SocietyUs increasing involvement with real-time digital video is creating 
a need to store and transmit huge amounts of data.  MPEG is one of 
several data compression algorithms which can mitigate the costs of 
using huge disk arrays and very large bandwidths without significantly 
degrading signal quality.

Computing the 8x8 2D Discrete Cosine Transform (DCT) is a very time 
consuming process in MPEG encoding.  Santa Clara Univ. Prof. Nam Ling 
will describe an implementation architecture consisting of an 
8-processor array and a transpose RAM.  Each processor is simply a 
fixed point multiply-add unit so that the entire array and RAM can be 
implemented on a single chip.

Motion vector estimation and DPCM are also very compute intensive.  
Yi Tse of Compression Labs will provide an overview of the various 
components of MPEG and then concentrate on the principles of motion 
compensation and some advanced motion prediction modes in MPEG-2.

We will certainly be interested in discussing whether MPEG can be 
improved with the additional use of Parallel Processing.

A discussion of member projects currently underway and other 
issues of interest to entrepreneurs begins at 7:15PM and the main 
meeting starts promptly at 7:45PM at Sun Microsystems at 901 San 
Antonio Road in Palo Alto. This is just off the southbound San 
Antonio exit of 101.  Northbound travelers also exit at San Antonio 
and take the overpass to the other side of 101.

Please be prompt; as usual, we expect a large attendance; don't be 
left out or left standing. There is a $10 fee for non-members and 
members will be admitted free.  Yearly membership fee is $50; 
corporate membership fee is $400/year.
