METADATA ACQUISITION USING EMBEDDED WATERMARKS

摘要

Methods, devices and computer program products are described that improve acquisition of metadata that is associates with a multimedia content, such an audio or video content. In one exemplary method, the multimedia content is received at a first device that is equipped with a watermark detector and watermark extraction operations are conducted to detect a plurality of watermark messages. Each watermark message includes a server code and an interval code. In this method, a server Internet Protocol (IP) address is obtained that corresponds to a server that stores at least a portion of the metadata associated with the multimedia content. The IP address corresponds to at least one of the server codes detected from the plurality of watermark messages. According to the above method, the metadata is requested from the server having the server IP address, and a response including the metadata associated with the multimedia content is received.

主权项

1. A method for acquiring metadata for a multimedia content, comprising:
receiving the multimedia content at a first device equipped with a watermark detector that is implemented at least partially using electronic circuitry; conducting watermark extraction operations using the watermark detector to detect a plurality of watermark messages from the multimedia content, each watermark message including a server code and an interval code; obtaining a server Internet Protocol (IP) address corresponding to a server that stores at least a portion of the metadata associated with the multimedia content, the IP address corresponding to at least one of the server codes detected from the plurality of watermark messages; requesting the metadata from the server having the server IP address; and receiving a response including the metadata associated with the multimedia content.
