Abstract
The present invention provides for inductive pick-up devices employing a diversity and adaptive antenna arrangement. By utilizing diversity and adaptive antennas, the pick-up can be installed by a consumer without use of a computer monitor or other device to determine alignment. In addition, the arrangement increases the level of signal available to a data decoding system. In combining the two types of pick-ups and using the best features of both, we additionally gain performance on synchronizing frame rate and picking up data.
Claims3
A pick-up system for capturing and processing an information signal radiated from a display device located proximate to the pick-up device, the display device having a set top box associated therewith, the pick-up device comprising:
- an antenna array arrangement including:
- at least two antennas for respectively receiving emissions radiated from the display device;
- at least two signal monitors, respectively coupled to the at least two antennas, for respectively detecting the information signal from the received emissions;
- at least one of a diversity algorithm-based processing portion and an adaptive algorithm-based processing portion for analyzing the information signals detected by the at least two signal monitors and yielding an information signal for decoding by a decoder;
- and
- a decoder for decoding an information signal received from at least one of the diversity algorithm-based processing portion and the adaptive algorithm-based processing portion;
- a signal comparator, coupled to the antenna array arrangement and the set top box, for comparing a signal decoded by the antenna array arrangement and a signal decoded by the set top box;
- and
- an application processor, selectively coupled to the antenna array arrangement and the set top box, for receiving the decoded signal from the antenna array arrangement when the signal decoded by the antenna array arrangement and the signal decoded by the set top box are determined by the signal comparator to not be substantially similar, and receiving the decoded signal from the set top box when the signal decoded by the antenna array arrangement and the signal decoded by the set top box are determined by the signal comparator to be the substantially similar.
