    • A source device determines content rights for encrypted content in the first encoding standard using a first rights data file. The source device creates a second rights data file for transcoded content in the second encoding standard. The source device performs a key management operation including communicating a decryption key for the encrypted content in the first encoding standard to a transcoder. The source device transfers the encrypted content in the first encoding standard to the transcoder. The transcoder decrypts the encrypted content, transcodes the content from the first encoding standard to the content in the second encoding standard, and re-encrypts the content in the second encoding standard using a second encryption key. The transcoder then transfers the encrypted content in the second encoding standard to an indicated device.
    • 源设备使用第一版权数据文件来确定第一编码标准中的加密内容的内容权限。 源设备为第二编码标准中的经转码的内容创建第二版权数据文件。 源设备执行密钥管理操作,包括将第一编码标准中的加密内容的解密密钥传送到代码转换器。 源设备将第一编码标准中的加密内容传送到代码转换器。 代码转换器解密加密的内容,将内容从第一编码标准转码为第二编码标准中的内容,并且使用第二加密密钥对第二编码标准中的内容重新加密。 然后,代码转换器将第二编码标准中的加密内容传送到指定的设备。

    • Disclosed is a method for aggregating parallel data links connecting two end-point devices into a logical link. If one of the parallel data links is a multi-point link, then an end-point device can still access that link to route traffic to an end station on the link (that is, to a device other than the other end-point device of the logical data link). In the terminology of this disclosure, the logical aggregated link is accessed through an “aggregated port” on an end-point device, while the constituent multi-point link is accessed directly through a “singleton port.” By assigning a smaller cost to the aggregated port than to the singleton port, embodiments avoid creating routing loops. In some embodiments, the aggregation is performed at Layer 2 of the Open System Interconnection seven-layer protocol model. Then, the methods of the present invention work well with existing IEEE 802.1 bridging architectures and protocols.
    • 公开了一种用于聚合将两个端点设备连接成逻辑链路的并行数据链路的方法。 如果并行数据链路之一是多点链路,则端点设备仍然可以访问该链路以将流量路由到链路上的终端站(即,到另一端点设备之外的设备 的逻辑数据链接)。 在本公开的术语中,逻辑聚合链路通过端点设备上的“聚合端口”来访问,而组成的多点链路通过“单一端口”直接访问。通过将更小的成本分配给 聚合端口比单端口,实现避免创建路由环路。 在一些实施例中,聚合在开放系统互连七层协议模型的层2处执行。 然后,本发明的方法与现有的IEEE 802.1桥接架构和协议一起工作良好。

    • Systems and methods for remote query of weather conditions at an agricultural machine use an onboard telemetry unit as a gateway for communication with the machine. The telemetry unit can be coupled to both the machine's electrical system at the machine, and a machine's controller area network (CAN). A user can call up the machine's telemetry unit using a cell phone or personal computer to retrieve weather data such as temperature, humidity and rainfall from a weather station coupled to the machine. A system can provide an alert when a desired predetermined condition is present at a machine, for example an alert that a harvesting or baling condition is present. The system can also enable an operator or fleet manager to check the state of various devices or apparatus at a machine, enabling remote diagnostics via the onboard telemetry unit.
    • 用于远程查询农业机器天气状况的系统和方法使用机载遥测单元作为与机器进行通信的网关。 遥测单元可以连接到机器的机器电气系统和机器的控制器区域网络(CAN)。 用户可以使用手机或个人计算机来调用机器的遥测单元,以从耦合到机器的气象站检索诸如温度,湿度和降雨量的天气数据。 当机器上存在期望的预定条件时,系统可以提供警报,例如存在收割或打包条件的警报。 该系统还可以使操作员或车队管理者能够检查机器上各种设备或设备的状态,从而通过机载遥测单元实现远程诊断。
