Patent ID: 7168015

Claim:
A transport format determination apparatus determining, for each transport channel, transport formats to be used for supplying data every data-arrival-interval, wherein a plurality of transport channels different in data-arrival-interval are free to be multiplexed with each other, and said transport format determination apparatus including: a detecting unit for detecting a fault of data on said plurality of transport channels; and a transport format combination indicator restricting unit for determining at least one first data-arrival-interval of at least one first transport channel, based on a result, from said detecting unit, of detecting fault of data on a second transport channel having a second data-arrival-interval shorter than said at least one first data-arrival-interval, and said transport format combination indicator restricting unit for restricting a candidate of transport format combination indicators to be used for decoding subsequently-received data and for isolating transfer blocks, if a plurality of said transport channels different in data-arrival-interval are multiplexed with each other.
