Title:
METHOD AND SYSTEM FOR DECODING DATA IN THE HORIZONTAL OVERSCAN PORTION OF A VIDEO SIGNAL
Document Type and Number:
WIPO Patent Application WO2001050748
Kind Code:
A3
Abstract:
A method and system for decoding control data from the horizontal overscan area of a video signal and for ensuring that control data is received in the order in which the signal was transmitted. Because the control data is concatenated with the video signal on a line basis, the control data is temporarily synchronized with the underlying video signal. This permits the controlled devices, such as wireless mechanical characters, behave as characters in a scene defined by the programming information of the video signal. A protocol is defined for the encoded data that is addressable, forwardly compatible, error tolerant, and feasible to deploy in connection with a system that is primarily intended to be a children's entertainment product. The bandwidth of the communication link defined by the encoded data is adjustable to meet the cost and performance needs of a wide variety of consumers.
