摘要： In a signal record/playback apparatus and its method which performs the recording for recording a signal on the recording medium DISK and the playback for playing back the recorded signal from the recording medium DISK at the same time, the recording position and the playback position are set independently and arbitrarily. Record starting position information PREC on the recording medium DISK for starting the recording is stored, playback starting position information PPB on the recording medium DISK for starting the playback is stored, and the recording based on the record starting position information PREC and the playback based on the playback starting position information PPB are independently performed, so as to realize a signal record/playback apparatus and its method which can set the record starting position PREC and the playback starting position PPB arbitrarily.

摘要： A detecting circuit detects a moving vector for each block. Corresponding to the moving vectors, a plurality of moving portions in one field are extracted. Thus, a moving vector of each moving portion is generated. In a field memory, a motion compensating process is performed corresponding to the moving vectors. A field difference between the input signal and a signal that has been movement-compensated is supplied to an Hadamard transform circuit. The Hadamard transform circuit divides the field difference signal into a plurality of frequency components. A non-linear circuit has noise components corresponding to individual frequency bands. An output signal of the non-linear circuit is supplied to an inverse-Hadamard transform circuit. The inverse-Hadamard transform circuit performs an inverse-Hadamard transform process. The resultant signal is subtracted from the input picture signal.

摘要： By reducing the number of seek operations in an operation to play back a signal from a recording medium, the amount of data temporarily stored in a read buffer memory employed in a signal recording/playback apparatus is large enough to be output as a playback signal during a seek operation, allowing a continuous playback operation to be carried out. In order to reduce the number of seek operations, a signal is always recorded onto the recording medium in continuous free areas each having a size equal to or larger than a predetermined recording/playback time length which is typically set at 1 minute. If it is necessary to insert an additional signal having a length smaller than the predetermined recording/playback time length into a point of insertion in an area already occupied by an existing signal, a continuous free area with a size equal to or larger than the predetermined recording/playback time length is newly allocated to the additional signal. The additional signal is then recorded in the free area instead of being inserted into the point of insertion. Since the free area is larger in size than the length of the additional signal, the rest of the free area is filled up with a portion of the existing signal adjacent to the point of insertion.

摘要： A method and an apparatus for recording and reproducing a TV broadcasting signal includes a CM detecting unit, a write data processing circuit, a recording system control circuit, and a recording medium. The CM detecting unit operates to detect if a TV broadcasting signal composed of a RF signal inputted through an antenna is now a CM. The write data processing circuit operates to generate CM information accompanied with the CM detected by the CM detecting unit. The recording system control circuit operates to record on the recording medium the CM information generated by the write data processing circuit together with a video signal and an audio signal.
