摘要： A processing unit performs a method including controlling a reading-out of data from a first storage medium at a predetermined read-out data rate to produce inputted data, and controlling a compression of the inputted data to produce first compressed data of a first compressed format. The method includes controlling a storage of the first compressed data in a second storage medium at a faster writing data rate than the predetermined read-out data rate, controlling a reading-out of second compressed data of a second compressed format from the second storage medium, and controlling a decompression of the second compressed data to produce decompressed data. The method also includes controlling simultaneously the storage of the first compressed data in the second storage medium, the reading-out of the second compressed data from the second storage medium, and audibly reproducing the decompressed data. The first compressed format is different from the second compressed format.

摘要： High-rate writing of data recorded on a CD into a hard disk drive (HDD) is performed while reproducing data read out of the CD at the standard bit rate prescribed for the CD. PCM data corresponding to a playback time of 10 seconds, for example, is read out of a CD and stored in a memory. The data is read out of the memory at appropriate timing and outputted after being converted into an analog audio signal by a D/A converter. In parallel, data for writing is read out of the CD in succession to reading of the data for playback and stored in the memory. The data read out of the memory is coded and compressed by an encoder and then stored in the memory. The compressed data is read out of the memory in units of a certain amount suitable for writing in an HDD and then written in the HDD. When the data stored in the memory for playback has become smaller than a predetermined amount, an interrupt is generated during the writing process with the processing, which is given top priority, so that a next set of playback data is read out of the CD and stored in the memory.

摘要翻译： 在CD上规定的标准比特率再现从CD读出的数据时，将记录在CD上的数据高速写入硬盘驱动器（HDD）。 例如，对应于10秒的播放时间的PCM数据从CD读出并存储在存储器中。 数据以适当的定时从存储器中读出，并通过D / A转换器转换成模拟音频信号后输出。 并行地，用于写入的数据被连续地从CD读出以读取用于回放并存储在存储器中的数据。 从存储器读出的数据由编码器编码和压缩，然后存储在存储器中。 压缩数据以适合写入HDD的一定量的单位从存储器中读出，然后写入HDD。 当存储在用于回放的存储器中的数据已经变得小于预定量时，在写入处理期间产生中断，其中处理被给予最高优先级，使得从CD读出下一组重放数据， 存储在内存中。

摘要： An information-processing apparatus includes a processing unit that compresses inputted data to produce compressed data of a first compressed format. The information-processing apparatus also includes a storage unit that stores the compressed data in a storage medium. The processing unit decompresses data, stored in the storage medium, of a second compressed format to produce decompressed data. Further, the processing unit controls the storage unit to store the compressed data of the first compressed format in the storage medium while the processing unit simultaneously decompresses the data, stored in the storage medium, of the second compressed format and reproduces the decompressed data. The first compressed format is different than the second compressed format.

摘要： The present invention relates to an information apparatus and method suitable for use in upgrading control programs readily by a user. In step S501, a storage area to store an upgraded firmware is determined. In step S502, the upgraded firmware is provided. In step 503, the provided firmware is decrypted and re-encrypted. In step S504, re-encrypted firmware is written into the storage area determined in step S501. In step S505, a maximum marker is detected. In step S506, a value obtained by adding 1 to the maximum marker provides the marker corresponding to the storage area in which the firmware was stored in step S504. The present invention is applicable to, for example, an audio data server.
