NEC has developed an Mpeg-4 coder/decoder which will enables users to send and receive high quality video and audio on next generation mobile phones and the Internet.
The company is billing the Codec as a breakthrough development which will make mobile video phones and video email a realistic possibility for the first time.
ISDN teleconferencing and video phones both use Codec technology but high cost and power consumption have prevented the technology from being translated to the portable arena to date.
The NEC Codec will enable screen reproduction of 10-15 frames a second at half the power consumption of other contemporary devices, in a single chip digital signal processor (DSP).
The DSP and its two audio and video Codecs can be embedded in a microprocessor and mounted on a credit card-sized board for analog/digital interfaces.
The technology is expected to come into its own early next century, with the spread of next-generation mobile communications services.
NEC plans to further miniaturise its device before releasing a marketable product, which it hopes will become industry standard.
The Codec conforms to the Mpeg-4/Visual and H.263 version 2 video data compression standards and the G.723.1 audio standard.
