Abstract :
Measurements using a continuous quality recording method have revealed the extent of quality variations that occur in MPEG2 pictures at low bit rates. Large moving objects in particular can give rise to particularly severe troughs in quality. The complementary characteristics of modelbased coding are examined with a view to a synthesis of the two methods in a switched coder, with possible increased overall coding efficiency.
