Description: LibMPEG3 decodes several MPEG standards into uncompressed data suitable for editing and playback.
libmpeg3 currently decodes:
MPEG-2 video
MPEG-1 video
mp3 audio
mp2 audio
ac3 audio
MPEG-2 transport streams
MPEG-2 program streams
MPEG-1 program streams
IFO files
The video output can be in many different color models and frame sizes. The audio output can be in twos compliment or floating point. Frame accurate seeking, normally impossible in transport streams, is possible in libmpeg3 through the use of a table of contents. MPEG-2 video in YUV-422 colorspace is decodable. Digital TV broadcasts and DVD s can be edited using libmpeg3. Libmpeg3 takes what is normally a last mile distribution format and makes it editable.
Because of these and other features libmpeg3 is not intended for consumer applications but serves users who are interested in high quality editing and footage acquisition.

Description: The purpose of this application note is to describe the main elements of
an RS-422 and RS-485 system. This application note attempts to cover
enough technical details so that the system designer will have considered all
the important aspects in his data system design. Since both RS-422 and RS-
485 are data transmission systems that use balanced differential signals, it is
appropriate to discuss both systems in the same application note. Throughout
this application note the generic terms of RS-422 and RS-485 will be used to
represent the EIA/TIA-422 and EIA/TIA-485 Standards.-The purpose of this application note is to d escribe the main elements of an RS-422 and RS-48 5 system.

Description: 本程序采用异步方式，除了可作为一般串口调试程序（232方式，或485、422主）来使用，也可以作为485、422设备（从模式）进行调试，当选中（是否比较）复选框后，收到上位机请求时，如果和比较区的内容一致，则自动回复发送区的内容，未选择比较框将按照设定的发送周期定时回复。
参数设定：
发送周期：单位毫秒。用于设定两次自动发送的时间间隔。
延迟接收时间：单位毫秒。推荐仅用于485方式，因为485为半双工模式，所以不能同时进行收发，此时间间隔在自动发送时必需小于上面设定的发送周期。
限制：发送接收必须为同一进制（十六进制或ASCII等）

Description: 在工业生产和科学技术研究的各行业中，常常利用PC或工控机对各种数据进行采集。这其中有很多地方需要对各种数据进行采集，如液位、温度、压力、频率等。现在常用的采集方式是通过数据采集板卡，常用的有A/D卡以及422、485等总线板卡。采用板卡不仅安装麻烦、易受机箱内环境的干扰，而且由于受计算机插槽数量和地址、中断资源的限制，不可能挂接很多设备。而通用串行总线（Universal Aerial Bus，简称USB）的出现，很好地解决了以上这些冲突，很容易就能实现低成本、高可靠性、多点的数据采集。
