Information processor
First Claim
1. An information processor storing a plurality of format engines each for executing data described in a different format, the information processor comprising:
- format engine managing means for pre-defining common states which define operating states of each format engine in a representation common to all the format engines, and managing an operation of each format engine; and
operation control means, provided in correspondence with each format engine, for pre-defining a correspondence between the common states and individual states which define the operating states of each format engine in a representation different for each format engine, and controlling operations of the format engines such that each format engine is in an arbitrary individual state;
wherein;
for changing a format engine to a predetermined common state, the format engine managing means sends a message including common state information indicating the predetermined common state to the operation control means provided in correspondence with the format engine; and
when the message is sent from the format engine managing means, the operation control means controls the format engine such that the format engine is in the individual state corresponding to the common state indicated by the common state information included in the message.

Abstract
An information processor capable of easily dealing with addition or alteration of a format engine is provided. The information processor includes format engine management means and operation control means. The format engine managing means pre-defines common states which define operating states of each format engine in a representation common to all the format engines, and manages an operation of each format engine. The operation control means is provided in correspondence with each format engine, and pre-defines a correspondence between the common states and individual states which define the operating states of each format engine in a representation different for each format engine, and controls operations of the format engines such that each format engine is in an arbitrary individual state.

8. A program executable by a computer of an information processor storing format engines each for executing data described in a different format, wherein the program causes the computer to function as:
-
format engine managing means for pre-defining common states which define operating states of each format engine in a representation common to all the format engines, and managing an operation of each format engine; and
operation control means, provided in correspondence with each format engine, for pre-defining a correspondence between the common states and individual states which define the operating states of each format engine in a representation different for each format engine, and controlling operations of the format engines such that each format engine is in an arbitrary individual state;
wherein;
for changing a format engine to a predetermined common state, the format engine managing means sends a message including common state information indicating the predetermined common state to the operation control means provided in correspondence with the format engine; and
when the message is sent from the format engine managing means, the operation control means controls the format engine such that the format engine is in the individual state corresponding to the common state indicated by the common state information included in the message.
