编码信号

A method for variable length coding an ordered series of digital signals, e.g., of quantized transform coefficients of a block of image data with a most likely-to-occur amplitude, e.g., 0, and at least one other amplitude, e.g., 1, to form a set of codewords.

本发明提供了一种对数字信号例如具有最可能出现的幅度(例如0和至少一个其它幅度(例如1)的图像数据块的量化变换系数的有序系列进行可变长度编码以形成一组码字的方法。

It has been proved that Lifting Scheme can realize all the first generation wavelet transforms. On the basis of research of Lifting wavelet technology and DSP technology, this paper empolders a sort of long-distance monitoring system.

本文是在对提升小波技术和DSP技术进行研究的基础上开发的一种远程监测系统，本系统是数字信号处理技术、图像压缩编码技术和网络通信技术相结合的产物。

Pro Logic — manually selecting Pro Logic may be needed when listening to a conventional digital signal, as from a laserdisc player, which does not have an identifying "flag" to indicate whether it is simply stereo, or Dolby Surround encoded.

定向逻辑——在欣赏普通数字信号，如 CD 影碟机时，由于其本身没有鲜明的&旗帜&来表明它到底是立体声音频规格的还是 Dolby Surround 编码的，所以可能需要手动选择 Pro Logic 。

Most of the vocoders, such as CELP, MELP are based on this model, which make it better for the applications when less storage space is needed.

语音信号的分析合成采用线性预测模型，线性预测模型是一种在技术上比较成熟的语音模型，大部分的语音编码器如CELP、MELP 等都是基于此模型，所以在需要减小语音库的存贮空间时有较大的优势。

The videodisk, in the form of Laser Vision, serves as the output of motion pictures and audio. The data are stored in an analog-coded format on the disks; the reproduced data meet the highest quality requirements.

以激光视觉形式的视频和音频的输出，数据以模拟编码形式存在盘上，再生的信号能符合最高的质量要求。

It can simultaneously mix up to 6 encoded audio bitstreams plus a soundcard input signal.

它可以同时混合多达6个编码音频位流外加一个声卡输入信号。

In order to elucidate the relationship between the structural features of leginsulin gene in legume plants and their phylogenetic significance,we have cloned the cDNA sequence of leginsulin gene from radicles of broad bean via RT-PCR techniques according to the leginsulin gene sequence we previously obtained from soybean.The cloned cDNA encoded for a precursor protein consisting of the signal peptide,mature leginsulin and an additional 45 amino acids of another polypeptide.

为探明豆科植物中豆类胰岛素基因的结构特征与进化关系，在已获得大豆豆类胰岛素基因的基础上，以蚕豆种子胚根mRNA为材料，采用RT-PCR技术，克隆了蚕豆豆类胰岛素基因的cDNA序列，编码的前体多肽包括信号肽、成熟型豆类胰岛素及另一多肽的45个氨基酸残基。

One transmission cell to another while maintaining the DVB-H service.· For a number of reception scenarios; indoor, outdoor, pedestrian and inside amoving vehicle, the transmission system shall offer sufficient flexibility and scalability to allow the reception of DVB-H services at various speeds, whilstoptimizing transmitter coverage.· As services are expected to be delivered in environments that suffer high levels of man-made noise, the transmission system shall offer the means to mitigate their effects on the performance of the receiving terminal.· As DVB-H aims to provide a generic way to serve handheld terminals in various part of the world, the transmission system shall offer the flexibility to be used in various transmission bands and channel bandwidths.

因此DVB-H采用分时方式的资料传送形式，把原本通道频宽是由其它节目共同分配享有的，现在只可以让某一个节目使用全部的频宽所以让节目传送的位元率提高了，相对的减少传送的时间，但跟DVB-T一样在单位时间内所传送的资料是一样多的，由於DVB-H采用分时多工的方式传送资料所以接收器只在该节目传送的时间内接收该笔资料，而其它时间则不接收然后在等一个单位时间内，该节目的资料再传送时在接收，如此开关开关达到收到整部节目的资料，并大量的减少持续接收节目所消耗的功率，接下来由於DVB-H采用4K正交分频多工编码的方式，虽然涵盖的范围没有DVB-T大但对高速移动的时候接收信号时的效果会比较好。

Particular designs for joint structure are presented. The integrative design method of joint structure and angle coders is adopted so that the mechanical structure is compact and the cost is lower. In order to lighten the swing of rotary axis of joint angle sensor, high-accuracy anglecontact ball bearing is selected.

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
