Sony, Thomson and others cooperate on "MOLE" technology that prevents signal degradation when MPEG video is encoded and decoded multiple times, such as in studios and in transmission/re-transmission facilities...........

<<April 7, 1998--Thomson Broadcast Systems, Sony Broadcast and Professional
Electronics and Snell & Wilcox today announced their decision to co-operate on MOLE technology.

MOLE technology has been created as part of Snell & Wilcox's extensive MPEG research and development programme and
in co-operation with the British Broadcasting Corporation. Designed for the cost-effective lossless concatenation of MPEG2
bitstreams, MOLE technology offers unprecedented end to end system capabilities both in and beyond the MPEG domain.

Whenever a signal is conventionally MPEG encoded, decoded for further processing and re-encoded, these multiple
processing steps adversely affect signal quality. MOLE technology provides the end-to-end solution.

MPEG encoders and decoders equipped with MOLE can preserve the picture quality of the first encoding with mathematical
precision, through multiple generations of de-coding and re-encoding; and without the expense of using high bit rates to
compensate for deterioration in picture quality. >>
