A method of inserting auxiliary data of a television signal into an auxiliary video output signal derived from said television signal comprising: receiving in a television signal processing system a television signal having a video component and an auxiliary data component, the video component including a plurality of frames, each frame comprising a first field and a second field, each field having a plurality of television lines of information; processing the television signal to provide the processed video component of the television signal as a main video signal and to provide said processed video component of the television signal as an auxiliary video signal as well; processing the television signal to extract auxiliary data from the auxiliary data component; synchronizing the extracted auxiliary data with the main video signal utilizing an interrupt signal of the main video signal, characterized by synchronizing the extracted auxiliary data with the auxiliary video signal utilizing an interrupt signal of the main video signal by determining if field inversion exists between the frames of the auxiliary video signal and the frames of the main video signal and by inverting fields of the frames of the auxiliary video signal if it is determined that field inversion exists between the main video signal and the auxiliary video signal; and outputting the synchronized extracted auxiliary data along with the resulting auxiliary video signal to an auxiliary output of the television signal processing system while outputting the synchronized extracted auxiliary data along with the main video signal to a display connection of the television signal processing system. receiving in a television signal processing system a television signal having a video component and an auxiliary data component, the video component including a plurality of frames, each frame comprising a first field and a second field, each field having a plurality of television lines of information; processing the television signal to provide the processed video component of the television signal as a main video signal and to provide said processed video component of the television signal as an auxiliary video signal as well; processing the television signal to extract auxiliary data from the auxiliary data component; synchronizing the extracted auxiliary data with the main video signal utilizing an interrupt signal of the main video signal, characterized by synchronizing the extracted auxiliary data with the auxiliary video signal utilizing an interrupt signal of the main video signal by determining if field inversion exists between the frames of the auxiliary video signal and the frames of the main video signal and by inverting fields of the frames of the auxiliary video signal if it is determined that field inversion exists between the main video signal and the auxiliary video signal; and outputting the synchronized extracted auxiliary data along with the resulting auxiliary video signal to an auxiliary output of the television signal processing system while outputting the synchronized extracted auxiliary data along with the main video signal to a display connection of the television signal processing system.
