Title: Apparatus for removing ghost component disturbing picture signal
Inventor: NISHI YUJI
IPC: H04N5/21
Filed: 1991-10-20
Granted: 1997-03-18
Abstract: An  apparatus  for  removing  a  ghost  component which disturbs  a picture  signal  by means  of  a  ghost canceling  reference  signal  included  therein.    The reference signal is extracted from the picture signal and judged  as  to  whether  it  has  a  specific  level  in  a reference time interval.  The extracted reference signal is also judged as to whether a color burst signal is canceled.   If both judgments are positive, a judgement signal is generated which allows the extracted signal to be examined how it is disturbed by the ghost component.          In response to the examination,  the ghost component is removed from the picture signal.

Abstract: A digital transmission and/or recording system for component-coded colour-TV  signals. At present, no professional video recorders are available which can record progressive 16:9-format 625-line TV  images. Digital studio video recorders operating by the D1 process can only record the YUV components of interlaced 4:3-format 625-line images. By means of vertical sub-scanning of the UV-components and subsequent block companding using special encoding techniques within 8-byte blocks (40), the neces-sary memory capacity is made available for recording progressive 16:9-format 625-line TV images.
