Abstract

PURPOSE:To prevent overflow and underflow by controlling the number of refleshing within a frame when occupancy ratio of transmission buffer memory is increased. CONSTITUTION:The titled system is the refleshing mode which encodes the input signals between the frames and does not encode them between the frames, and transmits them through the transmission buffer memory to a frame at plural number of times. In figure (a) is a frame synchronizing signal, and in the refleshing mode when the occupancy ratio is in the range of (a)-(b) as shown in (b), its number (n) of refleshment is 6. In case of the occupancy ratio is larger than (b), the refleshing times are varied as (c)-(e) in regular interval control system, and refleshment is omitted at the position of the dotted line such as (f)- (h) in the same position inhibit control system.
