Abstract:
A video encoding apparatus receives a digital video data signal, converts the digital video data signal into an analog video signal and outputs the analog video signal to an externally connected image device. An encoding processor converts the digital video data signal into the analog video signal. A resolution determination unit compares the resolution of an image represented by the digital video data signal with an externally defined resolution. An output controller refers to a result of comparison by the resolution determination unit and, if the externally defined resolution matches the resolution of the image represented by the digital video data signal, outputs the analog video signal. If the resolutions do not match, the output controller restricts the output of the analog video signal.
