  • Patent number: 8961183
    Abstract: Embodiments of the present invention are generally directed to an Audio-Story Engine that includes a repository of prerecorded audio files that, when played in a certain sequence, with user provided recordings placed throughout, tell a story. To obtain the user provided recordings, the Audio-Story Engine asks the user to make audio recordings of various words or phrases. For example, the Audio-Story Engine may ask the user a series of questions in order to record and store the user's audible responses. Upon completion, the Audio-Story Engine plays back a completed story that incorporates the user's audio recordings by playing an appropriate user recording after playing a prerecorded audio file. This is repeated several times in sequence to form a seamless, customized, audio story. In addition, the Audio-Story Engine may alter the pitch or sound of the user's recorded words to match the pitch of the prerecorded story.

  • Patent number: 6742188
    Abstract: A method and system for encoding control data into the horizontal overscan area of a video signal. Because the control data is concatenated with the video signal on a line-by-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.
