Oki Develops MPEG-4 Encoder LSI.Achieves High-Quality Video With Its Proprietary Algorithm TOKYO -- Oki Electric Industry Co., Ltd. (TOKYO:6703) today announced it has developed a single chip LSI LSI: see integrated circuit. (Large Scale Integration) Between 3,000 and 100,000 transistors on a chip. See SSI, MSI, VLSI and ULSI. , ML86410 that enables real-time encoding See encode. 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 Encoding digital video to take up less storage space and transmission bandwidth. See video codec and data compression. video compression - Compression of sequences of images. . Oki will provide samples of this chip starting today. "Our technologies for high-speed and high-quality video have been refined through our video delivery server, 'OKI MediaServer.' Based on these technologies, we have succeeded in enabling MPEG-4 encoding utilizing a dedicated hardware accelerator, which previously had to be done using software," said Masahiko Morioka, President of Silicon Solutions Company at Oki Electric. "Because of the quality and cost reduction it can offer, we believe this LSI will be an excellent solution for use in video equipment such as monitoring cameras and network cameras." 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 ML8641 does not require a high-speed CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. and DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive 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 A hardware device or software that converts coded data back into its original form. See decode and MPEG 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. Going forward, Oki plans to develop audio encoders, LSIs with video/audio multiplexing multiplexing, in communication, technique whereby two or more independent messages, or information-bearing signals, are carried by a single common medium, or channel. function, MPEG-4 codec (1) (enCOder/DECoder) A hardware circuit that performs analog-to-digital conversion (ADC) and digital-to-analog (DAC) conversion. When analog signals are entered into a computer, cellphone or other device via a microphone or video source such as VHS tape or analog TV, LSIs, H.264-related LSIs, all based on this chip, thus providing various applications to its customers. This LSI will be exhibited at the OKI Info-Telecom Solutions Fair 2006 to be held at Roppongi Hills Roppongi Hills (六本木ヒルズ Roppongi Hiruzu , Tokyo from November 9th to 10th.
