METHOD AND SYSTEM FOR TRANSMITTING AND DECODING DATA IN A SIGNAL

摘要

A data processing system (FIG. 9) comprises a software-oriented implementation for extracting partial response coded data (FIG. 21) from a vertical blanking interval of a television signal. The system synchronizes to a synchronization signal, such as a color burst, and extracts the multi-level coded data (FIG. 4A-4B). The system may include multiple modes having different bit transfer rates (FIG. 22) to accommodate various transmission environments and transmission rates.
