MULTIMEDIA PRESENTATION TRACKING IN NETWORKED ENVIRONMENT

摘要

Methods, devices, systems and computer programs facilitate presentation of a second content in synchronization with a first content. In one method, at least a portion of a first content that is being presented by a first device is received at a second device. The first content includes substantially imperceptible watermarks that are embedded in one or more components of the first content. A first watermark detection result is obtained by performing a watermark detection operation. Additionally, a second watermark detection result associated with the first content is received at the second device from a device other than the second device. The first watermark detection result and the second watermark detection result are augmented to obtain a combined watermark detection result, and the combined detection result is used to enable presentation of a second content in synchronization with the first content.

主权项

1. A method, comprising:
receiving, at a second device, at least a portion of a first content being presented by a first device, the first content comprising substantially imperceptible watermarks that are embedded in one or more components of the first content; performing watermark detection operations to obtain a first watermark detection result; receiving, at the second device, a second watermark detection result associated with the first content from a device other than the second device; augmenting the first watermark detection result and the second watermark detection result to obtain a combined watermark detection result; and using the combined detection result to enable presentation of a second content in synchronization with the first content.
