SmartCODEC image compression for automotive apps

October 9, 2006 There is an increasing need to use multiple video channels in automobiles, such as for video images from multiple surveillance (rear vision, backing and parking cameras), navigation system images and video for passengers watching on rear-seat monitors. Analog signals have been used thus far but require a separate cable to be wired for each channel, a process that has become complicated as the number of channels has increased. This has resulted in demand for a technology capable of multiplex transmission of images on a single in-vehicle LAN. Fujitsu has developed image compression specifically for automotive use with a compression rate of one-third (1/3), and a compression-decompression time of just 2 to 3 milliseconds that enables compression and multiplex transmission of images to inside the vehicle, such as images from multiple automotive cameras located externally on the vehicle. This not only makes for a safer car, but a cheaper car as it will reduce the amount of cable required within a vehicle.
