Method and apparatus for electronically processing and rerecording recorded video signals

Claim 1

A method of electronically processing video signals recorded on a first record carrier, comprising the steps of: (a) reading original video signals which are previously recorded on the first record carrier and represent a predetermined number of frame sequences, frames or partial frames and writing the original video signals into an intermediate memory; (b) then interrupting the reading of further original video signals from the first record carrier and/or their transfer into the intermediate memory; (c) processing with a processor the video signals written into the intermediate memory so as to be corrected, modified and/or retained in a predetermined manner; (d) writing the processed video signals into one of the intermediate memory and another memory; (e) recording the written processed video signals from the one of the intermediate memory and another memory on the first record carrier such that the frame sequences, frames or partial frames produced therefrom during playback take on a predetermined local and time position, and each processed video signal is recorded on such a surface or such surface sections of the first record carrier which are not occupied by the original video signal to be processed; (f) thereafter, interrupting the recording on the first record carrier; and (g) repeating steps (b) to (f) a predetermined number of times for further original video signals to be processed.

Claim 2

A method of electronically processing video signals recorded on a first record carrier, comprising the steps of: (a) reading original video signals which are previously recorded on the first record carrier and represent a predetermined number of frame sequences, frames or partial frames and writing the original video signals into an intermediate memory; (b) then interrupting the reading of further original video signals from the first record carrier and/or their transfer into the intermediate memory; (c) processing with a processor the video signals written into the intermediate memory so as to be corrected, modified and/or retained in a predetermined manner; (d) writing the processed video signals into one of the intermediate memory and another memory; (e) recording the written processed video signals from the one of the intermediate memory and another memory on the first record carrier such that the frame sequences, frames or partial frames produced therefrom during playback take on a predetermined local and time position, and each processed video signal is recorded on such a surface or such surface sections of the first record carrier which are not occupied by the original video signal to be processed; (f) thereafter, interrupting the recording on the first record carrier; and (g) repeating steps (b) to (f) a predetermined number of times for further original video signals to be processed.

Claim 12

An apparatus for electronically processing video signals recorded on a record carrier, comprising: a video recorder having means for still picture playback, a head arrangement for transmitting video signals to and from the record carrier and that can be switched between recording and playback and a controllable start-stop device for starting and stopping the transmission of video signals to and from the record carrier; a memory connectable to said head arrangement to be fed thereby with video signals corresponding to a frame sequence, a frame or a partial frame during the transmission of video signals from the record carrier; a processor for processing the video signals transmitted to said memory while transmission of video signals to and from the record carrier is interrupted, and storing the processed video signals in said memory; means for transmitting the processed video signals from said memory to said head arrangement to be recorded thereby on the record carrier; means for driving said head arrangement and the record carrier relative to each other; and means for interrupting the relative drive for the duration of video signal processing, said interrupting means being responsive to reaching a predetermined fill level in said memory for providing a control signal to said start-stop device so as to stop said drive means for storage of video signals coming from said head arrangement, and to start for storage of processed signals.

Claim 13

An apparatus for electronically processing video signals recorded on a record carrier, comprising: a video recorder having means for still picture playback, a head arrangement for transmitting video signals to and from the record carrier and that can be switched between recording and playback and a controllable start-stop device for starting and stopping the transmission of video signals to and from the record carrier; a memory connectable to said head arrangement to be fed thereby with video signals corresponding to a frame sequence, a frame or a partial frame during the transmission of video signals from the record carrier; a processor for processing the video signals transmitted to said memory while transmission of video signals to and from the record carrier is interrupted, and storing the processed video signals in said memory; means for transmitting the processed video signals from said memory to said head arrangement to be recorded thereby on the record carrier; means for driving said head arrangement and the record carrier relative to each other; and means for interrupting the relative drive for the duration of video signal processing, said interrupting means being responsive to reaching a predetermined fill level in said memory for providing a control signal to said start-stop device so as to stop said drive means for storage of video signals coming from said head arrangement, and to start for storage of processed signals.
