    • Various technologies and techniques are disclosed that relate to providing interactive television by synchronizing content to live and/or recorded television shows. Content is synchronized without the use of in-band triggers. A broadcast stream is received, and search/action pairs are received from a transmission path, such as from the Internet or user. When the search criteria are found in the broadcast stream, the associated action is performed and the content is synchronized with the show. An application programming interface is used to facilitate synchronization, and includes a set search method, a search function template method, and a clear search method. The set search method initiates searching of the broadcast stream and registers one or more callback methods for performing the associated action when the match is found. The search function template serves as the template for registering the callback methods. The clear search method clears the system resources from the search.
    • 公开了涉及通过将内容与现场和/或记录的电视节目同步来提供交互式电视的各种技术和技术。 内容同步而不使用带内触发。 接收广播流,并且从诸如来自因特网或用户的传输路径接收搜索/动作对。 当在广播流中找到搜索条件时,执行相关联的动作并且内容与节目同步。 应用编程接口用于促进同步,并且包括集搜索方法,搜索功能模板方法和清晰搜索方法。 设置搜索方法发起广播流的搜索,并且在发现匹配时注册用于执行相关联的动作的一个或多个回调方法。 搜索功能模板作为注册回调方法的模板。 清除搜索方法从搜索中清除系统资源。

    • Described is a technology by which a virtual location marker (e.g., virtual pushpin or similar placeholder) is determined from the results of a query, in which the virtual location marker corresponds to a first coordinate set (e.g., a latitude, longitude and/or altitude of a business location) to represent a point on a map. Various static and dynamic data may be used to select a result deemed most desirable from among multiple query results. The virtual location marker may be output, e.g., plotted on a map and/or used to provide audio directions. Upon detecting a state change, such as a change in current location, and/or a change in direction, speed, time, a start location or an end destination, the virtual location marker may be automatically re-determined, including changing the virtual location marker to correspond to a second, different coordinate set now deemed most desirable in view of the state change.
    • 描述了一种技术,通过该技术,从查询的结果确定虚拟位置标记(例如,虚拟图钉或类似占位符),其中虚拟位置标记对应于第一坐标集(例如,纬度,经度和/或 商业位置的高度)来表示地图上的一个点。 可以使用各种静态和动态数据来从多个查询结果中选择被认为最理想的结果。 虚拟位置标记可以被输出,例如绘制在地图上和/或用于提供音频方向。 在检测到诸如当前位置的变化和/或方向,速度,时间,开始位置或结束目的地的变化的状态改变时,可以自动地重新确定虚拟位置标记,包括改变虚拟位置 标记对应于现在认为是鉴于状态变化最期望的第二不同坐标集。
