摘要： A scheme for management of uncertainty in control systems that require adaptation is described. The scheme removes as much uncertainty as possible at design time and manufacturing time by taking advantage of available compute resources in pre-computing a large set of robustness-performance tradeoff based model controllers at different operating conditions for different values of uncertainty parameters that occur in-use and in manufacturing. A group of control models, and corresponding model controllers with an uncertainty bound larger than the best-tuned controller, are generated. A subset of the model controllers is implemented in the system at manufacturing time based on characterization of the system. The subset of model controllers is switched at run time based on transient information received during operation of the system.

摘要： An embedded DRAM is incorporated inside a digital-versatile-disk (DVD) playback-controller integrated circuit. Data from the DVD optical disk is written to a data block in the embedded DRAM. Error correction is performed by reading the data block to generate syndromes and over-writing errors in the data block with corrections. Once the data block is corrected, it is copied or moved to a different area of the embedded memory, a host-buffer area. As the data block is moved, de-scrambling is performed to decrypt the data. The re-ordered data is stripped of overhead such as ECC bytes and written to the host-buffer area of the embedded DRAM. A checksum is generated as the data is moved, and the checksum is compared to a stored checksum to ensure that all errors were corrected. The data block in the host-buffer area is then transferred to a host. The embedded DRAM has a very wide data-access width of 16 bytes. The full width is used for writing data from the optical disk to the ECC data block buffer, and for reading data from the host-buffer area to the host. Narrower access widths are used by the error correction and de-scrambler blocks.

摘要翻译： 嵌入式DRAM集成在数字通用盘（DVD）播放控制器集成电路内。 来自DVD光盘的数据被写入嵌入式DRAM中的数据块。 通过读取数据块来执行错误校正，以在校正中产生校正子和数据块中的写入错误。 一旦数据块被纠正，它将被复制或移动到嵌入式存储器，主机 - 缓冲区域的不同区域。 当移动数据块时，执行去加扰来解密数据。 重新排序的数据被剥离诸如ECC字节的开销，并写入嵌入式DRAM的主机缓冲区。 随着数据移动，生成校验和，并将校验和与存储的校验和进行比较，以确保所有错误得到纠正。 然后将主机缓冲区中的数据块传送到主机。 嵌入式DRAM具有非常宽的16字节的数据访问宽度。 全宽用于将数据从光盘写入ECC数据块缓冲区，并将数据从主机缓冲区读取到主机。 较窄的访问宽度由纠错和解扰器块使用。

摘要： A time counting device, a cache memory and a copy control circuit are added to a conventional disk drive so that recorded information is copied periodically and automatically. Alternatively, a cache memory, a copy control circuit, a reference control circuit, a first time counting device and a second time counting device are added to the conventional disk drive so that information which remains recorded for a predetermined period of time after its last recording date is automatically copied. According to another embodiment, a reference signal is recorded in advance and a reproduced output is periodically measured. If the reproduced output is lower than a reference value, recorded information is automatically copied. According to yet another embodiment, the temperature in the disk drive is measured by a thermometer 18, and if the temperature is higher than a reference value, information is automatically copied at shorter intervals than when the temperature is less than the reference value. Other embodiments are also disclosed with the aim of ensuring that information recorded on a magnetic media can always be reproduced reliably, even in the case of high density recording.

摘要： System for recording/writing on a recording medium in which there are distributed, on the tracks, groups (G0) of tracks with positive continuous components and groups (G1) of tracks with negative continuous components. In reading, the values of the different signals are integrated for each track. Then, on the one hand, a first addition circuit S1 adds up the results of integration of the first tracks of each group of tracks and, secondly, a second addition circuit S2 adds up the results of integration of the last tracks of each group of tracks. A comparison circuit (CD) compares the results of additions of the two addition circuits to correct the track-following operation.

摘要： Tracking control apparatus and method for a digital/analog recording/playback system which is capable of recording and playing back a digital video signal as well as an analog video signal compatible with an existing VHS system. A tracking signal is recorded by first and second heads for the recording and playback of an analog video signal, and a digital video signal is recorded by third and fourth heads for the recording and playback of the digital video signal. The recorded tracking signal is played back by the first and second heads and the recorded digital video signal is played back by the third and fourth heads. The digital video signal is recorded on a portion of a tape wound at an angle of 180.degree. with respect to a head drum and the tracking signal is recorded on upper and lower 5.degree. portions adjoining the 180.degree.-wound portion of the tape. Therefore, a loss of the digital video signal can be avoided. This has the effect of obtaining a high picture quality.

摘要： A karaoke apparatus operates in response to a song request for sounding an automatic accompaniment mixed with a singing voice to produce a karaoke performance involving an additional effect. The karaoke apparatus is supplied with a composite song data containing an accompaniment event data and an additional effect event data. A multimedia sequencer time-sequentially processes the supplied composite song data to synchronously feed a train of the accompaniment event data and another train of the additional effect event data in parallel manner with one another. A tone generator operates based on the fed accompaniment event data for generating an automatic accompaniment so as to produce a karaoke performance. An additional effect equipment is controlled by the fed additional effect event data for imparting an additional effect to the karaoke performance in matching with time-sequential progression thereof.

摘要： An analog reproduced output can be processed by a digital system circuit in a digital and analog data processing apparatus. An analog output reproduced from a medium on which analog signals are recorded is converted into digital signals by an (A/D) analog to digital converter of a digital recording and reproducing system. These signals are divided signals corresponding to predetermined frequency bands by sub-band filters. The signals are input to a (DSP) digital signal processing section and an (ECC) error correction coding section. An frequency characteristic adjustment operation and an interpolation operation are performed digitally under the control of a controller. Then, for example, the signals are converted by a (D/A) digital to analog converter and output.

摘要： In a digital signal reproducing apparatus various adjustment jobs and measurement jobs can be automatically executed by a simple operation by providing a clock generator, an external waveform equalizer, an error detector, an edge detection circuit, and a DC following circuit in addition to a waveform equalizer by which a reproduced analog signal waveform is processed and then converted to a digital signal. The digital signal is equalized by a digital filter and sampled and the digital signal and extracted clocks are supplied. The reproducing level and the equalizer coefficients can be automatically adjusted and an error rate can be automatically measured. A pulse width modulation or bias recording can be automatically determined and a recording current can be automatically adjusted by the system and the inclination of magnetic heads and the distance between the heads can also be automatically measured.
