  • Patent number: 6587948
    Abstract: A recording method and a recording apparatus whereby digital data is recorded onto a disc as run-length limited code used for modulating marks or spaces on the disc and, at the same time, the recorded digital data is encrypted by using key data which is also recorded onto the same disc by varying the shape of marks or spaces with timing having no effect on the edges of the marks or the spaces. A playback method and a playback apparatus reproduces the digital data and the key data recorded on the disc by the recording method and/or the recording apparatus from the disc with the key data used for decrypting the reproduced digital data.

  • Patent number: 6492927
    Abstract: A plurality of data items are received in each frame period, and a digital signal processor (DSP) checks a flag corresponding to each data item in each frame period before the DSP applies processing to the received data. When the checked flag allows the corresponding data item to be processed, the process is performed. When the execution of the process is finished, the flag is reset. When all the flags are reset, the DSP enters a sleep state.
