[The Chosun Ilbo, December 21 2007] Korean Researchers Develop Better Video Compressor

The Electronics and Telecommunications Research Institute said Thursday that it has developed an ultra low-power H.264 encoder, which can compress full high-density video. The new technology offers 50 percent greater compression and uses 40 percent less power than the existing MPEG4 encoder.

That means camcorders and digital cameras that use the new encoder could use about 70 percent less battery power than existing devices. H.264 compresses video images to one-two hundredth of their original size for storage on a hard disk, while MPEG4 reduces them to one-one hundredth of their original size.

Dr. Park Sung-mo, who developed the technology, said that the success of technologies for mobile video devices lies in reducing power consumption. "The new technology is a prototype, and will be used for digital devices from next year," he said.
