive signals to produce coded signals. The predictive signals are displayed on a monitor display device to be monitored by an operator. The operator changes the attributes of the parameter until an optimum image is obtained. The optimum parameter is stored on a magnetic tape. The image signals subjected to the efficient coding enable the production of a sequence of coded image signals which are recorded on the read only memory in synchronism with the optimum parameter, after the optimum image has been obtained.

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.
