另一种可选的实现方案是, 由第一终端 100或第二终端 200在交互内容 获取请求中携带所述内容视图信息。 相应地, 第一终端 100或第二终端 200 还包括视图信息获取单元, 当第一终端 100输出所述播放内容且发送交互内 容请求时, 用于获取所述播放内容的内容视图信息; 所述关联终端输出所述 播放内容且当前终端发送交互内容请求时, 比如第一终端 100输出播放内容 且第二终端 200发送交互内容请求, 则第二终端的视图信息获取单元接收所 述关联终端即第一终端 100获取并发送的所述播放内容的内容视图信息; 当 前终端输出所述播放内容且关联终端发送交互内容请求时, 比如第一终端 100输出播放内容且第二终端 200发送交互内容请求, 则第一终端 100的视 图信息获取单元获取并发送播放内容的内容视图信息至关联终端即第二终端 200。
上文所说的内容视图信息至少包括:
内容元数据: 频道标识、 节目标识、 时间戳;
播放进度: 播放状态、 剩余时间;
内容视图特征: 数字指紋、 数字水印。
具体地, 所述内容视图特征至少可以通过下列方式获取:
第一终端 100提取其播放内容緩存中的多媒体緩存信息, 通过媒体特征 分析获取所述内容视图特征。 或者,
第二终端 200拍摄第一终端 100播放内容截屏画面, 通过媒体特征分析 获取所述内容视图特征。
根据上文描述, 交互内容获取包括但不限于以下三种方式: 方式一、 直接请求获取交互内容
第一终端 100或第二终端 200请求应用服务器 300获取交互内容。
方式二、 请求推送交互内容
第一终端 100请求应用服务器 300获取并推送交互内容至第二终端 200。 方式三、 通知第二终端获取交互内容
第一终端 100通知第二终端 200根据所述内容视图信息请求应用服务器 300获取交互内容。
具体地,还可基于实现可能性叠加其中的某两种方式,比如第一终端 100 请求获取交互内容并推送至第二终端 200。
