    摘要： A source data stream is distributed to two or more compression paths that provide a corresponding number of compressed data streams that are concurrently encoded onto a recording medium as a set of media tracks. In one embodiment, buffer space within each compression path is monitored and the source data stream is directed to a ‘starved’ compression path. Metadata is inserted into the compressed data streams to facilitate reconstruction of the source data stream from the compressed data streams. The source data stream may be reconstructed by concurrently decoding the media tracks, decompressing the compressed data streams to a corresponding set of decompressed data streams, and merging the decompressed streams into an output data stream as directed by the metadata. The present invention overcomes the bottlenecks and other issues previously associated with context-based compression within digital media recording systems.

    摘要： Disclosed is an optical disc drive that can resume to record data consecutively from the position just after the data recording operation was suspended without overwriting when recording data onto an optical disc. The optical disc drive includes a rotational driving mechanism for rotating the loaded optical disc; an optical pick-up having emitting means that emits a laser beam for recording data to the optical disc; a laser control circuit for controlling an output of the laser beam; a drive circuit for driving the emitting means; and voltage hold means provided between the laser control circuit and the drive circuit for holding a voltage to be input to the drive circuit at a voltage value at which an output of the laser beam becomes an optimum level for recording data onto the optical disc. The voltage hold means holds the voltage to be input to the drive circuit to the voltage value at which the output of the laser beam becomes the optimum level for recording.

    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： An apparatus records main information and sub information onto an information recording medium, which has a main recording area and a sub recording area. The apparatus is provided with an receiving device that receives the main information input from the external source; an accumulating device that accumulates the main information received by the receiving device; a recording device that records the main information and the sub information to the main recording area and the sub recording area, respectively; and a controller that determines whether or not an amount of the main information accumulated in the accumulating device is smaller than a predetermined amount, and that controls the recording device. In the apparatus, the recording device records the sub information to the sub recording area under a control of the controller if the controller determines that the amount of the main information accumulated in the accumulating device is smaller than the predetermined amount, and the recording device records the main information to the main recording area under a control of the controller if the controller determines that the amount of the main information accumulated in the accumulating device is not smaller than the predetermined amount.

    摘要： An audio decoder is described which supports simple sound-effect generation. The audio decoder includes a direct access pulse code modulation (PCM) first-in-first-out buffer (FIFO) to support simple sound effect generation. In one embodiment, the audio decoder additionally includes an input buffer, a decoding module, and an output interface. The input buffer buffers incoming data frames for the decoding module to retrieve and convert to a sequence of decoded audio samples. The FIFO is configured to receive and buffer audio sound effect samples from a control component external to the audio decoder. The output interface is configurable to retrieve decoded audio samples from the decoding module and audio sound effect samples from the FIFO. Any retrieved audio sound effect samples are included in a digital audio output signal provided by the output interface. The digital audio output signal may be provided directly to a digital-to-analog converter for sound reproduction. The availability of the FIFO for direct writing of audio samples by control components of the system provides desirable system features at negligible cost. A control component of the system is provided with the ability to easily generate test tones, to produce audio feedback to assist in user-control manipulation, and to support new system features such as alarm clocks and timers.
