| Number | Title | Issue Date |
| 5218447 | Method and apparatus for identifying the reproduction mode of a video tape recorder A reproduction mode identification circuit (1) is responsive to a horizontal synchronizing signal and a color rotary pulse for identifying whether the reproduction state of a double azimuth 4 head system VTR is the search reproduction or not of the SP mod... | 06/08/1993 |
| 5179450 | Video signal processing apparatus and method for the time base compensation A video signal processing apparatus and method are provided in which time base errors in the luminance and color signals of a video signal reproduced from a recording medium are compensated. Time base errors in the luminance signal are reduced by storing ... | 01/12/1993 |
| 5063437 | Method and apparatus for processing a color video signal This invention relates to a method and apparatus for processing a color video signal. The processing method separates an input composite color video signal into a luminance signal and chrominance signal, demodulates the separated chrominance signal into c... | 11/05/1991 |
| 4905099 | Intermediate picture field storage system for variable speed magnetic tape video data read-out Four picture field memories which contain storage places for luminance data, chrominance data, error flags and write flags are switchable from write in to read out by changeover switches controlled by an access control unit for connection of the address a... | 02/27/1990 |
| 4791499 | Method and apparatus for reproduction of video signals from magnetic tape at a tape transport speed differing from that of recording In a magnetic tape machine which can be played to reproduce television pictures at speeds different from the recording speed, in connection with which the video signals are stored in a picture memory, the video signals are stored under group addresses in ... | 12/13/1988 |
| 4672469 | Delay time adjusting system for video signal reproducing apparatus having heads scanning across multiple tracks A delay time adjusting system comprises a comparing circuit for comparing levels of reproduced frequency modulated signals from a pair of rotary heads which simultaneously scan over a magnetic tape, where the rotary heads have gaps of mutually different a... | 06/09/1987 |
| 4635134 | Video signal processing apparatus for processing video signals at the time of a special reproduction mode A video signal processing apparatus for processing a video signal at the time of a special reproduction mode comprises an A/D converter for converting a reproduced video signal obtained by demodulating a frequency modulated signal reproduced from a record... | 01/06/1987 |
| 4504869 | Color moviola for two-track VTR When in the high or low speed editing or "moviola" mode, a VTR switches the inputs of Y and C demodulators between the Y and C heads or switches the demodulator outputs as the heads cross tracks. Thus, the Y and C demodulators always receive or provide at... | 03/12/1985 |
| 4459620 | Color video signal reproducing apparatus A color video signal reproducing apparatus, such as a VTR, is capable of being operated in a normal speed reproduction mode, as well as in non-normal modes such as stop motion, slow motion, and fast motion. A rotary pick-up head on the apparatus is mounte... | 07/10/1984 |
| 4423497 | Rotary recording medium reproducing apparatus capable of performing special reproduction A rotary recording medium reproducing apparatus for reproducing a rotary recording medium in which an information signal is recorded on a spiral track comprises a reproducing transducer having a reproducing element for reproducing signals from tracks on t... | 12/27/1983 |
| 4361849 | Video disc vari-speed playback system A video disc player has two fields of buffer storage for implementing special effects. Video signal recovered from a disc record is directed into respective ones of the buffer stores for subsequent replay in particular sequences. A fixed memory device, co... | 11/30/1982 |
| 4355324 | Sampled or digitized color in a high speed search record and replay system Moviola color picture quality is improved for a record and replay system wherein video sampled at a predetermined multiple of the color subcarrier frequency is recorded with each frame or field being disposed on a set of multiple tracks and with only a po... | 10/19/1982 |
| 4346397 | Apparatus for reproducing a video signal of one system with conversion to a video signal of another system A reproducing apparatus reproduces a video signal of a certain system having a field frequency F1 and a number N1 of horizontal scanning lines within one field period which has been recorded on a magnetic tape travelling at a speed S1 along plurality trac... | 08/24/1982 |
| 4290081 | Method and apparatus for stop frame reproduction in television picture fields each recorded on tape in a plurality of adjacent tracks Successive picture fields in normal operation are successively written into a one-field memory and displayed by nondestructive read-out. A stop order stops the tape while the last recorded picture field is continuously displayed and backs up the tape to a... | 09/15/1981 |
| 4283737 | Video signal reproducing apparatus with circuit avoiding skew distortion when operated at abnormal speed and/or direction In an apparatus for reproducing video signals recorded in successive, obliquely extending parallel tracks on a record tape with the horizontal synchronizing pulses of video signals recorded in nearby tracks being offset from each other by a predetermined ... | 08/11/1981 |
| 4215362 | Track selection method and apparatus In an apparatus for automatically maintaining a transducing head assembly on the proper track, which is particularly adapted for a helical scan recording and/or reproducing apparatus capable of providing special motion effects, track selection method and ... | 07/29/1980 |
| 4131912 | Apparatus for recording and reproducing video signals on a magnetic tape movable at different speeds In apparatus for recording and reproducing video signals in successive parallel tracks on a magnetic tape by means of magnetic heads or transducers repeatedly traversing the tape at a steady rate while the tape is driven longitudinally, and in which at le... | 12/26/1978 |
