PROBLEM TO BE SOLVED: To provide a distributed reader architecture for a mobile computing device such as a cellular telephone handset.SOLUTION: A reader library reads a device function and a business model parameter present in the device, and in response, selects an appropriate configuration of reader modules for identifying a content item. The reader modules each perform a function used in identifying a content item. The reader modules are selected such that the resources available on the device and in remote devices are used optimally, depending on available computing resources on the device and network bandwidth. One example of the reader module is a fast watermark detection module. A watermark signal structure for fast watermark detection comprises a dense array of impulse functions in a form of a circle in a Fourier magnitude domain. |
