Abstract
When a transport rate Rs is updated, in the case where the updated transport rate Rs is within a variable range (Rc<Rs<U×Rc, and U>1) defined by a current encoding rate Rc, FEC (Forward Error Correction) data sending rate Rf is updated (Rf=Rs−Rc) without updating the current encoding rate Rc. On the other hand, in the case where an Rc update timer set to three seconds, for example, is timed out, the encoding rate Rc is updated using a minimum value Rs_min of the transport rate up to that time (Rc=V×Rs_min, and 0<V<1). Even when the transport rate Rs greatly varies to be out of the variable range, the encoding rate Rc is updated in the same manner.
