Abstract

PURPOSE: A method of encoding a digital video signal in a security camera, a camera including a circuit using the encoding method, and a security system with the camera are provided to prevent a video signal transmitted from the security camera from being hacked by an external intruder. CONSTITUTION: A vertical and horizontal synchronous signals(121,122) and effective video data are separated from an input digital video signal. The vertical and horizontal synchronous signals are supplied to a key data supply(132) and the effective video date is provided to a video data encoder(133). When the vertical synchronous signal is supplied to the key data supply, a specific encoding key data is selected from a plurality of encoding key data items to be provided to the video data encoder in order to initialize the video data encoder. When the horizontal synchronous signal is provided to the key data supply, the plurality of encoding key data items are sequentially supplied to the video data encoder. The video data encoder encodes the effective video data with the input encoding key data.
