ML86410 enables real-time encoding of MPEG-4 data. By using Oki's proprietary algorithm and developing an accelerator designed for this chip, Oki succeeded in developing low cost, high-quality video compression.

Compared to Motion-JPEG, the encoding method conventionally used for video encoding, MPEG-4, the international standard for video encoding, offers a higher compression rate. By using the MPEG-4 standard, Oki succeeded in developing an MPEG-4 encoder LSI with a high compression rate and high video quality.

In addition, with the accelerator designed for the chip, the ML86410 does not require a high-speed CPU and DSP as required for conventional MPEG-4 encoding schemes.

This solution offers lower power consumption and significant cost reduction. The LSI also maintains its high video quality when replaying fast action scenes or when in the low bit rate mode, due to its high-speed, high-quality movement detection method and precise controlling of the encoded data.

Oki will also offer its high-performance viewer software (MPEG-4 decoder) and "MPEG-4 Network Camera Reference Design," which consists of various Oki video and image LSIs and software to enable customers to easily build an MPEG-4 network camera system.
