摘要： A video signal recording and playback apparatus and method which is applicable to wide-band recording in which a video signal is divided into a plurality of channels by time-axis expansion, and the channels are recorded in parallel on respective tracks. Prior to recording, a reference signal consisting of a plurality of different signal bursts, each having a specific frequency and each being superimposed on a specific DC level, is inserted into blanking intervals of the video signal and recorded therewith. On playback, the amplitudes of the signal bursts in the reference signal are monitored, and playback equalizers are controlled accordingly such as to maintain a predetermined equalizer characteristic and to maintain identical overall frequency characteristics for the various channels.

摘要： A video signal recording and playback apparatus for recording each field of a video signal as a plurality of segments on a plurality of tracks, including means (23) for inserting segment index signals after conversion of the video signal to a recording signal, to be recorded together with the recording signal to designate the respective segments. During varied-speed playback operation, the segment index signal are detected (33) in the playback signal, and the data thus obtained are used to control the operation of a memory (35) which temporarily stores successiveliy produced portions of the playback signal. A playback signal can thereby be obtained by combining output signals from the memory (35), which will produce a satisfactory display image during varied-speed playback operation, e.g. during high-speed playback, with only simple signal processing being required.

摘要： A video signal recording method and apparatus for-recording each field of a video signal as a plurality of segments on respective tracks of a magnetic tape, in which each segment consists of a sequentially-ordered set of scanning lines which constitite a fraction of the total scanning lines of the field and which extend substantially over the entire field, for example all of the even-numbered or all of the odd-numbered lines of the field. Since each recording track contains scanning lines extending sequentially over one field, a playback signal providing a correctly ordered display image is obtained for playback operation at speeds higher or lower than the standard speed, while utilizing the same recording and playback signal processing circuits as are utilized during standard speed operation.

摘要： A signal processing apparatus comprises a reference inserting circuit (17, 18, 19) for inserting a reference waveform, preferably a ramp, at periodic intervals into an analog information signal. The reference waveform varies in the range of amplitude variations of the information signal. A reference detector circuit (56A, 56B) detects the inserted reference waveform from the signal as the latter is reproduced from a recording medium or received through a transmissions medium. The detected reference waveform and the information signal are alternately applied to a transfer circuit (58A, 58B; 100A. 100B; 200A. 200B) having a transfer function describing the relationship between the original reference waveform and the detected reference waveform which has been affected by errors present in the apparatus. The transfer circuit generates the transfer function at periodic intervals in response to the detection of error-affected reference waveform and transforms the waveform of the information signal according to the transfer function.
