TELEVISION SIGNAL TIME BASE CORRECTOR Abstract of the Disclosure A video signal processor for improving the information content of video input signals coupled thereto and capable of operation in several unique distinct modes. In a first mode of operation, the invention produces broadcast quality monochromatic or color video signals from monochromatic or direct input color video signals reproduced by a V-LOCK signal source, e.g. a capstan servo video tape recorder. In another mode of operation, the invention produces broadcast quality direct color video signals from processed color video signals supplied by a V-LOCK video signal source. In another mode of operation, the invention produces mono- chromatic or color video signals having a substantially reduced time base error from monochromatic or color video signals reproduced by a LINE LOCK video signal source, such as a non-capstan servo video tape recorder. In another mode of operation, the invention produces from processed color video signals supplied by a LINE LOCK source color video signals, termed quasi-direct color signals, which are properly phased so that they may be dubbed up to a quadraplex video tape recorder or a capstan servo video tape recorder and reproduced a second time as broadcast quality direct color video signals.
