The IVDS system consists of a Consumer Control Unit which transmits user requests, a Repeater Unit which receives transmissions from the CCUs, and a Host System which takes appropriate actions for user demands. This thesis follows the evolution of the original CCU prototype as more capabilities are added and hardware platforms are changed, focusing on the addition of a bar code interface to the CCU.In CopyrightIVDSinteractive videobar codesuniversal remotesspread spectrumThesishttp://scholar.lib.vt.edu/theses/available/etd-316151699632891/
