    摘要： A system for transmitting an audio signal in pulse width modulated form on a video signal is disclosed. The audio signal is modulated by varying the time occurance of at least one edge of a pulse as a function of the voltage level of said audio signal at a selected time. The pulse is then added to the video signal during each horizontal blanking interval. Upon receipt of the transmitted signal, the video signal is processed to reform said edge varying pulse. An output pulse is then generated for each varying edge of said pulse, whose pulse width is a function of the time of occurance of said edge with respect to a stable reference edge. This output pulse is then used to generate a voltage signal whose level is determined by the pulse width of said output pulse. The successively generated voltage levels comprise the reformed audio signal.

    摘要： Provided are a method and apparatus for transceiving an asymmetric point-to-point moving signal and securing an uplink channel using a horizontal blanking interval (HBI) in which a video signal transceiving apparatus can combine a plurality of HBIs and a plurality of active lines (ALs) into a single section, and when auxiliary data exists in a corresponding HBI, can change an order of the HBI to the last and transmit map information including arrangement information to a video signal display apparatus, and the video signal display apparatus can receive the map information and analyze the received map information to thereby acquire an uplink channel using HBI excluding auxiliary data and transmit control signal data via the acquired uplink channel.
