A camera system (100) comprises an image capturing device (102), object detection module (204), object tracking module (206), and match classifier (218). The object detection module (204) receives image data and detects objects appearing in one or more of the images. The object tracking module (206) temporally associates instances of a first object detected in a first group of the images. The first object has a first signature representing features of the first object. The match classifier (218) matches object instances by analyzing data derived from the first signature of the first object and a second signature of a second object detected in a second image. The second signature represents features of the second object derived from the second image. The match classifier (218) determine whether the second signature matches the first signature. A training process automatically configures the match classifier (218) using a set of possible object features.

Object matching for tracking, indexing, and search

A media distribution technique employs a multi-user server positioned at the terminal end of a broadcast media network The server receives broadcast media signals and selectively captures a portion of the signals for live personalized media streaming and/or storage for later personalized media streaming and/or download over a local distribution network to a collection of user receivers Request/control streams sent from the receivers to the server control real-time personalization of the media streams such as trick-play functions and channel selection Buffering and data storage segmentation techniques are used to provide highly responsive personal video recorder-like functionality to the multiple end users

Multi-user personalized digital multimedia distribution methods and systems

Live television broadcast and other information and entertainment programs, e.g., videos-on-demand (VOD), are provided to a user through a communications network, e.g., a cable network. A processing unit is employed at an headend of the communications network to respond to user requests for PVR-like functions, e.g., pausing, rewinding and fast-forwarding, to be performed on the program content being viewed. The processing unit in accordance with the invention causes a delivery of an appropriate version of the program content to meet such user requests.

Methods, systems, and products notify of alarms in security systems. Sensor data is received from an alarm sensor, and an alarm controller determines an alarm condition. Video data associated with the alarm sensor is retrieved. An alarm message may be sent over a wireless network connection, while the video data may be sent over a wireline broadband connection.

A method of generating a program signal stream comprises creating a sequence of serial programs that include a first event and a second, later occurring event and inserting a plurality of messages in the sequence of serial programs, between the first event and the second event The messages may be indicative of a time to the second event, as measured from each respective message of an elapsed time since the first event, to each respective message Alternatively or in addition, the messages may be at equal time intervals between the first event and second events The first and second events may be the start and end of a program or a program portion, such as a chapter, an advertisement, unscheduled content or an entire program, for example At least one message indicative of the time to the second event may be inserted in the sequence of serial programs prior to the first event

Use of multiple embedded messages in program signal streams

A coordinated surveillance system uses a larger number of fixed low resolution detection smart camera devices and a smaller number of pan/tilt/zoom controllable high resolution tracking smart camera devices. The set of detection cameras provide overall continuous coverage of the surveillance region, while the tracking cameras provide localized high resolution on demand. Each monitor camera device performs initial detection and determines approximate GPS location of a moving target in its field of view. A control system coordinates detection and tracking camera operation. A selected tracking camera is controlled to focus in on, confirm detection, and track a target. Based on a verified detection, a guard station is alerted and compressed camera video is forwarded to the guard station from the camera(s). The guard station can direct a patrol guard to the target using GPS coordinates and a site map.

A smart camera device incorporates a first processing path for video display processing and a second processing path for detection and/or tracking processing. A sensor device provides input signals including first size data units to both processing paths, at least some of the same input signals are processed by both processing paths. The video display processing generates second size data units which are smaller than first size data units. First size data units provide more information to the detection/processing module than second size data units would have provided if used. IR detection capability is improved by using first size data units. Detection and/or target tracking operations generate control signals used to control the video display processing to enhance the visual perceptibility of a detected target. Detection and/or target tracking operations generate target information signals conveying an indication of target detection, target identification information, target location information, and/or camera control signal.
