摘要： The present invention has an objective of providing an optical disk having a high resolution picture and a system for reproducing data on the optical disk, which are compatible with a conventional system for reproducing an ordinary resolution picture. A high resolution signal is divided into a main signal and a sub signal by picture division means and MPEG-encoded. The main signal and the sub signal are divided into frames each having 1 GOP or more. The resultant first interleave block 54 and second interleave block 55 are recorded alternately on an optical disk. A high resolution reproduction apparatus reproduced both the first and second interleave blocks, so that a high resolution picture is obtained. A non-high resolution reproduction apparatus reproduces only the first or second interleave block, so that an ordinary resolution picture.

摘要： An optical disc apparatus includes a pause circuit for pausing data encoders upon receiving a pause signal so that a write operation may be paused without writing dummy data, thereby maintaining data succession. The optical disc apparatus also includes a circuit for accurately determining a write start location by referring to previously written data. A processor generates a pause signal when the amount of data in the optical drive apparatus data buffer is low, and removes the pause signal when additional data from a host is received. The processor may also automatically reduce the write speed of the optical disc apparatus upon a pause condition, thereby preventing the necessity for excessive pausing.

摘要： A separation unit accepts a digital video and audio signal sent from outside in units of packets and separates the signal into video data and audio data. The audio data separated by this separation unit is written for each packet in an audio data buffer, from which the written audio data is consecutively read out. Moreover, a available capacity determination unit determines a available capacity in the audio data buffer. Based on a result of the determination by this available capacity determination unit, an oscillation frequency of a frequency variable oscillator and the reading at said audio data buffer are controlled.

摘要： A controller for controlling interruptions and restarts when writing data to a recording medium by emitting a laser beam against the recording medium. The controller prevents buffer underrun errors. The laser beam is emitted at a high power level when writing data on the recording medium and at a low power read level when reading data from the medium. The writing of data is interrupted when there is a possibility of a buffer underrun error. When restarting data writing from where the interruption occurred, the laser beam is shifted from the read level to the write level before reaching the location at which the interruption occurred. This guarantees that the laser beam has the required power level when writing is restarted.

摘要翻译： 控制器，用于通过向记录介质发射激光束来将数据写入记录介质时控制中断和重新启动。 控制器防止缓冲区欠载错误。 当从介质读取数据时，在记录介质上写入数据并且处于低功率读取级别时，激光束以高功率电平发射。 当存在缓冲区欠载错误的可能性时，写入数据会中断。 当从发生中断的地方重新启动数据写入时，激光束在到达发生中断的位置之前从读取电平转移到写入电平。 这确保了在重新启动写入时激光束具有所需的功率电平。
