Abstract: A vehicle collision warning prevention method includes the steps of: (a) extracting a forward video of a vehicle and video recognition information from a video recognition module mounted in a vehicle, and detecting a size change rate of a forward object included in the video recognition information at each frame of the forward video; (b) calculating an average OFCR of a predetermined frame section; (c) determining whether a value obtained by subtracting the average OFCR from a current OFCR is less than a predetermined threshold value; (d) determining that a brake operation signal is generated when it is determined that the value is less than the threshold value; (e) determining whether a collision warning signal is generated within a predetermined time after the step (d); and (f) preventing an output of the collision warning signal when the collision warning signal is generated at the step (e).

Abstract: Disclosed is a broadcasting signal receiving apparatus comprising: a signal receiver configured to receive a broadcasting signal of a channel tuned among a plurality of channels; an information processor configured to process channel information embedded in the broadcasting signal; a plurality of signal processors configured to sequentially perform a plurality of signal processes based on the channel information with respect to the received broadcasting signal; a storage configured to store the channel information processed by the information processor; and a channel-switching setting portion comprising channel-switching setting circuitry configured to perform a channel-switching setting operation for at least one among the plurality of signal processors based on the channel information stored in the storage in response to switching of the channel. Thus, when a channel of a broadcasting signal is switched, it is possible to quickly switch the channel using the stored channel information.
