    • Particular embodiments provide a hybrid approach to confirming a presence of the second-screen device in a same location as a first-screen device. In one embodiment, a trigger phase and a confirmation phase are used to confirm the presence of the second-screen device in a physical proximity to the first-screen device. The trigger phase may be performed at a back-end system. The back-end system may detect events for the content being delivered to the first-screen device using content detection techniques. The back-end system may generate a trigger event when certain conditions are met based on the detection. Once the trigger event is detected, the back-end system may confirm that the second-screen device is physically present in a same location with the first-screen device. For example, the back-end system may communicate with the second-screen device to initiate a content detection analysis on the second-screen device.
    • 具体实施例提供了一种用于确认第二屏幕设备在与第一屏幕设备相同位置的存在的混合方法。 在一个实施例中,使用触发相位和确认阶段来确认第二屏幕设备在物理上接近第一屏幕设备的存在。 触发相位可以在后端系统中执行。 后端系统可以使用内容检测技术检测正在传送到第一屏幕设备的内容的事件。 当基于检测满足某些条件时,后端系统可能会产生触发事件。 一旦检测到触发事件,后端系统可以确认第二屏幕设备物理地存在于与第一屏幕设备相同的位置。 例如,后端系统可以与第二屏幕设备通信,以在第二屏幕设备上发起内容检测分析。
