A data receiving-processing apparatus comprising a means for receiving an extended function program or data transmitted thereto, a means for processing the received data, a first storage means such as a read-only memory for storing a first program used to execute the data processing and having a branch for the extended function program, a second storage means such as a nonvolatile memory for storing the extended function program in a compressed state, a third storage means such as a volatile memory for storing the extended function program in a decompressed state, an ID code storage means for storing an ID code to identify the apparatus, and a decision means for making a decision as to whether the ID code has predetermined content. The received data is processed in accordance with the first program stored in the first storage means and, after the extended function program stored in the second storage means is read out at the branch in the first program, the data is processed in accordance with the extended function program. In this apparatus, a new extended function program can be added at low cost in compliance with requirement. <IMAGE> |
