摘要： A write-once recording medium preserving a data recording status of the write-once recording medium, a method of preserving the data recording status of a write-once recording medium, a medium including computer readable code for the same, and a recording and/or reproducing apparatus therefor. In the method of preserving the data recording status of a write-once recording medium, first, data is recorded on the write-once recording medium. Next, recording-status data, representing occupied areas, is produced and recorded in a temporary defect management area allocated in the write-once recording medium. Thereafter, a finalization command is received to preserve the data-recording status of the recording medium. Then, in response to the finalization command, predetermined data is recorded in a temporary defect management area to prevent further data recording on the write-once recording medium. Accordingly, the data recording status of the finalized write-once recording medium can be preserved.

摘要： A recording medium for storing encrypted audio data, an apparatus and a method for recording the same, and an apparatus and a method for reproducing the same. Encrypted and unencrypted audio data corresponding to an audio program to be reproduced, such as a musical selection, are recorded in different areas of a recording medium. The encrypted audio data allows a reproduction of the audio program with a sound quality far better than a reproduction of the audio program using the audio data which is not encrypted. The audio data is encrypted and recorded to prevent illegal copying of the higher quality sound data. Accordingly, audio data may be reproduced using the unencrypted audio data in a reproducing apparatus complying with existing specifications. Higher quality audio may be reproduced from the encrypted audio data using the present invention.

摘要： A video recording apparatus to record a television program with an optimal quality according to a residual quantity of a recording medium and a method therefor. The video recording apparatus detects the residual quantity of the recording medium and a running time of the television program to be recorded on the recording medium, to determine an optimal image compression ratio. Then, the video recording apparatus records the television program based on the determined optimal image compression ratio, making the best use of the residual quantity of the recording medium.

摘要： A radio receiver for receiving a selected digital TV signal uses final intermediate frequency signals the carrier frequencies of which are multiples of symbol rate. The radio receiver has a match filter receptive of rectified samples of digitized intermediate-frequency signal and responsive to the amplitude of the intermediate-frequency carrier being modulated in accordance with the field synchronization code group to generate a pulsed response to the beginning of each data field. This pulsed response is used to determine when data segment synchronization information should occur, so its detection is more certain to be accurate and data segment synchronization is more rapidly determined. Symbol synchronization is rapidly inferred from the field synchronization and data segment synchronization, so that the samples in each data line can be counted. The complex carrier frequencies of the final intermediate frequency signals are generated in response to the samples per data line count, for implementing synchronous detection to baseband. The adjustment of the carrier frequency of the final intermediate frequency signal to be a prescribed multiple of symbol rate is done in response to an automatic-frequency-and-phase-control signal developed from the synchronous detection results.

摘要： A frequency-multiplexed video signal is generated in which a color-under signal and a second under signal are linearly combined with at least partially overlapping frequency spectra to form a composite under signal for an FM luma signal. The frequency-multiplexed video signal is suited for recording on magnetic tape using helical scanning methods and for being played back from the magnetic tape using helical scanning methods. The second under signal is generated in such way that line-comb filtering can be used during playback to separate color-under signal and second under signal each from the composite signal despite their frequency spectra being at least partially overlapping in the composite signal.

摘要： Apparatus is disclosed for processing video information which is reproduced from a magnetic recording medium in a video cassette recorder. The luminance portion of the video signal, which is "folded" about a sampling frequency carrier before recording on magnetic tape, is unfolded after being read from the magnetic tape to restore the bandwidth of the signal, and is applied in parallel through horizontal and vertical comb filters. The combined output of the horizontal comb filter and the vertical comb filter may include incompletely cancelled horizontal and vertical components of the folding frequency and sidebands due to the effects of picture contents. An edge detector receptive to the unfolded video signal responds to an encountered brightness edge, and generates a signal which varies the proportions of the video outputs of the horizontal and vertical comb filters in the combined output.
