数字数据

Computers work not only with numbers, but with alphanumeric data -names, words, stock numbers.

计算机工作不仅与数字，但字母数字数据的名称，文字，股票号码。

Alphanumeric Data Numbers, letters, and other characters

A method is provided for encoding and decoding a sequence of digital data, according to which a portion of the sequence of digital data corresponds to a data block that includes several data packets, at least two data packets per data block containing an identifier. The position of the data packet within the corresponding data block can be determined based on the identifier, and the data is encoded or decoded by taking into account the identifier.

本发明给出了一种用于对数字数据序列进行编码和解码的方法，其中该数字数据序列的一部分相当于一个数据块，其中该数据块包含多个数据包，其中每个数据块的至少两个数据包分别包含一个特征标记，其中根据该特征标记确定数据包在所属的数据块中的位置，以及其中在考虑该特征标记的情况下对数据进行编码或解码。

For digital communication systems, bandwidth describes the capacity of the system to transport digital data from one place to another.

对于数字通信系统，宽带叙述的能力运输系统的数字数据从一个地方到另一个地方。

With the technological development, more and more original data shall be acquired and processed and a large amount of intermediate data and result data will be produced in processing. Pure digital data have developed to multimedia data such as sound and image ones, so that there are more demands for advanced data management. Moreover, the system calls for higher integration degree even on-line real-time processing in many cases, and its integration with network and distributed processing need considering as well.

随着科学技术的发展，采集、处理的原始数据量越来越大，且在处理过程中将产生大量的中间数据和结果数据；数据已经从纯粹的数字数据发展到声音、图像等多媒体数据，对数据管理的要求越来越高；系统集成度越来越高，在许多场合要求联机实时处理，并需要考虑与网络的集成，进行分布处理。

The coding method includes the steps of representing respective digital data by digits of a predetermined same number, and coding the digital data represented by digits of the same number by a predetermined coding method from the uppermost significant digit sequence to the least significant digit sequence.

编码方法包括以下步骤：用相同的预定位数表示有关数字数据，以及使用预定编码方法自最高有效位序列至最低有效位序列将由相同位数表示的数字数据编码。

The system is also capable of transmitting alphanumeric data and converting this alphanumeric data to an audible form using a voice synthesizer.

系统还能发送字母数字数据，并将该字母数字数据转换成可用语言合成器收听的形式。

Finally, from the view point of recording high-fidelity data page, we optimized the storage system by using beam shaper in signal beam, and redesigning geometry to increase the uniformity of reference beam. In the final demonstration experiment, we encode 10KB Flash to four data pages, each including 512×512 bits. The data pages are 1:2 pixels matched. These four data pages were stored in a single point in a photopolymer media of Aprilis Corporation by using angle multiplexing method, and successfully retrieved.

根据我们设计的串行二进制数字数据与数据页之间的编解码方法，将一段10KB大小的Flash视频编码为4幅512×512幅面，1：2匹配的数据页，并成功的在美国Aprilis公司光致聚合物材料中完成了这4幅数据页的单点角度复用存储，再现数据页经过偏移补偿算法和PMSF算法处理后的平均原始误码率为2.4×10-4，这样低的误码率完全满足后期软解码的需要，并使得解码后的数据可以满足用户误码率的要求。

In a contactless IC card that performs envelope detection on an ASK-modulated carrier wave and demodulates the carrier wave to recover data piggybacked thereon, demodulation is suspended during periods where there is no possibility of a change of a data value (from data 0 to data 1, or from data 1 to data 0) in the digital data piggybacked on the carrier wave.

An image display apparatus includes a display having data holding function, a vertical drive circuit sequentially and selectively scanning matrix form display elements, and a horizontal drive circuit writing a voltage among binary voltage preliminarily assigned depending upon the digital data of the image signal. The horizontal drive circuit and the vertical drive circuit are operated for performing selective scan of respective display element for at least m times in one frame period. The vertical drive circuit is constituted of n number of sequence circuits and logic operation circuits for outputs of the sequence circuits, where n is smaller than m, a period from inputting to the sequence circuit to outputting from the final stage being less than or equal to half of one frame period, and at least one of the sequence circuits being used with selectively inputting a plurality of inputs.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
