IBM's single chip encoders due in Q2, 98.....................ijumpstart.com Recognizing the significant growth potential in the MPEG-2 encoding market, IBM Microelectronics [IBM] has announced the expansion of its existing digital video product line to include next-generation, highly efficient single chip MPEG-2 encoders. The technological advancements behind IBM's new chip design promises to have positive impact on many manufacturers, including Lucent Technologies [LU], Tektronix, Leitch, Optibase, Tiernan, and Sonic Solutions [SNIC], all of whom currently incorporate IBM chips into their MPEG-2 products, such as encoders, decoders, and set-top boxes. "The new chips are basically super sets of the older three-chip sets from a functional standpoint. But, since three chips are being replaced by one chip, this new MPEG-2 product family will offer greater performance, require significantly less power, and generate less heat than the previous generation of chips," says Don Leake, manager for digital video products (including MPEG-2 4:2:2 decoder chips) for IBM Microelectronics, (http://www.chips.ibm.com), a division of IBM, in Yorktown, New York, "Manufacturers that use these new chips will find that those attributes will make their MPEG-2 encoders more attractive to prospective buyers." The three new single chip products, which support the international standard MPEG-2 4:2:2 Main Profile at Main Level (MP@ML), include: the MPEG-2 Professional Studio Encoder (MPEGS422), for high-quality video compression; the MPEG-2 Professional Broadcast Encoder (MPEGS420), which adds extensions for higher-quality 4:2:0 chroma video compression for high-end applications like DVD mastering; and the MPEG-2 I-Frame Video Encoder (MPEGSI), the industry's only product dedicated to I-frame encoding. The I-Frame (or intra-frame) encoder can be used for nonlinear editing since each I-Frame contains all the information needed to reconstruct a single frame. However, since there are no P-Frames and B-frames to perform the predictive processes, compression ratios tend to be lower. The fourth product in the new chip family is actually a multi-chip set consisting of either two or four of the MPEGS422 chips mounted on a different carrier that supplies a more highly-optimized connection enabling HDTV work. Leake noted, "Our design goal was to provide support for a wide range of DTV formats, including 1920 x 1080i." By ganging several chips together, IBM's chip designers accomplished this goal by extending the MPEG search range and motion estimation, as well as offer the maximum pixel addressability necessary to provide support for all the formats proliferating for HDTV.
