Abstract

A storage medium stores image data, audio data and processing programs having different reproduction modes, such as recording systems or data format are stored as stream data. When a specific data is to be read out from the stream data, a mode discrimination data is separated from the data to generate mode information indicative of the recording system of the data and the algorithm for reproduction of the data on the basis of the separated mode discrimination data. Based on the mode information, switching of mode is performed to reproduce image data or audio data of one of the reproduction modes among the data recorded with a plurality of mutually distinct reproduction modes, by the processing program. If the processing program is common for reproduction of other data recorded on the storage medium, such processing program is previously stored for use in common for accelerating taking up of the reproduction processing apparatus.

Claims13

Dependent claims

A data processing system, comprising:

a data input interface, coupled to a network, receiving data compressed or encoded from a data storage apparatus via said network;
a bus coupled to said data input interface;
a memory, coupled to said bus, storing at least one processing program for decompressing or decoding data;
and
a processor, coupled to said bus, decompressing and/or decoding said data received from said data storage apparatus based on said processing program stored in said memory when a processing program for decompressing or decoding said data received from said data storage apparatus is coincident with said processing program stored in said memory for every file opening in said data, transferring said processing program from said data storage apparatus to said memory when said processing program for decompressing or decoding said data received from said data storage apparatus is not coincident with said processing program stored in said memory for said every file opening in said data, and decompressing or decoding said data received from said data storage apparatus based on said transferred processing program.
