Multimedia information processing system

摘要

In a multimedia information processing system, a relay station (201) comprises: transmission decoding section (500) for reproducing a fixed packets stream (14) from received transmission signal (15) from a transmitter (1001); signal change processing means (900) for executing changing process for the fixed packets stream (14); and transmission coding section (400) for producing a transmission signal (15) corresponding to a characteristic of a transmission line from the fixed packets stream (14). The construction for exchanging signals between different transmission means is simplified. Thus, it is achieved to exchange contents of media between different transmission means by a simple construction.
