Abstract: A multiplexing digital broadcast system includes a receiving terminal; and a broadcasting station. The receiving terminal includes: a receiving side recording device demodulating a specification digital data selectively specified from a multiplexing digital data transmitted by the broadcasting station to record; a receiving side table recording a position in a data string corresponding to a data unit of the specification digital data in which a demodulation ended in failure; and a communicating device transmitting the position in the data string to the broadcasting station, and wherein the broadcasting station includes: a broadcasting station side recording device recording an original data corresponding to the multiplexing digital data; and a supplemental data transmitting device extracting the specification digital data corresponding to the position in the data string from the original data to transmit to the receiving terminal.

Abstract: A compiler comprises a using register control table by function, a using register extracting unit by function for extracting a using register and a call function name, in every function, based on the intermediate code generated from a source program, and registering the same into the using register control table by function, a using register totaling unit by function for totaling the registers used by a call function called by an interruption function, and newly registering the totaled registers in the using register control table by function as the using registers of the interruption function, and an output unit for adding saving/return codes of a using register of the interruption function to the intermediate code, with reference to the using register control table by function so to generate and supply an assembly program file.
