查询词典 buffer delay

So, depending on the band- width required to serve the video and the bandwidth available, it creates a buffer to hold enough video so that it can start playing back the video while it is downloading video to the buffer in the background.

它决定于播放视频需要的带宽和可以带宽，它创建一个缓冲区来保持足够的视频数据，因此它可以在后台线程下载视频到缓冲区的同时播放视频内容。

Why audio buffer needs only one stage while video buffer needs two stages for amplification?

为何音频电路仅需要单级放大电路，而影像电路必须两级反向。

We discuss the effect that disk scheduling algorithms have on the disk bandwidth and buffer that is needed in retrieval of video, present algorithms for buffer management, disk scheduling and admission control, and probe into the technology for the storage of scalable compressed video data.

为了实现视频数据的优化存储与回取，本文对MPEG流的结构及传输特性进行了讨论，分析了现有磁盘系统的读取过程和延时特性，建立了用于对连续媒体回取过程进行分析的磁盘传输延迟模型。

Sometimes a video overlay buffer is premultiplied by alpha or premapped via a lookup table, in which case it's referred to as a "shaped" video buffer.

有时一个视频叠图缓冲区要预先乘以 a ，或者预先借助速查表进行映射，在这种情况下，它被称为一个"经过整形的"视频缓冲区。

The packet disassembly circuit inserts the portion into an absolute location of the buffer, the position identifier determining the location, the portion thereby synchronized with adjacent portions of the stream of digital audio/video data in the buffer to compensate for the variable periods of transmission time.

数据包拆卸电路把该部分插入到缓冲器的绝对位置上，位置标识符确定该位置，从而使该部分与缓冲器中的数字音频／视频数据的数据流的相邻部分同步，以补偿可变的传送时间周期。

The coding device for DVD system and other record systems includes audio and video coder to convert the input audio and video data into audio and video data stream; system coder to convert the audio and video data stream into audio and video data stream of, say, MPEG format; audio and video data stream buffer before the system coder to store audio and video data stream generated during one set period by the audio and video coder; and buffer downstream the system coder with relatively low capacity and capable of performing the record operation of pre-trigger.

提供了在DVD系统等记录系统中使用的编码设备。该编码设备包括分别把输入音频和视频数据转换成音频和视频数据流的音频和视频编码器、把音频和视频数据流转换成例如MPEG格式的音频／视频数据流的系统编码器。还包括系统编码器上游的音频和视频流缓冲器，它们分别存储音频和视频编码器在一段预选的时间内产生的音频和视频数据流，从而使系统编码器下游的缓冲器的容量较小并有效地进行预触发器记录操作。

Now that we have the mode set up, we need to create the drawing surfaces. To do good animation, we need to double-buffer, so we're going to set up the flags so that it creates one back buffer (you can make as many as you have VRAM for, but two should be sufficient unless you're doing stereo imaging... but that's a whole other topic). This call is similar to may DirectX calls that have lots of fields.

现在我们已经进行完了模式设置，我们还需要双缓冲来显示效果良好的动画，可以通过设置一些标志来创建一个后缓冲(你可以在你的显示内存足够情况下创建任意多个，但是一般二个应该足够了，除非你要做立体图形实时绘演，可那完全是另一个问题了)。

The high speed multiplex first-in first-out storage structure includes at least two memory unit arrays, one integrated decoder circuit between the two memory unit arrays, one write-in control circuit over the decoder circuit, one read-out control circuit below the decoder circuit, two data buffers on the two memory unit arrays separately, two multiplex circuits and two output circuits below the two memory unit arrays separately, and one write-1 clock buffer and one read-out clock buffer over and below the decoder circuit separtely.

一种高速多路先进先出存储器结构，包括一至少两存储单元阵列、一位于至少两存储单元阵列中间的整体解码电路、分别位于整体解码电路的上下的一写入控制电路及一读出控制电路、分别位于至少两存储单元阵列上的两数据输入缓冲器以及依序位于两存储单元阵列下的两多工电路及两输出电路，在整体解码电路的上下分别设置一写入时钟缓冲器及一读出时钟缓冲器。

Notice that the Z buffer is enabled for this sample. It might seem to make more sense to disable the Z-buffer, however, when tiling bitmaps inside a program (for dialog boxes, target reticules, etc.) it is a great comfort to be able to set a z value, rather than resort the render list.

可以选择是否打开 Z Buffer属性，这样在绘制如tile这样（译注：如游戏地图与精灵的关系）场景的时候，通过z值，可以很清楚地表现出位图之间的层次关系（译注：如树应该挡住人，而人应该挡住草地……），当然这会有一定开销。

It was helpful to extract enzyme by using homogenate in citrate-phosphate buffer; The enzyme activity extracted from pH5.6 buffer is higher than that of pH5.8.The loss of enzyme activity of this zymin is better, but easily used in manufacture.

丙酮粉提取法会引起回收酶活性较大损失，其总酶活仅是缓冲液匀浆法和浸提法的1/5、1/7，但酶制剂本身的酶活性较好，使用方便，有利于工业化生产应用。

Researches reveal that students who suffer from corporal punishment tend to resort to violence in their future life.

研究表明遭受过肉体惩罚的孩子倾向于在他们今后的人生中使用暴力。

Total sugar of sarcocarp and chlorophyll of pericarp increased firstly, and then decreased afterward along with altitude; Titratable acidity, ascorbicacid and anthocyanin of pericarp were increased along with altitude; The content of protein increased firstly and decreased afterward along with altitude; Carotenoid of pericarp were decreased along with altitude.

果肉总糖和果皮叶绿素含量随海拔高度升高先升高后降低；可滴定酸、维生素C和果皮花青苷含量均随海拔升高而升高；蛋白质在1720m处最大，1420m处最小；果皮类胡萝卜素随海拔升高而降低。
