Unfortunately the lines of communication only open occasionally. A couple of points about GI: 1) Since GI owns 2 1/4 million shares of Broadcom, I would assume Broadcom would be the silicon of choice. It is possible that Broadcom's chips might not meet requirements, I'm not familiar with their technology. 2) There is an interesting quote in GI's annual report in big bold letters - "Joint ventures are being formed to supply the Chinese government in its plan to build a 'villages network.' This network is designed to bring educational and entertainment programming from China's two largest television broadcasters to as many as 800,000 villages, which represents most of China's one billion-plus population." It sounds like China is building the infrastructure to turn it into the largest video market in the world. This could be huge for CUBE.

MPEG, DV, and transcoding..................................... tvbeurope.com There are various MPEG-2 formats. "It is widely recognised that MPEG-24:2:0 is NOT suitable for production due to its lower chroma resolution.However, 4:2:2, in particular the I-frame only structure, may find somelimited applications if minimal picture manipulation is required (wipes anddissolves are OK, DVE movements are not)," says Paul Dubery, productmarketing manager, Tektronix. MPEG's disadvantages also include "cost (theasymmetric nature of MPEG means a more expensive coding process and somesystem design constraints), as well as less acceptable jog/shuttleperformance and less efficient editing operations." But, this doesn't stop Kovalick, and many others, predicting that therewill be just two formats in future: DV and MPEG. "MPEG has been accepted for acquisition (SX), contribution (EBU network,ATM, satellite), distribution (EBU, telco, satellite) and transmission(terrestrial, satellite etc.). MPEG-2 4:2:2P@ML was designed for programmeproduction applications with high bit rates and short GOPs [Groups OfPictures -- how many pictures per MPEG sequence]," says John Ive, directorstrategic planning, Sony. Because of family similarities, he believes quality degradation of decodingand encoding can be avoided by staying within the MPEG family throughoutthe chain. While SX is already MPEG compliant, Sony has also announcedplans to develop a half inch MPEG VTR and disk-based storage, and isworking on VTRs, hybrid and nonlinear systems, transmission systems andcoding/transcoding solutions for MPEG.
