Title: AM interference reduction
Inventor: HAWKES HENRY WILLIAM
IPC: H03D1/22
Filed: 1990-04-20
Abstract: Reducing the interference caused by one received AM signal to another such signal, the received signals together forming a composite signal, by extracting the carrier of one signal 1 and mixing 4 a version of that carrier with either the composite signal itself or a processed version thereof, whereby the mixing yields a component, at p, at the beat-frequency between the carriers of the two signals and having the modulation of the other signal. In one embodiment the two carriers  OMEGA 1 and  OMEGA 2 are extracted by circuits 1 and 2, one carrier,  OMEGA 1, is quadrature phase-shifter at 3 and mixed at 4 with the composite received signal to yield at p the beat-frequency OMEGA  beta  between the two carriers and having the modulation on OMEGA 2. The quadrature version of  OMEGA 1 is also mixed with the other carrier  OMEGA 2 at 7 to yield an unmodulated  OMEGA  beta which is divided into the modulated  OMEGA  beta  signal at 9, the output being the modulating frequency, preferably of the weaker of the two signals. To avoid divider problems arising each time  OMEGA beta approaches zero amplitude, the above output may be gated. In another embodiment a harmonic series of components is generated, mixed with the modulated beat frequency from P, passed into a rapid roll-off filter and then into a full wave rectifier detector to derive the modulating signal. Modulation relating to the stronger of two signals may also be obtained. <IMAGE>

Title: Combining photographic film material or the like and digital video signals
Inventor: RICHARDS JOHN WILLIAM
IPC: G11B27/032
Filed: 1990-11-15
Abstract: A system for combining a 60 field/s 2:1 interlace scan format digital video signal and 30 or 60 frame/s source material, such as film, employs a film scanner 252, 258 to produce a digital video signal from a 30 frame/s source film 240, 242, a film scanner 266 to produce a digital video signal from a 60 frame/s source film 244, a post-production system 272 for combining with that signal the 60 field/s 2:1 interlace scan format digital video signal (for example from a VTR 248 or camera 246 to produce a signal which may be output in 60 field/s 2:1 interlace scan format, or in 30 frame/s progressive scan format for recording on film 298. Motion compensated interpolation is employed, where necessary, at stages of field rate conversion. In order to obviate the need for more than one stage of motion compensated interpolation between the primary sources and primary outputs, the post-production system operates on signals in 60 field/s 2:1 interlace scan format, and motion interpolated compensation is performed only during conversion (at 256, 262) of the 30 frame/s 1:1 progressive scan format signal to the 60 field/s 2:1 interlace scan format. The conversion of the combined 60 field/s 2:1 interlace scan format signal to 30 frame/s progressive format (at 176) does not require motion compensated interpolation because the frame rate is unchanged. <IMAGE>
