The only mandatory power - consumption regulation in the u . s . that affects non - government consumers is the california energy commission ' s ( cec ) efficiency requirements for external power supplies and consumer audio and video equipment sold in california 在美国可以影响非官方消费者的唯一强制性能耗法规是加州能源委员会( cec )制定的加州所卖外部电源和消费音频及视频设备能效标准。
For the third type , the blood ' s speed is very fast in a frame and maybe very slow in the next frame . it is difficult to measure the velocity using a standard video system but can be measured with high - speed video camera system [ 17 , 42 , 43 ] 第三类微血管内血液流动特性是时快时慢，很难在标准视频设备下测量出来，但如果在高速采集卡下的视频图象和第一类一样时，可以用第一类相同的方法测量出来。

In this paper , interface signal of the digital televisions set - top - box is analyzed and studied , it is of significance to high quality transmission , effective scheme of hardware system and exerting the most efficiency of the audio and video equipment of digital television signal 本文对其接口信号进行的分析比较研究，对于数字电视信号的高质量传输，硬件设备的合理配置以及充分发挥音视频设备的最大效能，具有重要的实践意义。
On swithching technique , there are wired standards as homepna and ieee 1394 , and wireless standards such as homerf , bluetooth . about the high level interconnect , there are havi for home video and audio connecting and control , sun ' s jini , osgi , and upnp from microsoft 在物理层接入技术上，有homepna 、 ieee1394 ， homerf 、 bluetooth等，在高层应用互联上，有用于家居网络中音频、视频设备的互联和控制方面的havi标准，有由sun公司提出的jini 。
The development of multimedia systems brings a major influence in the area of image and video encoding . the interactivity and integration of video data with computer , cellular and television systems becomes a new problem of research worldwide . as the content representation formats increase progressively , interoperability between different systems is becoming more and more important 通信、计算机和互联网的结合为视频应用带来了前所未有的机遇但也对压缩视频的传输提出了新的挑战。多种视频压缩标准的存在,导致视频设备间的兼容问题,而视频转码是有效解决这种兼容问题的一种技术。
Modern embedded system has great computing capacity and been used in most aspects of human lives : pda , mobile phone , set top box , networks , computer of car , security systems , medical instruments , audio / video , information appliance , etc . most embedded systems have their own os 现今的嵌入式系统已具有非常强的计算功能，广泛的应用到了人们的日常生活中： pda 、手机、机顶盒、网络设备、车载电脑、安全系统、医疗仪器、音视频设备、信息家电等等。通常嵌入式系统需要嵌入式os的支持。
Adopt the ds18b20 ' s figure temperature sensor , take the online measure to the key eq uipment of the system ; as to the video signal in the monitoring system , since the fact that video wire is tiny , and the connector is great , especially to those relative and removable video signal , the video wire is easy to break down , such as short circuit and so on , along with the video device is over a long period of time being in the circular telegram running state , also easily running into trouble , hence , valid means to be take adopt to the video signal 本故障分析仪采用了ds18b20数字温度传感器，对关键设备的机温进行实时在线监测；对于监控系统中的视频信号，由于其线路长、线径细、转接头较多，尤其是那些可旋转、移动的视频信号，易发生视频线断线、短路等情况，再加上视频设备是长期处于通电运行状态，也易发生故障情况。因此应采用有效的方式对视频信号进行监控。
