摘要:
A method for monitoring motion of an entity within a predetermined boundary established using a location detection technology. Sensor data is acquired from a motion sensor that senses non-positional movement of the entity and is attachable to the entity. A learned movement pattern associated with the entity is accessed. Computing techniques are used to analyze the acquired sensor data in relationship to the learned movement pattern. A current movement pattern is identified based on the analysis. It is determined whether the current movement pattern is a reportable movement pattern, and if so, a predetermined action is performed.

A method for clearing teletext data includes transmitting the teletext to a display device, tracking the transmitted teletext data, generating a representation of the transmitted teletext data, accessing the representation upon a channel change, and instructing the display device to clear the transmitted teletext data according to the accessed representation of the transmitted teletext data.

A method (40, 50) and apparatus (30) for processing a video signal inserts a unique digital signature into the video signal. Thus, rampant duplication or distribution can be traced back to a particular set-top box or receiver. According to one aspect of the present invention, the unique digital signal is inserted into the vertical blanking interval. An apparatus (30) for processing a video signal includes a processor (31) receiving the video signal and outputting a modified video signal having a vertical blanking interval, which includes a digital signature uniquely identifying the processor (31). A memory (33) stores the digital signature and a teletext generator (32) coupled to the memory (33) and the processor (31) and generates a teletext signal that includes the digital signature for insertion into the vertical blanking interval by the processor (31) prior to the processor (31) outputting the video signal.
