ABSTRACT:
A data receiving-processing apparatus including a receiver for receiving an extended function program or data transmitted thereto, a processor for processing the received data, a first storage such as a read-only memory for storing a basic program used to execute the data processing and an ID code to identify the apparatus and having a branch for the extended function program, a second storage such as a nonvolatile memory for storing the extended function program in a compressed state, a third storage such as a volatile memory for storing the extended function program in an decompressed state, and a decision maker for making a decision as to whether the ID code has predetermined content. The received data is processed in accordance with the basic program stored in the first storage and, after the extended function program stored in the second storage is read out at the branch in the basic 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 as required.
