    • Methods and devices are provided to obtain associated information for a multimedia content. One such method includes receiving a content at a receiver device equipped with a watermark detector, performing watermark detection on the received content to extract a payload of an embedded watermark. The payload comprises a first field that includes a server identifier and a second field that includes an interval identifier associated with the server identifier. The first field provides a mapping to an Internet address accessible to retrieve metadata associated with content segments identified by the watermark payload. In this method, based on the detected watermark payload, a query is formed and transmitted to a server identified by the Internet address, and a response to the query is received from the server that includes metadata associated with the content.
    • 提供方法和设备以获得关于多媒体内容的相关信息。 一种这样的方法包括在配备有水印检测器的接收机设备处接收内容,对接收到的内容执行水印检测以提取嵌入水印的有效载荷。 有效载荷包括包括服务器标识符的第一字段和包括与服务器标识符相关联的间隔标识符的第二字段。 第一个字段提供可访问的互联网地址的映射,以检索与由水印有效负载标识的内容段相关联的元数据。 在该方法中,基于检测到的水印有效载荷,形成查询并将其发送到由因特网地址标识的服务器,并从服务器接收到包含与该内容相关联的元数据的对查询的响应。
