本文研究了HDTV视频解码的一些关键技术，如输入缓冲器的控制、错误处理等。

A system for playing the digital video frequency with a changable playing back speed comprises: an acquiring module for acquiring the coded picture from the data memorizer; and a distributor module for selectively deleting the coded picture from the input high-speed buffer.

一种以变化的回放速度播放数字视频的系统可以包括：获取器模块，配置用于从数据存储器中获取编码后的画面；以及分配器模块，配置用于从输入高速缓冲器中选择性地删除编码后的画面。

Signal processing device for providing multiple output images by processing input images of an interlaced video signal, comprising a temporal interpolator circuit (18) and a memory buffer (26, 27) connected to the temporal interpolator circuit.

一种通过处理隔行视频信号的输入图像来提供多个输出图像的信号处理装置，它包括时间内插器电路(18)和连接到该时间内插器电路的存储缓冲器(26，27)。

One buffer points to the present video frame, which is sent to the display at a certain refresh rate.

一个缓冲器区指向目前的视频帧，该帧被以一定的刷新速率送到显示器上。

The working of input buffer of ideal and practical decoders are analyzed and based on our HDTV real-time video decoder structure, the buffer control strategy and system improvement methods are proposed and implemented.

分析了理想情况和实际情况下输入缓冲器的工作，针对HDTV实时视频解码系统，提出并实现了缓冲器控制策略和系统结构改进措施。

Depending on the external connections, the internal resistor network may be used to provide either a fixed gain of +2 video buffer or a gain of +1 or C1 voltage buffer.

根据不同的外部连接，内部电阻网络可以用来提供任何视频缓冲器的2 +1或1或C1的电压缓冲器增益固定增益。

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。

Switching between the video modes is realized by reassigning connections of tasks (20, 22, 24, 26) to respective ones of the communication buffers (16a-d), keeping previous data in the reassigned FIFO communication buffers (16a-d).

视频模式的切换是通过重新分配任务(20，22，24，26)到通信缓冲器(16a-d)中各个缓冲器的连接、将之前的数据保持在重新分配的FIFO通信缓冲器(16a-d)中来实现的。

Current products include a wide array of video frame and line buffers, format converters and highly integrated video processors.

目前的产品包括各式各样的视频帧和线路缓冲器，格式转换器和高度集成的视频处理器。

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。
