An automated batch identifier registration and embedding system for media signals, such as image, video and audio files. A batch identifier registration system enables a user to submit a request for a batch of unique identifiers to be embedded in media signals. The user submits a request for a batch of IDs. The batch registration system verifies the accuracy of the request, sends a confirmation, allocates IDs, creates corresponding entries in a registration database, and creates embedder files used in a batch embedding process. The user may then submit a request for embedder files. To perform automated batch embedding, a watermark embedder takes the embedder files and corresponding list of media signal files as input and automatically embeds identifiers supplied in the embedder files into corresponding media signal files.

A system for determining location and timing information in a cellular network includes a space-time calibration unit (SCU) and a plurality of nodes in communication with the SCU. Each node includes a node ping driver that receives frame synchronization information from a respective subset of cell sites, and associates the frame synchronization information with respective receive count stamps generated using a local node clock. The system also includes a user handset that includes a handset ping driver that receives the frame synchronization information from a serving cell site and one or more neighbor cell sites, and associates the frame synchronization information with respective receive count stamps generated using a local handset clock. The SCU uses the information from the node and handset ping drivers to determine a handset location.

The present invention relates generally to processing video signals. One claim recites a method including: utilizing a multi-purpose electronic processor programmed for analyzing a video signal to derive or calculate an identifier from data representing picture elements of the video signal or from data representing audio accompanying the video signal; providing the identifier to electronic memory or to a remote repository to obtain advertizing information; receiving advertizing information from the electronic memory or the remote repository; and controlling rendering of the advertizing information such that the advertizing information is synchronized with at least a portion of the video signal when rendered. Of course, other combinations and claims are provided as well.

Phasor Measurement Units (PMUs) tend to be specialized and expensive—relegated to only key points in power distribution networks, and are generally reliant on GPS technology. The present disclosure details how any smart meter—using wireless communication—can perform sub-microsecond-grade synchrophasor measurements. Other aspects concern smart meter-based determination of A, B or C phase of the tri-phase power network. This can involve count-stamp enabling message packets sent to and/or from a smart meter, and then associating such count-stamps to local measurements of power phase by a metrology unit. Once a network of such enabled smart meters and other devices is formed, sub-microsecond metropolitan-wide and entire region-wide synchronizing time standard can calibrate local measurements of power phase, where simple A, B and C phase determination is one low hanging fruit application of such. Low cost aggregate monitoring of metropolitan-wide synchrophasors promises a next chapter of importance for that relatively recent art.

A method of segmenting a media signal for parallel watermarking operations sub-divides the media signal into segments, distributes the segments to parallel processors, and performs parallel digital watermark operations on the segments in the parallel processors. These parallel processors may comprise separate threads of execution on a processing unit, or several execution threads distributed to several processing units. In one enhancement, the method prioritizes the segments for watermarking operations. This enables finite processing resources to be allocated to segments in order of their priority. Further, processing resources are devoted to segments where the digital watermark is more likely to be imperceptible and/or readable. A system for distributed watermark embedding operations includes a watermark signal generator, a perceptual analyzer and a watermark applicator. The system supports operation-level parallelism in the concurrent operation of watermark embedder modules, and data parallelism in the concurrent operation of these modules on segments of a media signal to be embedded with an imperceptible digital watermark.

The present disclosure describes, e.g., electronic tickets, coupons and credits. In some cases these electronic objects are represented by imagery or audio. One claim recites a handheld apparatus including: an input for receiving an electronic coupon or credit, the electronic coupon or credit comprising audio; electronic memory for storing a received electronic coupon or credit; an audio output for outputting the received electronic coupon or credit, in which the electronic coupon or credit is intended to be applied to a purchase or transaction; and an electronic processor programmed for controlling output of the received electronic coupon or credit. Of course, other claims and combinations are provided too.
