Abstract

将PDA与无线调制解调器组合,以便能通过因特网和本地内部服务器遥控CE设备。

Description

带有通过因特网遥控的 无线调制解调器的个人数字助理
本发明特别涉及消费电子(CE)设备的遥控。
遥控器是广为人知的。例子是皇家菲利普电子公司(Royal PhilipsElectronics)制造的Pronto。Pronto是一种所谓的通用可编程遥控器。用它能存储几乎任何现有消费电子(CE)设备的IR码。Pronto有一个有触摸屏功能的LCD作为用户界面。Pronto的控制功能能全部由用户自己定制。Pronto用红外(IR)线与相近的CE设备通信。
本发明把CE范围内的“遥控”的概念进一步拓展。发明人提出向用户提供不管要被控制的设备与用户之间的距离多远的完全遥控。发明人也提出在遥控器与要被控制的设备之间的双向通信。
为此，本发明提供带有手持式计算设备(例如带有用户界面的PDA(个人数字助理))和与手持式设备相连的无线调制解调器的信息处理系统。无线调制解调器使得能通过诸如因特网的数据网络与服务器通信。控制网络连接在服务器与可控制的设备之间。手持式设备现在能通过因特网和服务器作为设备的无线遥控器。系统可包含一个摄像机，摄像机与硬件和软件一起生成格式化的静止图象，供在手持式设备上显示。用户现在能指令通过因特网从服务器检索静止图象。这个应用例如起安全系统的作用，使远程用户能监视其入口处，或者以远程(或后退(fall-back))婴儿照料的方式监视小孩。因特网无所不在，保障用户随时能使用设备，由此使得能扩展移动用户的控制范围和监视能力。
本文采用下列专利文件作为参考：
-美国序列号60/156,087(律师卷宗号PHA23，783P)，申请日1999年9月24日，申请人Martin Freeman和Bonghan Cho，名称“遥控启动控制配置的检索”。该文件涉及一种可编程的遥控器，它能启动从遥控器外部的存储设备中检索控制设置。该遥控器包含用于存储所检索控制设置的存储区，显示代表该设置的图标的显示器和根据所显示图标输入选择的触感屏。存储设备是CE装置的部件。通过在装置本身中存储或备份特定装置的控制设置，使遥控器真正能被统一地编程。
-美国序列号09/160,490(律师卷宗号PHA23，500)，申请日1998年9月25日，申请人Adrian Turner、Simon Pearce、David Eves和Allan Timms，名称“基于用户简档的因特网使能设备的定制升级”；和
-美国序列号60/160,490(律师卷宗号PHA23，527)，申请日1998年11月10日，申请人Eugene Shteyn，名称“家庭网络协作方面的升级”。上述两个文件涉及一种服务器系统，该系统保存能上网的消费电子设备的特定最终用户的用户设置预置文件和这类设备的新的技术特点的数据库。如果预置文件与某新技术特点有匹配，并且用户表明过愿意接收关于升级或销售产品的信息，用户就通过因特网得到关于获得该特点的选择的通知。检测用户的各个设备之间的最佳协同作用，以便通知用户关于使用或扩展其设备的其它可能性。
本发明是通过举例并结合附图说明的，其中图1是本发明中的系统的框图。
下面在两个例子的范围内解释本发明。第一个例子是用遥控器通过因特网开关电灯。第二个例子涉及从内部服务器(home server)检索图象。
图1是本发明的系统100的框图。系统100包含手持式设备102，诸如个人数字助理(PDA)(例如3COM制造的PalmIIIx或基于WindowsCE的手持式设备)，它通过无线调制解调器104与数据网络106(例如因特网)连接。调制解调器104例如是Minstrel或Ricochet。由Novatel Wireles s销售的Minstrel是用于PDA的双向无线调制解调器，能让用户浏览网页和接收电子邮件，等等。更广义上说，Minstrel或Ricochet一类的无线调制解调器提供手持式设备能被(在通量、延迟和覆盖面的限制范围内)用因特网通信的任何类型的应用使用的IP地址。Minstrel使用由蜂窝服务提供商支持的称作蜂窝数字包数据(CDPD)的技术。网上冲浪受到19.2kbps的CDPD速度封顶的限制。Metricom的Ricochet有在28.8Kbps范围内的连接速率，但是只在三个大城市中心(旧金山湾区、西雅图和华盛顿)受到支持。注意到本发明的系统中的遥控功能不需要高数据速率。所通信的信息的大小有限。本例中的数据速率大约是9，600波特。系统100进一步有服务器108、X-10控制器110、X-10开关模块112和灯114。X-10是一种用于电设备的控制的通信协议。该协议是为在标准家用线路上通信的X-10发射机与X-10接收机之间的通信而设计的。X-10在这里是作为例子提起的。不使用电源线的替代性控制机构是可行的，诸如CEBus、I2C、IR(通过IR点火器)等等。开关112在控制器110的控制下将灯114连接到主电源116。控制器110又从服务器108得到其控制输入。
PDA102有具有触感屏或图形输入板功能的显示器118和客户应用程序120。客户应用程序120控制显示器118上软按钮的生成。假设应用程序120在PDA102上启动。当用户启动显示器118上的ON(开)按钮时，应用程序120用无线调制解调器104通过因特网106向服务器108发送命令。
服务器108在本例中包含运行Apache万维网服务器122的PC硬件。Apache是一种公共域万维网服务器。它的最初版本是1995年在NCSAhttpd万维网服务器的基础上开发的。名称“Apache”源自它是由现有的NCSA程序码加上各种修补程序(patches)而开发出来的这个事实。因此，它被称作拼凑服务器(a patchy server)，于是有了Apatche服务器这个名称。Apatche已经变成世界上最流行的万维网服务器，这是因为其具有高性能和复杂的特性，并且因为事实上其源代码是免费开放的。
服务器108进一步包含包含由Apatche服务器122运行的CGI脚本的软件模块124。CGI是“Common Gateway Interface”(公共网关接口)的缩写，是在万维网服务器与应用程序之间来回传输信息的规范。CGI是HTTP协议的一部分。
在PC108上运行的Apatche服务器122解释通过因特网106从PDA102接收的命令。解释机构例如使用PC108上的一个数据库，其中所接收的每个具体命令都与一个特定行动相联系。数据库可完全由用户定制。本例中的命令被解释为开灯114这个行动。为此，PC例如通过RS232与控制器110通信，指示后者向开关112发出开灯114的命令。开关112接收该命令并将灯114与电源线116连接。类似地，当用户此后按下PDA102上的OFF(关)按钮时，客户应用程序120通过调制解调器104经因特网106向PC108发送相应的命令。Apatche服务器122解释该命令并指示控制器110让开关112关灯114。
系统110进一步包含服务器126(本文中称作可靠的内部服务(RHS))和摄像机128。RHS126可以是服务器108内的一个部件，或者是一个单独的低价服务器-就像本例中的那样。或者，万维网服务器122或脚本124可以是服务器126的部件。RHS126包含用于从视频源检索图象的硬件和软件-在本例中是从摄像机128检索静止图象。客户应用程序120提供软按钮“阅览”，当该按钮被按下时，让应用程序120通过调制解调器104和因特网106向服务器108发送命令。在PC108上运行的Apatche服务器122接收该命令，解释该命令，并指示RHS126检索一个静止图象并将其返回到Apatche服务器122。后者将该静止图象的格式转换成适合在PDA102的GUI118上显示的格式并将格式化的图象存储在PC108的数据库中。用户按下由客户应用程序120生成的另一个按钮“更新”。相关命令通过调制解调器104和因特网106被发送到PC108。Apatche服务器122接收该命令，解释该命令，并相应地从数据库中检索出所存储的图象，将其通过公共因特网协议返回到PDA102。PDA102然后在客户应用程序120的控制下在GUI118上显示该图象。
以上结合一些概念简单的例子解释了通过因特网的遥控。显然，用本发明可以实现其它更复杂的情形。例如，当用户意识到忘记或不能设置机器来转录喜爱的电视节目时，可以从世界的任何地方对诸如VCR或TiVO的记录设备编程。这方面，也参看美国序列号09/283,545(律师卷宗号PHA26，633)-该专利申请日1999年4月1日，申请人Eugene Shteyn，名称“时间和位置驱动的个人化电视”，在此引用作为参考。另一个例子是，用户可以在深夜驱车回家的路上打开中央暖气和点亮家中和花园中的电灯。另一个例子是，用户可以在工作或旅行时用程序设计或启动家中花园内的洒水装置。
