    • Portable audience measurement architectures and methods for portable audience measurement are disclosed. A disclosed system contains a plurality of portable measurement devices configured to collect audience measurement data from media devices, a plurality of data collection servers configured to collect audience measurement data from the plurality of portable measurement devices, and a central data processing server. A portable measurement device establishes a communication link with a data collection server in a peer-to-peer manner and transfers the collected audience measurement data to the data collection server. Because the portable measurement device is not dedicated to a particular local data collection server, the portable measurement device periodically or a periodically broadcasts a message attempting to find a data collection server with which to establish a communication link.
    • 公开了便携式观众测量的便携式观众测量结构和方法。 所公开的系统包括多个便携式测量设备,其被配置为从媒体设备收集观众测量数据,多个数据收集服务器被配置为从多个便携式测量设备收集观众测量数据,以及中央数据处理服务器。 便携式测量设备以对等方式与数据收集服务器建立通信链路,并将收集的受众测量数据传送到数据收集服务器。 由于便携式测量设备不专用于特定的本地数据收集服务器,便携式测量设备周期性地或周期性地广播尝试找到用于建立通信链路的数据收集服务器的消息。

    • A method that allows the optimization of the consumption of conditional access content in order to guarantee less vulnerable right messages involves three steps: the selection by the user of a content and the indication of this interest to said management center; the sending of a notification message containing or indicating the access authorisation message shortly before the broadcast of said content and storage of this authorisation message; and the sending of the content itself and the use of the data of the authorisation message in order to access the data of the content. There may be a fourth stage, namely the validation of the authorisation message by the user. This validation is executed in general at the time of the reception of the content or alternatively the user confirms their intention to purchase.
    • 允许优化条件访问内容的消费以便保证较不脆弱的正确消息的方法涉及三个步骤:用户选择内容和对所述管理中心的兴趣的指示; 在广播所述内容之前不久发送包含或指示访问授权消息的通知消息并存储该授权消息; 以及发送内容本身以及使用授权消息的数据以便访问内容的数据。 可能有第四阶段,即用户验证授权消息。 该验证通常在接收内容时执行,或者用户确认他们的购买意图。
